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 2023, we will be entering our 27th year in business. Cornerstone Roofing has grown from a team of five in 1996 to more than fifty today. Amidst the growth, James, along with Bill, created a roofing-specific web based software program that helps Cornerstone and other roofing companies  manage roofing projects from the initial CAD drawing program to the proposal creation, material list, scheduling, and final job costing.

James is CertainTeed Shingle Quality Master certified, and has achieved CertainTeed Roofing’s SELECT ShingleMaster Tenured Member status, the highest credential level a company can earn with CertainTeed. Today, James works mostly on the commercial roofing bid requests and works with homeowner associations, church and school boards, and apartment/ town home/ condominium associations.

James and his wife, Tawni, live in Bothell, and have two grown daughters, two sons-in-law, three adorable granddaughters, and two Puggles. 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!”

“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.”

Everett, WA Homeowner | April 2015

“The quote from James was by far the most comprehensive and professional, and the work was completed in a timely fashion.”
