"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"

"Chris and Aaron worked with us to help figure out where the mildew smell was coming from. We just bought a house and the back bedroom smelled awful. They replied to our request for an estimate ASAP. We couldn't be happier with the service I received from them! We had some damaged siding and a leaky window that needed immediate attention. They responded quickly, assessed the situation thoroughly, and provided a clear, affordable estimate. Being a local company, they were able to schedule the repairs much faster than other companies I contacted. The work itself was top-notch; the siding looks seamless, and the window is now perfectly sealed. What truly impressed me was their trustworthiness. They were honest about the necessary repairs, didn't try to up-sell anything, and kept me informed throughout the entire process. If you're looking for a reliable, affordable, and talented siding company, we highly recommend them!"

"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

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.

Look for certified local roofing contractors with plenty of experience working with cedar. There are also several important roofing questions to ask before choosing a roofer, including whether they are licensed, bonded, and insured. Once you’ve rounded up a few good candidates, compare estimates and hire whoever gives you the best bang for your buck.

The most crucial roof-strengthening method is achievable by following proper construction methods and guidelines from the start. To strengthen an existing roof, framers and DIYers can add hurricane ties or straps to the structure, sister rafters and other framing or truss members, or install additional fasteners or adhesives where necessary.

A roof can collapse from a leak if the leak is left unattended long enough. A collapse will happen when the structural components of your roof become saturated with water over time. The roof deck or rafters can slowly weaken until they can no longer support the weight of your roof.

Though roof coatings can last up to two decades, it’s a good idea to recoat your roof every four to six years. This is especially important if you have a built-up roof, which is vulnerable to moisture issues. Inspect your built-up roofs annually to make sure they don’t need a new coat.
