Roof Waterproofing
Roof waterproofing is not one product applied to every roof. A tiled roof, a sheeted roof and a concrete slab fail in completely different places and need completely different answers, and the most expensive mistake in this trade is treating them the same.

What roof waterproofing covers
A roof is waterproofed differently depending on what it is made of and how steep it is. Pick the one that matches your roof, or call and describe it and we will tell you which it is.
Our Process
The roof type decides the system, so nothing is specified before we have been on it. Preparation and substrate work are quoted as separate lines from the waterproofing.
- 1Free site inspection.
We get on the roof, identify the roof type, find the actual failure, and check what has been done to it before.
- 2Written quote.
The right system for the surface, with preparation and substrate work priced separately from the waterproofing itself.
- 3The work.
Preparation first, always. Then the specified system, with the details finished properly rather than approximately.
- 4Follow-up and guarantee.
Fred phones after the first proper rain. Written, minimum 2-year guarantee, with extended guarantees available on request, and a 10-year service guarantee where the work is maintained by us on an agreed cycle.

Why Choose TurboMax
We have been waterproofing in Cape Town since 2000. Fred owns the business, quotes every job himself and is on site. His son Thomas, who has worked alongside him since he was fifteen, runs the second team. Between them there is an owner on every roof, which a company running subcontractors cannot say.
The follow-up is what our reviews mention most. Fred phones after the first proper rain to confirm it held, before you have to phone him, and if it has not, we come back at our cost. He has always treated a comeback as more important than new work.
Written, minimum 2-year guarantee on the workmanship, with extended guarantees available on request, and a 10-year service guarantee where the work is maintained by us on an agreed cycle.
What Our Customers Say
Verbatim reviews from Google, alongside photographs of roof waterproofing we have actually done. No stock imagery.

Fred is a man of his word. The work they did on our roof was on time and good quality.

Repaired some leaks, redid the waterproofing and sprayed my entire roof with liquid rubber in 2 days at a reasonable price. They also guarantee their work for 2 years.

Run by a hands-on owner who impressed with his honesty and integrity. After the first rains, he contacted me to enquire about the work.

I received an extremely professional and friendly service. I was provided with expert advice throughout the project, which was completed well within time and under budget.

Excellent, professional, well-priced work. And a completely hassle-free process! 6/5. Thanks Fred!

Thank you TurboMax Waterproofing for your service and after service. I can definitely recommend your professional service.

Frequently Asked Questions
Straight answers, including the ones that talk us out of a bigger job.
What does roof waterproofing cost?
Roof type, the amount of detail on the roof, the condition of any existing system, and access are what move the number. A plain concrete slab and a slab of the same size with parapets, outlets and pipe penetrations are different jobs. We separate preparation from the waterproofing in the quote so you can see which is which.
Which waterproofing is best for a leaking tiled roof?
Usually none at first. A leaking tiled roof rarely needs a whole-roof treatment. It needs the failed detail repaired, a cracked tile replaced, a valley cleared, flashing refitted, then targeted sealing. A blanket coating over a tiled roof treats the symptom while the actual entry point carries on letting water in.
Do you use a waterproofing membrane on tiled roofs?
No. Membranes are engineered for flat, smooth surfaces and are seldom right on a pitched tiled roof. If a contractor has quoted you a full membrane layout for a tiled roof leak, that is worth a second opinion, and ours is free.
How often should a roof be checked?
Once a year, ideally in late summer or autumn before the winter rain arrives. Clearing gutters, checking for cracked tiles and removing plant growth is an inexpensive morning. Replacing a saturated ceiling is not.
Can you match the fix to my budget?
Yes, and we will be honest about what that costs you in the long run. We will tell you what has to be dealt with now to keep water out and what can safely wait a season, and we are happy to quote both. What we will not do is put a cheap coating over a structural failure and call it fixed.
