Find the failed detail and the extent of the leak

Water entering at a rooftop curb or seam can move through insulation before showing up inside. Multiple stains do not always mean multiple openings. We assess the roof field, seams, penetrations, wall flashings and drainage connected to the affected area.

The covering system guides the repair method. Welded thermoplastic seams, EPDM tape details and coated substrates require different preparation and compatible materials. A generic bucket-applied patch is not a substitute for identifying the roof.

A repair must connect to sound material

Surface defect

A puncture or localized failed seam can be repaired where the surrounding membrane is sound and can accept the specified connection. Cleaning and preparation affect that bond.

Wet assembly

Moisture in insulation or damage to the deck can require opening and replacing affected layers before the surface is restored. The stain does not measure that boundary.

Drain or equipment detail

A drain connection, curb flashing or perimeter termination needs its own rebuilt detail. Work around equipment also needs safe access and coordination with the building’s use.

Put the occupied building in the work plan

Tell us what is below the leak, whether water is entering now and how the building is used. Tenant entrances, stored goods, loading areas and rooftop service routes affect staging and temporary protection.

If the roof has repeated failures or widespread moisture, we explain replacement or a suitable restoration alongside the repair. A local patch should solve a local defect; it should not be presented as renewing the entire roof.
