How much does flat roof repair cost?
The price covers the leak tracing, the materials that match your covering and the labour to seal the defect. What changes it is how far the damage has spread, which membrane is fitted and the state of the boards below.
Looked at and put right
- Detailed visual examination of the membrane, drip trims and perimeter flashings
- Cleaning and clearing moss, silt and loose chippings from the repair zone
- Patching tears, splits and punctures using material-matched bonding agents
- Resealing loose laps, joints and detailing around roof penetrations
- Checking rainwater outlets and gutter discharge points for clear drainage
- A single split or open joint costs less to put right than wear spread across the whole roof.
- Felt, GRP and EPDM each need different preparation and adhesives, which moves the price.
- Rotten decking cannot take a patch, so damaged boards are talked through and priced as their own job.
- Clearing blocked outlets is part of the visit rather than an extra.

What happens on the day
Water can enter at one point and travel along the joists before it marks a ceiling, so every visit starts by locating the true entry point before any patching.
- Surface and edge inspectionWe go over the covering for ponded water, open laps, punctures and worn seals where the roof meets walls, parapets and rooflights.
- Deck and ceiling checkThe boards under the membrane get pressed for softness and bounce, and the ceiling below shows how far the water has spread.
- The repair explained firstYou hear what we found and whether a localised patch will keep the water out or wider work is worth considering, before anything starts.
- Patching and drainageSplits, seams and punctures are sealed with materials matched to the covering, and outlets and discharge points are cleared so rain can leave the roof.

Flat roof repair questions
How do you find where a flat roof is leaking?
Water almost never drips straight through. It gets in at a seam or split, runs along the joists and can mark a ceiling metres from the defect, so we trace open joints, cracked flashing and ponded areas above the stain.
Can flat roof repairs be done in wet weather?
Bonding to felt, GRP or EPDM needs a dry surface, so rain can push the work to the next dry spell. Temporary protection can limit the water getting in until conditions allow a lasting seal.
What causes a flat roof to start leaking?
Felt splits along its joints, fibreglass crazes where it cannot flex and rubber lifts at glued seams and upstands. Blocked outlets and water sitting on the surface speed all three up.
Which flat roof coverings do you repair?
We repair mineral felt, GRP fibreglass and EPDM rubber. Each material takes a different fix, so identifying the covering is the first step of the inspection.
Will a patch stop the leak for good?
A correctly bonded patch seals that defect for the life of the covering around it. We also tell you how the rest of the roof is doing, so an ageing membrane does not catch you out later.
