"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."

"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 number of roof vents necessary for a 2,000-square-foot house depends on several factors. The calculation depends on the net free area within the attic and whether your municipality requires a 1/150 or a 1/300 ratio of venting square feet to attic square feet. If you install vents with a square-foot opening of one, you'll need either 14 or seven exhaust vents and an equal square-foot amount of intake vents.

The most important thing to remember when laying shingles is to work from the bottom of the slope to the top. This leaves you with a top overlap that directs runoff from one row to the next until it reaches the eave for disposal. You should also make sure you follow the manufacturer's instructions and the local building code for nailing patterns and frequency so all of your hard work stays put through varying weather conditions.

A chimney cap costs about $300 on average to install, with prices ranging from $75 to $1,000. The final cost depends on several factors, including the professional you hire, the accessibility of your chimney, the cap's material and size, whether any repairs are needed, and if it requires custom fabrication. Chimney caps are usually made from galvanized steel, stainless steel, or copper. Copper caps are the most expensive, followed by stainless steel and then galvanized steel. Excluding labor, average material costs are around $100 for galvanized steel, $250 for stainless steel, and $600 for copper. You may also face additional costs, such as hiring a chimney sweep to clean the chimney before the cap is installed.

Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.

Rubber shingles last for around 30 years, on average, and some can last for and include warranties for up to 50 years. Rubber roof shingles are more expensive than asphalt shingles, but they can last up to twice as long, meaning they provide more value in the long run. Just keep in mind that rubber roofs often require more maintenance than asphalt shingle roofs, including routine cleaning to avoid mold growth. Ask the roofer who installed your roof for an estimate for routine cleaning, if necessary.
