"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."

"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 jobs can be expensive due to the required materials and the dangerous nature of the labor. The cost to repair a roof ranges from $390 to $1,920, with an average cost of $1,150, depending on what kind of roof you have and any accessibility concerns. Replacing a roof is much more expensive at $5,890 to $12,800.

Asphalt shingles blister when air gets trapped between building materials, either within the layers of the shingle itself or in adhesives on the undersides of the shingles. As the roof heats up in direct sunlight, the trapped gas expands and creates a bubble in the roof. Eventually, the bubble can pop, leaving an exposed area of decking and underlayment.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

Furring strips (also called wood stripping) are not always necessary for a metal roof installation, but they are highly recommended and may be required by local building codes or the roofing manufacturer's specifications. There are several key reasons to use them:

  • Energy Efficiency: Furring strips, made of wood or metal, create an air gap between the metal panels and the roof deck. This acts as a thermal break, reducing heat transfer into your home and improving overall energy efficiency.

  • Moisture and Condensation Control: The air gap allows for better airflow, which helps prevent moisture buildup and condensation under the metal panels.

  • Structural Support: They provide a solid, even frame to which you can attach the metal roofing panels.

It is especially important to use furring strips when installing a metal roof over existing shingles. Without them, the roof surface can be uneven, and you will experience greater solar heat gain.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.
