Flat Roof Repairs fix damaged parts of a flat roof, such as torn or blistered membrane, blocked outlets, cracked screed, ponding and failed parapet details. Flat roofs leak fast once a weak spot opens, so it pays to repair early. Send one request and local contractors will contact you with prices.

- Ponding water. Water stands for days after rain, which strains the surface.
- Blisters or bubbles. Trapped moisture lifts the membrane or coating.
- Splits and tears. Often at joints, edges or around pipes.
- Cracked parapets or copings. Water gets in at the top or side of the wall.
- Ceiling stains below. A sign water is already through.
What the Work Includes
- Patch repairs. Damaged membrane cut out and patched, with laps sealed.
- Outlet and drain fixes. Blocked or loose outlets cleared, reset and sealed.
- Screed corrections. Low spots built up so water runs to the outlets.
- Upstands and parapets. Cracked copings and wall junctions repaired and sealed.
Repair or Re-waterproof?
- Repair when damage is in a few spots and the rest of the surface is sound.
- Recoat when the surface is tired but not failing, to add another layer of protection.
- Re-waterproof when leaks keep coming back in new places. See flat roof waterproofing for full systems.

- Size of the damaged area. A small patch costs far less than a large failing section.
- Ponding. Fixing falls with screed adds to the cost but stops repeat damage.
- Existing system. Torch-on, coatings and liquid membranes are each repaired differently.
- Access. Multi-storey buildings may need scaffolding.

Flat Roof Repairs FAQs
Why does my flat roof keep leaking?
Ponding, blocked outlets and failed joints are the usual causes. Patching without fixing the fall often leads to repeat leaks.
Can a flat roof be repaired in the rainy season?
Small emergency patches can be done, but most materials need a dry surface to bond properly. Larger work is usually planned for dry weather.
What causes blisters on a flat roof?
Moisture or air trapped under the membrane expands in the heat. Blisters are cut, dried and patched.
When is a full re-waterproof better than repairs?
When leaks appear in several places or the membrane is brittle across the whole roof, a full system is better value than repeated patches.
