"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"

"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."

"Excellent team and communication for our roof project. We needed someone to repair our roof that has shingles thats been needing repair and they were able to deliver and spring into action within a day ! It was perfect as the rains were coming and the damage to our roof would have gotten worse. From the time I first communicated they were able to arrive and give us an estimate and work with our insurance company (which was not easy) in the same day. Highly recommend this company ! Thank you"

"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 felt is the most common type of roof underlayment, likely because it has been around the longest. It’s called roofing felt because it is often made of felt soaked in asphalt. Depending on the type of roofing a home has, roofing felt comes in different thicknesses. 

If properly installed and maintained, roofing felt should last between 10 and 25 years. 

You can replace a roof in the winter, though it’s not the most popular time to do so. The biggest drawback of winter roofing work is the weather. Snow and ice make for dangerous, slippery working conditions. Plus, shingles can only be installed in temperatures above 40 to 45 degrees. 

The best time to replace a roof is in the spring or fall when the weather is mild. However, you can likely save some money by booking the job in the winter off-season, when roofers have more availability. 

A roof replacement will usually include removal of your old roof, shingle replacement, and a new roof underlayment, but it may only include adding new shingles if you’re layering new shingles over the old shingles. If you have signs of roof leaks or your roofer finds water damage to the roof decking underneath your old roof, it can also include replacement of the OSB or plywood decking that lays over your rafters and supports the roofing material above.

Copper roofing works well in all kinds of climates, but it’s ideal in humid climates because it naturally repels fungus, moss, and algae. This makes it one of the best roofing options for Cape Cod homes in the Northeast, as well as homes in the humid southern states and snowy northern states. That said, copper is vulnerable to thermal expansion. If you live in a climate that has extreme temperature changes, your contractor will need to consider this during the installation process.

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.
