WG Construction

WG Construction describes itself as a family-owned roofing, siding and gutter contractor based in Epping, NH, serving the NH Seacoast region and into Massachusetts. The company says it was founded by husband-and-wife team Walter and Maria, with Walter on the craft side and Maria managing business operations. A recent customer with a leaking roof said they got a whole new roof, skylights, custom gutters and trim placed just about a week later. On a recent roof job, a customer said the work ran non stop from 7am to almost dark and the roof was done in less than a day and a half. For a shingle that came loose and fell off, a recent customer said Walter and Ruben fixed it. A recent customer said the company was willing to take a small job like a shed, then did their roof project and replaced rotted plywood. A 2025 customer said the replacement of their 25-year-old roof was done in one day as planned. A 2025 customer who needed a couple of roof vents for bathroom fans said Walter explained he would lay new ice and water barrier around the vent instead of just using silicone; a few heavy downpours later, no water had reached the attic. A 2025 customer said Walter Guaman's team replaced their siding and all their window and roof trim, with Walter recommending CertainTeed Monogram vinyl siding and PVC for the trim. A 2024 customer said Walter traced rain getting into their garage to the likely source around an improperly sealed window, removed clapboard siding, and replaced rotted sheathing, insulation and a 2x6 before putting on new siding. A 2024 Reddit commenter in r/newhampshire said WG Construction did their siding and doors and beat Lowes/DreamWorks in the bid. A recent customer who paid by check gave three stars; they said the company was very communicative when the payment "wasn't received" and stayed professional and patient.
