This coastal home on Shore Road in Westerly arrived with two very different problems on a single roof: a steep, sun-and-salt-weathered shingle slope that had reached the end of its life, and an adjoining flat section that was ponding water. Rather than force one material to do both jobs, we rebuilt the pitched slope with CertainTeed NorthGate ClimateFlex shingles in Moire Black and restored the low-slope area with a seamless white silicone system, giving the whole home a watertight, ocean-ready roof.
Scope of Work
We started by tearing the failing shingle slope down to the deck and inspecting the sheathing for the soft, delaminated spots that decades of salt air tend to leave behind, replacing any compromised decking before a single course went down. Fresh ice-and-water shield sealed the eaves, valleys, and the chimney base, followed by synthetic underlayment, new drip edge, and starter strip. The NorthGate shingles were run up to a clean line of matching ridge cap. On the abutting flat section, we prepped and re-coated the surface with a fully-adhered silicone membrane, hand-detailing every seam and penetration. It is precisely the kind of two-system roof repair that keeps a shoreline home dry without needlessly tearing off areas that only needed the right coating.
What We Installed (And Why)
The pitched roof got CertainTeed’s NorthGate ClimateFlex, a rubberized SBS-modified asphalt shingle engineered to stay flexible in cold weather and shrug off impact from hail and wind-driven debris. On an exposed coastal roofline like this one, that added elasticity is exactly what resists the freeze-thaw cracking and granule loss that shorten an ordinary shingle’s life within sight of the water.
Where the pitched slope meets the flat section, we built a deliberate, fully-sealed transition so water from the shingles always sheds onto the silicone field and never behind it. The bright white silicone membrane reflects heat and forms one continuous, monolithic surface with no seams to fail, while the Moire Black shingles above give the visible roof a deep, dimensional finish that reads as slate from the street.

Good To Know: Why use two different roofing systems on one house?
Because slope decides everything. Asphalt shingles are designed to shed water quickly down a pitch, so they belong on the steep sections; put them on a near-flat area and water sits in the laps until it finds a way in. A flat or low-slope section needs a monolithic membrane, and a fluid-applied silicone system self-flashes around every curb and pipe with no seams. Matching each material to its slope is what makes the repair last, instead of chasing the same leak every spring.
Why This Approach Works
Restoring rather than gutting kept this project efficient and affordable: we replaced only the shingle slope that had truly failed and renewed the flat section with a coating that bonds to what was already there. The result is a roof where each surface uses the product built for its pitch, the vulnerable transition and chimney are fully flashed, and the homeowner gets years of coastal protection without the cost or disruption of a full structural tear-off.

Westerly, RI
Westerly sits at Rhode Island’s southwestern corner, a shoreline community of shingled beach houses, granite mill history, and homes that take the full brunt of Atlantic weather off Watch Hill and Misquamicut. Roofs here earn their keep against salt, wind, and sun in equal measure. See the range of work we do for local homeowners on our Westerly roofing services page.
