Call (866) 756-1978

We’ve been climbing roofs in this neighborhood since 2016. Sal Benedetto started Ridgeline Roofing Co. with the understanding that a harbor town beats harder on a roof than inland streets ever will. Mariners Harbor sits right on the Kill Van Kull, and that tidal strait doesn’t just make for dramatic sunsets - it drives salt-laden air straight into your fasteners, your flashing, and every uncoated metal component on your roofline. We’ve replaced more pitted step flashing and corroded drip edge here than anywhere else on Staten Island. When you call (866) 756-1978, a live person answers, 24 hours a day. No voicemail tree. No callback window. We’ll be there when we say.

Our technicians arrive in uniform, background-checked, and photo-document every inspection from your actual roof - not from the driveway with a scary speech.

We don’t chase the cheapest bid. We offer a square deal: the price we quote is the price you pay. Named for the ridge - the line where a roof proves itself.

Our Roof Repair Services in Mariners Harbor

Flashing Repair

Flashing repair is what we do most in Mariners Harbor, and for good reason. The Kill Van Kull’s salt air attacks uncoated galvanized step flashing and drip edge years faster than it does even a few miles inland. On a 1920s colonial on Van Street near the Kill Van Kull, we replaced corroded galvanized step flashing at a chimney - the post-Sandy Build It Back install had used minimum-spec 26-gauge that was already pitted. Our crew swapped in stainless steel flashing and coated fasteners, and ran a full salt-air corrosion inspection on all valleys and penetrations. We use stainless steel and coated fasteners on every Mariners Harbor flashing job now. It’s the only way to get a repair that outlasts the next storm season.

Leak Repair

Leaks in Mariners Harbor rarely start where you see the stain. The wind channel off Arthur Kill drives rain uphill and sideways, finding every compromised seam. We trace the water path from interior stain to roof penetration, then fix the source - not just the symptom. Most leak repairs in this neighborhood trace back to failed flashing at chimneys, ridge vents, or wall transitions. We document the damage with photos, explain what we found, and give you upfront pricing before we start. Most leak repairs are completed in a single visit.

Valley Repair

Valleys take the most water on any roof, and in Mariners Harbor they take the most punishment. Layer upon layer of old shingles from decades of re-roofing without tear-offs adds dead weight, hiding rotted decking and accelerating failure at valleys. When we open a valley here, we often find three or four shingle layers sandwiching deteriorated plywood. Our valley repair includes full tear-out to solid decking, ice and water shield installation, and proper woven or closed-cut valley shingling. We don’t patch over rot. Done right - and if it’s not, we make it right.

Shingle Replacement

Mariners Harbor’s housing stock - modest 1920s-1950s capes and colonials - often carries multiple shingle installations. Spot shingle replacement is possible when the surrounding field is sound, but we’re honest when a patch won’t last. We stock IKO and Atlas shingles for color-matched repairs, and we’re authorized installers for seven manufacturer lines including Tamko and Boral. If your roof is approaching the end of its useful life, we’ll tell you straight. No patch that buys six months and costs you twice.

Flat Roof Patch

The NYCHA Mariners Harbor Houses and several commercial buildings in the area depend on low-slope and flat membrane roofing. These systems demand entirely different diagnostic expertise than shingle roofs. We patch EPDM, TPO, and modified bitumen systems, and we understand the drainage challenges that flat roofs face when debris collects or scuppers clog. Flat roof patch work in Mariners Harbor typically runs $350-$700 depending on membrane type and access.

Trusted Brands We Service in Mariners Harbor

We’re authorized to install and repair products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Mariners Harbor homeowners, that means we stock the shingles, flashing, and fasteners that match your existing roof - no waiting on special orders, no substitutions with off-brand materials that void your warranty. We keep IKO and Atlas architectural shingles in common colors on our trucks, and we source stainless steel flashing and coated fasteners specifically for salt-air environments. Fast turnaround matters when your living room ceiling is buckling. We don’t make you wait.

Common Roof Repair Problems We See in Mariners Harbor Homes

• Corroded fasteners and drip edge from Kill Van Kull salt spray. Uncoated galvanized metal components pit and fail prematurely, creating leaks at eaves and ridge vents that inland Staten Island roofs simply don’t experience at the same rate.
• Post-Sandy Build It Back replacements failing at chimney step flashing and wall transitions. The rushed program used minimum-spec materials and abbreviated labor scopes. Now, a decade later, those shortcuts are showing. We see this pattern repeatedly on Mariners Harbor streets where Build It Back worked.
• Layered shingles hiding rotted decking. Decades of re-roofing without tear-offs has left many Mariners Harbor homes with excessive dead weight and concealed structural damage, especially at valleys where water concentrates.
• Wind uplift from Arthur Kill and Kill Van Kull channeling. Nor’easter gusts hit Mariners Harbor rooflines harder than inland neighborhoods, testing every fastener pattern. NYC Building Code inspectors here pay particular attention to ridge and eave fastening for good reason.
