"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 have a Victorian style home with a very steep, high-pitch roof, so finding a roofer willing to actually get up there and inspect it properly was not easy. Max with Imperia Roofing was the only one who didn?t just look from the ground. He got up on the roof himself, checked everything in detail, and explained exactly what needed to be done. He was great to work with from start to finish, very straightforward and easy to communicate with. The work was performed quickly, stayed on schedule, and the finished roof came out great. If you have a steep roof or a more complicated project like ours, I highly recommend Max and Imperia Roofing. Don?t look elsewhere."

"Tesla came by and said that I need a new roof before they can install the solar. Jacob was referred to me and came by the next day and helped me a lot to understand the roofing system to install leak barrier under roof to seal the screws drilled in"

"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

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.

Roofers don’t typically replace vent pipes themselves, but they do handle the flashing and seals around vent pipes when working on a roof. During a roof replacement or repair, roofers inspect the vent pipe flashing for damage, replace deteriorated seals, and ensure the pipe is properly integrated into the roofing system to prevent leaks. If the vent pipe itself is cracked or damaged, a plumber is usually required to replace it, while the roofer ensures the roofing components around the pipe remain watertight.

Yes, a new roof will add value to your home, often providing a return on investment (ROI) of between 60% and 70%. Not only will a new roof boost curb appeal, but savvy homebuyers will also know that a new roof means they won’t have to worry about roof leaks and related damage for years after closing. They’ll also know that they’ll save money by potentially having decades before they need to worry about paying for repairs or replacement.

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.

Yes, gable vents can let water in. That being said, this usually only occurs during extreme conditions like heavy rainfall. You can prevent water from entering through gable vents by adding a screen that traps the water before it can enter.
