Nassau County Roofing Specialists

The roof over your head is your home’s first line of defense.

A roof on Long Island endures heavy snowfall, freezing winter temperatures, nor’easter winds, and humid summer heat. When a roof begins to age, small issues — such as missing shingles, failing valley flashing, or degraded underlayment — can quickly lead to costly water damage inside your walls and ceilings.

As a dedicated roofing and general contracting company rooted in Nassau County, we don’t cut corners. Every roof replacement is completed down to the deck with premium ice-and-water shields, synthetic underlayment, starter strips, proper ridge ventilation, and architectural shingles engineered to withstand up to 130 MPH winds.

Frequently Asked Questions

Roofing questions answered.

How do I know if my roof needs to be replaced or just repaired?

If your roof is under 15 years old and the damage is localized to a few shingles or a single pipe collar, a repair is often sufficient. However, if you see curling, cracking, heavy granule loss in gutters, or if the roof is over 20 years old, a complete replacement is more cost-effective and prevents hidden rot beneath the deck.

How long does a roof replacement take?

Most residential roof replacements in Nassau County are completed in just 1 to 2 days, depending on the square footage, roof pitch, and number of layers to remove. We perform daily site cleanup with magnetic sweepers to ensure your yard and driveway are completely free of nails and debris.

Do you tear off the old shingles or roof over them?

We strongly recommend a complete tear-off down to the wood deck. This allows us to inspect for rotted plywood, replace damaged wood, and install modern ice-and-water shield directly to the deck for a fully warrantied installation that adheres to Nassau County building codes.

Are you licensed and insured in Nassau County?

Yes. Nassau Roofing & Remodeling is fully licensed and insured for both roofing and general contracting throughout Nassau County and Long Island, carrying comprehensive general liability and worker’s compensation coverage.
