Fast, Reliable Roof Replacement & Installation Across Franklin Square
A full roof replacement in Franklin Square, NY typically runs $12,000-$22,000 for a standard asphalt shingle job on a postwar Cape Cod or ranch, with most projects completed in three to five days. Because nearly every home here was built between 1945 and 1965 with skip sheathing rather than solid plywood, expect a full plywood overlay as a standard line item, not an unexpected upsell. Call (866) 756-1978 for a free, no-pressure estimate.
We’ve been climbing Franklin Square roofs since 2016. We know the difference between a 1952 Cape on Monroe Street and a 1961 ranch off Hempstead Turnpike, and we know what hides beneath those original shingles before we pull the first nail. Our crews are background-checked, uniformed, and trained in-house, not hired off a street corner after a storm rolls through. When you call Ridgeline Roofing Co. of New York City, a live person answers, 24 hours a day, seven days a week, including nights, weekends, and the middle of a nor’easter.
Franklin Square sits roughly six miles from the south shore of Long Island, squarely in the path of heavy wet snow, salt-laden marine air, and rapid freeze-thaw cycles that punish low-slope roofs. We’ve replaced roofs on homes from Washington Street to the corners near Rath Park, and we’ve learned what holds up here and what fails. That local knowledge saves you money and headaches down the road.
Why Ridgeline Roofing Co. of New York City Is Franklin Square’s Preferred Roof Replacement & Installation Company
We’ve earned our reputation in Franklin Square one roof at a time. Homeowners here talk to their neighbors. They remember the contractor who showed up in 2012 after Hurricane Sandy and the one who disappeared with a deposit. We’re still here, still answering the same phone number, still sending the same crews to the same streets.
Our response time to Franklin Square is typically same-day or next-day for inspections, and we carry full stock of GAF, CertainTeed, and Owens Corning materials so we’re not waiting on deliveries while your tarp flaps in the wind. We recently finished a full roof replacement on a 1952 Cape Cod on Monroe Street. The existing skip sheathing was rotted near the eaves from years of ice dams, so we added a full ½-inch plywood overlay and installed Owens Corning Duration shingles with stainless steel ring-shank nails to resist algae streaking. The homeowner’s daughter lives three doors down. That’s how we get work in Franklin Square.
Every job is backed by our 90-Day Done Right Promise. Written. No paperwork runaround. No arguing. If it’s not right, we come back and make it right. We’ve stood behind that promise for over 42 years.
Our Roof Replacement & Installation Services in Franklin Square
Full Roof Replacement
Most Franklin Square homes are on their second or third roof now, and the original skip sheathing underneath is often rotted at the eaves and valleys from decades of ice dam damage. We don’t just nail new shingles over old problems. Our full roof replacement service includes tear-off to the decking, replacement of any compromised skip sheathing with solid ½-inch plywood, installation of ice and water shield along all eaves and valleys per Town of Hempstead code, and proper ventilation correction. On a typical Franklin Square Cape Cod, this runs $14,000-$22,000 depending on square footage and pitch.
New Construction Roofing
New builds in Franklin Square are rare given the built-out nature of this 1945-1965 suburb, but we handle additions, dormers, and garage builds with the same thoroughness. We spec solid plywood decking from day one, proper soffit and ridge ventilation, and materials rated for coastal exposure. Our Roof Replacement & Installation team coordinates directly with your general contractor to keep schedules tight.
Asphalt Shingles
Asphalt shingles remain the practical choice for Franklin Square’s postwar housing stock, but not all shingles survive our climate equally. The humid marine air accelerates Gloeocapsa magma algae streaking, often visible within 8-10 years on standard three-tab shingles. We recommend algae-resistant architectural shingles from Owens Corning, CertainTeed, or IKO, installed with stainless or hot-dip galvanized fasteners that resist salt-air corrosion. A typical architectural shingle reroof on a Franklin Square ranch runs $12,000-$18,000 complete.
Metal Roofing
Metal roofing makes sense for Franklin Square homeowners planning to stay for decades. It sheds heavy snow loads better than asphalt, resists algae entirely, and outperforms in coastal salt air. Standing seam metal on a Franklin Square Cape Cod typically runs $22,000-$35,000 installed. We use concealed-fastener systems that eliminate the screw penetrations where salt corrosion starts.
Flat Roofing
The low-slope sections on Franklin Square Cape Cods, over porches and additions, are notorious for ponding and ice dam backup. We install TPO and modified bitumen systems with proper tapered insulation to move water, critical on these original builds where framing wasn’t designed for modern loads.
Tile Roofing
Clay and concrete tile is uncommon in Franklin Square’s original housing stock due to weight constraints on skip sheathing framing, but we’ve engineered upgrades for homeowners who want the look. Requires structural assessment and almost always demands full plywood overlay and potentially rafter sistering.

Common Roof Replacement & Installation Problems We See in Franklin Square Homes
- Skip sheathing rot at eaves and valleys. The spaced board decking original to Franklin Square homes traps moisture where ice dams back up, and by the time shingles fail, the decking beneath is often punky. We find this on roughly eight out of ten tear-offs. Full plywood overlay is not optional here; it’s the only way to nail new shingles properly and meet code.
- Inadequate ventilation in finished attics. Cape Cod second-floor conversions are everywhere in Franklin Square, and almost none were built with soffit-to-ridge airflow. Town of Hempstead inspectors flag this routinely during reroof permits, forcing continuous ridge vents and rafter baffles as a condition of sign-off. We build this into every quote upfront so you’re not surprised mid-project.
- Galvanized fastener corrosion in salt air. Standard electro-galvanized nails and staples corrode within 8-10 years in Franklin Square’s marine environment, leading to shingle blow-off and premature failure. We specify stainless steel or hot-dip galvanized ring-shank nails for all coastal work.
- Algae streaking shortening shingle life. Gloeocapsa magma thrives in our humid, salt-laden air, creating dark streaks that absorb heat and accelerate granule loss. We specify algae-resistant shingles with copper or zinc content, and we never install without proper ventilation that keeps roof decks cooler and drier.

FAQs - Roof Replacement & Installation in Franklin Square
Because your home was almost certainly built between 1945 and 1965 with skip sheathing, spaced boards with gaps between them, rather than solid plywood. Modern shingles and underlayment require a continuous nailing surface, and those gaps make proper installation impossible. Plus, after 60-80 years, that original wood is often rotted near eaves and valleys from ice dam damage. We quote the plywood overlay on every Franklin Square inspection because finding sound skip sheathing underneath is rare enough that we don’t plan for it. Call (866) 756-1978 and we’ll show you photos from your actual attic.
Standard three-tab shingles last 12-15 years here, while architectural shingles with algae resistance typically reach 20-25 years if ventilation is adequate. Salt air, heavy wet snow, and rapid freeze-thaw cycles all shorten life compared to inland climates. If your roof is 18 years old and you’re seeing granule loss or algae streaking, get it inspected. We offer free inspections and photo documentation.
Owens Corning Duration with StreakGuard and CertainTeed Landmark with StreakFighter both use copper granules that resist Gloeocapsa magma, the algae that causes black streaking on Franklin Square roofs within 8-10 years. Standard shingles without this feature will streak sooner and lose granules faster. We specify algae-resistant shingles for every Franklin Square job and back it with our 90-Day Done Right Promise.
Yes, and Town of Hempstead permit inspectors enforce this strictly. Finished attic conversions block original ventilation paths, creating moisture buildup that rots decking and curls shingles. We are required to add continuous ridge vents and soffit baffles as a condition of permit approval on virtually every Franklin Square Cape Cod reroof. We include this in your upfront quote, not as a mid-project surprise.
We can get close, but exact matches to 20- or 30-year-old shingles are rarely possible due to manufacturer color discontinuations and UV fading. We bring sample boards to your home and compare in natural light against your existing roof and siding. For Franklin Square’s closely built neighborhoods where visual continuity matters, we take the time to get it right. Call (866) 756-1978 to schedule a sample review.
