"I cannot say enough good things about A&W Restoration. They were professional, informative, responsive, and extremely helpful/patient, they answered all of my questions (there were many I might add). They demonstrate a high quality of workmanship; we are thrilled with the final product (roof repair/replacement and gutter replacement). I would highly recommend A&W Restoration, and will continue to utilize their services in the future."

"These guys were great! This project took a while to complete because of weather & tedious nature of having to cut each piece to fit but these guys were good. Kenny, I believe was his name, was foreman and he took every step possible make sure it was done correctly. We had some super hot days to be working on a hot roof but they did it! Any concerns we might of had, they took the time to answer questions and make sure we were happy. The roof turned out beautiful and we get a lot of compliments on it. They are a family owned company with their own employees and take pride in their work. I would not hesitate to hire them again or recommend them to anyone."

"I can’t say enough good things about Accredited Roofing. From start to finish, the experience was outstanding. Their representative Steve was professional, knowledgeable, and incredibly easy to work with. He took the time to explain the process, answered all my questions, and made sure everything was handled smoothly. The restoration team was just as impressive. They showed up on time, worked efficiently, and delivered top-quality workmanship. The attention to detail really stood out, and the final results exceeded my expectations. My property looks amazing, and it’s clear they take pride in their work. If you’re looking for a roofing company you can trust, Accredited Roofing is the real deal. Highly recommend Steve and the entire team!"

Roofing questions, answered by experts

Yes, an underlayment is required for metal roofs, especially when installed over an indoor residential living space. This underlayment acts as a protective barrier between the metal roofing and the roof deck. Common materials include tar, asphalt felt, or woven synthetic polymers. Depending on local building codes, existing shingles in good condition may also suffice. A quality underlayment is crucial as it provides protection against water intrusion, improves energy efficiency through insulation, helps absorb sound, and ultimately extends the lifespan of your roof.

The best roof replacement type depends on your budget and your particular climate, as well as your personal aesthetic. But in general, asphalt shingles are the best roof replacement type for homeowners looking for durability at a budget-friendly price. Asphalt shingles are the most common roofing material—cost-effective, easy to install, lightweight, and the perfect choice for handy homeowners.

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.

Roofers don’t typically replace vent pipes themselves, but they do handle the flashing and seals around vent pipes when working on a roof. During a roof replacement or repair, roofers inspect the vent pipe flashing for damage, replace deteriorated seals, and ensure the pipe is properly integrated into the roofing system to prevent leaks. If the vent pipe itself is cracked or damaged, a plumber is usually required to replace it, while the roofer ensures the roofing components around the pipe remain watertight.

Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.
