General
What areas does LaRocco Roofing & Siding serve?
We serve all of Long Island — Nassau County and Suffolk County — plus Queens, NY. We're based at 17 Angela Lane, Bay Shore, NY 11706.
Are estimates really free?
Yes. Inspections and written estimates cost nothing and carry no obligation. You get photos of your roof and an itemized quote whether or not you hire us.
How long has LaRocco Roofing & Siding been in business?
More than 15 years working on Long Island roofs, siding and gutters, residential and commercial.
Are you licensed and insured?
Yes. We carry the licensing and insurance required for the towns we work in, and we'll send current certificates before work starts. We're also an EPA Lead-Safe Certified Firm, which is required for exterior work on pre-1978 homes.
Do you offer financing?
Yes. We partner with Hearth, so you can check monthly payment options without affecting your credit score before you commit to anything.
What roofing materials do you install?
Architectural and designer asphalt shingles, standing-seam and metal roofing, and flat-roof systems including TPO, EPDM rubber and modified bitumen. We're an Owens Corning Preferred Contractor.
Do you handle insurance claims for storm damage?
Yes. We document damage with photographs, provide an itemized scope of work and meet your adjuster on the roof so both assessments are based on the same evidence.
How soon can you start?
Free inspections are usually within a few days. Active leaks and storm damage get priority — call (516) 924-2050. Full replacements are scheduled around permits, material lead time and weather, and we give you a realistic date rather than an optimistic one.
Do you replace the roof deck if it's rotten?
Yes, and we show you before we do. Rotted or delaminated plywood is replaced before the new roof goes on — you approve the sheet count, so there's no surprise line on the invoice.
Who will actually be doing the work?
Our own crew, with owner Peter LaRocco on site. We don't hand residential roofing to a rotating cast of subcontractors.
Roof Replacement
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.
Roof Repair
How fast can you get here for a leak?
Active leaks get priority. Call (516) 924-2050 and we'll get out to look as quickly as we can — often same or next day. If it's pouring and the ceiling is coming down, we can tarp the roof to stop the damage and come back to do the permanent repair properly.
Is it worth repairing an old roof?
Sometimes. A ten-year-old roof with one failed pipe boot is absolutely worth repairing. A twenty-two-year-old roof with curling shingles and its third leak this year is not — you'd be spending real money to postpone the inevitable by a season. We'll show you photos and tell you which one you have.
Why does my roof still leak after someone repaired it?
Because they fixed where the water appeared instead of where it entered. Water travels along rafters and sheathing before it drips. We diagnose from the attic first so we're repairing the actual entry point.
Do you handle insurance claims for storm damage?
Yes. We photograph and document the damage, provide an itemized scope, and meet your adjuster on the roof so the two assessments are actually about the same thing. Sudden storm damage is usually covered; ordinary age and wear is not.
Can you repair just one section of the roof?
Yes, and often that's exactly the right answer. The honest caveat: new shingles rarely match twenty-year-old sun-faded ones perfectly, so a repaired section may be visible from the street. We'll show you where and let you decide.
New Roof Installation
What's the difference between installation and replacement?
Replacement means there's an existing roof to tear off first. Installation means there isn't — new construction, a fresh addition, a new dormer or a garage. The roof system itself goes on the same way; replacement just adds the demolition and disposal.
Do you work with general contractors and builders?
Yes. We work as the roofing trade on new builds and large renovations, and we schedule around the framing and dry-in dates rather than making your GC chase us.
Which shingle should I choose?
For most Long Island homes an architectural asphalt shingle is the right balance of wind rating, lifespan and cost. Designer profiles make sense on historic or high-visibility rooflines. On the coast, metal is worth a serious look. We'll bring samples and show you what's on your neighbors' roofs.
How important is attic ventilation really?
Genuinely important, and routinely ignored. Without balanced intake at the soffit and exhaust at the ridge, summer attic heat bakes the shingles from below and winter moisture condenses on the sheathing. It shortens roof life and most manufacturers make proper ventilation a warranty condition.
Roof Inspection
Is the roof inspection really free?
Yes — free, and with no obligation. We'd rather be the company you call in four years when the roof genuinely needs replacing than the one that pressured you into it today.
How often should a roof be inspected?
Once a year is sensible on Long Island, plus after any major storm. Older roofs and homes under big trees benefit from spring and fall checks.
Do you inspect roofs for a home purchase?
Yes. Buyers and sellers both ask us to assess a roof's condition and remaining life before closing. It's a common negotiating point and worth knowing before you sign.
Will you tell me my roof is fine if it is?
Yes, and we do it regularly. A large share of inspections end with 'you've got years left, clean your gutters, call us in the spring.' That's the whole business model.
Roof Maintenance
How often does a roof need maintenance?
Annually for most Long Island homes, and after any major storm. Homes under heavy tree cover or near the water benefit from twice a year — salt air and constant debris are both hard on a roof.
Does maintenance really extend roof life?
Yes. The failures that kill roofs early are small and local: a cracked pipe boot, a lifted shingle, a valley packed with wet leaves, blocked soffit vents. All are cheap to fix and expensive to ignore.
Is maintenance worth it on an older roof?
If the roof has real life left, absolutely. If it's already past its service life and leaking in multiple places, maintenance is just money spent delaying a replacement — and we'll say so rather than sell you a plan.
Do you offer maintenance agreements?
Yes — call us and we'll set up a recurring annual visit so you don't have to remember it. It's especially worth doing on commercial and multi-family properties.
Commercial Roofing
Can you work outside our business hours?
Yes. Retail and restaurant clients usually want us there early, late or at weekends, and we schedule that way. We also stage material and dumpsters to keep access and parking usable.
TPO or EPDM — which is better?
TPO's white reflective surface cuts cooling load and it's heat-welded at the seams, which is why it dominates new commercial work. EPDM is proven, flexible and often easier on roofs with lots of penetrations. Deck condition, roof traffic and budget decide it — we'll walk the roof and recommend.
Do you provide documentation for property managers?
Yes — itemized scopes of work, photo condition reports and maintenance records suitable for boards, owners and insurers.
Can a flat roof be restored instead of replaced?
Often, yes. If the deck and insulation are dry and the membrane is intact, a coating or restoration system can add years for a fraction of a tear-off. If there's trapped moisture in the insulation, it can't — a core sample tells us which.
Siding Installation
How long does a siding job take?
A typical Long Island home takes roughly three to seven working days depending on size, how much trim and detail there is, and whether we find sheathing to repair once the old siding comes off. Weather moves it; we keep you posted.
Can you side over the existing siding?
We advise against it. Going over the top means nobody inspects the sheathing, the house wrap never gets corrected and any hidden rot keeps rotting. Removing the old siding is how you find out what you're actually dealing with.
Which siding is best near the water?
Fiber cement and heavier-gauge vinyl both do well in salt air. Aluminum corrodes over time on exposed waterfront elevations. Whatever the material, the fastening schedule and flashing details matter more than the brochure.
Will new siding lower my energy bills?
Insulated vinyl and adding continuous insulation under new siding both help, and sealing the air leaks we find behind the old siding often helps more. It's a real improvement, not a miracle — anyone promising you a halved heating bill is selling.
Do you replace trim, soffit and fascia too?
Yes, and we usually should. New siding against tired, rotting trim looks half-finished and leaves the actual water problem in place.
Siding Repair
Can you match my existing siding color?
Sometimes closely, rarely perfectly. Vinyl fades with UV exposure and manufacturers discontinue profiles. Where we can't match, we sometimes pull panels from a less visible elevation — a rear or garage wall — and put the new ones there instead.
Is siding damage covered by insurance?
Sudden damage from storm, wind or impact usually is. Gradual wear, fading and old age aren't. We photograph and document the damage properly so the claim is assessed on evidence.
When is repair no longer the right call?
When damage is spread across multiple elevations, when the siding is brittle enough that removing one panel breaks the next, or when we keep finding wet sheathing. At that point repairs become a series of payments toward a replacement you're going to do anyway.
Do you repair siding you didn't install?
Yes, routinely — most of our siding repair work is on homes sided by someone else years ago.
Gutter Installation
Are seamless gutters worth it over sectional?
Yes. Sectional gutters leak at the joints — that's simply where the seams are, and sealant there is a consumable. Seamless gutters are formed on site to the full run length, so the only joints are corners and outlets, which we seal properly.
5-inch or 6-inch gutters?
5-inch handles most Long Island homes. Go to 6-inch on large or steep roof areas, on homes with big roof planes draining to a single run, or anywhere the existing gutters overflow in heavy rain despite being clear.
Do gutter guards actually work?
Good ones dramatically cut how often you clean, particularly under oaks and pines. None are truly maintenance-free — fine grit and pine needles still need occasional attention. Treat 'never clean your gutters again' as marketing.
How do gutters cause ice dams?
They don't cause them, but clogged gutters make them much worse. Ice dams come from attic heat melting snow that refreezes at the cold eave. Ventilation and insulation are the real fix; clear gutters and ice-and-water shield underneath limit the damage.
Can you install gutters without replacing my roof?
Yes. Gutters are a standalone job. Doing them at the same time as a roof replacement is more efficient, but it's not required.
Long Island
What areas of Long Island do you serve?
All of Nassau County and Suffolk County, plus Queens. We're based at 17 Angela Lane in Bay Shore, which puts us central to the South Shore and within easy reach of the North Shore, the East End and the Queens border. If you're not sure whether you're in range, call (516) 924-2050 and ask.
Are you licensed and insured on Long Island?
Yes — we carry the licensing and insurance required to work in the towns we serve, and we're happy to send current certificates before work begins. We're also an EPA Lead-Safe Certified Firm, which matters on Long Island's large pre-1978 housing stock.
How quickly can you get to my house?
Free inspections are usually scheduled within a few days. Active leaks and storm damage get priority — call and we'll get out as fast as we can, and tarp the roof if it needs protecting before a permanent repair.
Do you handle town permits?
Yes. Long Island's towns and incorporated villages each have their own requirements and we pull the permits and meet the inspector as part of the job.
Nassau County
Which Nassau County towns do you cover?
All of them. We regularly work in Garden City, Great Neck, Hempstead, Mineola, Massapequa, Manhasset, Port Washington, Levittown, Freeport, Rockville Centre, Long Beach, Valley Stream, Bethpage, Westbury, Hicksville, Glen Cove, Syosset, Wantagh, Merrick, Baldwin, Oyster Bay and the surrounding communities.
Do you pull permits for Nassau County villages?
Yes. Each incorporated village has its own requirements and we handle the permit application and inspection as part of the job.
How far in advance should I book a roof replacement?
Spring and fall are the busy seasons across Nassau. If your roof is failing but not leaking, booking a few weeks out gets you a better slot and better weather. Emergencies jump the queue.
Suffolk County
Where in Suffolk County are you based?
17 Angela Lane, Bay Shore, NY 11706. It's central to the South Shore and puts most of Suffolk within a comfortable drive.
Do you work on the East End?
Yes — Riverhead, Southampton, East Hampton, Montauk and the surrounding communities. Coastal exposure out there changes what we recommend for materials and fastening, and we'll explain why during the inspection.
Which Suffolk towns do you serve most often?
Bay Shore, Babylon, Islip, West Islip, East Islip, Lindenhurst, Copiague, Amityville, Deer Park, Brentwood, Commack, Hauppauge, Smithtown, Huntington, Melville, Northport, Kings Park, Stony Brook, Port Jefferson, Patchogue, Sayville, Bohemia, Holbrook, Ronkonkoma, Medford, Selden, Centereach and Lake Grove.
Can you come out same day for a leak in Suffolk?
Often, yes — being local is the whole advantage. Call (516) 924-2050 and we'll tell you honestly when we can be there.
Queens
Do you work throughout Queens?
Yes — Astoria, Long Island City, Flushing, Jamaica, Forest Hills, Bayside, Whitestone, Ridgewood, Sunnyside, Woodside, Elmhurst, Jackson Heights, Rego Park, Kew Gardens, Richmond Hill, Ozone Park, Howard Beach, Douglaston, Little Neck, College Point, Maspeth, Middle Village, Glendale, Fresh Meadows and the surrounding neighborhoods.
Do you do flat roofs in Queens?
Yes, and it's a large share of our Queens work. TPO, EPDM rubber and modified bitumen systems, plus drains, scuppers and parapet detailing.
How do you handle attached houses?
Carefully. Party walls and shared parapets need the flashing and termination detailed properly on both sides, and we talk to the neighbor before we start rather than after something goes wrong.
Where do you put the dumpster on a narrow street?
We plan it before the job — permits where required, placement agreed with you, and staged so access and parking stay workable.
