Leaking flat roofs after the first winter fronts
Flat roofs and box gutters are common on Kleinmond houses. When an outlet blocks with leaves or sand, water ponds and finds every tired lap and crack. The first north-westers of winter are usually when the stains appear.
We clear and correct outlets, open and re-seal failed laps, and waterproof the roof with a torch-on or liquid-applied system suited to it.
