"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."

"While removing the old roof, the aluminum coverings on our mansard roof dormers were damaged. The roofing crew attempted to repair the damage but the result was not satisfactory. As compensation they deducted a small amount from the total bill."

Roofing questions, answered by experts

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

You can walk on a TPO roof, but you should only do so when necessary and wear footwear that’s less likely to puncture the surface. If you anticipate needing to frequently walk on your TPO roof, reinforce walkways to protect against punctures. TPO roofing can also be slippery, so in most cases, you’ll want to leave walking on it to the pros.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

Yes, roofers can repair and replace roof trusses. In fact, because trusses are such an important part of your roof’s structure, it’s best to have a roofing contractor deal with a damaged truss. If you try to fix the problem without the right skills or knowledge, your roof could sustain further damage or even collapse.
