Roof Replacement

Roof Replacement on Long Island

Complete tear-off and re-roof — done in days, built for decades.

Short answer

A full roof replacement removes every layer down to the plywood deck, repairs any rot we find, then rebuilds the roof as a system: ice-and-water shield at the eaves and valleys, synthetic underlayment, new flashing, architectural shingles and balanced ridge-and-soffit ventilation. Most Long Island homes are finished in one to two days. LaRocco Roofing & Siding replaces roofs across Nassau County, Suffolk County and Queens.

There is a point where patching stops being economics and starts being denial. When the shingles are curling across whole slopes, when the granules are filling the gutters, when you've had three leaks in two years in three different places — you are paying for a new roof already, just in installments, to the wrong people.

A LaRocco replacement is a complete tear-off. We do not shingle over your old roof to save a day of labor. Going over the top hides rotten decking, adds weight the framing was never sized for, cooks the new shingles against the old ones and voids most manufacturer warranties. We take it to the wood, fix what's underneath, and build back up.

What's included

Every roof replacement job covers

01

Full tear-off to the deck

Every layer of old shingle, felt and nail comes off and goes in the dumpster.

02

Deck inspection and repair

Soft or rotted plywood is replaced before anything goes back down. You approve the count.

03

Ice-and-water shield

At eaves, valleys, and around every penetration — the barrier that stops ice-dam backup.

04

Synthetic underlayment

Across the whole deck. Lighter, stronger and far more tear-resistant than felt paper.

05

New flashing throughout

Step, chimney, sidewall and pipe-boot flashing replaced — not reused, not caulked over.

06

Balanced ventilation

Ridge vent paired with clear soffit intake so the attic breathes and the shingles last.

07

Architectural shingles

Owens Corning and comparable systems, wind-rated and fastened for coastal exposure.

08

Clean-up and haul-away

Magnet sweep, dumpster removed, and a walkthrough before we ask for final payment.

Know the signs

Signs your Long Island roof needs replacing, not repairing

If two or more of these sound like your house, book the free inspection. It costs nothing and it settles the question.

  • Shingles curling, cupping or lifting at the edges across whole slopes
  • Bald patches where the granules have worn off — check your gutters for the grit
  • Multiple leaks in different areas within the same year
  • Daylight visible through the roof boards from inside the attic
  • A deck that feels spongy or dips underfoot
  • Dark staining or mold on the attic sheathing
  • The roof is 20+ years old and has already been repaired more than once
  • Interior ceiling stains that come back after every heavy rain
Materials

Roofing materials we install

01

Architectural asphalt shingles

The default on Long Island for good reason: strong wind ratings, a 30–50 year material class, and a price that makes sense. Owens Corning Duration and comparable laminate shingles.

02

Designer and luxury shingles

Heavier profiles that imitate slate or cedar shake. Common on North Shore estates and historic homes where the roofline is the whole look.

03

Standing-seam and metal roofing

Long life, sheds snow, and holds up to salt air better than most alternatives on coastal and waterfront properties.

04

Flat and low-slope systems

TPO, EPDM rubber and modified bitumen for porch roofs, dormers, extensions and commercial decks.

Our process

How we run a roof replacement job

The same five steps on every job, whether it's a cracked pipe boot or a full tear-off.

Free on-site inspection

We walk the roof, check the attic and photograph what we find. You see the same pictures we do — including the parts of your roof you can't get to.

A written, itemized quote

One clear number, broken down by material and labor. No pressure, no vanishing discount that expires tonight, no surprise change orders halfway through.

Permits, materials, scheduling

We pull the town permits, order the material and give you a firm start date and a realistic finish date for the weather we're working in.

Installation by our own crew

Property gets tarped and protected before a single shingle comes off. Most residential roofs are torn off and re-roofed in one to two days.

Clean-up and final walkthrough

Magnet sweep for nails, debris hauled away, then we walk it with you before we ask for final payment and hand over your warranty paperwork.

FAQ

Roof Replacement — answered

How long does a roof replacement take?

Most Long Island single-family homes are torn off and completely re-roofed in one to two days. Larger homes, steep or cut-up rooflines, multiple layers of old shingle, or significant deck rot can push it to three or four. We give you a realistic window before we start, not an optimistic one.

Do I have to move out during the work?

No. You can stay in the house. It is loud — that part is unavoidable — so people working from home or with small children often plan around the tear-off day. We keep driveways clear when we can and always tell you the night before what the next day looks like.

Can you just go over my existing shingles?

We don't recommend it and we don't do it as standard. A layover hides rotten decking, adds dead load, traps heat against the new shingles and voids most manufacturer warranties. It saves money on day one and costs more the second time.

What does a new roof cost on Long Island?

It comes down to square footage, roof pitch, how cut-up the roofline is, how many old layers come off, how much decking needs replacing, and the shingle you choose. Anyone quoting you a number over the phone without seeing the roof is guessing. Our inspection and written quote are free.

What warranty comes with a new roof?

Shingles carry a manufacturer material warranty, and as an Owens Corning Preferred Contractor we can offer extended system warranties on qualifying installations. The exact coverage for your roof — materials and our workmanship — is written into your proposal before you sign it.

Will my homeowners insurance pay for it?

Insurance covers sudden damage — storm, wind, hail, a fallen tree — not gradual wear-out. If we think you have a claim, we document the damage with photos, meet your adjuster on the roof and make the case. If it's simply an old roof, we'll tell you that too.
