"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

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

The formula for calculating how many squares of roofing you need is pretty easy. Take the total amount of square footage and divide it by 100. With this formula in mind, a 2,000-square-foot roof would require 20 squares of roofing material to adequately cover it.

The four types of roof sheathing are plywood, oriented strand board (OSB), planks, and tone-and-groove boards. The overwhelming majority of homes use the first two (especially OSB) and the other two are not often seen outside of special use cases. Methods of sheathing include solid sheathing, open sheathing where there are gaps, and plank sheathing. Most roofs are solid sheathing.

Many roofers remove satellite dishes as part of their services, especially during roof repairs or replacements. However, they typically won’t reconnect or reinstall the dish. If you no longer need the dish, roofers can dispose of it, but for reuse, you may need a satellite technician to handle reinstallation.

The most crucial roof-strengthening method is achievable by following proper construction methods and guidelines from the start. To strengthen an existing roof, framers and DIYers can add hurricane ties or straps to the structure, sister rafters and other framing or truss members, or install additional fasteners or adhesives where necessary.
