Vetted waterproofing specialists in Edenvale. Book now.

In Edenvale, waterproofing usually lands between R180 and R450 per m² depending on the system: liquid membranes at the lower end, torch-on at the higher end. A minimum charge applies to small jobs, and stripping or screed repairs are itemised. A written guarantee of five to ten years is normal for a full system.

Many Edenvale homes from the 1960s and 1970s have flat sections with several layers of old bitumen. If the slab is sound, stripping and applying a new system is usually cheaper than rebuilding. A specialist can check for slab cracks and decide.

Parapets are where most flat-roof leaks start, because the membrane changes direction and the wall cap often cracks. The fix is a proper upstand on the wall, a sealed or capped top and a correctly finished joint. Patching only the roof surface will not solve it.

On a flat roof in strong sun, usually yes. The reflective layer protects the membrane from UV, which is what makes bitumen go brittle, and it can noticeably cool the room below. It needs recoating every few years, so ask what the maintenance schedule looks like.
