Long Island homeowners face these roof issues most often — we fix them all
Wind frequently blows shingles off Long Island roofs. We replace missing shingles 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 or shingles shift, 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.
When repairs aren't enough, we handle complete replacements too
