Roof Replacement on Long Island

Your roof is telling you if it needs replacing. Here are the signs we see on Long Island homes:

Age. Asphalt shingle roofs last 20-30 years on Long Island. If your roof was installed in the late 1990s or early 2000s, it is approaching or past its service life. We see a lot of 2001-2005 roofs right now that are at the end.

Granule loss. Open a gutter downspout. If you see a pile of black or gray granules, your shingles are shedding their protective layer. This accelerates UV damage and means the shingles are failing.

Curling or cracking. Walk across the street and look at your roof. If the shingle tabs are curling up at the edges, cupping in the middle, or cracking, the shingles have lost flexibility and will not survive the next storm.

Multiple leaks. One leak is usually a flashing issue. Three leaks in different locations means the membrane has failed systemically.

Sagging. If the roof deck is visibly sagging between rafters, there is a structural issue that repair cannot address.

Daylight in the attic. Go up to the attic on a sunny day. If you see pinpoints of light through the roof boards, moisture has been getting in and the deck may be compromised.

GAF Timberline HDZ (Our Standard)

Our default recommendation for most Long Island homes. Timberline HDZ is a dimensional architectural shingle with a 130-mph wind rating, Class A fire rating, and a lifetime limited warranty. The LayerLock technology gives it a 30% faster nail-on and a stronger bond than previous generations.

Best for: Colonials, Capes, Ranches, Splits, Hi-Ranches Colors we install most on LI: Charcoal, Pewter Gray, Barkwood, Shakewood, Weathered Wood, Slate Warranty: Lifetime limited (shingle), 25-year manufacturer workmanship (with Golden Pledge)

GAF Timberline AS II (Algae Resistant)

Same performance as HDZ with StainGuard Plus algae protection. Prevents the black streaks that show up on north-facing and shaded roof slopes after 5-8 years. Worth the upgrade if your roof has tree shade.

CertainTeed Landmark Pro

Our alternate premium pick. Heavier shingle weight, Max Def colors with more depth, and a 15-year algae resistance warranty. Some Long Island homeowners prefer the Landmark Pro color palette.

Designer Shingles

For homeowners who want a premium look: GAF Grand Canyon (wood shake appearance), CertainTeed Presidential Shake (slate appearance), Owens Corning Berkshire (deep shadow). These run 40-60% more than standard architectural shingles and look stunning on the right house.

Every full replacement we do includes the complete system, not just the shingles:

1. Full tear-off to the roof deck (we never overlay)
2. Deck inspection — every sheet of plywood or OSB checked for soft spots, rot, and delamination
3. Deck replacement where needed (at cost, no markup surprises)
4. Ice and water shield at eaves, valleys, around all penetrations, and along any roof-to-wall junction
5. Synthetic underlayment on the remaining field
6. Drip edge on all eaves and rakes
7. Step flashing at every wall junction
8. New pipe boots on every plumbing vent
9. Chimney flashing stripped and replaced with new counter-flashing
10. Ridge vent — we convert box vents to continuous ridge vent on most jobs for better attic ventilation
11. Starter strip and hip and ridge cap shingles
12. Permit — we pull it, you sign it, we handle the inspection
13. Dumpster, disposal, and magnetic nail sweep of the entire property
14. Warranty paperwork — filed with the manufacturer and handed to you

All numbers are for a typical 2,000 sqft roof (measured flat), including everything listed above.

See our full pricing guide for what moves the number up or down.

Day 0: Free inspection. Tom goes up on the roof, takes photos, measures, and gives you a written quote within 48 hours.

Day 1 on site: Dumpster dropped, tarps laid over landscaping and walkways, neighbors notified, tear-off begins. Most roofs are stripped to the deck by end of day 1.

Day 2: Deck inspection and replacement of any damaged sheets. Ice and water shield, underlayment, and drip edge installed. Flashing work begins.

Day 3: Shingle installation. Starter strip, field shingles, hip and ridge caps. This is the biggest day on most jobs.

Day 4: Cleanup, pipe boots, final flashing, vent installation, caulking. Tom walks the roof. Magnetic sweep of the yard, driveway, and street. Dumpster hauled. Warranty paperwork delivered.

Typical timeline: 2-4 working days for a standard residential replacement. Weather permitting. We do not install shingles in rain or on a wet deck.

As a GAF Master Elite contractor, we can offer the Golden Pledge warranty, which is the strongest warranty GAF offers. It includes 25 years of workmanship coverage backed by GAF (not just us), plus full material coverage. Fewer than 3% of roofers in the country can offer this.
