This website connects you with contractors. It does not do the work itself, and it promises no leak-free roof.
What this website does
Johannesburg roofs take a hard summer. Highveld storms arrive from October, bring hail and wind, and find every cracked tile, lifted flashing and blocked valley on the way. By the time water shows on a ceiling, the roof has usually been working on the problem for a while.
Roof Waterproofing Johannesburg is a website that connects homeowners, landlords and bodies corporate across the Johannesburg metro with independent waterproofing contractors. You tell us your suburb, what the roof is doing and what you need. We pass the enquiry to a contractor who covers your area. The contractor contacts you, looks at the roof where needed and quotes you directly. You decide whether to go ahead.
We do not waterproof, repair or inspect roofs ourselves, and we do not set the price. The contractor does the work and is responsible for it, including the system and the warranty they offer.
Two ways in: the roof, or the leak
People usually arrive here for one of two reasons. Either they want a leak stopped now, or they want a roof protected before the next season. We keep those apart, because they are different jobs with different answers.

Roof waterproofing
A waterproofing system is not a tin of paint. It is a chosen layer over a prepared surface, and it lasts as long as the surface under it. We connect you with an independent Johannesburg waterproofing contractor who assesses the roof and quotes you directly.Leaking roof repair
When water is coming in, the first job is to find where it enters, not where it lands. A leak repair is a search before it is a repair. We connect you with an independent contractor who covers your suburb and can trace and fix the leak.Roof repairs
Not every roof problem needs a new layer over the top. Sometimes the honest fix is a repair: a tile replaced, a flashing renewed, a ridge re-pointed, a gutter cleared. We connect you with an independent contractor who repairs Johannesburg roofs.Flat roof waterproofing
A flat roof is not really flat. It needs a fall to move water to an outlet, and it needs a membrane that can take standing water, heat and traffic. We connect you with an independent contractor who waterproofs Johannesburg flat roofs.Damp-proofing
A damp patch on a wall is a symptom, and it has several possible causes: rising damp from the ground, water getting in from outside, a roof or gutter leak, or plain condensation. They need different trades, so the cause comes first.Body corporate and complex waterproofing
A complex roof is a shared asset, and the decision to waterproof it runs through the trustees, the levy and sometimes a special resolution. We connect bodies corporate, managing agents and homeowners with an independent contractor who works on shared roofs.Done properly, or done twice
A waterproofing system is only as good as the surface under it. A coating or a membrane bonded to a clean, dry, sound roof lasts as long as that roof does. The same system over a surface that is cracked, damp or still moving will lift and fail early, whatever the product is.
That is why preparation is the real subject of a waterproofing quote: cleaning, repairing cracks and loose material, renewing the flashings, and treating the joints where the roof meets a wall, a parapet or a pipe. When you compare quotes, compare the preparation first. Our guide to what moves a waterproofing quote explains what to look for.
No contractor can promise a roof will never leak, because that depends on the system chosen and the state of the roof underneath. What a good contractor can do is match the system to your roof and stand behind their work.
Johannesburg areas we cover
Roofs change across the metro. In Sandton, Fourways and Bryanston, large homes and dense complexes mix pitched tile with flat concrete, and many flat sections are due for renewal. Randburg and Roodepoort carry a lot of 1960s to 1980s housing on its second or third coating. Alberton and Kempton Park sit under the eastern hail belt, and Midrand and Benoni run from new estates to older plots under heavy tree cover. Our area pages explain what to expect where you live.
How it works
Tell us about the roof. Your suburb, what you can see and how to reach you.
We pass on the enquiry. We send it to an independent contractor who covers your area and does that kind of work.
The contractor contacts you. They ask questions, look at the roof where needed and quote you directly.
You decide. There is no obligation to accept a quote. Your agreement for the work is with the contractor.
Before any work starts, ask the contractor what system they propose, what preparation is included and what their warranty covers. Keep the quote and the warranty with your house papers.
Before the summer storms
Gauteng's rainy season starts in October, and the dry months before it are the best time to look at a roof, because waterproofing needs a dry surface to bond. Clear the gutters and valleys, check the ridges and flashings, and note any stain on a ceiling. If the coating has worn through across the roof, renew it before the rain rather than patching through the season. Our guide to preparing a roof before the summer storms sets out the checklist.

Frequently asked questions
Does this website do the waterproofing?
No. It connects you with independent waterproofing contractors who cover your area. The contractor assesses the roof, quotes you directly, does the work and is responsible for it.
Will waterproofing stop my roof leaking for good?
No one can promise a roof will never leak again. That depends on the system chosen and the state of the roof underneath. A contractor can choose the right system for your roof and stand behind their work.
Which parts of Johannesburg do you cover?
Enquiries are taken from across the Johannesburg metro, with local pages for Sandton and the northern suburbs, Randburg and Roodepoort, the south and south-east, and the East Rand and Midrand.
Do you publish prices?
No. Contractors set their own prices after seeing the roof. We explain what moves a quote so that you can compare quotes fairly.
Where do I start if I am not sure what my roof needs?
Describe what you can see: a stain on the ceiling, damp on a wall, cracked tiles or water standing on a flat roof. Choose the closest service on the form, or pick something else, and the contractor will take it from there.
