"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

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

The lifespan of an impact-resistant roof averages 30 to 50 years, depending on the quality of the shingles and the amount of wear and tear it endures. Some high-quality shingles may last even longer. For comparison, a standard asphalt roof lasts about 20 years, so choosing an impact-resistant option can increase your roof's lifespan by 50% or more, particularly in regions prone to extreme weather.

Yes, a new roof will add value to your home, often providing a return on investment (ROI) of between 60% and 70%. Not only will a new roof boost curb appeal, but savvy homebuyers will also know that a new roof means they won’t have to worry about roof leaks and related damage for years after closing. They’ll also know that they’ll save money by potentially having decades before they need to worry about paying for repairs or replacement.

Re-roofing is the process of placing a layer of shingles over top of existing shingles, rather than pulling out those shingles and replacing them. Compared to a full roof replacement, re-roofing typically costs less and requires less labor and time. It's not an option for everyone, though. You may need a full roof replacement if your roof already has more than one layer of shingles. A full replacement may also be necessary if your roof has extensive damage.

The four types of roof sheathing are plywood, oriented strand board (OSB), planks, and tone-and-groove boards. The overwhelming majority of homes use the first two (especially OSB) and the other two are not often seen outside of special use cases. Methods of sheathing include solid sheathing, open sheathing where there are gaps, and plank sheathing. Most roofs are solid sheathing.
