"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!"

"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."

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.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

In most cases, below 40 degrees Fahrenheit is too cold to replace a roof. The cold affects the shingles, making it more difficult to adhere them to your roof. It also becomes dangerous for contractors to get up on your roof in the cold weather, as there can be ice and slush causing surfaces to become slippery.

Fall is widely considered the best time of year to replace a roof. The moderate temperatures are ideal for roofing crews to work and for new shingles to seal properly. Additionally, autumn weather is often drier, reducing the risk of weather-related delays compared to the rainier spring season.

While spring is also a viable option, the higher chance of rainfall can slow down the project. The main drawback to a fall installation is that it's the peak season for roofers, which can lead to higher prices and scheduling challenges.

To potentially save money, you could consider scheduling your roof replacement during the summer or winter off-seasons. However, both seasons have significant disadvantages. Extreme summer heat can make shingles too soft to handle, while winter's cold, snow, and ice can create dangerous working conditions and prevent shingles from sealing correctly, as they typically require temperatures above 40-45°F.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.
