James Latter
PRESIDENT
James began roofing in 1980 in Bellevue while still in high school, and worked for two roofing companies over the next 16 years before launching out on his own in 1996. James’ vision for his brand new company was that it would be founded upon the ‘Cornerstone’ of ethical business practices while providing quality workmanship you can trust.
In February 2026, Cornerstone celebrated its 30th year in business. We are a company large enough to handle any of your residential and commercial roofing needs, yet small enough to monitor your project from start to finish to assure your complete satisfaction.
James is CertainTeed Shingle Quality Master certified, and has achieved CertainTeed’s ShingleMaster PREMIER Credential, the highest credential level a company can earn with CertainTeed. Today, James works mostly on the commercial roofing bid requests, and with apartment/ town home/ condominium homeowner associations, and church and school boards on their roof replacement or repair projects.
James and his wife, Tawni, live in Bothell, and have two grown daughters, two sons-in-law, three granddaughters, two grandsons, and one Puggle Cooper. In James’ spare time, you can either find him on a golf course or on a beach in Mexico with a good book.
“My entire experience with Cornerstone was outstanding, from the initial conversation with James Latter, through the quoting process and the actual work done to my roof. The crew completed my job in less time than estimated and they did a wonderful job of cleaning up debris all three days they worked at my home. I am a very satisfied customer. Thank you for an excellent job!”
“My new roof gives me peace of mind. Your owner James was very professional, considerate and kind. Thank you!”
“Cornerstone was recommended by our neighbors and after seeing how beautiful their roof turned out it was a no brainer to go with them. They were professional and timely in the completion of the project and the Owner James was great to work with.”
“Your team executed the project just as outlined when we signed the contract with James. The work was done just as expected in a quick and professional manner. It was a relief to have everything go as expected with no hurdles or surprises along the way.”
“The quote from James was by far the most comprehensive and professional, and the work was completed in a timely fashion.”
