MG General Construction Corp says on its website that it works as a roofer in Massachusetts, New Hampshire and Southern Maine, and it claims 10 years in business. On Google it holds 4.9 stars from 47 ratings. A recent Google customer said the company handled wood siding repairs and new windows, with Marco keeping them informed every step of the way. A recent reviewer praised a set of custom gutters and downspouts. In a 2025 review, a customer referred by their general contractor described a leak around the chimney: Marco and Tom arrived at 8am and diagnosed it, and the crew replaced the chimney cap and flashing despite cold weather and snow squalls. That 2025 customer then hired the company to replace the roof, along with skylights, gutter guards and a copper feature, and said the crew protected the decking and landscaping. A 2025 reviewer said Marco and the team replaced the roof on their house. A 2024 customer said the crew replaced a roof along with an abundance of rot in under two days. The work goes beyond roofs. A 2025 customer described the crew replacing rotted wood trim, fascia and other boards with PVC, and said a change order added the morning the crew arrived was still completed by end of day. In a 2024 review, a customer said the company replaced the roof, installed all new windows, built a new front porch and stairs, and rebuilt the back entryway with a small deck. A 2024 customer said the team repaired woodpecker-damaged cedar shake siding. In a 2025 Google review, a customer said the company was cutting corners and trying to cover up rot instead of doing the right thing, and that the whole ordeal seemed sneaky and subpar.
Great bunch of guys! Very detail oriented! Great set of custom gutters and downspouts! Highly Recommend!!!
Always reliable and a great job
MG is fantastic and provided us prompt, courteous, and comprehensive service for our wood siding repairs and new windows. Marco kept us informed every step of the way. I would definitely contact them for any further house repair needs.
Very professional and a great attention to detail. Extremely satisfied with the whole process. Great job with cleanup also.
We appreciate the skilled crew who enabled us to have our home improved professionally. The quality of the work was outstanding as was the cooperative attitude of all involved.

Typical Maine range for this kind of work, from regional averages — not a quote from MG General Construction Corp. Use it to sanity-check bids, then get the real number in writing.
A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.
