"John came in today on a holiday day to check my roof. He is a very honest man. He told me my roof is still good for another two years, and doesn’t need any repairs at this time. I highly recommend him for any roofing projects. Thank you John!"

"We are extremely happy with our new roof. The crew manager Jeremy was diligent about how things were going and done. He answered any and all questions we had. His crew worked extremely hard in extreme heat. We don’t have any trees near our roof so they were in the sun all day. They never slowed down they kept a steady pace. They were at our home 2 days, they worked cash a team to complete the job and the clean up was done with precision each day. People going by we’re impressed with the professionalism of your company and of an amazing job. One of our neighbors is interested in your company doing his roof. We would highly recommend your company. Our new roof makes our house stand out in the neighborhood. Thank you Jeremy and Crew"

"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"

"Three weeks ago I decided to replace my 30 year old. I Googled roofing contractors and happened upon Scottâ s Roofing . I started reading their reviews and they were all five star and very complimentary. I called and talked to Sean Nadeau, one of the principals in the company.and he promptly sent a detailed proposal including the workmanâ s Compensation & General Liability insurance certificates. I then called and spoke to Darby Sullivan, office manager and she was very patient while we finalized the contract. Scott â s Roofing arrived on time, stripped and replaced the roof in the most professional way. Kevin, an on-site supervisor was present. Sean also arrived mid morning to check on the progress. The crew worked very hard and I could not have been more pleased with the outcome of the roof installation. I would like to thank Sean, Darby, Kevin & the crew for all of their hard work and attention to detail. This review, like all of the other reviews, merits the five star rating. Use â Scottâ s Roofing â and you will not be disappointed. Henry J. Pagliarulo"

Roofing questions, answered by experts

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

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.

Yes, hail damage to your roof can definitely cause water leaks in your roof. This is because hailstones can break, chip, crack, or split shingles of all types, exposing underlayment. This underlayment doesn’t offer as much protection against water, so when it becomes compromised, water can penetrate and leak deeper into your home.

Chimney caps may be installed by a few different professionals, including a chimney sweep or a mason that specializes in fireplaces and chimneys. A gas fireplace technician is the best person to install a chimney cap on a gas log fireplace vent to be sure the cap is appropriate for the application.

DIY is not recommended, as slate requires specialized handling and proper underlayment installation for durability.
