Oyster Bay, NY Roofing and Home Exterior Services
SERVING LONG ISLAND AND NY FOR 35 YEARS
Transform Your Oyster Bay Home
The Town of Oyster Bay covers the entire eastern half of Nassau County — and the range of homes and roofing demands across it is wider than almost anywhere else on Long Island.
The North Shore communities along Cold Spring Harbor and Oyster Bay harbor — Oyster Bay hamlet, Cold Spring Harbor, Laurel Hollow, Oyster Bay Cove, Upper Brookville — feature a mix of historic Gold Coast estates, custom-built homes on wooded lots, and mid-century Colonials and ranch homes that are now well into their second half-century.
The South Shore corridor through Massapequa, Wantagh, and Seaford faces completely different conditions: South Shore wind and storm exposure, older postwar housing stock, and the accelerated wear that comes with proximity to the water. Running down the center of the town are established suburban neighborhoods in Hicksville, Syosset, Plainview, and Bethpage — their own mix of 1960s and 1970s ranches and split-levels, many with original or early-replacement roofing systems.
County Roofing Systems has served Nassau County’s North Shore communities for over 35 years, including towns and neighborhoods throughout the Town of Oyster Bay. We know the home styles across this township, we work within the Town of Oyster Bay Building Department’s permit process, and we deliver the same quality on every job regardless of where in the town your property sits.
We hold elite certifications from GAF, Owens Corning, and CertainTeed — placing us in the top 3% of roofing contractors nationwide — and we handle all permit requirements in-house.

Our Oyster Bay Roofing and Home Exterior Services
We’re a full-service exterior contractor for Oyster Bay homeowners across every major category of exterior work.
A BEAUTIFUL NEW ROOF
Roof Replacement & Installation
When an Oyster Bay roof has reached the end of its service life — or storm damage has made repair impractical — we handle the complete replacement. That means full tear-off, thorough deck inspection with replacement of any compromised sheathing, a complete underlayment system suited to your home’s location and exposure, and new shingles from GAF, Owens Corning, or CertainTeed. For additions and new construction, we install from the ground up. All standard projects are permitted through the Town of Oyster Bay Building Department. See our Roof Replacement and Roof Installation pages for full details.
FAST ROOF INSPECTIONS
Roof Repair
Wind damage, flashing failures at complex dormers and valleys, deteriorated chimney counter-flashing, and storm-related impact damage are all common across Oyster Bay’s varied housing stock. We diagnose root causes rather than surface symptoms, and we’re honest about when repair is the right call versus when replacement makes more long-term sense. Full details on our Roof Repair page.
EXPAND YOUR HOME
Siding
Older homes throughout Oyster Bay’s established neighborhoods frequently present aging wood or vinyl siding that has run its maintenance cycle — and North Shore waterfront properties deal with moisture and wind-driven rain that accelerates deterioration. We install James Hardie fiber cement siding and CertainTeed vinyl across all home styles, with all flashing and trim details handled correctly. See our Siding Installation page.
WINDOW SERVICES
Windows
Aging windows are common throughout Oyster Bay’s mid-century housing stock — a consistent source of drafts, energy loss, and moisture infiltration at the frame. We install Marvin and Pella replacement windows with proper flashing and sealing at every opening. Details on our Window Installation page.

Roofing Considerations for Oyster Bay Homeowners
North Shore Wooded Lots and Complex Rooflines
The North Shore communities in the Town of Oyster Bay — Oyster Bay hamlet, Cold Spring Harbor, Laurel Hollow, Mill Neck, Upper Brookville — frequently feature homes set on heavily wooded lots with steep-pitched, multi-plane rooflines. Large trees keep roof surfaces shaded for extended periods, accelerating algae and moss growth that degrades shingles over time.
Complex rooflines with multiple dormers, valleys, and intersecting planes also concentrate water flow in ways that flat rooflines don’t, making flashing installation at every transition point more critical. We use GAF Timberline shingles with StainGuard Plus algae-resistant granules on shaded North Shore properties, and we take every valley and penetration seriously regardless of roofline complexity.
South Shore Wind and Storm Exposure
The southern half of Oyster Bay — Massapequa, Massapequa Park, Wantagh, Seaford — faces South Shore exposure conditions that are meaningfully different from the North Shore. Nor’easters moving up the Atlantic coast and hurricane-track storm events bring sustained wind and heavy rain to this portion of the town on a regular basis.
Wind uplift resistance is a critical specification for South Shore Oyster Bay properties. GAF Timberline HDZ and Owens Corning Duration both carry 130 mph wind ratings when installed to certification standards — and those ratings depend on correct starter shingle placement, nail pattern, and sealed ridge caps, which require a certified installer to execute properly.
Aging Mid-Century Housing in the Suburban Interior
The interior communities of Hicksville, Syosset, Plainview, and Bethpage are dominated by ranch homes, split-levels, and Colonials built between the late 1950s and mid-1970s. Many of these homes are now on their second or third roofing system, and the deck sheathing underneath may reflect decades of repairs, patches, and deferred maintenance.
Deck condition at tear-off on these homes varies. We inspect every section of exposed sheathing, document what we find, and replace what’s compromised before any new material goes down.
Town of Oyster Bay Permits
Most roofing work in the Town of Oyster Bay is permitted through the Town Building Department. Several incorporated villages within the town — including Massapequa Park, Old Westbury, and East Williston — maintain their own building departments with separate permit processes.
County Roofing identifies the correct permitting authority for your specific address and manages all filings and inspections from start to finish.

- Final inspection and cleanup: Full roof walkthrough, verification of all penetration seals and flashing, magnetic nail sweep of the entire property, gutter cleaning, and complete site restoration
County Roofing Systems Reviews

County Roofing replaced my aging roof and all of the gutters. Keith was truly professional, performing the estimate, supervising the work, and keeping me informed at every step. The results were beautiful. I would not hesitate to recommend County Roofing Systems to anyone.
Our roof was a bit of a tricky project, but Keith’s crew handled every nuance flawlessly—right down to protecting the gutters and surrounding landscaping. The workmanship is top-tier; you can see and feel the quality in every shingle. Equally impressive, Keith was completely transparent about costs and timelines, and his quote was the most competitive we received by a mile.
I had County Roofing Systems install new vinyl siding and gutters and leaders. Keith was very professional as well as personable and really knew his craft. Keith was on site the entire time with his crew. The house came out perfect. Just want to say thanks to Keith and I would give 5 stars plus! Thanks again Keith for all your good work.
Had a fantastic experience with County Roofing! Keith was extremely thorough. He walked through every detail, explained all the color options, and offered thoughtful recommendations that made a big difference. His crew did an outstanding job, and our new roof looks absolutely amazing.
Highly recommend County Roofing to anyone looking for a reliable, skilled roofing team!
Recently had a new roof done by County Roofing, and am so thankful for having met Keith. He is fair with the price, knowledgeable about his work, patient, responsive and professional.

Oyster Bay Roofing FAQs
How long does a roof replacement take on a typical Oyster Bay home?
Most single-family replacements are completed in one to two days. Homes with complex multi-plane rooflines, multiple dormers, or deck repairs discovered during tear-off may require additional time. We give you a realistic schedule before work begins.
Do you handle permits with the Town of Oyster Bay Building Department?
Yes. County Roofing manages all permit filings and inspections on every project. We identify whether your address falls under the town department or an incorporated village department — several villages within the town maintain their own permit processes — and handle it from start to finish.
My home is on the North Shore with a lot of tree shade. Does that affect my roof?
It does over time. Sustained shade keeps moisture on shingles longer and promotes algae and moss growth, which degrades granules and shortens shingle life. We recommend GAF Timberline shingles with StainGuard Plus algae-resistant granules for shaded North Shore properties — a meaningful upgrade in that environment.
My home is in Massapequa or Wantagh near the South Shore. What shingles are best?
For South Shore properties in the Town of Oyster Bay, we recommend GAF Timberline HDZ or Owens Corning Duration — both carry 130 mph wind ratings when installed to certification standards and use enhanced granule adhesion that holds up well under storm exposure. Proper starter shingle placement and sealed ridge caps are what make those wind ratings real.
My home has a complex roofline with multiple dormers and valleys. Is that more difficult to roof?
It requires more precision — particularly at the flashing details where dormers meet the main roof, in the valleys between intersecting planes, and around chimney or skylight penetrations. These are exactly the spots where water finds its way in if the installation isn’t executed correctly. Our installers are trained specifically on these details and we don’t cut corners on flashing regardless of complexity.
Do you handle siding and windows as well as roofing?
Yes — we’re a full exterior contractor. We install James Hardie and CertainTeed siding, Marvin and Pella replacement windows, and seamless aluminum gutters in addition to all roofing services. Handling multiple exterior projects under one contractor keeps the process streamlined and reduces the number of crews on your property.
What financing options are available?
We offer financing with approvals as low as 0% interest, up to 15-year terms, with monthly payments starting at $149. Quick approval, no income check required. Ask about current offers when you call for your estimate.
