"Long Roofing went above and beyond when installing our roof and gutter. The job turned out more difficult than we thought it would be but Long Roofing made me feel comfortable and reassured that they would fix everything. Everyone involved from the salesperson to customer service listened to our needs and treated me with respect. The roof looks amazing. I don't want to get into price, but even though you may get someone less expensive, using Log Roofing was well worth a little extra cost"

"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"

"We could not be happier with our new metal roof! Customer service was beyond reproach and the company's CEO called at the end to ensure we were satisfied with the finished product. We went with the 26 gauge corrugated roof - outstanding product and the installers were able to flawlessly install the panels on a difficult roof (pitch and bump-outs). I, without reservations, recommend Maine Metal Roofing."

Roofing questions, answered by experts

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

The best type of roof vent depends on the size, type, and construction of your roof as well as the environmental conditions in and around your home. In many cases, an active ventilation system that draws in fresh air and exhausts air out through the attic is the most effective. Active ventilation systems include roof ridge vents with baffles, turbine vents, and soffit vents that are used together with another type of vent.

Cool roofs last for roughly 15 to 30 years. You can install a cool roof coating over an existing roof, but keep in mind that this might not be worth it if your roof is near the end of its life expectancy. If your roof isn’t near the end of its life, adding a cool roof coating can make your existing roof more energy-efficient and help it last longer, so you’ll have to weigh the pros and cons.

The proper specifications for furring strips can vary, so you should always consult the roofing manufacturer's guidelines or your roofer. However, general recommendations are as follows:

  • Thickness: Furring strips are typically 1 to 1-1/2 inches thick, meaning standard 1-by or 2-by lumber works well. In areas with extreme winds, a thinner strip may be preferred to limit how much air can get under the roof and cause uplift. A thicker strip can add slightly more insulation but will also increase installation costs.

  • Spacing: The recommended spacing for furring strips is between 12 and 24 inches apart on center. Proper spacing is crucial for ensuring good airflow, adequate drainage, noise reduction, and better energy efficiency. The ideal spacing can depend on the roof's pitch and the specific type of metal roofing being installed.

DIY is not recommended, as slate requires specialized handling and proper underlayment installation for durability.
