Our Roof Replacement & Installation Services in Farmingdale
Full Roof Replacement
Farmingdale’s post-WWII housing stock is cycling through second and third replacements now. Those original Cape Cods and ranches off Conklin Street and Fulton Street often hide three or four layers of shingles, improper flashing from 1970s dormer additions, and rotted sheathing at the eaves. We strip to deck, replace damaged wood, and install proper underlayment before the new roof goes on. A square deal: the price we quote is the price you pay.
Asphalt Shingles
This is what most Farmingdale homes wear, and for good reason. We install CertainTeed Landmark Pro and Owens Corning Duration systems with wind-rated fasteners rated to 110 mph on the Nassau side, where Oyster Bay requires higher wind-load compliance. The salt-laden air here, five to eight miles north of the Great South Bay, strips granules faster than inland towns. We specify algae-resistant shingles with heavier granule bonding for Farmingdale’s conditions. Our Roof Replacement & Installation team will walk you through color and warranty options that fit your block.
Flat Roofing
The low-slope sections on Farmingdale’s ranch additions and garage roofs demand different materials. We install modified bitumen and TPO systems with proper drainage planning, critical on shallow pitches where meltwater pools instead of runs. Freeze-thaw cycling here is brutal on flat seams.
Metal Roofing
For homeowners staying put on their Farmingdale property, standing-seam metal offers 50+ year performance with proper installation. We engineer ventilation and ice-dam prevention into every metal system, essential on 1950s ranches with minimal attic insulation.
New Construction
Building new in Farmingdale? We coordinate with your framing crew early to specify proper sheathing, valley construction, and flashing details before walls close in. Cheaper to build right than to cut in later.

Trusted Brands We Service in Farmingdale
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Farmingdale’s salt-air environment, we typically recommend CertainTeed’s Landmark Pro with StreakFighter algae resistance or Owens Corning Duration with SureNail technology for wind uplift protection. We stock common repair materials locally, so a torn shingle from last night’s wind doesn’t wait two weeks for parts. Every brand we install carries full manufacturer warranty, registered in your name, not ours.
Common Roof Replacement & Installation Problems We See in Farmingdale Homes
- Corroded dormer flashing buried under multiple shingle layers. The single most recurring leak call we get in Farmingdale traces to 1970s or 1980s shed dormers added without proper counter-flashing or ice-and-water shield. Salt air corrodes the step flashing. Wind-driven rain finds the gap. Water shows on the ceiling before you see damage outside.
- Ice dams on under-insulated 1950s attics. Farmingdale’s original ranches and Cape Cods were built with R-19 or less in the roof deck. Winter nor’easters dump wet snow, heat escapes, ice builds at the eaves, and water backs up under shingles through unsealed valleys.
- Granule loss accelerated by salt air. That proximity to the Great South Bay means airborne salt crystals embed in shingle surfaces and accelerate granule shedding. A 25-year shingle in Farmingdale often looks like a 35-year shingle in Syosset at year 15.
- Wrong-county permit pulled, inspection failed, job stopped. Because Farmingdale straddles the Nassau-Suffolk line, a contractor who pulls an Oyster Bay permit for a Babylon-jurisdiction address faces failed inspection, costly rework, and weeks of delay. We verify jurisdiction before the first nail.

FAQs - Roof Replacement & Installation in Farmingdale
Yes. Nassau-side Farmingdale addresses fall under Town of Oyster Bay jurisdiction, while Suffolk-side parcels in East Farmingdale answer to Town of Babylon. Each town has separate wind-load requirements, inspection schedules, and fee structures. We verify your exact jurisdiction from your address before pulling any permit, so your job passes inspection the first time. Call (866) 756-1978 and we’ll confirm yours.
Town of Oyster Bay (Nassau side) requires 110 mph wind resistance for asphalt shingles; Town of Babylon (Suffolk side) typically accepts 90 mph but we specify 110 mph across all Farmingdale jobs for margin. We use six-nail patterns and wind-rated fasteners on every installation. The number on your estimate specifies exactly what you’re getting - no substitutions.
Yes, with proper engineering. Shallow pitches in Farmingdale’s 1950s ranches demand enhanced ventilation (often adding ridge and soffit vents where original construction omitted them) and ice-and-water shield at all eaves and valleys. We design the system for your specific roof geometry, not a one-size template. Metal’s smooth surface actually sheds snow faster than shingles when ventilation is correct.
Look for water stains on the ceiling directly below the dormer, granule buildup in gutters beneath the valley, or lifted shingles at the dormer-to-roof junction. From the ground, you may see rust streaks on the siding below the dormer corner. But the failure is often hidden under successive shingle layers. We recommend a professional inspection with photos - our seasonal $89 Tune-Up includes dormer flashing evaluation. Call (866) 756-1978 to schedule before the next nor’easter.
Salt-laden air from the Great South Bay, roughly five to eight miles south, deposits corrosive crystals on shingle surfaces. These crystals expand and contract with humidity changes, prying granules loose faster than the thermal cycling alone would. Farmingdale’s exposure is measurably harsher than Syosset or Hicksville, which sit further inland. We specify algae-resistant shingles with enhanced granule adhesion for this exact environment.
We recently replaced a 1950s Cape Cod on Merritts Road where a 1980s shed dormer had been added without ice-and-water shield. The step-flashing was corroded from salt air, and each nor’easter was driving water into the living room. We installed GAF WeatherWatch in the valleys and a full CertainTeed Landmark Pro system with wind-rated fasteners to handle the 110-mph design winds required on the Nassau side. Done right - and if it’s not, we make it right.
