Roof Waterproofing in Cape Town

What roof waterproofing involves

Roof waterproofing protects the roof surface and its penetrations - flashings, joints, parapets and roof penetrations - from water entering the structure below. On a flat or low-pitch roof this usually means a waterproofing membrane system; on a pitched roof it usually means sealing flashings, ridges and penetrations where leaks start.

Common roof waterproofing problems in Cape Town

Cape Town's winter rain exposes weak points quickly: cracked or perished membranes, flashing that has lifted, ponding water on flat roofs, blocked outlets, and old waterproofing that has simply reached the end of its life. A leak that only shows up during heavy rain is often a sign the waterproofing is failing at a specific point rather than across the whole roof.

Signs your roof may need waterproofing

Water stains on the ceiling, damp patches that appear after rain, peeling paint on ceilings, visible cracks or bubbling in an existing membrane, and ponding water that doesn't drain are all signs worth having assessed before the damage spreads.

Our approach

We assess the roof to find where water is actually entering - not just where it's showing up inside - then recommend a waterproofing approach suited to the roof type, condition and problem area. The affected area is prepared and waterproofed, with the goal of stopping the leak at its source rather than covering the symptom.
