"A recent storm blew a few shingles off our roof in San Carlos and we wanted to get it fixed right away. Max with Imperia Roofing inspected the roof and showed us the areas that needed repair. The crew handled everything quickly and the roof looks great again."

"I discovered a small leak in our garage roof. Lifetime Roofing was quick to send a tech to look at the problem. They discovered that the problem was with one of the vents in the roof and not the roof and apply a fix. Hope it works, but the service was quick, honest and communication was great. Thank you Tony!"

"Sam was exceptional and very thoughtful as a project manager. He was very caring and honest and took care of some repairs on the roof himself. He walked us through the process, and made sure we were aware of everything going on. I reccomend Platinum Roofing and Retrofit to everyone who wants honest and quality work! Thank you guys!"
