"Most roofs we're called to don't need replacing. They need one thing fixed properly, by someone who found the real source."
Most Brooklyn roof repairs cost between $450 and $2,500, and most leaks are not where the stain is. MLM Construction Group has repaired roofs on Brooklyn rowhouses, Bronx apartment buildings and Queens commercial properties since 2009 — flashing, seams, pipe boots, ponding drains and storm damage. Licensed, insured, BBB A+, with a 10-year workmanship warranty in writing.
Water travels. The stain on your ceiling is often several feet from where the water actually gets in, which is why so many "repairs" fail within a season — someone patched the stain instead of the source. We trace it properly before anyone opens a bucket of sealant.
Real 2026 ranges from jobs we actually run. Access, pitch and how much decking has rotted move these numbers more than anything else.
| Repair | Typical Brooklyn cost | When it applies |
|---|---|---|
| Pipe boot / vent collar reseal | $450 – $850 | Cracked rubber collar around a vent — the most common leak we find |
| Flashing repair (wall, chimney, skylight) | $600 – $1,600 | Water entering at a joint between roof and something vertical |
| Flat roof seam or patch | $700 – $1,800 | Open seam, blister or puncture in EPDM, TPO or modified bitumen |
| Ponding water / drain correction | $900 – $2,500 | Water sitting 48+ hours after rain; tapered insulation or a new drain |
| Shingle section replacement | $550 – $1,500 | Wind-lifted or missing shingles over a defined area |
| Deck / structural repair | $2,500 + | Sheathing has gone soft — priced after the roof is opened |
| Emergency dry-in (temporary) | $350 – $700 | Stops the water tonight; credited toward the permanent repair |
