There is a drip in the upstairs closet that only shows up in a hard rain from the east. The roofer who comes out will charge for the visit, the fix and whatever they find once the shingles are up, and most of that can be priced before anyone climbs the ladder.

Tom Jannace Roofing in Stony Brook breaks a shingle repair down to the piece: $25 to $45 of labor per shingle, plus $3 to $8 for a standard three-tab shingle or $8 to $15 for architectural, and a $75 to $150 service call that is often waived if the repair goes ahead. It adds that needing more than 20 shingles suggests a bigger problem worth a full look.
Flashing, pipe boots and vents
When the shingles are intact, the leak is often at something that goes through the roof.

Chimney flashing has the widest spread because “reseal the gaps” and “tear out and replace the step and counterflashing” are very different jobs. Home Team Construction puts chimney flashing repair at $300 to $1,800 depending on access and damage. Ask which one the quote is for. Our chimney repair page covers the masonry side.

Skyscape Roofing says emergency jobs cost 20 to 35 percent more than scheduled repairs. If it is an insurance claim, New York’s Department of Financial Services says to save every receipt for temporary fixes and not to make permanent repairs until the insurer has inspected. Our emergency roof repair page has the first-hour checklist.
Rot and decking under the shingles
The number nobody can give you until the shingles come off is rotted plywood. Aaron Roofing lists structural decking at $200 to $500 a sheet on a repair, and All American Home Improvement says minor decking repairs run $500 to $1,500. On a full reroof, LI Roofing Co. says rotted decking or sheathing replacement adds $800 to $3,000 depending on the extent, and that it photographs the damage and gets approval before any extra work. Get the per-sheet price in writing before work starts.
Hourly rates behind the numbers
Skyscape Roofing puts roofing labor at $60 to $95 an hour in Nassau and $50 to $85 in Suffolk. All American Home Improvement says basic repairs run $50 to $120 an hour. A repair quote may come as one flat price, but those rates explain why a two-hour job on a steep two-story roof costs more than the same fix on a ranch.
When patching stops making sense
LI Roofing Co. gives the clearest rule: if the repair is under 15 percent of what a new roof would cost, repair it. Between 15 and 30 percent is a judgment call, and over 30 percent, replacement almost always wins. By age, it says repair almost always makes sense under 10 years, and at 15 to 20 years only if the repair buys 3 to 5 more years for under 25 percent of replacement. Skyscape Roofing says a roof under 15 years old with damage in one area is usually a repair.
Insurance can tip the decision on an older roof. Rapid Roofing says some policies now reduce coverage once roofs pass 15 to 20 years, and that insurers will likely treat age-related breakdown on a 22-year-old roof as maintenance, not storm damage. Our roof replacement cost guide has the other side of the math.
