The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.

The ideal color for your roof depends entirely on your preference. If you’re looking for something classic, gray, brown, and black will rarely steer you wrong. A roof with a pop of color like green or red can be sophisticated and elegant when paired with the right colored siding. Decide what vibe you’re looking for and choose a color palette that suits you.

Tipping your roofer or their crew is not customary or expected, but it is always appreciated. It is entirely up to you whether you want to give them extra money for their work. If you feel they have done an exceptional job, a tip can be a nice gesture. As an alternative way to show appreciation, you can provide coffee, breakfast, drinks, or grab-and-go snacks like cookies or doughnuts.
