Get Waterproofing QuotesCommon Waterproofing Jobs in Johannesburg
- Roof leak repairs. Finding and fixing leaks that show up with the first summer storms.
- Flat roof waterproofing. Concrete flat roofs on houses, townhouses and offices, where blocked outlets cause ponding.
- Metal roof waterproofing. IBR and corrugated roofs on carports, extensions and warehouses with loose screws, rust and leaking laps.
- Tile roof waterproofing. Cracked tiles, loose ridge capping and leaking valleys, often after hail.
- Torch on waterproofing. New membranes and resealing of older torch-on that has cracked in the sun.
- Damp proofing. Rising damp and penetrating damp on walls of older houses.
- Shower waterproofing. Showers leaking into bedrooms, passages and ceilings below.
- Commercial waterproofing. Office roofs, podiums and parking decks, often for body corporates and managing agents.
What Johannesburg Weather Does to Roofs
- Summer thunderstorms. Short, heavy downpours overload gutters, outlets and downpipes and find every weak lap.
- Hail. Breaks tiles, dents and opens IBR laps, and can scour or puncture membranes.
- Sun and temperature swings. Strong UV and hot days with cool nights crack old torch-on, acrylic and sealants.
- Dry winters. The dry season is the easiest time to plan full re-waterproofing, because most systems need a dry surface to cure.

Get Waterproofing QuotesWhat Affects the Quote
- Season. Demand peaks once the summer storms start, so planned work booked in the dry months is easier to schedule.
- Size and system. Roof area and the membrane or coating chosen set most of the price.
- Preparation. Stripping old layers, crack repairs and screeding to falls add cost.
- Access. Double-storey roofs, steep pitches and scaffolding add to the quote.
- Hail damage. Replacing broken tiles or sheets is priced separately from waterproofing.
Hail Damage and Insurance
- Report quickly. Most insurers want hail damage reported soon after the storm.
- Get a written report. Ask the contractor for photos, a description of the damage and an itemised quote.
- Stop the leak first. A temporary repair can limit damage to ceilings while the claim is assessed.
Check your policy and speak to your insurer before work starts. Wear and tear on old waterproofing is usually not covered.
Complexes and Body Corporates
- Common property. In sectional title schemes the roof is usually common property, so trustees or the managing agent approve the work.
- Same scope. Ask each contractor to quote on the same roof areas, system and guarantee so quotes can be lined up.
- Phasing. Large complexes are often done block by block to spread the cost.
Questions to Ask a Johannesburg Contractor
- What do you think is causing the leak, and how did you find it?
- Which product system, how many coats or what membrane thickness?
- What preparation is included at outlets, upstands and cracks?
- What guarantee is offered, in writing, and what voids it?
- Can you start before the storms, and what happens if it rains mid-job?
Waterproofing Johannesburg FAQs
When is the best time to waterproof a roof in Johannesburg?
In the dry winter months. Most systems need a dry surface and dry weather to cure, and contractors are less busy before the summer storms.
Can a leak be fixed during the rainy season?
Yes. Contractors can usually make a temporary repair between storms and do the full job in a dry spell.
Does hail damage need waterproofing or roof repairs?
Often both. Broken tiles or dented sheets are replaced first, then damaged laps, flashings or membranes are resealed.
How much does waterproofing cost in Johannesburg?
Ballpark: torch-on R250 to R450 per m², acrylic systems R120 to R280 per m² and a small leak repair R1,500 to R5,000. Access, preparation and the system set the final price.
How many quotes should I get?
Two or three written quotes for the same scope and system are usually enough to see a fair price.
