Fast, lasting roof leak repairs and shingle repairs by Long Island's trusted roofing company. We fix it right the first time. Nassau and Suffolk County. Emergency service available.
Not every roof problem requires a full replacement. Greene Group's experienced roofing crews diagnose the exact source of your leak or damage and make precise, lasting repairs that extend the life of your roof and protect your home.
We repair all types of roofing issues — from a handful of missing shingles after a windstorm to complex multi-point leaks caused by failed flashing, cracked pipe boots, or damaged valleys. Every repair starts with a thorough inspection to ensure we identify all problem areas, not just the obvious ones.
Experiencing an active leak? We offer emergency tarping and temporary protection to stop water intrusion immediately, followed by a permanent repair. We also handle all insurance documentation for storm-related repairs.
Wind frequently blows shingles off Long Island roofs. We replace them with closely matched materials and seal surrounding areas to prevent water entry.
Failed flashing around chimneys, skylights, walls, and valleys is the #1 cause of roof leaks. We replace flashing properly using the correct materials for your roof type.
Roof valleys collect heavy water flow. When valley material fails, leaks develop. We re-flash and reshingle valleys for a permanent fix.
Rubber pipe collars crack and shrink over time, creating leaks around plumbing vents. We replace pipe boots quickly — one of the most common and overlooked leak sources.
Nails that back out lift shingles and create entry points for water. We re-secure lifted shingles and reseal the affected area.
EPDM and TPO flat roofs develop blisters, cracks, and seam failures. We patch or replace affected areas to restore waterproof integrity.
