How flat roofs Fail

Flat roofs are exposed to constant sun, rain and movement. Over time small issues become big leaks.

These issues often work together, which is why a flat roof should be assessed as a full system rather than patched only where water appears inside.

Flat Roof Waterproofing Systems We May Use

FAQ

Flat Roof Waterproofing Johannesburg Questions & Answers

How do I know whether my flat roof needs a repair or a full waterproofing system?

If the problem is isolated to one outlet, skylight, crack or wall junction, a targeted flat roof leak repair Johannesburg solution may be enough. If the roof has widespread failed membranes, ponding water, weak substrate or repeat leaks, a full flat roof waterproofing system may be more reliable.

Ponding water is usually caused by poor falls, blocked outlets, surface dips, old waterproofing build-up or drainage that no longer moves water away properly. A ponding water flat roof repair should focus on why water is sitting there before any flat concrete roof waterproofing system is applied.

Sometimes, but not always. For proper roof slab waterproofing Johannesburg work, the existing surface must be stable, dry and bonded. If old waterproofing is lifting, blistering, cracked or trapping moisture, it should usually be stripped or corrected before new flat roof waterproofing work begins.

No. Torch-on is often suitable for larger exposed roof slabs and full membrane replacement, but flat concrete roof waterproofing can also require liquid coatings, reinforced details, board replacement or substrate repair. The correct system depends on the roof condition, drainage and failure points.

Send clear photos of the roof surface, leak area, drainage outlets, parapets, skylights, cracks, ponding water and any failed membrane areas. Also include the approximate roof size and suburb so TaylorMade Waterproofing can assess which solution is most appropriate.
