Get a Green Point QuoteRecurring Issues in Green Point
- Roof terraces. Trafficked decks over living space. The membrane sits under the finish and the door threshold is where it usually fails.
- Salt on fixings. Screws, brackets and balustrade bolts corrode well before the surfaces around them.
- Wind uplift. Exposed positions work fixings loose over time, and a loose fixing leaks long before it looks like a problem.
- Older flat roofs. Layers of coating built up over decades, often over falls that no longer drain.
- Mixed ownership. Converted buildings where roof responsibility is split between units.
What the Buildings Are Like
Mid-rise apartment blocks and converted semis, with a mix of concrete flat roofs, small pitched roofs and a large stock of exposed balconies and roof terraces.
Roof terraces are effectively trafficked flat roofs and should be specified as such. A coating chosen for a roof nobody walks on will not survive furniture and foot traffic.

Budget ranges only, not a quotation. Drawn from published South African waterproofing and roofing pricing so you have a starting point before anyone visits.
Ask what each rate includes. A cheap rate that excludes stripping and preparation is not cheaper.
Compare three quotes on specification rather than on the total alone.

Frequently Asked Questions
Can a roof terrace be waterproofed without lifting the tiles?
Only where the membrane below is sound and the problem is limited to grout or sealant. Where the membrane has failed, the finish has to come up.
How often should coastal roof fixings be checked?
Annually is reasonable this close to the sea. Backed-out or rusted screws are cheap to replace and expensive to ignore.
Who is responsible for roof work in a complex or sectional title scheme?
Normally the body corporate for common property, instructed by the trustees or managing agent. Exclusive-use areas such as balconies depend on the scheme's rules, so confirm before commissioning anything.
Is the cheapest waterproofing quote usually the right one?
Rarely. The cheapest quote is typically the one that coats over the existing membrane, prices preparation as a variation and excludes making good. Compare the inclusions before comparing the totals.
How much does waterproofing cost in Green Point?
Roof waterproofing generally runs R150 to R350 per square metre, with torch-on membrane at R300 to R400. A 40 m² flat roof typically lands between R12,000 and R24,000. Damp treatment on a single wall usually totals R6,000 to R18,000.
How do I compare waterproofing quotes for a property in Green Point?
Compare the specification rather than the total. Which system, how many coats or layers, what preparation is included, how upstands and outlets are detailed, and what the guarantee excludes. Two quotes far apart usually differ on stripping and preparation.
