A compromised roof on your Hartford-area home can put everything you love at risk, exposing your interior to the elements and paving the way for costly damage. If a storm rolls through town and damages your roof, you need quick, professional service from a trustworthy team. Have years of exposure worn down your roof?
Your roof plays a vital role in protecting your home or business for many years. Whether you need it repaired, replaced, or simply inspected, it's crucial to partner with a reliable roofing contractor that you can count on.

Millstream did a great job on my roof and I would not hesitate to use them again. The crew showed up on time, completed all work as promised, completed all work as scheduled and did a great job cleaning up afterwards. I will recommend Millstream to family and friends and again will not hesitate to use them again.

Dave at Millstream was a pleasure to work with during the review and quoting process. I tend to want to understand all the details and what I’m getting for the cost and he was very thorough and clear with each response. The overall quote was well within that of other local reputable companies I had quotes with and the quality I received looks to be great as there have been no further water issues that were occurring on the previous roof line. The on-site workers were very considerate and efficient to get the job completed very quickly. The project manager, Anthony, was easy to get a hold of and

He was phenomenal to deal with and went above and beyond to ensure we were completely satisfied and happy. He was there every step of the way!! He even plugged up a few mouse holes, showing how caring, and dedicated he is!! We are thankful beyond words for his integrity and dedication! Thank you Eric!! You are awesome!!

Needed a roof to be installed quickly because of leaks. Even with all the rain we had this summer Millstream Construction was able to schedule our roof installation in a timely manner. In a day and a half we had a beautiful new roof. We could not be more satisfied. The roofers did an excellent job and the yard was cleaned of all debris. Everyone at Millstream Construction we communicated with was friendly and courteous. Being personable is why we chose Millstream construction. We would highly recommend Millstream Construction for your next roofing project.

I increased my rating to four stars. Nick Ortiz who is the General Manager at Millstream contacted me after reading my original review from December 2019. He offered to pay for the damages caused to my Gutter Helmet. This was replaced on 1/29/20 at the cost of $300. I am impressed by the customer service to handle this in a timely manner. I will now recommend Millstream to others for roofing projects, but just be aware that they might use subcontractors. I hope the company they use will learn from their past mistakes.

This company did an excellent job on my roof. I bought a special package through Angie's list and paid extra since I needed a rubber roof for a part that was not slanted enough for a regular roof. Even though the estimate I originally got when Millstream came out to give a quote was more than the Angie's List deal (--- and I had forgotten initially that they were coming out because of the Angie's deal), they stuck with the Angie's List package price when I realized that was the source of how I started talking to them. (I was talking with many contractors so didn't mention

Scheduled a 1pm appointment for roof repair with Kevin. He did not show up or call to reschedule. Called Millstream at approx. 3pm and left message inquiring on missed appointment. Did not receive a call back. Surprised as prior rating were 5 stars. Disappointing.

I have had the pleasure of doing business with the Millstream Construction team. Chris Gonsalves, the owner and expert helped me every step of the way. I had a bad roof that was installed by some locals that claimed to be roofers. For the past 2 years it leaked from faulty workmanship and together, we uncovered the many problems, figured what needed to be done (replace the shingles, underlayment, etc..) and a couple months ago, Chris and his team took care of the problems and now, I have a new roof with a "Platinum Warranty".
It really does matter who you hire to work on your house

The ONE call you need to make for all your roofing needs, Millstream Construction did a complete roof replacement on my 5300sf home recently. The job was completed in under 48 hours, start to finish, and we were exceptionally satisfied.

Honestly, I was blown away. Damien showed up and was able to make a repair right on the stop. I wasn't expected the quick turn around, professional attitude, and positivity. I am grateful we connected to them!
Any future home repairs are going through Millstream. Couldn't be any more impressed.
