"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"

"I knew from the start I wanted a metal roof and that I wanted the Permalock product for its quality and durability, and that it looked like the shingle roof we had. The lifetime guarantee and product sold me. The roofers were great, and every night the place was cleaned up, very efficient company."

"Dylan was responsive, fast, courteous and professional. He came out quickly to perform a no cost estimate for the roof cleaning job. I had a lot of moss growing on the roof. He provided me with a reasonable price and was able to perform the work the next day. He communicated throughout and provided a sketch of the roof and itemized the work to be performed. Most importantly, Dylan showed up as promised did the work and cleaned up. I was very impressed with his work ethic and commitment. I will definitely hire The Roofing Co. NH again."

"These roofers worked hard to replace my old flat roof which was directly under a deck. They were carefully not to damage the decking so we could reuse it. The only issue I had, I noticed dozens of cigarette butts all over my road (20 actually). I talked to the boss and hopefully this never happens at another job site. How a worker thought this is ok, I don't know."

"I'm a return customer. They did our replacement windows a few years ago, and they just replaced our asphalt roofing shingles. They did a wonderful job. I was amazed and impressed with how quickly, and how well, they completed the job. I love my new roof."

Roofing questions, answered by experts

Roofing material costs vary depending on the type of material you choose and whether you install it yourself or hire a roofer. Shingles are the most affordable option and cost between $70 and $400 per square, metal roofing is between $100 and $1,500 per square, and concrete tile is between $300 and $1,000 per square.

A roof overlay will last an average of 15 years, compared to the 20 to 30 years or more that a full roof replacement for a shingle roof will last. An overlay’s lifespan may be shortened even further if there’s underlying damage to the existing roof or structural problems with the roof supports.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

Depending on the type of damage your roof shingles have, you may be able to simply repair them without having to replace them. However, if there are more than a few to repair, replacement is likely the easier option. You may only need to replace a few of them. Repair shingles by applying roofing sealant directly under the shingle's damage and then directly over it. 

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.
