Cornerstone Roofing

TOP RATED FOR QUALITY

We are a company large enough to handle any of your roofing needs, yet small enough to monitor your project from start to finish to assure your complete satisfaction. Since 1996, and with our same Owner for over 30 years, we are dedicated to providing our clients with a dependable roof system through high quality workmanship, superior materials, and a premium level of customer service.

“Cornerstone Roofing exceeded our expectations with our roof replacement. With such a significant investment, we diligently sought quotes over a span of three years as our roof approached the end of its lifespan. Throughout this process, Cornerstone consistently stood out as a top contender, thanks to their great reviews and transparent, honest professional guidance. We were particularly impressed by the owner’s upfront assessment, which accurately estimated that we had another 2-3 years left before replacement became necessary, rather than rushing us into a decision. It’s refreshing in today’s sales landscape. … From the initial quoting process to ongoing communication throughout the project, every aspect of our experience with CSR was nothing short of outstanding. We are delighted with our new roof and grateful that we entrusted CSR to oversee such a smooth process.”

Cornerstone was awesome. Michael came out and gave me an estimate that was fair and showed great attention to detail. They were flexible when I injured myself and had to delay the job for a while and still honored their original estimate. Brianda was communicative and helpful getting scheduled and Andiego did an awesome job on the actual repair up on the roof. We had a few vents replaced and several nails sealed that hadn't been driven in properly during the initial roof install. Based on this experience, I trust them to do an awesome job when it comes time to actually do a full roof replacement later!

“I enjoyed working with Cornerstone Roofing. The process was quick and seamless. Communication from Dave L., Kristy, Jim (construction manager) & Jack (field superintendent) was excellent. I especially appreciated the text updates from Jack who kept me informed & addressed my questions promptly even on a Sunday! Many thanks to the incredibly hardworking crew who worked long hours to complete the roof within 2 days.

We recently bought a house that was built in 2000. We weren't sure if the roof was the original one from 2000. We got a roof replacement quote from one company with the cheapest option being $22,000. We wanted multiple quotes so, after looking at Yelp reviews, we contacted Cornerstone Roofing. Mike (from Cornerstone) came today to give us a quote. After getting up on the roof, he came down and let us know that our roof looks great and does not need to be replaced. He explained what materials he saw that showed it was a newer roof and listed all the features that were put in when it was replaced. He gave us the name of the shingle company and let us know we probably still had a warranty through them. He even followed up after he came, saying he looked up satellite images and the roof was probably replaced in 2016/2017. I had already contacted the shingle company to ask about the warranty and, Mike was right, the roof had been replaced in 2016. We now have a warranty we can use if an issue with our roof comes up and we know that we do not need to replace our roof for many years. Mike saved us a minimum of $22,000. I can't speak to the quality of Cornerstone Roofing's work (only because we didn't end up needing it) but I can speak to the honesty, integrity and knowledge of their employees.

I was highly impressed with the Cornerstone Roofing team from start to finish! I reached out to about 7 different local roofing companies – including Cornerstone – for bids on a full roof replacement project. Big shout-out to Mike Little, our Cornerstone estimator, who provided us with all the details we needed to review multiple quotes and make an informed decision on next steps. I never felt any pressure to choose Cornerstone (unlike with some other roofing companies), but we ultimately went with them because their pricing, scope of work, customer service, and responsiveness over email/phone calls were all exceptional and stood above their competition. They replaced our whole roof, installed some new sheathing, updated a skylight, improved our venting system, and did a magnetic sweep of the property before they left at project completion. The crew worked hard, interacted with us kindly, cleaned up after themselves, and finished the project in 2 days. They were prompt the whole way through! They also checked in with me on a couple occasions to make sure everything was progressing as desired and to give me a run-down of the updated price estimate before they installed new sheathing. Big shout-out to Vicente and his crew, along with Jim and Diego, for all the great work, for keeping the project on track, for communicating so professionally along the way, and for the helpful QC checks at the end of the week. The new roof looks great, and I'd 100% recommend Cornerstone to anyone else considering roof work. They'll be at the top of my list for any future roofing needs, too! UPDATE TO PRIOR REVIEW: I also wanted to give a special shout-out to Kristy for all her help with permit-related documentation for this roof update! She was exceptionally communicative and responsive over phone and email, and professionally and kindly answered all of my many questions along the way. Thank you, Kristy, for all your help – you rock at your job and made things really easy!

I’m so glad we found Cornerstone. They run a tight ship. Every person we dealt with (Michael Little, Jack, crew, inspector, Pete Sullivan, billing) was so professional, courteous, and coordinated. Very impressed with the operation—a dream to work with. I especially want to call out Michael’s patience with us and all our questions in the sales process. We felt he never pressured us and always advised based on what he would do if it were his own home. We felt like we could trust him. I would recommend Cornerstone to anyone for shingle roof replacement!!!

I recently had my 30 yr roof replaced. I met with Steven Hassan and he quickly gave me recommendations and options after his review of my home. We decided on the product and correct path. He quickly got me a detailed scope and within two weeks the job was done…and that was waiting for weather days in February. In just a few short days we had a beautiful new roof and the work and detail was just as described. Quality work and effort from this team.

Cornerstone Roofing did an amazing job. They replaced three sections of the roof to solve a leak problem. Everyone at the company kept me informed of the process and timing. The only reminder they needed from me was to send the completed photos. The "On the Roof" crew was wonderful. They waited on site for one whole day hoping the weather would clear, but it never cleared enough to start. The next two days the weather was perfect - amazing for February. The first day a crew of three worked nine hours to have the roof cleared and sealed for the night. Their prep work was better than expected. They had thick plastic sheeting on the ground and plywood up against the garage doors to protect them from anything that might bounce against them. After removing the two skylights they immediately covered the openings. At night they replaced the skylights over the temporary covers. The next day the crew was down to two. They worked for six solid hours to lay the shingles and clean up the area before taking a break. I'm sure they wanted to get the job done before any unexpected rain showers. On both days they did a great job of cleaning both the roof and ground areas. On the workmanship side of the project they were careful and exact. They replaced, sealed, and painted all the plumbing vents and gas furnace chimney. The roof looks great too. Be sure to get an estimate from Cornerstone Roofing if you need a repair or replacement.

Cornerstone Roofing has the best roofing material along with a 50 yr guarantee. The crew was very professional, very competent and did a great job cleaning up after and leaving everything as it was before they started. Cornerstone came from a friends recommendation who use to work with them. Everything he said was correct about them being very competent and reliable. The roof is the highest point in our house and not self serviceable. It's really important we get a quality reliable roof along with a company that backs their workmanship. And they are really nice people to work with.

Cornerstone Roofing did a terrific job from start to finish with replacing our roof. I requested 3 free quotes from well-respected roofers and Cornerstone’s was the most prompt and by far the most professional and detailed. And it was considerably less money than the competition. The staff was great at communication throughout the process, including when needing to reschedule due to rain. And at the end, when the recent rain produced mud splatters on some of our windows, they went above and beyond to arrange cleaning. One note is to make sure to request photos of the finished roof from the manager on the day the roof is QC inspected (easier for submitting proof to insurance, which resulting in a premium deduction). I highly recommend this company.

I had used Cornerstone a few years back to re-roof our front porch to address a leak that developed. That experience was positive, so we reached out to get a quote to replace our entire roof as it was reaching the end of its lifespan. My next-door neighbor and I both requested quotes from Cornerstone for our roof replacements. Our estimates were very thorough, detailed, and delivered quickly. My neighbor's brother-in-law works in the construction industry and when asked about Cornerstone, he commented that they have a great reputation and that others in the industry had used them for roofing work. Leading up to the start of construction, the construction manager detailed what to expect during the work, when materials would arrive, and when the work should be completed. The construction crew arrived on time each day and put in a tremendous amount of work. They were professional, courteous, and did meticulous cleanup after the end of the day. They worked so hard that our old roof was removed and the new one replaced in just a day and a half. Our new roof looks amazing, and has numerous upgrades over the original roof. I would highly recommend Cornerstone for your roofing needs.

Cornerstone Roofing installed a new roof on our home and did an exceptional job. From the first meeting with the estimator to the ongoing communication with the company about the schedule, everyone was polite, respectful, and on time. Our estimator did not try to upsell us on their products and was thorough when providing us information about our various choices. We had an old cedar shake roof that needed to be removed with underlying plywood decking also needing replacement. When ripping off the old roof, one of our first floor screens ripped and the company quickly and seamlessly honored the pricing for its replacement. The customer service was exceptional. The roofers were careful to protect our plants and shrubs and did a fine job cleaning up each day. Our new roof looks great--we purchased the Presidential Shake TL (an asphalt composite) with an exceptional warranty. We are very pleased and happy that we used Cornerstone.

Cornerstone just finished our conversion from cedar shake to comp. During the day our house was definitely a construction site but every evening all debris was cleaned up. The whole experience from the initial sales visit, demo, install, final quality check and the admin team was excellent. Even a couple surprise reduced costs on our skylights on the final invoice. Profesional, courteous and thorough is my best description. Thier pricing was also very competitive.

They were recommended to me by multiple property owners and the job was really well done with great respect for our property: tarps over deck, daily sweeps for trash, always available for questions, etc. Trevor Smith was very quick to answer any questions and make sure I was completely satisfied.

We had a leak in our roof and called the day after Christmas. Honestly, we didn't have high expectations as it's difficult to find someone to do a roof repair as most companies aren't interested in small jobs, and it being a holiday week we expected to have a difficult time finding someone. However, less than an hour after we called a person showed up (sorry I don't remember his name ) and assessed the situation. He said he would return around 2:00 to attempt to fix the leak as it was forecasted to stop raining at that time. Well, at 1:50 he showed up and got right to work. He spent about an hour working, finished the job, and cleaned. Communication with the office was great, and the price was very reasonable. Overall we had a great experience with Cornerstone.

"I would highly recommend this company. In the quote process, they were the only service who used drones to thoroughly inspect our roof. Again, they were the only company who looked inside our crawl space of the roof to warn us of potential issues and maybe extra expense. Thankfully there was none. Dave the estimator, was not pushy and took time to educate us. They have done at least 8 houses in our street and all neighbors gave them high praises. This was my final decision breaker. They did warn me that often when they take off a roof there might be some boarding that is water damaged, but they would not know until they took off the roof. They bought 5 pieces of plywood just in case, to the job site on the day. The extra cost for that was minimal, and we did not have the job held up while they searched for hardware stores. This is a very experienced crowd that has a team behind it, each of whom does their individual job in an exemplary fashion. The roofers themselves had been together for ear and were the hardest workers. The place was left in a spotless condition."

We had 10 buildings in our Condo HOA needing roofs. We received 6 bids and chose Cornerstone as they were the most professional, helpful and accommodating. Cost was also favorable and absolute, unlike other bids, that had extras not included. We were always informed of what to expect, everyone in the company was committed and followed up on every call, and need We had. Work was impeccable, clean up was as well and all condo owners were very satisfied. This is a rare company these days, where their word and their work was better than any other contractors of any type. If there were higher ratings than 5 stars, this company earned them!

Cornerstone was exceptional with our roof replacement. We had obtained quotes from several roofing companies, and liked Cornerstone the best. Their salesperson Dave was very knowledgeable and transparent. He took care to outline the pros and cons of repair vs replacement and made sure didn't feel rushed into any decision. This company has been around a long time, and it's apparent they take the long view with maintaining client trust. Cornerstone offered a variety of roof shingles from different leading companies, which is something not every roof company does. This company came recommended by a friend. Dave was also one of the few salespeople we met who willingly climbed on the roof and into the attic to gauge the work. He recommended a molding company to fix an attic issue, and we're glad that was discovered and handled. Since they're a popular company, we had to wait a month or so for the work which was acceptable to us, and in the meantime they tarped parts of the roof where there was a leak. Craig led the installation of the new roof. Due to icy January conditions, a small area of material got wet and they immediately replaced it to give us peace of mind. They replaced our gutter and attic vents. There was wood under the roof that had to be replaced as well, which they did. The result was a good-looking roof and peace of mind! The company provided referrals to solar panel companies they'd worked with, and we hired one to install panels on our new roof!

Corner Stone Roofing exceeded our expectations with our roof replacement. With such a significant investment, we diligently sought quotes over a span of three years as our roof approached the end of its lifespan. Throughout this process, Corner Stone consistently stood out as a top contender, thanks to their great reviews and transparent, honest professional guidance. We were particularly impressed by the owner's upfront assessment, which accurately estimated that we had another 2-3 years left before replacement became necessary, rather than rushing us into a decision. It's refreshing in today's sales landscape. When the time came to proceed, we confidently chose CSR, and the experience was exceptional. The project presented its challenges, given the steep angles and the unpredictable elements of Rain, Hail, Snow, and Wind, coupled with freezing temperatures in Feb. Nevertheless, the entire crew demonstrated remarkable resilience and skill. Each day, they made significant progress on the new roof, showcasing impressive efficiency. Their efforts were further bolstered by seamless support, with supplies consistently delivered to keep the project moving forward. Well done. From the initial quoting process to ongoing communication throughout the project, every aspect of our experience with CSR was nothing short of outstanding. We are delighted with our new roof and grateful that we entrusted CSR to oversee such a smooth process. Our heartfelt appreciation goes out to the entire team for their dedication, especially in such challenging conditions. We are truly grateful for a job impeccably done.

Cornerstone offers a very professional manner from preparing the quote to completing the project everything goes smoothly as planned. The after-service inspection and follow-up are also excellent. They are not the lowest among all the quotes but I'm glad that I picked them. A very well-organized, professional, efficient, and reliable company. Highly recommended.

Highly recommend CSR. They were great to work with and after the work was completed there was one issue I needed to have them address and they did a great job of working with me to fix the issue. Hopefully I won't need another roof for many years but for anyone who does, I highly recommend working with them.

Rain has returned to Seattle. I noted a drip between my gutters and fascia. I couldn't tell if it was potentially a gutter vs. flashing vs. roof issue. Since what prompted my original roof replacement was a somewhat similar leak I figured I should have it checked out. Called Cornerstone and without hesitation Lenny from the repair division came out to inspect the next day! He felt the flashing/roof work looked good but identified that my gutter nail in that area was back-angled towards the house and thought that water might be running along the nail and seeping in-between the gutter and fascia. While Cornerstone did not replace my gutters with my roof replacement Lenny graciously worked to seal the gutter nail area with silicone where it penetrates the fascia. He also took the time to look at other areas around the house and identified a few more places and helped seal those as well. What I really appreciate is that Cornerstone STOOD BY THEIR PLEDGE TO GUARANTEE THEIR WORKMANSHIP and even went beyond in my case. Further, Lenny clearly cared to help me - he brought his expertise (I wouldn't have thought about a back sloping gutter nail) and what took him just a little bit of time saved me potentially having to have a gutter service come out or try to do it myself (homeowners and ladders can be a bad combo). Lenny could've just said "it's not the roof" and took off but he didn't and he again demonstrated what I originally posted - In my experience, Cornerstone and its employees care about their customer's homes and satisfaction. They go the extra mile because it is the right thing to do. Even after going above and beyond Lenny asked "Is there anything else I can do for you today?". That's great customer service and again reflects well on the culture the company has built. Thanks Cornerstone and Lenny!

This roofing company was our final choice after having multiple companies out. They even offer that you can purchase a warrantee on top of the warrantee that comes with the shingles. Professional, great work and they will do what you need done... Need the decking replaced? They will actually do it. Super happy that this is the company we went with.

Cornerstone Roofing did our roof, they did a great job! We had numerous roofing contractors out to give bids and these guys price was in the ballpark, competitive PLUS they were willing to do the work that needed to be done and replace decking and make repairs as needed. The company has a warantee you can purchase for a good price in addition to there's a warrantee that came with our shinigles- and we actually got it in the mail. I will recommend them to others, so glad we found them! It's nice to deal with HONEST people! Dave the estimator was super great. He was a guy to trust and the price came in within the range it should have according to the estimate.

Responsive, prompt, and more thorough than I could have asked for. We were looking into buying the home we were renting. They had quoted the same house for a new roof 5 years prior, unknown to me, so they shared that recommendation on our first visit, which helped validate the condition and needs very early on. I believe James was our contact's name--absolutely fantastic. The the woman who set up the appointment was incredibly informative and warmly professional. We decided not to buy; but if I ever need a roof I'll be calling Cornerstone.

This business treated our under-1000 square-foot home's re-roofing project as if it was their highest priority. We cannot speak highly-enough of these people, every one stellar, from Kristi in scheduling, Mike the estimator (the nicest yet professional guy), Craig who notified us every step, Juan the final checker, the crew who were so nice and kept an entirely clean site and clean-up. And the whole focus: Our roof and new gutters could not be more attractive and well-done. We are so pleased! What a high bar for any other business out there.

Cornerstone didn't miss a beat when we began the search for a reputable roofing company to replace our old 3-tab shingles. James presented multiple options and went over some necessary ventilation changes, along with offering some overall aesthetic options necessary to accommodate the accented trim around the front of the house. The job commenced 3 weeks later and we are extremely pleased with the outcome, as well as the 5* extended 25 yr. warranty protection. Cornerstone was very responsive, professional, courteous, and the cleanup was spot on from beginning to end. Highly recommended.

I selected a bid from Eastside Roofing out of three bids Spring 2022 because it was $3k less on a $36,000 dollar job. What a mistake. I should have hired Cornerstone in the first place. My next roofing job we needed, I had Cornerstone roof our double wide and deep garage Spring 2023. What a difference a roofer made. The courtesous and respectful salesman had more than 20 years experience on the roofs of houses as part of the crew before selling anything and the company's crew is top notch professional. Here are the differences that came standard with Cornerstone that the other roofer didn't do at all: 1) The ops manager assured the dumbster was ordered, playwood to protect our driveway was placed and I was in agreement with the placement of it. 2) The next day, the ops manager checked in with me in the morning on my doorstep and on time. 3) The crew's first thing to do was to lay plastic on the ground to collect debris. 4) A safety manager showed up not too long after and posted a notice of the nearest medical clinic address and phone and observed for a while. 5) The job was finished on time and no one was at the door to collect a fee. 6) The next week the A/R personnel phoned, was kind and assured I was pleased. They emailed an invocie for the balance. The other roofer scribbled on the original bid. 7) I received a 25 year guarantee with a letter in the mail from Cornerstone asssuring me of the quality of their workmanship and how they back it up. 8) Cornerstone registered my shingles with the manufacture and I received a 30 year guarantee from the manufacture a few weeks later. {all 8 of these things didn't occur with the first job and I had to pay Cornerstone to fix the things the other roofer left behind} Hire them in the first place.

We really lucked out with these guys. My neighbor Greg S. highly recomended them and we're glad he did. The estimator Mike L. came out with a ladder and he wasn't a salesman or snarky. He was very matter of fact and to the point, it was quite refreshing. You could tell he's a construction guy and I don't speak "roofing" so yeah, heading in the right direction. He gave us his suggestion for the shingle type and man was he right. Then he sent us a packet outlining everything with pictures, insurance info, material type etc. Very professional outfit. I'll fast forward to completion...So now the new roof is on and it looks 100%...Then they come out again with a magnetic rolling thing to make sure there's no nails around the house...I thought that was pretty cool but at first I was like "umm why are they here?" Then they come out the next day to do a final inspection!?!? The guy was here for three hours on the roof making sure nothing was missed. Talk about under promising and over delivering. Remember that? Then I get a call from their office verifying our info because they are submitting our warranty info for us. Yes really! This is a no brainer-THANKS CSR-we'll probably add pics this summer after a proper paint job. The before and after will be night and day. 414 167th PL SE Before CSR picture posted*** Ok here's a few added post install and post High Point Gutters leaf guard recommendation-Paint to follow...

“Cornerstone was spot on from beginning to end. Starting with the estimator to the job clean up. They were very thorough & professional. I requested a specific time frame and they were more than accommodating. The first day went like clockwork with the crew showing up right on the quoted time and the dumpster showing up within 5 minutes of the crew. Tear off was done in a day, shingles were delivered and stacked on the roof that same evening and the job was completed the next day. Two skylights were also replaced and are beautiful. I watched several houses in our neighborhood take at least 3-4 days. The project was completed with a roof inspection a couple of days later and I couldn’t be happier. I got estimates from six companies and Cornerstone was who I felt most comfortable with. The whole experience was excellent and I would recommend them to anyone.”

I had received a re-roofing quote from Cornerstone 5 years ago but elected to get a few more years out of our shake roof through cleaning, moss control treatment, and a handful of replacement shakes. With the existing shakes now 21 years old, our house was beyond ready for a new roof, so we contacted Cornerstone again. To select them, I had references from an independent source, looked at other homes they worked on, utilized Angie's List reviews, and reviewed the CertainTeed website. The Cornerstone proposal was very comprehensive and provided us with a lot of confidence our new roof would be installed professionally with no cutting of corners. We found the installation crew to be very conscientious and hard workers. There was one small glitch that the management crew jumped on quickly so as not to be a concern on our part. The final inspection of the roof was done by Juan, who was incredibly meticulous in double-checking to be sure all the terms specified in the contract were complied with (metal flashing and gable vent closures are a couple examples). All-in-all, Cornerstone did not disappoint. We are very pleased with the final product and have received compliments from several walkers going by on the appearance of the new roof and gutters.

Everything about this company is great. On time, zero mess, and the customer service is amazing. We've used them for 2 houses, the second a complete reroof including tons of repair on a rehab we bought in 2001. There was not a single scrap of debris or nail on the ground when they were done. Last year a gutter cleaning company noticed some damage and fascia issues with the gutters. Not related to workmanship at all, just trees too close and had done some damage and the gutter company hadn't used the right hardware all those years ago. I called Cornerstone, James came out and took a look, they did a full day or repairs and despite being 8 years out of warranty, barely charged a thing. Oh, and when we had them out to put a couple of additional vents in the roof when we had bathroom fans installed, same thing. It was a couple of years after we bought it, they came out promptly and did a great job. They have a sister company that did my roof cleaning and moss a few years ago. When I had the gutters done last year the guy couldn't believe the roof was 18 years old. Sorry so long winded, I could go on and on. Let's just say no one else will ever do roofing for me. Thanks guys!

A first class operation from beginning to end. I was quite impressed with everyone from Dave (customer contact, estimator), to the roofing crew, to Juan (final detail work, final inspection & cleanup). Each performed his job with professionalism, and demonstrated competence and attention to detail. Dave reviewed aerial photographs of my house prior to our appointment and had prepared an annotated plan view schematic of my roof - complete with notes about the size and location of skylights, vents, etc. - and a detailed cost estimate. Although now an estimator and customer contact, he had been a roofer for 15 years or so - so is very knowledgeable. He had sample tiles, under-layment fabrics, etc. with him and used these items to highlight the differences in products, describe how Cornerstone would perform the work, how long the work would take, etc. He didn’t try to “hard sell” or push the expensive stuff – saying that the PRO or Premium shingles were likely all that I’d need. He indicated that, for the time being, my roof is fine - that it should be good for few more years. A few days later he provided a detailed competitive estimate complete with photos of the roof and notes about the work. The roofers arrived at the job site each day on time, beavered away into late in the day to quickly remove my old roof and install a new one, and ensured that the job site was tidy after each day's work. After the roofers were finished, Juan (another “ex-roofer”) arrived to perform any needed 'detail' work (trim flashings, etc.), ensure that the site was tidy, and perform a final inspection of the roof with me in tow - to ensure that I was completely satisfied with the materials and work. Highly recommended …

We had a great experience all through the process, and were amazed that Cornerstone was able to remove and replace the roofing in just three days. We got quotes from three roofing companies. Cornerstone was in about the middle of the range of quotes, and had the most detailed outline of work to be done. It was clear to us that they had best thought through all of the potential problem areas. They were able to start work 7 weeks after we got the quote, which was good timing. They kept us appraised of when the work would start and what we needed to do to prepare (remove cars from the garage, etc.). A crew of seven men were here for two days. The first day a roofing supply company delivered the plywood and flashing, and then a Cornerstone crew of seven men removed all of the cement tiles and took multiple dump truck loads to recycling. They also installed plywood over the whole roof. That first day, the crew worked about 12 hours. The operations manager, Craig, came by several times to check progress and handled any questions we had. For example, I was concerned about the insulation coverage in some areas of the roof that was inaccessible from the attic. He assured me that they could add insulation if I would provide it. After the tiles were off, I checked and found that the insulation was OK. The second day, a large crane truck delivered the shingles and put them up on the roof. The Cornerstone crew worked about 13 hours that day, and got the entire roof shingled. They cleaned up all of the debris at the end of each day and blew off grit from inside the garage, the deck, and the driveway. That is one hard-working and competent crew! The third day, just one person worked for about 5 hours, checking all of the work done, and added some flashing and caulking. Another young man came out the next day to do a final cleanup, and used a device to check the entire yard for metal debris, nails, etc. The Cornerstone crew removed some of the old gutters and all of the gutter caps. They contracted with Gutter King to finish the removal and install new gutters and Versa-Guard gutter covers. Craig was able to check with Gutter King to get the right color of gutters. They came out the next week to install the gutters, which took two to three men two days to complete. Our house has clerestory windows with roof areas above and below, and part of the top roof had never had gutters. Gutter King installed new gutters at the proper height around all of the top and lower roof, and added the Versa-Guard covers. They did a superb job, using a machine that bends a sheet of aluminum from a roll to the exact lengths needed. We are extremely pleased with the whole job, and greatly relieved that the leak problems and poor gutters are a thing of the past. Cornerstone has a 25-year transferrable warranty that we purchased, which is also guaranteed by the shingle manufacturer. The house looks great, and we no longer need to worry about window washers cracking tiles!

Building our custom home was a dream come true and one of the best things about it was the quality and customer care by Cornerstone Roofing! We could not be any happier with our new roof, it's perfect! Incredible from beginning to end! I highly recommend them!

CSR deserves top marks. They are well organized and well coordinated and the 4 people I dealt with (Kristy - office, Dave - estimator, Craig - operation mgr, and Juan - followup) all had obvious communication and customer service skills. Estimator Dave took his time, was very knowledgeable and willingly shared his knowledge; he was sensitive to attributes of older houses and willingly provided prices on several different options. He sold me on the company without being a typical salesman. Written materials (proposal estimates, agreements, warranty, etc.) were professional and clearly understood.

Everyone @ CSR from Jim,Bill,Sara and Craig in the office to their roofing crew that did our roof late last summer demonstrated a high degree in professionalism from quoting the project thru completing the work on time without incident. Their field crew used the proper safety equipment and kept the project clean everyday by depositing all the old roof material in debris dumpsters. We would highly recommend CSR for your roof or reroof project. We received no negative feedback from the neighbors,infact receiving all very nice compliments on the new roof. CSR started when they said and completed as promised. Great job CSR team,Thank you...Tom & Jean,Mill Creek

Dave, our estimator, is very knowledgeable and very professional. He inspected the roof and attic thoroughly and the proposal package is the most comprehensive. He answered various questions so promptly. We like that there is an optional 25-year extended warranty and the list of references is provided up front. However, we decided to go with another bid that betters match our need for the type of roof venting system and budget. I highly recommend Cornerstone Roofing though.

We did not use this contractor. Mike was prompt, professional, listened to what our needs were and provided a detailed proposal in a timely manner that was competitive with other Angie's List roofing contractors that were vetted. The scope of our project was extensive and he was responsive in answering questions. In the end, the contractor we selected performed a roof repair 5 years ago on our home and we were happy with the quality and results so we decided to move forward with the contractor we used before.

We are happy to give Cornerstone Roofing our sincere recommendation. They made the entire re-roofing experience pretty easy. From the first appointment with the estimator, to the final clean up and walk through, their entire team handled themselves as true professionals. To a person, everyone we interacted with showed a desire to get the job done correctly, and with enthusiasm. We had many questions before, during and after the job, and they were always very responsive and helpful. Upon completion there were a few items that popped up and we asked if they could recommend a company to assist. To our delight, they went above and beyond and took care of the issues themselves without hesitation. Not having to hassle with those last few items was terrific. Because our project began in November, the weather was not great and we did experience a few delays. Weather delays aside, they are pretty busy and the wait was frustrating (almost three months), but they are worth the wait.

The team was a very hard working team since the moss buildup was pretty bad. After spreading the dust, the team moved on. But moss was sill noticed and the company cheerfully scheduled the team back to do finish the job. Why, do you ask, did I give them top ratings when they had to return? It was their attitude of taking care of the customer that put them up there at the tops. Call them back? No problem and project was finished very satisfactorily.

The project went well considering it was done around the first real storm we had in November. They also included more in their bid than other roofing companies we contacted (for example, the vent stack for our heating system was old and rusting, they replaced it and painted it to match the roof. Other companies suggested we have someone else replace it). We were very impressed with the clean up they did and also with the gentleman who did the final inspection. The only issue we had was a communication issue. The roofers couldn't come one day, which we did not have a problem with. The problem we had was that we had to call and email to find out what was going on. And we waited till late afternoon to do that so there was plenty of time for someone to contact us.

Great. Dave the estimator met with us and gave us a very thorough, timely estimate and promptly answered all of our follow-up questions. We chose Cornerstone because of Dave and a referral from a friend. The crew was very hard working and competent. Everyone we talked to was extremely helpful and friendly. The majority of the job was completed in three and a half days. Craig, the production manager, promptly answered our questions. A follow up company inspector did a very thorough inspection of the new roof and then with another crew member came back and replaced additional old failing flashing that was discovered by the crew. The new roof looks great!

Provided quick, thorough estimate. Crew showed up on time, was polite and performed excellent work. Job foreman provided free assistance in designed custom venting system for my multi-pitch roof to prevent future moisture problems due to lack of adequate ventilation. (which was the cause of the roof degradation and subsequent replacement). Quote was not lowest.

Their proposal process is very clear and easy to understand. They recommended the best way to do the job, and showed alternatives that made comparisons easier with other bids. They were competitive on price, but the distinguishing comment is their workmanship, professionalism on the jobsite, job clean up, invoicing, and customer care followup. Excellent work. Highly recommended.

A professional job delivering on time and quality. Efficient operation that provided the lien release from the product supplier. I felt good about the price as well and the roof looks terrific! Hiring a roofing contractor is hard especially when it's your first time and there are so many out there. I think I got lucky with Cornerstone.

They did a terrific job on our reroof! Tore out the old composition roof, installed the new one, it was complete in the 2-days allotted, they were quiet (well, as quiet as a roof job can be!), courteous of my plants, and left the place neat and clean afterwards... Would highly recommend CornerStone, they were great from start to finish.

I am absolutely thrilled with my experience with Cornerstone Roofing! They are very professional and they had the best estimates. The job was done quickly and done right. They even did more work than was in the original estimate and did not charge extra. I would recommend them to anyone who needs a roofing job. They did not pay me for this endorsment.
