"All Under One Roof did an amazing job with my roof replacement. My roof was leaking for the last couple months so I decided before winter to replace. When they were replacing it I was informed and shown pictures of how bad the damage was. The roof has extensive rot in many areas. All Under went above and beyond and cut out all the old rot and replaced. They went into great detail to show me the rot and how it was leaking for years, but not into the interior of the house. I am so happy at how it came out and will recommend All Under One Roof to all my friends."

"This is not the review I did 4 seconds after they finished the job - this is the review 16 months after the job. Years ago, we had our windows done. Mind you, their salespeople are extraordinarily assertive, personable and charming - and rightfully so, as they will spend hours and hours in your home making and finalizing the sale, as well as closing out your project. The problem is, they talk super proudly about their lifetime transferable warranty - which "covers absolutely everything! No matter what! You can take a razor blade to the screens just because you feel like it and they will be replaced, no questions asked!" This...is not true. The warranty is like all other warranties - subject to defects and defective installation only. No coverage for wear and tear, issues due to neglect/accidents, acts of god or anything related to weather or the elements. In fact, even if you paint over it or have work done by outside companies that affect the product in any way, the warranty could be voided. It was ABSOLUTELY sold to us as though NOTHING was out of bounds as far as repair/replacement was concerned. Shame on us for not going through all the warranty info with a fine-toothed comb, but the pep rallies by the salesmen we had ( one sold us windows, the other siding/gutters/trim) really get you excited. You love these guys and totally trust them for their enthusiasm and knowledge. You would not believe how much they push that their warranty covers EVERYTHING - FOREVER! So either these guys are trained to tell us something other than the truth and don't read the warranties themselves, or they lie for the sale and keep you in their pockets until the project is over, when you never hear from them again. Any issues we called about AFTER they physically left our property, were ignored or put off until forever - such as debris from work left for over a month on our front lawn, or nails that we were promised would be picked up thoroughly using a metal detector so our child wouldn't puncture his little feet (made them come back twice and they still did a pretty terrible job - are those nails even magnetic???), or the shutters they were supposed to change out for us. The quality of the materials is extremely high. The quality of the work done was high. The customer service, when all is going great, is awesome. Once you have a complaint though, they are nearly unreachable. They don't want to hear it. You can contact customer service, but they will just leave a message with the PM (if he didn't call me back when I called him, why would he when cust. serv. reps from Wherever, USA tell him to?). Nothing but the product quality separates them from anyone else, so weigh your options. Power is NOT cheap. Bottom line - OK company, great salespeople (personality- and effectiveness-wise) and products, poor customer complaint resolution, fair cleanup (looked great, but super unhappy about finding HUNDREDS of nails in our lawn), average lifetime warranty. I put that I would hire again because YES & NO are the only options. I chose YES because I know more now and I do think they sell superior products and there are loyalty discounts. If UNDECIDED were an option I'd have chosen it. As long as everything goes great, you'll be happy. If not, best of luck to you."

"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"

"ReRevive Roofing and siding LLC did a skylight installation and a cap repair on my townhouse in bedford. They arrived on time, worked efficiently, and left the site clean. The skylight looks great and the cap repair has prevented any further leaks. I'm very satisfied with their work and would recommend them to anyone in need of roofing or siding services."

"I would trust OTB Remodeling with any job. They were a fount of information during the process and seemed genuinely interested in me getting my needs met over making a sale or getting me into work I didn't need. They were honest and straight forward. I will definitely be using them the next time a potential job comes up. "

"It went incredibly well. I woke up one morning to a leak in my roof. I knew the roof was going to need to be replaced at some point, but I was hoping I'd get another year out of it. The roof was in bad shape when I bought the house. I immediately started calling all of the roofing companies I could find on Google. It was early so I was leaving voicemails. Kasey from James and Whitney was the first and only one to get back to me in a timely manner. He was incredibly helpful on the phone, walking me through how to put a tarp over the impacted area. He even swung by later THAT DAY to check and make sure it was installed properly and to assess the roof. I knew it needed to be replaced so we went right into talking about estimates. The estimate was within my budget but the new roof came with a FIFTY-YEAR WARRANTY for parts and labor. You just can't beat that kind of warranty on an asphalt roof. We were scheduled within a week and I had a brand new, perfectly installed roof within a month. Kasey and his team were super respectful during the installation. When the installation had finished, Kasey inspected every inch of my property to pick up any tiny bits of trash and leave our lawn spotless. The whole process was so easy and stress-free. 10/10 would recommend!"

FAQs for flat, foam, or single ply roofing installation and replacement projects in Greenland, NH

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
