Emergency Commercial Flat Roof Leak Repairs
A flat-roof leak over an occupied commercial floor needs a survey and a make-safe the same instruction — not a domestic roofer and not a scaffold that closes the building.

This page is for emergency flat-roof leaks on occupied commercial buildings. We survey the roof and its interfaces, make the leak safe, and complete a permanent commercial repair. Offices, hotels, restaurants and live trading floors stay in use.
It is not a domestic roofing offer. If the leak is in curtain wall or overhead glass rather than the flat roof build-up, use glass leak repairs or glazing leak detection.
The wider access-led roof offer — roof lights and high-level weathering as well as leaks — is commercial roof repairs. Where an aerial look is the sensible first step, see drone building surveys. Glazed roofs and atriums are atrium and rooflight glazing; historic roof lanterns are heritage glazing.
