Our Specialty Roofing Services in Syosset
Modified Bitumen Roofing
Syosset’s split-level homes on hilly terrain almost always have a low-slope section - typically 2:12 to 3:12 pitch - over the garage or family room. Nassau County code requires modified bitumen or an equivalent low-slope membrane here, not standard shingles. We install GAF Liberty SBS modified bitumen systems that tie properly into adjacent steep-pitch sections. A typical modified bitumen installation on a Syosset garage or addition runs $8,500-$14,000 depending on square footage and deck condition.
We replaced a failing modified bitumen low-slope section over a garage on a 1968 split-level on Berry Hill Road, where moisture trapped under mismatched 3-tab shingles had rotted the deck. We installed GAF Liberty SBS modified bitumen and tied it into the adjacent steep-pitch Owens Corning Duration Cool shingles, eliminating the leak that had plagued the homeowners for two winters.

EPDM Roofing
For larger flat or low-slope surfaces - commercial buildings, multi-family structures, or substantial residential additions in Syosset’s more densely wooded sections - EPDM (ethylene propylene diene terpolymer) offers a single-ply membrane solution that handles ponding water better than any asphalt-based product. Syosset’s shaded lots keep roof surfaces damp longer after storms, and EPDM’s synthetic rubber composition resists the algae and moss colonization that accelerates degradation on organic materials. Expect $12,000-$20,000 for a typical residential EPDM installation in the 11791 area.

Built-Up Roofing
The traditional BUR system - alternating layers of bitumen and reinforcing fabric, finished with gravel or a reflective coating - still makes sense for certain Syosset structures, particularly older commercial buildings or institutional properties near Jericho Turnpike. The multiple redundant layers tolerate foot traffic during maintenance and provide excellent fire resistance. Built-up roofing in Syosset typically ranges $10,000-$18,000, with the gravel-surfaced variant offering the longest service life in our freeze-thaw climate.

Solar Ready Roofing
Syosset’s south-facing exposures on elevated lots are prime solar territory, but panel installation demands a roof built to outlast the array. Our solar-ready installations use reinforced decking, premium underlayment, and flashings designed for future penetrations - so you’re not tearing off a five-year-old roof to accommodate panels. We coordinate with your solar contractor on load calculations and layout, and we warranty the waterproofing independently of their hardware. Solar-ready specialty roofing in Syosset starts around $14,000 for the roofing component alone, with full system integration running higher.

TPO Roofing
Thermoplastic polyolefin’s white reflective surface cuts cooling loads significantly, a real consideration for Syosset’s larger homes with substantial low-slope sections. TPO heat-welds at the seams, creating a monolithic surface that resists the wind uplift that accompanies Long Island’s coastal storms. We install TPO from authorized manufacturer lines with full system warranties. Typical TPO installations in Syosset run $11,000-$19,000.

Green Roof Systems
For Syosset homeowners with contemporary flat-roof additions or dedicated outbuildings, extensive green roof systems manage stormwater, extend membrane life by shielding it from UV, and integrate with the wooded aesthetic that defines this community. These are specialized installations requiring structural load verification and irrigation planning. Green roof systems in Syosset typically start at $25,000 and require ongoing maintenance contracts.

Trusted Brands We Service in Syosset
We are authorized installers for seven leading manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Syosset homeowners, this means we stock the specific membranes, adhesives, and flashings your job requires - no substitutions, no “equivalent” products that void your warranty.

When we specify an IKO modified bitumen cap sheet or Boral clay tiles for a Syosset installation, that’s exactly what arrives on the truck.
Common Specialty Roofing Problems We See in Syosset Homes
- Algae and moss colonization on shaded north-facing slopes. Syosset’s distinctly wooded residential streets keep roof surfaces shaded and damp longer after storms than the flatter, more exposed south-shore towns. Without algae-resistant shingles or zinc strip installation, black streaking and moss colonization accelerate granule loss and shorten shingle life. We see this constantly on homes off Cold Spring Road and throughout the 11773 ZIP code.
- Ice dam damage along eaves during freeze-thaw cycles. Long Island’s nor’easters create serious ice-dam risk everywhere, but Syosset’s complex rooflines - multiple valleys, dormers, and shed-roof additions - trap snowmelt and channel it under shingles. The resulting interior leaks often masquerade as window or siding problems until a proper roof inspection traces the source.
- Mismatched roofing material on low-slope garage and addition tie-ins. General roofers unfamiliar with Nassau County code frequently apply standard architectural shingles to 2:12-3:12 pitch sections where modified bitumen is legally required. These installations fail prematurely, trap moisture, and rot the deck from beneath - the exact scenario we found on that Berry Hill Road split-level.
- Degraded underlayment in homes hitting their second or third roofing cycle. Syosset’s housing stock was built out almost entirely between 1955 and 1975, meaning thousands of homes are due for full replacement simultaneously. Original felt underlayment has often deteriorated, and modern synthetic underlayments with ice-and-water shield at eaves and valleys are essential for lasting performance in our climate.

FAQs - Specialty Roofing in Syosset
No. Nassau County building code requires modified bitumen or an equivalent low-slope membrane on pitches below 4:12; standard architectural or 3-tab shingles are not permitted and will fail prematurely. We’ve repaired dozens of Syosset garages where previous roofers ignored this requirement, trapping moisture and rotting the deck. Call (866) 756-1978 and we’ll inspect the pitch, document it with photos, and quote the correct system - estimates are free.
Not necessarily. Green streaks indicate algae and moss colonization, which is extremely common on Syosset’s shaded, north-facing slopes and does not automatically mean the shingles have failed. We can often treat active growth and install zinc strips to prevent recurrence, buying years of additional service. If granule loss is severe or the shingles are past 20 years, replacement with algae-resistant products makes more sense. We’ll tell you straight after inspecting - call for our $89 seasonal tune-up or a full evaluation.
Yes. The Town of Oyster Bay requires a building permit for full roof replacements in Syosset, with inspections scheduled at specific project milestones. We handle permit application and inspection scheduling as part of our standard workflow, so you don’t need to visit town hall or coordinate with inspectors yourself. This does add a few days to project start time compared to repair work, which we factor into every timeline we quote.
Sometimes, but recurring leaks on low-slope sections usually indicate systemic failure - improper original material, deteriorated flashing at the transition to steep pitch, or deck damage beneath. A patch might stop water for one season, then fail again when ice dams return. We photograph the full condition and give you honest guidance: if the membrane is near end of life, replacement with proper modified bitumen or EPDM saves money long-term. Call (866) 756-1978 for an inspection - we’ll show you exactly what we’re seeing.
Because the problem often isn’t the shingles. Syosset’s 1955-1975 homes have complex rooflines with multiple dormers, valleys, and shed-roof additions that concentrate water flow. Without proper ice-and-water shield underlayment in valleys, adequate step flashing at dormer walls, and correct ventilation to prevent freeze-thaw ice damming, new shingles alone won’t solve the underlying issue. We inspect the full system - underlayment, flashings, ventilation - not just the surface layer. That’s the difference between a roof that lasts and one that doesn’t.
