Roof Replacement Reviews from Long Island Homeowners
Real reviews from Long Island homeowners.
“They replaced our entire roof in one day. The crew showed up at 7:30 AM sharp and by 3:30 PM they were sweeping the yard with magnets for stray nails. Couldn't believe how fast and clean they were.”
“We got four quotes for our colonial's roof replacement. Long Island Roofing Pros was the only company whose estimate included a line-by-line breakdown of materials, labor, and permit costs. No surprises on the final bill.”
“Our 1952 Cape Cod in Levittown needed a full tear-off. They found rotted decking that three other roofers missed during their inspections. Honest, thorough, and fair price.”
“I was terrified of getting scammed after hearing horror stories from neighbors. They gave us their HIC license number upfront, showed us their insurance certificates, and pulled the permit themselves. Total peace of mind.”
“Our split-level has four different roof planes and nobody wanted to give us a straight answer on cost. These guys walked us through each section, explained the valleys and transitions, and priced it fairly.”
“After Sandy, we swore we'd only use a local, licensed company for roof work. Long Island Roofing Pros checked every box. Nassau HIC licensed, insured, GAF certified, and they actually live on the Island.”
Roof Replacement FAQ
Answers to common questions from Long Island homeowners.
Most Long Island homeowners pay between $9,000 and $18,000 for an asphalt shingle roof replacement. The exact cost depends on roof size, material choice, pitch complexity, and your town's permit fees. Long Island pricing runs 15-25% above the national average due to higher labor rates and material delivery costs.
Yes. Both Nassau and Suffolk counties require building permits for full roof replacements, tear-offs, and structural modifications. In Nassau, permits are handled by your town (Hempstead, North Hempstead, or Oyster Bay). In Suffolk, each of the 10 towns has its own building department. Minor repairs (a few shingles) are generally exempt.
Asphalt shingle roofs typically last 15-25 years on Long Island — shorter than the national average of 20-30 years due to salt air exposure, nor'easter winds, and freeze-thaw cycles. Metal roofs can last 40-70 years. Slate roofs on older North Shore homes can last 75-100+ years with proper maintenance.
Insurance typically covers roof damage caused by sudden events like storms, fallen trees, or fire — but not normal wear and aging. After storm damage, document everything with photos before making temporary repairs, then file your claim promptly. We help Long Island homeowners navigate the insurance claim process.
For most Long Island homes, architectural asphalt shingles offer the best balance of cost, durability, and wind resistance. For coastal homes (South Shore, Hamptons), metal roofing handles salt air and high winds better. Premium options like CertainTeed, GAF, and Owens Corning are all excellent choices rated for Long Island's climate zone.
Verify their Nassau or Suffolk County HIC license, check for workers' comp and general liability insurance ($500K+ minimum), look for manufacturer certifications (GAF, Owens Corning), read recent reviews (Google, HomeAdvisor), get 3 written estimates, and confirm they pull permits. Avoid door-to-door storm chasers.
Missing or curling shingles, granules in gutters, daylight visible through attic boards, water stains on ceilings, sagging roof deck, moss or algae growth, and your roof is 20+ years old. If you notice any of these, schedule a free inspection.
Most residential roof replacements take 1-3 days depending on roof size, weather, and complexity. A standard ranch or Cape Cod can often be completed in a single day. Colonials and multi-level homes with complex rooflines typically take 2-3 days.
Yes, but it's not ideal. Asphalt shingles need temperatures above 40°F to seal properly. Winter installations may require hand-sealing. The trade-off is potentially lower pricing and faster scheduling during the off-season (December-February).
Yes. Salt air accelerates corrosion of metal flashings, fasteners, and drip edges. It also causes faster granule loss on asphalt shingles. Homes within 2 miles of the coast (South Shore, barrier islands, North Shore waterfront) may see roof lifespans reduced by 20-30%.
GAF is the largest roofing manufacturer in North America. Certified contractors meet GAF's standards for proper licensing, insurance, and installation training. Master Elite contractors (only 2% nationwide) can offer GAF's best warranties. It's one of the strongest trust signals in the roofing industry.
For coastal homes, absolutely. Metal roofs handle salt air, high winds (rated 140+ mph), and snow loads far better than asphalt. They last 40-70 years vs 15-25 for asphalt near the coast. The higher upfront cost ($15K-$54K) pays off in longevity and lower maintenance.
Are you licensed in Nassau/Suffolk County? What's your HIC license number? Do you carry workers' comp? Will you pull the building permit? What manufacturer certifications do you hold? Do you offer written warranties on labor? Can I see recent local references? Will you provide a written estimate with line items?
Improve attic insulation to R-49 (current code requirement), ensure proper soffit and ridge ventilation, seal air leaks around bathroom fans, light fixtures, and attic hatches, and consider installing ice and water shield membrane along eaves during your next replacement.
Late spring and early fall offer the best balance of weather and scheduling. Summer (July-September) is peak season with longer wait times and potentially higher prices. Late fall/winter offers the best pricing but weather can delay work.
Yes. Both Nassau and Suffolk counties require a Home Improvement Contractor (HIC) license. Nassau requires fingerprinting; Suffolk requires passing a 25-question exam and $200 fee. Always verify a contractor's license before hiring.
Building codes generally allow one layer of new shingles over old, but we don't recommend it. Layering hides damage to the decking, adds weight, traps heat (shortening shingle life), and can void manufacturer warranties. A proper tear-off is always the better investment.
If damage is localized (a few missing shingles, one leak point) and your roof is under 15 years old, repair is likely sufficient. If damage is widespread, you're seeing granules in gutters, multiple leaks exist, or your roof is 20+ years old, replacement is the better investment.
Consequences include stop-work orders, double permit fees, failed home inspections when selling, potential insurance claim denials, and legal liability. Unpermitted work can also be a deal-breaker for home buyers and their lenders.
Yes. Architectural (dimensional) shingles cost only 10-20% more than 3-tab but last 25-30 years vs 15-20, offer better wind resistance (rated 110-130 mph vs 60-70 mph), and significantly improve curb appeal. They're the standard choice for Long Island replacements.
Manufacturer warranty (25-50 years on materials), workmanship warranty from your contractor (5-15 years on labor), and potentially an extended system warranty if your contractor is manufacturer-certified (e.g., GAF Golden Pledge covers both materials and labor for 25-50 years).
Long Island's unique combination of nor'easters (high winds + driving rain), salt air corrosion, freeze-thaw cycling (60-80 times per year), hurricane exposure, and heavy wet snow creates more stress on roofing materials than typical inland areas. This is why roofs last 20-30% shorter on Long Island and why choosing the right materials and contractor matters more.
