Very large roof with steep incline. Roofers on harness, fast, professional and great clean up. Had to replace 37 sheets of plywood for some of the smaller roof sections, but completed in a timely manner.

James Bryson came to my home & gave me an honest, accurate, and thorough evaluation of my main roof and my detached garage roof. He was punctual, courteous, and professional. His work ethic and quality of work were impeccable. I highly recommend Guaranteed Roofing and James in particular.

I did my homework and found JPW Building (Guaranteed Roofing) in Canterbury. They are a member of the BBB and local. Tom Thompson was professional and friendly to work with on my roofing project.The workers were showed up on time under supervision and didn’t stop till the roof was completed.They did a great job of cleaning up and leaving no trash or nails (a must for me)I plan on using JPW for another project in the Spring.

They were professional, clean and the quality was outstanding. The roof color made a huge difference in the look of the house. The new gutters will help keep my basement dry. Overall, I am very pleased with Guaranteed Roofing!

My husband and I hired Guaranteed Roofing because they had previously done work on our property, replacing our front and back stairs. Pleased with their reliable business manner and impeccable work, we decided to hire the company to replace our deck. We are extremely satisfied with the quality of the product and the professional workmanship that went into the deck. The master builder kept us informed on what he was doing and made sure our questions and concerns were promptly addressed. The job was completed in a timely manner and the site was left in a pristine condition. We would recommend Guaranteed Roofing for any future home repairs.

I had two windows on my second floor that needed replacing which they did. The job on the replacing was excellently done. They ran into a couple of small problems which he was able to take care quickly. They only thing that held me back from a complete 5 star review was it took 4 months from the signing of the contract to the installation. The lead time of the windows themselves was crazy long. I will definately be replacing more windows.

First I spoke with Tom who sold me immediately. He showed up when he said he would and was extremely knowledgeable. Most important to us he seemed very straightforward and honest. Received a written quote very quickly. Permit was handled by this company. Workers also showed up on schedule and finished quality work very quickly. I told Tom the test will be when it rains. Well we just had downpours and we're dry. Recommend Guaranteed Roofing very highly.

Guaranteed Roofing was great from beginning to end. Jennifer is an A+ customer service rep. Inspection and estimate were well done and easy to understand, and Sean was great about answering my questions. Installation was only two days and well done. Highly recommend!

James was extremely helpful and explained every detail of the project when he quoted our new roof. Due to some communication issues (possibly on my part) we had the wrong month on our schedule for the new roof. When they showed up a month earlier than we had expected, they we very helpful in clearing up the issue. Luckily we were ok to have them do the roof when the showed up. The project supervisor Norm was very professional and had a positive attitude. He was quick to communicate each time they found hidden damages and providing us with the updated costs to fix them. When they left everything was cleaned up well the new roof looks great.

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. Strong technical knowledge of roofing and gutter systems. High quality work throughout. On time and highly professional. I highly recommend GR for your next roofing and gutter project.

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!
