"We hired Wells Roofing for roofing repairs from storm damage. They went out of their way to ensure that the job was completed to the high level of quality they expect and the result was above my expectations. Great work and the job came in slightly under bid, which was greatly appreciated. I will definitely be looking to hire them for future roofing needs and would highly recommend them should you need roofing repairs."

"We had a great experience with H&F on our roofing job. Jill communicated with us regularly throughout the entire process and she always responded quickly when we had questions. I watched the crew install the new roof, and they obviously knew what they were doing. H&F did an outstanding job for us."

Roofing FAQs, answered by experts

You can negotiate roofing payment terms with a contractor, but if you’re working with a reliable, trustworthy roofing contractor, the quote they gave you is probably fair. It’s often not worth haggling over the cost of the job unless you feel it is particularly unfair. If you do, get quotes from other roofing companies to compare prices.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

A new roof may improve insulation and ventilation problems that can lead to ice dams, but it’s not a solution for preventing them. All roofs are susceptible to the conditions that cause ice dams, so it’s best to invest your money into insulation and gutter management solutions rather than a new roof if you don’t need a replacement yet.

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.
