For over 30 years, MassTech has proudly served homeowners across the South Shore and beyond — from roof replacements to full home additions. Recently, a homeowner in Marshfield contacted us about their aging roof. Being just steps from the ocean, the home takes on constant wind, salt air, and harsh coastal weather.
Oceanfront Marshfield is one of the toughest roofing environments in Massachusetts. Nor’easters drive rain horizontally under shingle courses, salt air corrodes standard flashing metals years ahead of schedule, and winter storms will find any shingle that isn’t fully bonded to the course below it. A roof here can’t just meet code — it has to be assembled for the specific abuse this coastline delivers.
MassTech removed the old roofing system and replaced underlayment as needed to ensure long-term structural integrity.
We installed CertainTeed Pro shingles, rated for winds up to 130 mph — an ideal choice for a coastal property like this one.
A wind rating is only as good as the installation behind it, so our coastal fastening schedule — six nails per shingle and sealed starter courses at every edge — came standard.
MassTech also repointed and restored the chimney and replaced a deteriorated drip edge to ensure proper water management and long-term performance.
Chimneys are the most common leak source on coastal roofs: mortar joints erode in salt air, and water tracks down the masonry into the framing below. Restoring the chimney during the roof replacement means the whole system starts its new life together.
At MassTech, we don’t just install roofs — we improve entire exterior systems. If you’re located in Southeastern Massachusetts — from Boston to Cape Cod — MassTech is currently scheduling new exterior projects for homes and businesses.
