Atlantic finds where water gets in, where it already sits, and what is buried before you dig — for owners, architects and contractors across Greater New York and New England.

Water is showing up and nobody agrees where it comes from. We find the breach to the square inch.
Find The Leak →A new membrane, an AVB, a warranty condition. Tested and documented before sign-off, without a flood test.
Certify The Work →Utilities, slab interiors, water mains — located and marked before the excavator or the core drill arrives.
Scan The Site →The breach, to the square inch. No flooding, no waiting for rain.
The whole roof read for hidden moisture after sunset.
Through ballast and overlay, in any weather.
Proven while it is still exposed, and correctable.
What is buried before you dig; what is in the slab before you cut.
Breaks located from the surface, without excavation.
Infrared and nuclear both, FM approved methods, licensed operators — so nothing rides on the answer but the truth.
Electronic Leak DetectionLow-voltage vector mapping finds where water gets through a membrane without flooding the roof or waiting for rain — and certifies new membranes before sign-off.
Moisture SurveysInfrared reads the whole roof after sunset, when wet insulation gives itself away. Nuclear reads through ballast and overlay in any weather. We carry both, so the method fits the roof — not our inventory.
Air & Vapor BarrierThe barrier tested while it is still exposed — before the cladding hides it for good and every fix costs ten times more.

Their scope language went straight into our spec, and the qualification package came the same day.
