"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."

"I reached out to Apollo Roofing for an estimate because I had persistent leaks during the winter. I had called several roofers to get quotes for myself and my husband. Apollo?s estimate was the most reasonable price, and it didn?t compare to any of the other companies we contacted. Sam provided an estimate quickly, efficiently, and was incredibly professional and knowledgeable about roofs. We decided to go with Apollo Roofing, and it was the best decision we?ve ever made. We love our new roof, and we haven?t had any leaks since we had it installed."

"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

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.

A properly installed, high-quality tarp can be left on a roof for up to 90 days. However, this is only a temporary measure and not a substitute for proper roof repair or replacement. Thinner tarps or those exposed to heavy wind and rain may not last the full 90 days, so it's important to monitor the tarp's condition to ensure it continues to protect your roof from the elements.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Most roof leaks occur where shingles meet or where there are sealants or seams in the materials. This is common around skylights and at any point there is a break in the roof such as corners and edges. Roofing materials are incredibly strong and resistant when overlapping, but any change in that can cause gaps where water can enter.

Here are a few tips on how to choose a roofer:

  • Get everything in writing

  • Ask for insurance, license, and bond, then verify them

  • Check their reviews 

  • Ask for recommendations

  • Get multiple quotes

You’ll also want to watch out for any red flags like:

  • Pushy sales tactics

  • Not willing to show necessary documentation

  • Bad gut instincts
