I recently had our 20 year old roof replaced that had a couple minor water leaks. I saw the many positive reviews for the company online so I gave them a call. They had someone come out and inspect my roof within 2 days. A video was taken of all the problem areas my roof had. My roof was in pretty bad condition and I didn’t realize it until the representative showed me everything. Guaranteed Roofing was the first company I called and the one I decided on to have my roof replaced. I didn’t bother calling any other contractor because the representative (James) was extremely professional and knowledgeable of the shingles and roofing materials. The shingles are warrantied for 40 years by the manufacturer and the workmanship is guaranteed for 10 years. I explained that I might be going solar on the south side of our roof. James made sure that the ice and water protection (extra shielding) was added more than usual to the south side of the roof for better protection for the roof under the solar panels. The price might have been a little more expensive than others but the quality was top notch. The crew showed up 10 minutes early. They started the job on the dot and finished by 1pm the same day. Lightning fast! The supervisor of our job answered all my questions and was extremely professional. He is also a veteran and he spoke highly of how the company treats him. I was very happy to hear that as I have many family members past and present who are veterans. It happened to come up in general conversation we had. The crew cleaned up beautifully. After they were finished, I couldn’t even tell that anything had happened on the property that day. Absolutely meticulous! After I had signed the contract, I realized they had a deal going on through their website for a discount off the project cost. Jennifer was very helpful in actually adding on the discount even though the contract was already signed. That is amazing customer service and saved me money. Overall I rate Guaranteed Roofing above a 10 out of 10 which Google won’t let me do unfortunately. I will recommend them to anyone I know that needs roofing done!

Guaranteed Roofing was great from the start. Everyone I dealt with was professional and courteous. They did everything they said they would and so quickly! They cleaned the yard up very well! The workers were very good and they worked on such a cold windy day! Amazing! The best part - I love my new roof! I would, without hesitation, highly recommend Guaranteed Roofing!

We had our entire roof and all gutters replaced by Guaranteed Roofing. From initial contact to final cleanup, it was a great experience. Excellent communication throughout the process.

I found James Bryson extremely knowledgeable, very responsive, helpful and honest. Went out of his way to help me with insurance (wind damage), samples & scheduling prior to winter. Production team gave timely notice & instructions for installation. Installation was done in 1-2 days for 2 unit townhouse. Moved necessary outdoor items & cleaned up, won't know there was a major installation done. I would use them again.Thank you to your team of experts.Gail, Woodstock Valley CT

There's a lot of stress that goes into big home projects, like getting a new roof. It's a major element in protecting my biggest investment - my home. The good folks at Guaranteed Roofing made it as stress-free as possible! From beginning to end, they were professional, on budget and on time. They took time to answer all my questions, responded quickly to my calls and cleaned up the property as if they were never there. Quality work, good people. If you're looking for a reliable, professional roofer - I highly recommend Guaranteed Roofing!

I recently used them for a replacement window project on my son's newly purchased 1800's home. From start to finish, this company exceeded all expectations. James Bryson was extremely knowledgeable and helpful in the estimating process. 'Red', the PM was second to none. Working on a house this old is always a challenge and his level of detail and precision was top notch. I would recommend, without hesitation, Guaranteed Roofing. In fact, I just hired them to do work at my house!

I used Guaranteed Roofing to replace my roof in North Franklin. They helped me through the insurance claim process and replaced the roof of my home and outbuildings in two days. They were professional, timely, and responsive. They answered all of my questions, and left my yard so clean that you would not know that I just had the roof replaced. I would use them again for other home improvements or repairs.

Seven months ago in November 2020 a large tree fell on my house during a heavy rain/wind storm knocking out my bedroom window in the process. With the pandemic and the terrible spread of Covid I didn't know when JPW Building LLC - Guaranteed Roofing would be able to start repair. The insurance company took forever to estimate damages, and changed details and only wanted to repair a few things NOT bring it back to its original shape. I was stressed to the max! Once the estimates and repair amounts were finally in concrete JPW went right to work. Instead of part of the roof being repaired, they repaired and replaced the whole roof. The insurance company only wanted to partially repair the siding damage leaving part as aluminum siding and the remainder as vinyl siding. JPW got the whole job done so that everything matched. The gutters were all replaced. Several lightening fixtures were replaced. It took 8 months for the house to finally be done. But JPW completed all the work, once started, beginning of June until the final payment was made on July 15. (House resided, roof redone, window replaced, light fixtures replaced and gutters replaced) . And they did an excellent job. This 74 year old lady, former Volunteer Firefighter, widow to a Vietnam Veteran and Grandmother to many, is very happy and relieved now. Thanks JPW!

The young man who came to my house was personable, polite, knowledgeable and attentive. The work crew was prompt and worked tirelessly. At the end of the day I had a new roof. I’m pleased with the look and more importantly it is watertight. Even Elsa made no impact. I recommend this company and would used them again.

JPW Building, LLC recently completed a project on my home that included the installation of siding, facia/soffit/trim, storm door and a new porch light. The project was completed with outstanding workmanship and professionalism. My home is an older one that required creativity and expertise to complete the project. Every challenge was met with a skillful solution and a most positive attitude. Jeff, the owner, was available to consult with his team, and me personally, through every phase of the project and every member of the team took the time to assure that I was pleased with the outcome.It was a pleasure working with a company that takes great pride in their work! I couldn't be more pleased with the amazing transformation of "this old house"! This company is a class act; highly recommended.

Guaranteed Roofing helped us to manage this complicated project and we are very pleased with the final result! Highly recommended and would definitely work with them again.

Guaranteed Roofing will meet or exceed your expectations. I have met and worked with a lot of contractors. Guaranteed Roofing is by far the most trustworthy, honest, and reliable contractor I have come in contact with. The bid is accurate, the crew shows up for work when they state, and they are thorough. Follow up is unheard of with most contractors. Not the case with GR. It is evident they want life long customers. Jeff and his crew are very professional, listen to any concerns or questions you may have, and address them. Whatever your building need, JPW and their roofing division is where you need to go. You will not be disappointed.

Penny and I were very pleased with the work and professionalism of Guaranteed Roofing. Jeff and Mike made us feel very comfortable during the completion of our new roof. They were always available to answer any questions and concerns that came up during the project. The crew was very hard working and cleaned up our yard nightly. We would certainly recommend them to our friends in need of a new roof.
