Flat Roof Waterproofing
Flat roof waterproofing fails for one reason more than any other: the water has nowhere to go. Before we specify a membrane we check where your roof drains, because a perfect membrane laid on a slab that ponds is a membrane on a countdown.

Our Process
We watch where the water goes before specifying anything. If the falls are wrong, correcting them happens first and is quoted as its own line.
- 1Free site inspection.
We get on the slab, check the falls, the outlets, the parapets and the condition of what is already there.
- 2Written quote, honest on repair versus redo.
Localised repair where the membrane is otherwise sound, full replacement where it is not, with preparation and screed correction priced separately.
- 3The work.
Torch-on membrane across the field of the slab, liquid rubber at outlets, upstands, cracks and parapet junctions.
- 4Follow-up and guarantee.
Fred phones after the first proper rain. Written, minimum 2-year guarantee on the workmanship.
Why Choose TurboMax
Flat roofs are the work we have built the business on. Torch-on is our specialty, Fred quotes and runs every project himself, and his son Thomas manages the second team, so there is an owner on your roof rather than a crew sent out with a spec.
The follow-up is what our clients mention most. Fred phones after the first heavy rain to confirm the ceiling is dry, before you have to phone him. If something has not held, we come back at our cost. He has always treated a comeback as more important than new work, which is why most of what we do still arrives by word of mouth.
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.

Verbatim reviews from Google, alongside photographs of flat 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 drives the price of a flat roof waterproofing job?
Condition far more than size. Stripping a failed system and disposing of it, correcting falls so water actually reaches the outlets, and detailing around outlets and parapets are the expensive parts. The open slab is the cheap part. A roof with four outlets, three pipe penetrations and forty metres of parapet is far more work per square metre than a plain slab of the same area.
Does my roof need a repair or a full redo?
Localised damage on an otherwise sound membrane is a repair, and we will say so, because patching is cheaper for you and it works. Widespread blistering, cracking and lifting means replacement, and patching that is money thrown away. The inspection settles it before you commit to anything.
My roof pools water after rain. Does that matter?
It matters more than almost anything else on the roof. Standing water tests the membrane continuously and finds weaknesses moving water never would. Tell us upfront if your roof ponds, because it changes the approach: the falls or the outlets have to be corrected as part of the work rather than covered over.
My flat roof has been coated three times already. Can you just add another layer?
We would rather not, and here is why. Each layer applied over a failed system traps moisture underneath and adds to what eventually has to be stripped. We will inspect and tell you honestly whether there is anything sound left to build on. Sometimes there is. Often the honest answer is that it all comes off first.
The damp is along the ceiling near an outside wall, not in the middle of the room. Is that still the roof?
Very often, yes, and it usually points at the parapet rather than the slab. That pattern gets misdiagnosed as wall damp and treated from inside the room repeatedly. Checking the coping and the slab-to-parapet junction is part of every flat roof inspection we do.
