Architectural asphalt shingles from GAF Timberline HDZ and Owens Corning Duration are the #1 residential roofing choice on Long Island — 30+ year lifespans and 130 mph wind warranties when installed with the required 6-nail pattern. Roofing Time Inc is certified by both manufacturers and installs the full system: ice-and-water shield, synthetic underlayment, drip edge, hand-detailed flashings, and shingles.
Shingle Roofing: The Long Island Standard
Drive through any Bellport neighborhood, any Patchogue subdivision, any Shirley or Mastic street — and you're looking at shingle roofs. Asphalt shingles cover roughly 80% of American homes for a reason: they deliver an unbeatable combination of cost, curb appeal, performance, and lifespan when installed correctly.
But not all shingle roofs are created equal. There's a massive gap between a cheap 3-tab strip shingle roof nailed on in a weekend and a properly installed architectural shingle system with full underlayment, ice-and-water shield, and hand-detailed flashings. We only do the latter.
Architectural vs. 3-Tab: Why We Only Install Architectural
Three-tab shingles — the flat, uniform-looking kind — are the old standard. Cheaper, thinner, shorter lifespan (typically 15–20 years), and lower wind ratings. We won't install them except in rare matching situations.
Architectural shingles (also called dimensional or laminated shingles) are the modern standard. They're multi-layered, thicker, heavier, and look dramatically better on a roof — with shadow lines that mimic cedar shake. More importantly, they're engineered for significantly better performance:
- 30-year to lifetime warranties from major manufacturers (GAF, Owens Corning, CertainTeed).
- Wind ratings up to 130 mph when installed with manufacturer-specified nailing patterns.
- Algae-resistant granules that prevent the black streaking common on older roofs.
- Better impact resistance — Class 3 or Class 4 impact ratings available for hail and debris.
Why Wind Rating Matters on Long Island's South Shore
Here's something homeowners in Bellport, Patchogue, and along the South Shore need to understand: you live in a high-wind zone. Nor'easters routinely deliver sustained winds of 40–50 mph with gusts over 70. Hurricane remnants (Sandy, Irene, Ida) have pushed 80+ mph gusts over Suffolk County in recent years.
A shingle's wind rating isn't just marketing. GAF Timberline HDZ with proper 6-nail installation carries a 130 mph wind warranty. Owens Corning Duration shingles with SureNail technology offer similar ratings. These numbers matter — and they only apply if the shingles are installed exactly to spec.
The 6-nail rule: Long Island's wind zone requires 6 nails per shingle, not the standard 4 used in calmer climates. Crews that still nail 4 nails per shingle in Suffolk County are voiding the manufacturer warranty and giving you a roof that will fail in the first big storm. We nail 6, every time, no exceptions.
The Full Roof System — Shingles Are Just The Top Layer
When we install a new shingle roof, the shingles themselves are the final piece of a complete weatherproofing system. Here's what goes underneath:
1. Sound Roof Deck
Every shingle job starts with tearing off the old roof to bare decking, then inspecting and replacing any rotted or sagging plywood. We've seen too many "quick" roof replacements laid over failing OSB — it's a ticking clock.
2. Ice & Water Shield
A self-adhering waterproof membrane applied along all eaves, valleys, and roof penetrations. On Long Island's South Shore, we extend ice-and-water shield at least 3 feet up from the eave to protect against ice dams. This is code, but many contractors skimp here.
3. Synthetic Underlayment
Modern synthetic underlayment replaces the old #15 or #30 felt paper. It's stronger, tear-resistant, and provides a secondary water barrier if a shingle lifts in high wind.
4. Drip Edge & Flashing
Metal drip edge at eaves and rakes, step flashing at every sidewall, counter-flashing at chimneys, and purpose-formed flashings at all penetrations. This is where experience shows. Bad flashing details are the #1 cause of premature shingle roof failure.
5. Shingles, Nailed to Spec
6 nails per shingle, proper nail placement (not too high, not too low), straight courses, and properly finished ridge caps and hip caps. Then and only then is the roof complete.

Tom Melillo has installed thousands of shingle roofs across Long Island in 35 years. When he specs a shingle roof for a Bellport home, he's factoring in sun exposure, tree cover, wind patterns from the bay, chimney count, ice dam history, and the homeowner's long-term plans. That's the difference between a contractor and a craftsman.
