"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

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

Condensation can occur on the inside of a roof, but it should always be temporary. It does not necessarily mean there is a roof leak. Condensation happens when the inside and outside of a house are at different temperatures. For instance, if it is hot during the day and then gets very cold at night, the inside of the house will be warmer than the outside and may cause condensation to form on the inside of the attic. This may not be cause for concern, but if it is happening frequently, it should be addressed; otherwise, it could cause roof leaks, compromise the structural integrity of the wood, or allow mold to grow.

The easiest type of roof to build is a shed-style or lean-to roof, which features a single sloping plane from one side of the building to the other. Unlike a gable roof with two sides meeting in the middle, a shed roof's single slope makes the construction process more straightforward. The rafters are typically single pieces of wood that span the distance, often without the need for additional supports.
