"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!"

"All went well, roof looks great! People walked in the neighborhood and would comment that the progress was looking good. I picked Hoyt out for 4 bids. The city inspector said when I asked him if they did a good job, he said yes and he would recommend them."

"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

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.

The principal, common, and auxiliary rafters are the most frequently used types of rafters. Principal rafters are large and typically appear toward the edges of the roof. Common rafters are smaller than principal rafters. Some people may use a mix of common and principal rafters. The auxiliary rafter is not common, but it provides extra reinforcement for a principal rafter on a large building.

A roof's ability to handle snow depends on its strength and the snow's weight, as wet snow is much heavier than dry, fluffy snow. While designs in snowy regions often allow for 35 to 50 pounds per square foot, a general guideline is that a typical roof can withstand about four feet of fresh snow, two feet of packed snow, or just one inch of ice. Factors like the roof's age, slope, and support structure also affect its capacity; newer, sloped roofs generally hold more weight than older, flat ones. Ice and ice dams add significant, dangerous weight. Because capacity varies, it is best to contact a professional roofing contractor or the original builder to determine the maximum snow load for your specific home.

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

Yes, copper roof strips can help prevent shingle damage and are an alternative to algae-resistant shingles. They work in a similar way: they release copper ions that interfere with algae, moss, and other plant growth. Algae feeds on limestone in your roof shingles, and moss can uplift shingles and increase the risk of leaks. If you have issues with algae or moss on your roof, copper roof strips can help avoid damage.
