"This is the second time we use Richard and his team at Federal Building & Roofing, and they have been excellent. This time, due to the many homes with roof damage from the heavy winds/rain, it took a bit longer to schedule, but he got it done on a Saturday, and right in time before more rain. Professional, Good Quality Work and Dependable."

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

"David from Clearview Roofing was fantastic in helping replace the roof at my daycare center. We had a huge leak, and he was incredibly speedy with the repairs. He took care of everything from A to Z, making the whole process smooth and stress-free. Highly recommend!"

"Brad from Lifetime Roofing was great to work with . They came onetime and removed and installed a flat roof and a shingle roof. They had to come back out to fix a couple of things with the flat roof and flashing. Throughout the process Brad and Vito managed the project well and communicated regularly. I would recommend them."

Roofing questions, answered by experts

Roof blistering and hail damage are different in their physical appearance. Blistering, often caused by inadequate ventilation, low-quality material, and improper installation, looks like large, irregular bubbles popping out of your roof. Meanwhile, hail damage is usually circular or oval dents entering your roof and often follows the same path as the hail storm.

In general, you should consider replacing your roof if more than 30% of it is damaged. This includes several missing shingles, large spots of granule loss, extreme curling or cracking, structural damage to the roof's decking, or multiple areas of leaks. All of these issues could indicate compromised structural integrity that requires roof replacement.

A metal roof can last anywhere from 15 to over 100 years, with an average of 50 years, depending on the material, installation, and environment. The specific metal is a key factor: aluminum roofs may last 20 to 45 years, while steel can last 30 to 60 years. Tin can last for up to 75 years, and more durable options like zinc, stainless steel, and copper can last from 80 to over 100 years. Factors that can shorten a metal roof's lifespan include living in a coastal region with corrosive salt air, improper installation (such as laying over old shingles), and failing to inspect and replace fasteners, which may wear out before the panels.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.

It’s the reverse of home de-winterization. To winterize, you purge your plumbing system (including your water heater and all piping) of water. Some experts also recommend filling fixtures with an antifreeze solution. Other tasks involve winterizing sprinklers, sealing foundation vents, check weatherproofing around doors and windows, and more.
