Merrimack River mouth · open Atlantic exposure
Nor'easters come straight up the Merrimack and off Plum Island Sound, driving salt spray and wind-blown rain into the west and south elevations of nearly every home in town. Add January freeze-thaw on 200-year-old sheathing and you get the two failures we're called for most in Newburyport: soaked clapboard at grade and ice damming over the eaves.
We install across Joppa Flats, the South End, The Ridge, Belleville, Plum Island and the North End — on Federal-era brick and clapboard, Greek Revival, antique capes and shingle-style coastal builds.

About Newburyport
Our office is in Newburyport, so this is the town our crews know down to the block. The downtown and South End housing stock is largely Federal and Greek Revival — narrow lot lines, tight side yards, original wood trim profiles worth reproducing rather than covering. On The Ridge and in Belleville the stock shifts to later colonials and capes with more forgiving details, which is where James Hardie® lap and premium insulated vinyl do their best work.
Plum Island and Joppa Flats are a different job entirely. Constant salt load, no wind break, and tidal humidity mean fastener corrosion and paint failure show up years earlier than they do a mile inland. On those addresses we spec fiber cement with stainless-appropriate fastening and HZ5® clearances, and we pay close attention to flashing at every penetration — because on the water, water always finds the shortcut.

Local knowledge
Nor'easters come straight up the Merrimack and off Plum Island Sound, driving salt spray and wind-blown rain into the west and south elevations of nearly every home in town. Add January freeze-thaw on 200-year-old sheathing and you get the two failures we're called for most in Newburyport: soaked clapboard at grade and ice damming over the eaves.
Water is pushed uphill into laps, joints, and flashing. We build the wall to shed it and flash every opening — the panel is the last line of defense, not the only one.
Salt breaks down field-applied paint and corrodes fasteners. Factory-finished fiber cement and correctly specified fastening are what survive it.
Trapped moisture expands and reopens every joint each winter. Proper intake-plus-ridge ventilation and heavy ice-and-water shield stop it at the roof.
Why Coastal
Manufacturer certifications aren't decoration — they're what makes the warranty real. An uncertified install voids most premium product warranties, which is why we hold the top tier with every manufacturer we represent and why every crew on your property is a W-2 employee, never a subcontractor.
Our promise
You don't pay until you're satisfied.
We walk the finished job with you before final payment. If something isn't right, it gets made right first.
Get your free estimateElite Preferred status — the manufacturer's highest contractor tier — which is what keeps the HZ5® install and ColorPlus® finish warranties intact.
A designation held by fewer than 2% of U.S. roofing contractors, and the only way to offer GAF's Golden Pledge® 25-year workmanship coverage.
Recognized on the Inc. 5000 list of America's fastest-growing private companies, and the #1 woman-owned construction company in New England.
Required for any home built before 1978 — which is most of the North Shore. Our W-2 crews follow lead-safe practice on every tear-off.
