Commercial Roof Leaking?
Water inside the building tells you there is a problem; it does not tell you which roof detail has failed. The first job is to work out the roof type, the likely ingress routes and whether the issue is local or part of wider deterioration.
Start with the roof type
A metal roof, asbestos-cement roof, EPDM membrane, liquid-applied roof and box gutter do not fail in the same way. Treating every commercial leak as one generic flat-roof problem is how the wrong repair gets specified.
Profiled metal roof
Check fixings and washers, side and end laps, cut edges, flashings, rooflights, penetrations, gutters and whether condensation is being mistaken for external ingress.
Read the problem guideAsbestos-cement roof
The leak source and the condition of the asbestos-containing material both matter. Laps, fixings, cracks, rooflight interfaces and weathered sheets are assessed without assuming repair, encapsulation or removal in advance.
Read the problem guideFlat membrane or liquid-applied roof
Upstands, outlets, penetrations, seams, local membrane damage, ponding and the condition of the existing build-up all change the repair or refurbishment route.
Read the problem guideEPDM roof
Punctures, seams, perimeter details, outlets and penetrations should be checked before deciding whether a local repair or wider membrane work is needed.
Read the problem guideCommercial gutter or box gutter
Water entering the building can originate from failed gutter joints, corrosion, outlets, lining defects, poor falls or overflow rather than the roof covering itself.
Read the problem guideWhat helps narrow the leak down
A useful first assessment is about evidence, not guessing from the stain on the ceiling. Photographs, the timing of the leak and what is happening on the roof all help narrow the likely route.
Repair, wider refurbishment or replacement?
An isolated failed detail may only need a local repair. Several recurring leaks, widespread corrosion or coating failure, extensive membrane deterioration or a compromised roof build-up can point towards a wider refurbishment. Replacement is considered where the existing roof cannot provide a suitable basis for repair or refurbishment.
The important point is that the response follows what is found. We do not need you to choose the system before you contact us.
