"All Under One Roof recently replaced my roof on a 3-story, 200+ year old Federal in Newburyport. It was a big job that entailed removing 3 layers of rolled roofing/asphalt shingles; removing original skylight & taking down old dormant chimney to roof line and roofing over both; installing ½ “ plywood and asphalt shingles over new roof. I can’t say enough good things about All Under One Roof. They had a great crew and did a fantastic job. In fact, my neighbor across the street who had a birds eye view of work in progress, then hired them to replace his roof. John Lanzafame, the company’s owner, is a jewel. He’s very professional, responsible and communicative – a “take charge” guy in the best meaning possible. I was completely comfortable and confident that I was in good hands, and did not have to worry about micro managing the work. I should also point out that All Under One Roof began work on date scheduled (a month in advance) and completed the job (start to finish) in short order. I highly recommend All Under One Roof. Have dealt with various contractors for numerous issues over the years as I own several rental properties, and this has been my most positive experience by far. Kathy Quill"

"I had a leak that can be seen from a ceiling. Called several roofing companies and got no reply back. Used home advisor and have Andrea called me and scheduled the visit promptly for Freddy to come and check the leak. Freddy was very professional, identified the leak that was due to improper seal of one of the skylights and fixed it right away. He also checked my other skylights and some had the same problem which he fixed. Freddy checked my roof for issues and provided tips for maintenance so it can last long. Definitely will recommend Global Home Improvement, Inc as a honest and very professional company !"

"Leo and Ricardo showed up to look at the job on time and they were very professional. They evaluated all the troubled spots and took pictures. They provided a comprehensive quote within a day or two complete with the photos they had taken. I had a few questions on the quote which May in the office tried to answer. Once she was unable to answer some of these questions she had Leo and Ricardo call me. May is very easy to get in touch with but Leo and Ricardo are a little more difficult to reach since they are out in the field all day. Once I approved the quote the were at the house the next day to erect scaffolding. They also were expecting a deposit from me which was never made clear so there was a little confusion there. Our house was built in 1884 so after they started work they discovered the roof was in worse shape then they originally anticipated. They were quick to send photos of the condition of the roof but I was never given a firm price as to what the additional costs would be. They completed work in 3-4 days and clean up was done professionally. The additional work they needed to do was significant and I was never fully made aware of what this was until I received the final bill. I trusted Farina that the price Farina billed me on the additional work was fair. This is based on the other quotes I received from other roofers-all of which seemed either too simplistic of a fix or far too comprehensive and expensive considering the size of the leaks."

"Communication was good. We had to coordinate with removal of solar panels. We were held up a little bit waiting for a building permit but once that was resolved the install was scheduled a few days later. The crew of 7 arrived at 7 AM and worked non-stop until 6 PM. Completing the entire roofing job from removing the old shingles, replacing some wood and installing the new shingles. They cleaned up the entire work area once done. I would highly recommend them for any roofing jobs you might have."

"Very easy to get in touch with! Whenever I had a question for Chad, he was always an easy text or call away. The quality of the work is good, and the price was about $100 less than comparable quotes I received from contractors using the same roofing system."

Roofing FAQs, answered by experts

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.

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.

Building an A-frame roof falls under the category of constructing a steep roof. While its structure is relatively simple, its height and requirements for more materials than a shallow roof design can increase its cost significantly. Expect prices for building an A-frame roof to hover around average to slightly above average.
