Most leaks are not where the water lands
Water travels. It enters at a failed detail, runs along the deck or through the insulation, and shows up at the first place the assembly lets it down — often many feet from the actual breach. Diagnosis is the job; patching is the easy part.
The details that fail first are almost always the same: base flashings, curbs and penetrations, terminations at parapets and walls, drains and scuppers, and laps that were never properly rolled.
What we repair
- Built-up, modified bitumen, single-ply and metal roof systems
- Flashings, curbs, pipe penetrations and equipment supports
- Parapet walls, copings and terminations
- Drains, scuppers and ponding correction
- Sheet metal detail work by our own mechanics
Before we get there
Move what you can out from under the drip. Set containers, not tarps, under an active leak — a tarp spreads water across ceiling tile. Photograph the interior staining and note the time relative to the rain. If it's safe, note whether the leak starts with the rain or an hour into it; a delayed leak usually means saturated insulation rather than an open hole.
Do not send anyone onto a wet commercial roof.
