I called Dennis General Contractor after identifying missing shingles on my roof. Within two days, Forest came out and not only evaluated my roof - he fixed it! He had a full schedule but managed to fit me in before the snow fell. I am incredibly grateful! He was amazing to work with - so responsive, detailed, and very reasonable prices!  highly recommend him and his company!

Offers free inspections with a roof report that highlights areas of concern. The inspector let me know I had life left in my roof when the other companies were trying to convince me to replace it right away. I appreciated her honesty and look forward to having it replaced with this company.

The whole experience from start to finish was incredible. I had called several outfits and only half even bothered to return my call. These guys came right out and discussed my options in plain, non high pressure fashion. It was a roof replacement for my pet boarding business so was important they be able to work around my schedule.
The crew was fantastic. So courteous, professional, clean and FAST! I expected to have a bit of cleanup to do after they left but they were so thorough.
The best part was dealing with Jasmyn. You are an absolute gem and I appreciate you greatly!

Dennis General Contractor replaced our roof shingles and did a fantastic job. The workmanship is of high quality and the crews were very skilled and professional. Because of an upcoming real estate transaction there was some urgency to the job, and they started and finished the work in a very timely manner. The quote for the work was detailed, accurate, and very reasonable. Their online portal system made contract signing and payment easy and provided transparency throughout the process. I highly recommend Dennis General Contractor for any roofing or other construction needs you might have.

After battling a leaking garage roof for years (!), I finally had it replaced by Dennis General Contractors. From start to finish, the team courteous, proactive, and professional. They are competitively priced and the service is off the charts. The crew had my roof done in less than three days and it makes my house look brand new. Now, I find myself still peeking into my garage on rainy days and being stoked that there are no waterfalls or puddles.
