Leak repair
Find the entry first
Water on a flat-roofed building travels along the deck, down the inside of a wall and out through a ceiling far from the hole. We trace it before we price a repair, so the repair goes where the water gets in.
We work set hours: Monday to Friday, 7 to 5, and Saturday morning. Call or text and we tell you the first opening.

Questions
Before you call
Why is there a stain in my top-floor ceiling when the roof looks fine?
Water travels. On a flat roof it often enters at the parapet, the coping or the wall flashing, runs down inside the wall, and shows up a floor or two away. We trace it before we price a repair.
Will you work with my insurance?
You decide whether to file a claim, and you deal with your insurer. We inspect, photograph and write an itemized estimate you can share with them. The deductible stays with you, and we are not public adjusters.
Do you repair slate and tile?
On porch, bay and mansard roofs, yes: we repair and re-lay to match what is there. We do not re-lay whole slate roofs; we will say so at the visit and tell you who does.
A stain on the ceiling?
Tell us where it is and what floor. We take it from there.
