What Suffolk County Homeowners Say

Real reviews from Long Island homeowners.

Emergency call on a Sunday after a tree branch went through our roof. Someone was at our house within two hours with a tarp. The permanent repair was done that week.

Karen D.Smithtown, Long Island

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.

Mike R.Commack, Long Island

After the nor'easter damaged our roof, three different companies knocked on our door. Long Island Roofing Pros was the only one that didn't pressure us. They documented everything, helped with our insurance claim, and did the repair right.

Jennifer L.Long Beach, Long Island

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.

David S.Huntington, Long Island

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.

Patricia M.Levittown, Long Island

The salt air from the Sound had destroyed our flashing. They used stainless steel replacements and explained why that matters for waterfront homes. Five years later, still perfect.

Robert K.Northport, Long Island

New Roof Installation FAQ — Lake Grove

Answers to common questions from Long Island homeowners.

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.
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.
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).
