“I highly recommend Cornerstone Roofing for their quality service — friendly, responsive, neat, and efficient. While getting ready to move during a heat wave, I realized how inadequate the ventilation options in my new home were. Neighbors recommended I contact Cornerstone Roofing to replace my fixed skylights with some that open. Sam came out the next day to discuss my options. I also asked about a solar attic fan for the garage, and he suggested a way to improve the intake venting there, as well. Although they were scheduling 3 weeks out, Sam said he’d try to squeeze me in, because he agreed, the house was extremely hot. A week later, he called to ask if they could come the next day! The installer arrived on time, explained what he would do, and cheerfully set about his work, despite the glaring sun. I was most impressed that he was careful to leave no marks on my freshly painted attic access panel. He also helped me get the closet shelf and rod reinstalled after his attic work was complete. All in all, excellent service with a personal touch. And the ventilation in my house and garage is much improved, too!” – Yelp 5 Star Review, Bothell, WA

“Cornerstone was great. They squeezed me in for an emergency Repair and then were able to get to my full Re-Roof sooner than expected. I will gladly refer them to friends in the future.”
