Roof Drain & Leader Clearing in NYC
Ponding roofs and overflowing leaders cleared before the ceiling tells you about it.
Roof drains swallow leaves, roofing debris, tennis balls and pigeon gifts, then feed into leader lines that clog exactly where you can't reach them. Left blocked, ponding water finds its way into the building — through the membrane, the parapet, or a tenant's ceiling.
We clear the drain bowl, rod or jet the leader line down to the house drain, and flow-test the whole run so you know the water is actually leaving the roof.
For buildings with a history of roof drainage problems, we run scheduled fall and spring clearings — the cheapest roof insurance there is.
