Why Ridgeline Roofing Co. Is Cohasset’s Preferred Specialty Roofing Company

Our Specialty Roofing Services in Cohasset
Modified Bitumen Roofing
Modified bitumen is our go-to for flat or low-slope sections on Cohasset’s older homes - often the rear additions, breezeways, or garage roofs tucked behind a steep-pitch Colonial main house. The material handles the thermal cycling that Cohasset’s coastal climate delivers, expanding and contracting through summer humidity and winter freeze without cracking. We install torch-applied and self-adhering systems from Atlas and GAF, layered with proper base sheets and cap sheets rated for wind uplift. On oceanfront properties, we upgrade to heavier-gauge fastening patterns because standard specs don’t survive the ledge exposure.
Built-Up Roofing (BUR)
For historic commercial buildings and some estate outbuildings around Cohasset Center, built-up roofing remains the right choice - multiple layers of bitumen and reinforcing fabric that create a thick, durable membrane. The system performs well on roofs with heavy HVAC or where foot traffic is expected. We specify coal-tar pitch or modified asphalt based on the existing substrate, and we always inspect the underlying decking for salt corrosion before we quote. A BUR system properly installed on a Cohasset property should last 20-25 years, even with the coastal exposure.
EPDM Roofing
EPDM - the black rubber membrane - works for flat-roof additions on Cohasset homes where weight and cost matter, but performance can’t be compromised. We’ve installed EPDM on bluff-top properties where the homeowner wanted a clean, modern solution for a contemporary addition without disturbing the historic main roofline. The material’s flexibility handles building movement well, and with proper seam tape and cover tape detailing, it resists the UV and ozone exposure that comes with open coastal siting. Ballasted or fully-adhered installation depends on wind exposure; on Atlantic-facing homes, we rarely recommend ballast alone.
Solar Ready Roofing
Cohasset’s south-facing roof planes on homes along King Street and Beechwood Street are prime for solar, but the roof underneath has to be built for it. We install solar-ready decking and underlayment systems that won’t need replacement when panels go up five or ten years later. On slate or shake roofs, this requires careful planning - the mounting hardware can’t compromise the historic material. We coordinate with solar installers to specify flashed standoffs that penetrate properly and seal against the salt air.
TPO Roofing
White TPO membrane reflects heat, which helps on flat sections of Cohasset homes where summer sun beats down and interior cooling costs climb. We see this on contemporary renovations and on some estate outbuildings. The heat-welded seams create a monolithic surface that resists ponding water, though on Cohasset’s older structures with less-than-perfect drainage, we always address slope correction before membrane installation.
Green Roof Systems
For the occasional modern build or ambitious renovation in Cohasset, we install intensive and extensive green roof assemblies - engineered growing medium, drainage layers, and root barriers over a waterproof membrane. The load requirements are substantial, so we verify structural capacity before quoting. The payoff is stormwater management and thermal mass, valuable on properties where runoff regulations or energy goals matter.

Trusted Brands We Service in Cohasset
We are authorized installers for GAF, CertainTeed, Owens Corning, Atlas, Tamko, and Boral - seven manufacturer lines, not substitutions pulled from a job-lot warehouse. For Cohasset homeowners, this means we stock the specific flashing gauges, fastener types, and membrane grades that match your existing roof. When a Village-area slate roof needs replacement copper valley flashing, we don’t substitute aluminum and hope for the best. We order the 20-ounce copper, cut it on site, and solder the seams. That specificity is why our turnaround on specialty material orders stays tight, and why repairs don’t turn into callbacks.
Common Specialty Roofing Problems We See in Cohasset Homes
- Salt spray corrosion on oceanfront flashing. On the exposed granite bluffs from Atlantic Avenue to Government Island, standard aluminum or galvanized flashing corrodes within two to three seasons. We find fasteners dissolved, seams lifted, and water staining on interior ceilings that traces directly to metal failure. The fix is heavier-gauge copper or stainless steel, ring-shank fasteners, and wider sealing margins - details contractors working inland towns routinely omit.
- Ice dam damage at eaves and valleys. Cohasset’s older homes, many with original insulation and complex dormer configurations, build heat loss that melts snow from below. Water runs down the roof, refreezes at the cold edge, and backs up under slate or cedar shakes. We see this every winter on the steep pitches near Cohasset Common. Proper repair requires addressing attic ventilation and insulation, not just patching the leak point.
- Wind uplift on improperly fastened slate and shake. Nor’easters hit Cohasset with full force, and steep roofs with multiple planes create turbulence that pulls at edges and ridges. Slate installed with standard copper nails, or shakes with insufficient exposure, lift and break. We specify ring-shank stainless fasteners and reduced exposure on windward slopes.
- Material mismatch on historic repairs. A previous owner or an inexperienced contractor patches a slate roof with asphalt shingles, or replaces cedar shakes with synthetic. The repair fails cosmetically and functionally, and Cohasset’s historically conscious homeowners notice. We source matching slate from Vermont quarries, hand-split cedar from Pacific Northwest mills, and standing-seam copper fabricated to original profiles.

What moves a project to the higher end: steep pitch requiring scaffolding, matching rare or discontinued materials, structural decking replacement from long-term leak damage, and oceanfront access constraints. What keeps costs controlled: catching problems during routine inspection, repairing rather than replacing where possible, and choosing compatible modern materials where historic match isn’t required.

FAQs - Specialty Roofing in Cohasset
It is probably not copper. Many contractors install aluminum or galvanized steel labeled as “flashing” on oceanfront properties, and the salt-laden wind on Cohasset’s exposed bluffs dissolves standard metals within two to three seasons. True 20-ounce copper and 304 stainless steel resist salt corrosion; we specify these with ring-shank fasteners and soldered seams on every Atlantic-facing job. Call (844) 563-1816 and we’ll inspect what you actually have up there - estimates are free.
Yes, we source matching slate from active Vermont quarries and fabricate replacement pieces to the original size, thickness, and nail-hole pattern. Cohasset’s Village-area Colonials and Victorians were built with hard-vein slate that lasts 100+ years when properly maintained; partial replacement is usually preferable to full tear-off. We also inspect the underlying decking and insulation while we’re up there, since ice dam damage often hides beneath intact surface slate. Call for a photo-documented inspection.
Ice dams form where heat loss melts snow from below and the water refreezes at cold eaves; on Cohasset’s complex rooflines with multiple dormers, the thermal patterns are irregular and the dam locations unpredictable. We address this with targeted air sealing, proper soffit-to-ridge ventilation, and where appropriate, ice-and-water shield membrane extending well past the interior wall line. On historic slate or shake roofs, we avoid disruptive interior work when possible, instead using vented base layers that preserve the original ceiling. The specific solution depends on your attic configuration - we inspect before we recommend.
EPDM can work, but wind exposure on Cohasset’s open bluffs requires fully-adhered or mechanically-fastened installation - never ballast alone. We also specify thicker membrane (90-mil versus standard 60-mil) and reinforced seam tape because the uplift forces here exceed inland design standards. For some bluff properties, we recommend modified bitumen or TPO instead, depending on the specific wind corridor and the homeowner’s maintenance expectations. We’ll walk you through the trade-offs after we see the site.
Yes, and this is work we do regularly in Cohasset. On a historic estate on Atlantic Avenue facing the open ocean, our crew replaced a failing standing-seam copper roof that had been improperly installed with standard aluminum flashing. Within two winters, the salt spray had corroded the fasteners, causing leaks. We retrofitted with soldered copper flashing and stainless ring-shank nails, matching the original material and sealing margins to withstand the exposed ledge conditions. We repair, replace, and extend standing-seam systems in copper, zinc, and coated steel - always with fasteners and flashing appropriate to Cohasset’s coastal exposure.
