"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!"

"Ken Armstrong gave a prompt response and appointment made. Thorough inspection advising that the 18 year old composite shingle roof was in good shape, but quoted anyway. Will definitely contact the supplier again in case of roof questions or service."

"We recently had our roof replaced by ODR Roofing, and I couldn’t be happier with the experience. From the start, communication was excellent—Oscar was incredibly helpful and kept us updated at every step of the process. He took the time to explain our options, gave thoughtful recommendations, and made sure we felt confident in our decisions. The entire project was handled quickly and efficiently without compromising on quality. The workmanship was outstanding, and the attention to detail really showed in the final result. What could have been a stressful project turned out to be smooth and worry-free thanks to their professionalism and reliability. I highly recommend ODR Roofing for anyone looking for a seamless, high-quality roof replacement with top-notch customer service."

"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!"

Roofing questions, answered by experts

You can use silicone caulk around the upper lip of your roof vent boot to seal it temporarily, or you can slide a repair sleeve over the roof vent and old vent boot to stop air and water leaks temporarily. However, these aren’t permanent solutions, so you should always hire a professional to come out and replace the roof vent boot for a long-lasting fix and peace of mind.

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.

While two-layer torch down roofs are easier to install than three-layer roofing, it is best not to DIY the installation. Torch down roofs require expert knowledge of the application process to get it right the first time and prevent leaks or poor craftsmanship, not to mention that roof work can be dangerous.

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

Some people prefer to use connectors consisting of galvanized metal to replace the birdsmouth cuts on the rafter board. Common names for these metal pieces include hurricane ties and variable-pitch connectors. Making birdsmouth cuts is more cost-effective than purchasing these connectors for each rafter. However, because making large birdsmouth cuts to accommodate extra-wide exterior walls can weaken the rafter, a connector may be the better option in some cases.
