"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."

"Got quotes and talked to 3 other roofers. 3rd Generation Roofing gave me the best pricing, great costomer service and followup, and their crew was efficient and clean. I would, and already have, recommended 3rd Generation Roofing to others in need of a new roof. Altogether a good project experience."

"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

Maybe you waited a little longer than you should have before dealing with the snow accumulation on your roof, and now you are wondering if there is risk of roof collapse. Here are some signs you should look out for: a sagging roof, cracking and cracking sounds, cracks in walls, and leaks in your attic and ceiling.

If you suspect potential roof collapse, do not delay. Take immediate action. Call a professional roofing company and get an inspection. You may want to move your belongings to a safe place and relocate your family until everything has been taken care of.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.

A roof's lifespan can range from 15 to 200 years, with an average of 25 to 50 years, depending heavily on the material, quality of installation, maintenance, and local climate. Asphalt shingle roofs are common and typically last 15 to 30 years; three-tab shingles have a lifespan of about 20 years, while architectural shingles can last up to 30. More durable materials have longer lifespans: metal roofs last 30 to 100 years, clay and concrete can last 50 to 100 years, and slate roofs can last up to 200 years with proper care. Regular maintenance, such as cleaning gutters and replacing damaged shingles, is crucial for extending the life of any roof.

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

To cap off a chimney flue, start by measuring its width, length, and diameter, if it’s circular. Purchase a cap that fits the flue, and decide whether you want a temporary or permanent model. Then, slide or insert the cap onto the flue and secure it with a screwdriver. Be sure to avoid over-tightening the screws to prevent chimney damage.
