Leak tracing
We follow the water back to where it entered, so we repair the cause, not the symptom.
Find the actual leak. Fix the actual cause.
Most roof leaks on Long Island are not holes in the shingles, they're failed flashing around chimneys, skylights, walls and pipe boots, or ice-dam backup at the eaves. Water enters at one point, runs along a rafter and drips through a ceiling somewhere else, which is why patching the stain rarely works. LaRocco Roofing & Siding traces the water to its actual entry point, repairs the cause and documents it with photos, so you see the same evidence we do. Typical repairs are step, chimney, sidewall and valley flashing redone in metal rather than sealant, pipe-boot replacement, shingle replacement and storm damage. We repair roofs throughout Long Island (Nassau County and Suffolk County) and Queens, NY, and we'll say plainly when a roof is too far gone to repair and replacement is the honest answer.
Water is a liar. It enters at one point, runs along a rafter, and drips through your ceiling fifteen feet away. That is why so many repairs fail, someone patched the ceiling stain instead of finding where the water actually got in.
We work back from where the water shows up to where it actually got in, then get on the roof and look at the thing that's really failing. Usually it's metal, not shingle: step flashing that was caulked instead of replaced, a chimney counter-flashing that pulled out of the mortar, a pipe boot whose rubber collar finally cracked in the sun.

Repairs at the eaves, plus the ventilation fix that stops it happening again.
Temporary protection to stop the damage while a permanent repair is scheduled.

If two or more of these sound like your house, book the free inspection. It costs nothing and it settles the question.
The same five steps on every job, whether it's a cracked pipe boot or a full tear-off.
We walk the roof and photograph what we find, then go through the pictures with you. You see exactly what we see, including the parts of your roof you can't get to.

Active leaks get priority. Call (516) 924-2050 and we'll get out to look as quickly as we can, often same or next day. If it's pouring and the ceiling is coming down, we can tarp the roof to stop the damage and come back to do the permanent repair properly.
Sometimes. A ten-year-old roof with one failed pipe boot is absolutely worth repairing. A twenty-two-year-old roof with curling shingles and its third leak this year is not, you'd be spending real money to postpone the inevitable by a season. We'll show you photos and tell you which one you have.
Because they fixed where the water appeared instead of where it entered. Water travels along rafters and sheathing before it drips. We trace it back to the actual entry point before repairing anything.
Yes. We photograph and document the damage, provide an itemized scope, and meet your adjuster on the roof so the two assessments are actually about the same thing. Sudden storm damage is usually covered; ordinary age and wear is not.
Yes, and often that's exactly the right answer. The honest caveat: new shingles rarely match twenty-year-old sun-faded ones perfectly, so a repaired section may be visible from the street. We'll show you where and let you decide.
No charge, no obligation, no high-pressure pitch. We look at the roof, send you the photos and tell you what it actually needs.
