“Professional Roofing Company did a fantastic job on our roof! The crew was incredibly hard working and pleasant. We couldn't believe they replaced the entire roof on our home & two car garage, installed 4 sky lights AND did an impeccable job cleaning up all in ONE DAY. Highly recommend!”

“I just replaced a roof on my personal home and the work was done by Jon Kenyon and hands-down it was the best experience I’ve had to-date. Jon is an experienced contractor who actually runs his business like a business, they did what they said they were going to do in the timeframe they said they were going to do it and kept us updated with a high level of communication that you don’t typically see in this industry. To top it all off the projects was on budget! I don’t usually take the time to write reviews but my experience was truly that great.”

“They were extremely professional and did an awesome job from start to finish. They arrived at 7:30 this morning and we're gone before 3pm. They took great care in encapsulating our home so as not to damage my flower gardens or our siding. As part of their final cleanup they go around the home with a magnet roller to get any nails that may have been missed on the tarps.(something I've never seen before)
I would highly recommend Professional Roofing Company. Jon Kenyon and his Crew were phenomenal!!”

“Jon and his team came and provided quality installation and service when we needed it most. When you need a new roof you don't have the luxury of time and his team came out in the winter on a 2.5 story colonial in Nottingham and accomplished the task in a day with sunlight to spare. Don't bother calling anyone else call Jon.”

"Jon, Brittany, all of the staff and roofing crew at Professional Roofing Company made the job on our house a breeze from beginning to end. Jon came out and looked at our roof, took measurements, climbed on the roof to address concerns we had about our skylights, etc... After deciding to go with his company, which was a no brainer, they were very accommodating in getting us on their schedule. The crew itself was totally skilled and professional. You would have never known they were here except we ended up with a beautiful new roof with top of the line GAF shingles and an amazing 50 year shingle warranty/10 year workmanship warranty and all at a very fair price! I highly recommend you give Professional Roofing a call."

“From the first meeting (where there was no pressure) to the final installation, everything was handled with precision, timeliness and quality. The roofers were on time, polite and respectful. They worked tirelessly. The whole experience from start to finish was delightful, easy and flawless. The clean up during and after the project was top notch. Everything was left clean and no nails, staples or shingles left behind. I’m super impressed and happy to have this job completed.”

“I cannot say enough nice things about Jon and his company. He was very informative without being pushy, and he patiently answered all of my many questions. He explained everything to me and my options. He was my top choice out of 4 estimates. I knew I wanted him to do the job largely because he treated me as a person rather than another job. He worked with me and my budget to replace my roof on my house and we even included my shed! The result is really beautiful! And I have peace of mind knowing that it was done right by a great company and done with quality materials. Thank you so much!”

"We've had some serious storms in North Berwick since I had my new roof done last fall but I didn't have to worry a bit. Professional Roofing Company was a joy to work with - Jon and his crew did what they said they would when they said it would be done. Communication was excellent and the work was top quality. They went the extra mile by trimming branches above the roof and doing a great job cleaning up. I heartily recommend them."
