YOUR QUESTIONS. ANSWERED.

Most residential roof replacements in Nassau and Suffolk County take 1–2 days. A standard 2,000 sq ft home is typically completed in a single day. Larger roofs, complex pitches, or homes requiring deck repairs may take 2–3 days. We work efficiently to minimize disruption to your family.

Roof replacement costs on Long Island typically range from $8,000 to $18,000 for a standard single-family home, depending on roof size, pitch, material chosen, and any deck repairs needed. Architectural shingles are the most popular choice. We provide free, detailed estimates with no obligation. If you have homeowners insurance, storm damage may be fully covered.

Yes — if your roof was damaged by a covered peril such as a nor'easter, hailstorm, wind damage, or fallen tree, your homeowners insurance will typically cover the replacement cost minus your deductible. Greene Group Construction works directly with all major insurers and handles the entire claims process for you, including documentation, adjuster meetings, and invoicing.

We install all major roofing systems including architectural asphalt shingles, impact-resistant shingles, cedar shake, flat roofing (TPO, EPDM, modified bitumen), and metal roofing. We use premium materials from manufacturers including GAF, CertainTeed, and Owens Corning, all backed by manufacturer warranties.

Signs you may need a full replacement: your roof is 20+ years old, you have widespread missing or curling shingles, granules are accumulating in gutters, you see water stains on ceilings, or there is sagging. Localized damage such as a few missing shingles, a flashing issue, or a small leak is often repairable. We provide free inspections and honest assessments — we will always tell you if a repair is sufficient.

Yes. Greene Group Construction provides free roof inspections throughout Nassau and Suffolk County. We assess your roof's condition, identify any damage, and provide a detailed written estimate. If your roof has storm damage, we document everything needed for an insurance claim at no charge.

Architectural asphalt shingles — the most common choice on Long Island — last 25–30 years under normal conditions. Impact-resistant shingles can last 30–40 years. Cedar shake typically lasts 20–30 years with proper maintenance. Metal roofing can last 50+ years. Long Island's nor'easters and coastal weather can accelerate wear, so proper installation with quality ice and water shield is critical.

Late spring through early fall (May through October) is ideal for roof replacement in Long Island due to mild temperatures and lower precipitation. However, we install roofs year-round. If you have storm damage, don't wait for ideal weather — a damaged roof left untreated will cause interior water damage. We tarp and protect your home until the full installation is complete.

We guarantee a 60-minute response time to water damage emergencies throughout Nassau and Suffolk County, 24 hours a day, 7 days a week, 365 days a year. Our crews are staged across Long Island to meet this commitment. When you call (631) 532-7346, a live dispatcher answers immediately and deploys the nearest available team.

Emergency water extraction typically takes 2–6 hours depending on the volume of water. Structural drying takes 3–5 days using industrial air movers and dehumidifiers. We monitor moisture levels daily and do not consider drying complete until readings return to pre-loss levels. Full reconstruction of damaged drywall, flooring, and finishes depends on the scope but typically takes 1–3 weeks.

It depends on the cause. Sudden and accidental water damage — burst pipes, appliance failures, roof leaks from storm damage — is typically covered by standard homeowners insurance. Flooding from groundwater or storm surge requires separate flood insurance (NFIP or private). Gradual leaks or neglected maintenance are generally not covered. We help you document your claim and work directly with your insurer to maximize your coverage.

Yes. Mold can begin growing within 24–48 hours of water exposure in the right conditions — and Long Island's humid climate accelerates this timeline. This is why immediate professional drying is critical. Our IICRC-certified technicians use industrial-grade dehumidifiers and air movers to dry your structure completely, and we apply antimicrobial treatments to prevent mold growth.

Hidden water damage signs include: musty or earthy odors, water stains or discoloration on walls or ceilings, peeling or bubbling paint, warped or buckled flooring, soft spots in walls or ceilings, and unexplained increases in your water bill. If you notice any of these, call us for a free moisture inspection — hidden water damage left untreated almost always leads to mold.

Yes. Sewage backups are a Category 3 biohazard requiring immediate professional response. Our crews use full personal protective equipment and EPA-approved disinfectants to safely remove sewage water, decontaminate all affected surfaces, and restore your home to safe living conditions. We also document the damage for your insurance claim.

First, ensure everyone is safe and do not re-enter the structure until cleared by the fire department. Call your insurance company to report the loss. Then call Greene Group Construction at (631) 532-7346 — we provide immediate emergency board-up and tarping to secure your home against weather and unauthorized entry. Do not attempt to clean soot or smoke damage yourself, as improper cleaning can cause permanent staining.

Smoke and soot penetrate deeply into walls, ceilings, HVAC systems, and contents. Our fire damage restoration process includes HEPA vacuuming of all soot, chemical sponge cleaning of all surfaces, thermal fogging, and industrial ozone and hydroxyl generator treatments to eliminate odors at the molecular level. We also clean or replace HVAC components to prevent smoke odors from recirculating.

Emergency board-up and securing of the structure happens within hours. Smoke and soot cleaning, odor treatment, and content pack-out typically take 1–2 weeks. Full structural reconstruction — rebuilding fire-damaged rooms, replacing drywall, flooring, cabinetry — can take 4–12 weeks depending on the severity. We give you a detailed timeline at the start of your project and keep you updated throughout.
