"Kevin and his crew showed up early and got right to work. Finish product is looking great. There was a small issue with a few of the baffles in the attic not being secured correctly and Kevin took care of it quickly. Would definitely recommend JP Carroll."

"We could not be happier with our new metal roof! Customer service was beyond reproach and the company's CEO called at the end to ensure we were satisfied with the finished product. We went with the 26 gauge corrugated roof - outstanding product and the installers were able to flawlessly install the panels on a difficult roof (pitch and bump-outs). I, without reservations, recommend Maine Metal Roofing."

Roofing FAQs, answered by experts

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.

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.

Roof raking can damage shingles if improperly done. Be sure to use a rake that’s designed specifically for removing snow from a roof, and don’t use excessive pressure. Light, consistent pressure to pull down the bulk of the snow is all that’s needed—if you clear right down to the shingles, you’re probably using too much force and risking roof damage.

Wood shake roofs are durable, energy-efficient, and offer a natural aesthetic. Composite options provide similar looks with less maintenance.

Spray foam roofs don’t stand up well to impact, so they won’t last as long as something like a tar and gravel roof and other flat roof materials in areas where extreme weather is common. Due to the reduced durability, you’ll also need more frequent maintenance and repairs for a spray foam roof, and those costs will add up over time. Spray foam roofs are relatively uncommon, so you may also struggle to hire a roofing contractor who can install one.
