Roofing Contractor in Bay Shore
County Roofing Systems
Bay Shore Roofing and Home Exterior Services
SERVING LONG ISLAND AND NY FOR 35 YEARS
Transform Your Bay Shore Home
Bay Shore sits directly on the Great South Bay — which makes it one of the most demanding environments on Long Island for exterior home maintenance.
Salt air off the bay accelerates shingle granule degradation and corrodes exposed metal components faster than in inland communities. South Shore positioning puts Bay Shore homes directly in the path of nor’easter wind and rain, and the community’s housing stock — a mix of postwar ranches, capes, and two-story Colonials built between the 1940s and 1970s — means many roofs are either approaching end of life or already past it.
County Roofing Systems has served Suffolk County’s South Shore communities for over 35 years. We know the coastal conditions Bay Shore homeowners deal with, we know the home styles in this neighborhood, and we know what a correctly installed roof looks like on them.
We hold elite certifications from GAF, Owens Corning, and CertainTeed — ranking us in the top 3% of roofing contractors nationwide — and we manage all Town of Islip permit requirements from start to finish.

Our Services in Bay Shore
We’re a full-service exterior contractor for Bay Shore homeowners across every major category of exterior work.
A BEAUTIFUL NEW ROOF
Roof Replacement & Installation
When a Bay Shore roof has reached the end of its service life — or storm damage has compromised it beyond repair — we handle the complete replacement. That means full tear-off, deck inspection and repair, a complete underlayment system built for coastal conditions, and new shingles from GAF, Owens Corning, or CertainTeed. For additions and new accessory structures, we install from the ground up. All projects are permitted through the Town of Islip Building Department. See our Roof Replacement and Roof Installation pages for full details.
FAST ROOF INSPECTIONS
Roof Repair
Wind damage, flashing failures, valley leaks, and deteriorated pipe boots are all common repair issues in Bay Shore — especially after the coastal storms that routinely move up the South Shore. We diagnose the root cause rather than patching over surface symptoms, and we’re honest about when repair makes sense versus when a full replacement is the better long-term investment. Full details on our Roof Repair page.
PROTECT YOUR HOME
Siding
Salt air is hard on exterior siding, and Bay Shore’s older homes often have wood or early-generation vinyl that has seen better days. We install James Hardie fiber cement siding and CertainTeed vinyl across all Bay Shore home styles, with all flashing and trim details done correctly so the assembly performs for decades. See our Siding Installation page.
EXPAND YOUR HOME
Windows
Older windows in Bay Shore homes are a common source of energy loss and air infiltration — and salt air accelerates seal failure in low-quality window products. We install Marvin and Pella replacement windows with proper flashing and sealing at every opening, protecting both the window’s performance and the surrounding wall assembly. Details on our Window Installation page.
PROTECT YOUR HOME
Gutters
Bay Shore’s coastal rain events push heavy water volume through gutters, and undersized or improperly pitched gutters back up quickly. We install seamless aluminum gutters sized for Long Island’s rainfall intensity, positioned for clean drainage, and we address any fascia or soffit deterioration before installation. See our Gutter Installation page.

Roofing Considerations Specific to Bay Shore Homeowners
Coastal Salt Air and Accelerated Wear
Bay Shore’s direct exposure to the Great South Bay means salt-laden air is a constant presence. Salt air degrades asphalt shingle granules faster than inland conditions, oxidizes exposed metal flashing, and deteriorates sealants at penetrations ahead of their rated service life.
Higher-grade shingle lines with enhanced granule adhesion — GAF Timberline HDZ or Owens Corning Duration with SureNail Technology — hold up significantly better in this environment than budget-tier products, and quality flashing installation matters more here than almost anywhere else on Long Island.
South Shore Wind and Storm Exposure
Bay Shore sits squarely in the track of nor’easters moving up the Atlantic coast, and hurricane storm tracks regularly bring significant wind events to the Great South Bay shoreline.
Wind uplift resistance is a critical spec when selecting shingles for this area — both GAF Timberline HDZ and Owens Corning Duration carry 130 mph wind ratings when installed to manufacturer specifications. Starter shingles, proper nail placement, and sealed ridge caps are what make those ratings real, and they require a certified installer to execute correctly.
Aging Housing Stock and Flat Roof Additions
Bay Shore’s postwar housing base means a large percentage of homes are working with original or early-replacement decking. Deck condition at tear-off varies significantly, and deteriorated sheathing discovered during removal adds scope to any replacement project.
Many Bay Shore homes also have low-slope or flat roof sections over rear additions, screen rooms, or garage conversions — these require EPDM or modified bitumen systems rather than shingles, and we handle both.
Town of Islip Permits
All roofing work in Bay Shore falls under the Town of Islip Building Department. County Roofing handles all permit filings and inspections on every project — you don’t need to navigate the process yourself.
Long Island Deserves Industry-Leading Protection
Lifetime Material, Lifetime Workmanship Warranty
CertainTeed’s lifetime-limited transferable warranty is a true industry standout. Whereas other manufacturers only warrant against defects that cause leaks, CertainTeed protects your Melville home against all manufacturing defects, including aesthetic defects.
County Roofing Systems can offer you the longest warranties available because we’re a CertainTeed SELECT ShingleMaster, a certification only 1% of contractors qualify for.

How Our Roof Installation Process Works
- Complete deck preparation: We remove all existing materials down to bare wood, inspect every section of decking for rot, soft spots, and deterioration, and replace compromised sheathing before any new material goes down
- GAF WeatherWatch ice-and-water shield: Applied along all eaves (minimum 3 feet from the edge), through every valley, and around all penetrations. Particularly critical in Bay Shore given coastal storm exposure and wind-driven rain events
- GAF FeltBuster synthetic underlayment: Installed across the remaining deck for superior tear resistance and weather protection throughout the installation window
- Drip edge and flashing: Aluminum drip edge along all rakes and eaves; step and counter flashing at walls and dormers; valley flashing; pipe boot seals at all plumbing penetrations; chimney flashing and counter-flashing with proper sealant for salt air conditions
- GAF Pro-Start starter course: Specialized starter shingles installed along eaves and rakes, creating a sealed edge that resists wind uplift under South Shore storm conditions and establishes accurate alignment for every course above it
- Shingle installation course-by-course: Chalk lines snapped for straight courses; correct nail placement and quantity per manufacturer spec; hand-sealing in high-wind zones; GAF Timberline HDZ or Owens Corning Duration applied in full compliance with certification requirements
- GAF TimberTex ridge cap: Specialized ridge cap shingles at all peaks and hips, properly overlapped and nailed, completing the sealed ridge over the GAF Cobra ridge vent
- 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. It really was a pleasure, and I will definitely be recommending Keith and his crew to anyone I know looking to do roof work.

Bay Shore Roofing FAQs
How long does a roof replacement take on a typical Bay Shore home?
Most single-family replacements in Bay Shore are completed in one to two days. Homes with flat roof sections, storm damage discovered at tear-off, or deck repairs that surface during removal may require additional time. We give you a realistic schedule before any work begins.
Do you handle permits with the Town of Islip?
Yes. County Roofing manages all permit filings and inspections with the Town of Islip Building Department on every project. You don’t need to do anything on the permitting side.
What shingles hold up best near the Great South Bay?
For coastal Bay Shore properties, we recommend GAF Timberline HDZ or Owens Corning Duration — both carry 130 mph wind ratings when installed correctly and use enhanced granule adhesion technology that holds up better in salt air environments than entry-level products.
My home has both a pitched roof and a flat section over a rear addition. Can you handle both?
Yes. We install shingle roofing on pitched sections and EPDM or modified bitumen systems on flat and low-slope sections in a single project, so everything is installed and warranted together under one contractor.
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.
Do you handle siding, windows, and gutters 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. Bay Shore homeowners dealing with salt air damage often find that multiple exterior components need attention at the same time, and handling it all under one contractor is simpler and more efficient.
How do I know if my roof needs to be replaced or just repaired?
Age and overall condition are the two biggest factors. A roof under 15 years old with storm damage to one section is usually a repair candidate. A roof that’s 20-plus years old with significant granule loss, multiple failing areas, or deck issues that surface during inspection typically makes more sense to replace. We’ll give you a straight answer after looking at it — not a push toward the larger project if repair is genuinely the right call.
