Waterproofing in Pretoria and Centurion

Pretoria sits on the Highveld, where rain arrives as intense summer thunderstorms between roughly October and March, often with hail, and then stops almost entirely for the dry winter. A roof can look fine for months and then leak heavily in a single storm when a blocked outlet or a hairline crack is overwhelmed by a sudden downpour.

The same climate is hard on waterproofing: strong year-round UV bakes exposed membranes and coatings, and the big day-to-night temperature swing makes roofs expand and contract, working at laps, parapets and flashings. Systems used here have to tolerate that movement and UV, which is why we assess the specific roof before recommending one.

On flat concrete roofs we most often find ponding at blocked outlets, cracked parapet copings and aged or over-painted waterproofing that has started to blister. On pitched tiled roofs the usual culprits are cracked tiles, failed ridge and valley flashings and perished underlay.

At ground level, soil and garden beds built up against walls bridge the damp-proof course and cause rising damp, and retaining walls on sloped Pretoria East stands push water through to the house side when they were never waterproofed or drained on the soil side.

Roof waterproofing and leak repair on flat concrete, tiled and metal roofs; parapet, flashing and outlet detailing; damp-proofing and rising-damp treatment; and retaining and foundation wall waterproofing. We recommend a torch-on, liquid or coating system to suit each roof rather than applying one product everywhere.

Every job starts with photos or an on-site assessment (we confirm the call-out fee first) and a written quote. We do not publish a rate per square metre because a Garsfontein flat roof, a Centurion townhouse parapet and a Moreleta Park retaining wall are genuinely different jobs.

Send photos of the stain, roof or damp wall by WhatsApp or the quote form and tell us the suburb. We arrange an assessment, find where the water is getting in, and give you a written quote that names the system and the warranty terms before any work starts.
