"We had our roof replaced with GAF shingles by American Cool Roofing and the whole process was excellent. The crew was professional, efficient, and finished the job on time. The roof looks amazing and the quality of the work is very noticeable. Hailey provided outstanding customer service and kept us informed throughout the entire project. Highly recommend them!"

"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!"

"I hired them twice. First to add gutters to my she shed. Took a while to schedule because they are very busy, but I wasn't in a hurry and they came when scheduled and did a great job. The second was to replace a section of my roof that was leaking and remove a stove and replace with a sun tunnel. Again, some delays in scheduling, but it was close to the holidays. The work was very good though a little pricey - but what isn't these days."

Roofing questions, answered by experts

Whether replacing the entire roof or just installing roof shingle replacements in small areas, always pull up the old roof shingles. While you can technically put new roof shingles (but not other roof materials) over old shingles, this can add weight strain to the roof and prevent the new shingles from securing properly to the roof.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.

The best way to check if a roofing company is legit is by asking the roofer for their license number. They should have no issue providing you with this information if they’re legitimate. You can also look to see if they have an online presence, read reviews, and ask contractors you’ve worked with before if they know the roofing company.

Walking on any roofing material is dangerous, so you should avoid it if you can, but if the need arises, you should know that you can walk on a concrete tile roof without damaging it. Try to step on the bottom portions of the tile that are supported by the lower layer, and distribute your weight evenly across both feet and hands, if possible.
