Al was a straight shooter and laid out the work to be done so I understood everything about how the install was going to take place.
One small flashing point was missed after install but the crew was on it asap and corrected that without fuss. Again Al was on the job to make sure I was a happy customer.
Roof and gutter crews were fast and efficient, and did a fantastic job on our house. They came highly recommended by my father as well, so I knew I was getting the job done by a good company but they delivered.

I was looking to find a reputable roofer to replace my existing roof. I came across MGS construction and decided to give them a call. I got a reasonable quote and decided to hire MGS. They showed up on time and did an amazing job. The roof looked great and everything was cleaned up at the end of the job. I would hire them again without a doubt if needed. I would recommend MGS to anyone looking to have their roof replaced or repaired. You won't regret it.

WOW... Talk about fast service. Called this morning about ice dam removal. The crew was there within an hour and completely removed all the snow and ice in 45 minutes. Excellent finished job and will recommend to anyone needing their services for anything.

Roofing Project
I highly recommend MGS Construction for roofing! WHY?
Mike was very knowledgeable in walking me through the process of putting in a new roof, which entailed a LOT of work!
The roofing project was completed on November 26, 2025, one day before Thanksgiving, by MGS. Mike and the MGS crew completed the project over five full days, working from 7:30 a.m. to 4:30 p.m.
The roof required extensive work. All existing materials had to be completely removed due to significant damage. New plywood was installed across the entire roof before the new shingles could be properly nailed down. The fascia and soffits were severely deteriorated and falling apart, and although the gutters were still in good condition, they had detached from the fascia.
Additionally, both skylights were leaking due to cracked sealant, allowing water to enter the house during heavy rain. The MGS crew also demolished two stories of collapsed laundry rooms that were attached to the rear of the house.
Work Completed on the House:
1) Roofing: The old shingles were completely removed, and new plywood was installed across the entire roof before the new shingles were applied. The roofing work was professionally completed within the first two days of the five-day project.
2) Skylights: Two existing skylights were removed and replaced with two new Velux manual venting skylights (C06), each equipped with a remote-controlled solar shade for opening and closing.
3) Fascia and Soffits: All rotten fascia was removed, replaced with new plywood, and wrapped with aluminum. Damaged sections of the soffits were also removed, replaced with new plywood, and covered with vinyl.
4) Demolition: A two-story section of the house was demolished. The two collapsed laundry rooms were removed, and all debris was thoroughly cleaned up afterward.
Thank you to Mike, Al, Manny, and the MGS crew for the professional installation of the complete roofing system on my home.
