"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

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

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.

EPDM roofs have a few common problems, most of which can be resolved with regular maintenance. This type of roofing is laid down in sheets with seams, which can be a starting point for leaks. Proper installation and roof sealing can often avoid seam issues. 

The material is also susceptible to tears and punctures from falling branches or other sharp objects. There are black and white versions of EPDM, and the black version is more prone to fade and succumb to UV damage. Regular roof inspections can protect the costs of rubber roof installation and extend the life of your roof.

Asphalt shingles, wooden shakes, and slate or clay roofing tiles are often replaceable without having to replace the entire roof. It's possible to replace just a few shingles or tiles without much trouble in the case of wind damage or other minor problems. DIYers can perform the task in some situations. However, professional repair is always the best bet when it comes to roofing.

You should hire a roofing professional to install a metal roof, as it’s an essential part of your home and a difficult installation. Your roof provides the most protection for your home among all of the building materials, and any mistakes made during the installation process can quickly lead to roof leaks, water damage, and significant repair costs. A roofing professional will ensure your new roof is installed properly and according to building code to minimize that risk, and they will usually back the installation and materials with a roof warranty for added peace of mind.
