A roof does not always fail suddenly. Waterproofing problems can develop gradually as coatings age, cracks open, details deteriorate or water begins to collect where it should drain away.
Recurring leaks after rain
If water appears inside after rainfall, the roof is an obvious area to investigate. The visible damp mark is not always directly below the entry point, so diagnosis should consider the wider roof and building details.
Cracks in the roof surface or parapets
Cracks do not all have the same cause or significance. Some may be limited to surface coatings while others may involve the substrate or junctions. They should be assessed before simply covering them with another layer.
Peeling, blistered or visibly failed coatings
Old waterproofing materials can lose adhesion or develop splits and blisters. New work needs a sound, compatible base, which may mean removing loose material or preparing the existing layer carefully.
Ponding water
Water that remains on a flat roof after rain deserves attention. Waterproofing should not be used as a substitute for sensible drainage, and persistent ponding can put additional demand on roof details.
Damp marks inside the property
Ceiling or upper-wall staining can be associated with roof ingress, but condensation and plumbing problems can create similar symptoms. Our damp and moisture service focuses on understanding the source before recommending treatment.
What should happen before waterproofing?
A good process includes inspection, cleaning, preparation of cracks and details, assessment of previous systems and selection of a compatible waterproofing method. Read more in our guide to preparing a roof before waterproofing.
