"JPCarroll did a fabulous job on replacing my complicated, decrepit Victorian roof, completing it in a timely way and against adversity – they did the whole thing in the month of January in freezing temperatures and sometimes snow and ice. I interviewed five other roofers. However, their sales person took more time and provided far more specificity than any of the other others. Their bid was not the cheapest but turned out to be the best value by far. They went the extra mile to resolve many unforeseen problems, and the quality of work was high. Everyone I dealt with, owners, staff, and laborers, were courteous and responsive throughout. The job supervisor, Kevin, was thoughtful and included me on numerous decisions. Luke Carroll, production coordinator for the job, was always available to help, as was everyone else, even on weekends. They coordinated well with my carpenter, replacing a significant amount of trim, siding, and more as a team. The people doing the actual labor worked"

"It was a very smooth process from the beginning to the end. The sales person helped us find a bank to finance. The work was timely (in spite of the snow), and they picked up after the work was done."

Roofing questions, answered by experts

Costs vary by repair scope, materials needed, and labor, with average repairs ranging from $300 to $1,000, contingent on roof size.

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

TPO roofing can last anywhere from 15 to 30 years, or an average of 22 years, but you can extend its life expectancy through proper roof maintenance. For the best chance at realizing the longest life span possible, keep tree branches trimmed so they’re not in contact with the roofing material. Inspect your roof regularly and repair any damage immediately.

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.

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.
