"Steve showed up promptly, quoted a fair price , and did a great job: copper chimney cap and waterproofing joints. While he was on the roof, he inspected the rest of the roof without being asked to and told me that no further repairs were required."

"I had a great experience with Perry's roofing. My roof has spung a leak and needed replacement. I had a precise, professional quote within 48 hours. Once we went ahead with Perry's, we had a team on site by the end of the week, and the work was done in 1 day. 24 hours after the installation was complete, we had one of the worst thunder storms of the season. The new roof held beautifully. When I go to do my next roofing job, I will be calling Perry's roofing first."

Roofing FAQs, answered by experts

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

Mansard roofs are still popular in Paris, where they originated, and throughout France. In the United States, you can find mansard roofs on some older buildings in Manhattan. The architecture also appears on some Victorian and Colonial-style homes. There are pockets of homes with mansard roofs in New York City and Los Angeles, where they were once more popular than they are today.

Metal roofs last for between 50 and 70 years, and asphalt roofs last for between 20 and 25 years, with some lasting as long as 30 years. In most cases, you’ll get double the life or more out of a metal roof than you would from a shingle roof, which helps make the higher cost of a metal roof more manageable.

Yes, you can walk on torch down roofing. It is durable and tear-resistant enough to handle that kind of low-level wear. Remember that torch down roofing can get uncomfortably hot in certain climates. Dark roofing absorbs heat and can burn bare feet. If you want to use a roof deck for lounging, you may want to install a lighter-colored PVC membrane.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.
