"Custom Roofers III, had the lowest bid for our flat roof. We didn't realize they weren't going to take off old roof. Put new materials right over old roof. Not a fan of that decision."

Roofing questions, answered by experts

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.

Yes, it’s possible to replace drip edge flashing without removing shingles, but it’s not a good idea. You’ll have to lift the bottom shingles up to remove the old drip edge, install the new material, and then lay the lifted roofing material over the new drip edge. Bending roof shingles can cause damage, and if you have ongoing issues with roof leaks that prompt drip edge replacement, it’s a good idea to consider a roof and drip edge replacement to avoid ongoing issues.

Architectural shingles and impact-resistant shingles aren’t mutually exclusive, which means some architectural shingles are impact-resistant shingles. Architectural shingles are thicker and more durable than standard 3-tab shingles, and they become even stronger when they also have high impact resistance and wind resistance ratings. The most durable shingles for areas with extreme weather are architectural or luxury shingles that have a Class-4 impact resistance and a Class-H wind resistance that can stand up to winds reaching 150 mph.

Many states require roofers to be licensed, and some states don’t mandate licensing. You can use Angi’s state licensing tool to check if a roofing company holds the proper licensing for your area. A licensed roofing contractor will provide reliable roof installation service, leading to a reduced risk of leaks in the future, which can be expensive to repair. Paying more for a licensed roofer upfront often means paying less over time.

Copper roofing works well in all kinds of climates, but it’s ideal in humid climates because it naturally repels fungus, moss, and algae. This makes it one of the best roofing options for Cape Cod homes in the Northeast, as well as homes in the humid southern states and snowy northern states. That said, copper is vulnerable to thermal expansion. If you live in a climate that has extreme temperature changes, your contractor will need to consider this during the installation process.
