What happens on the day
Every inspection evaluates the outer waterproof skin and the structural timber deck below so that you receive an accurate diagnosis before work commences.
- External membrane and drainage inspectionWe access the flat roof to check for ponding water, fractured seams, loose lead flashings, cracked drip trims and degraded upstands against adjoining house walls or skylight curbs.
- Timber decking firmness checkWe test the decking boards beneath the covering for softness, spring or rot caused by hidden water penetration, confirming whether the timber structure remains sturdy enough to support a lasting patch.
- Internal leak point matchingWater often travels horizontally across joists before dripping through a plasterboard ceiling. We compare internal damp stains with external defects to ensure the true entry path is addressed directly.
- Clear explanation of repair choicesWe explain our findings plainly, setting out whether an isolated patch will cure the leak or if wider degradation across the roof deck makes covering replacement the practical approach.

Common questions about flat roof repairs
Can a leaking flat roof be patched instead of fully replaced?
Yes, a flat roof can be patched if the underlying timber deck boards remain solid and dry, and the defect is isolated to a split seam, tear or cracked flashing. If the covering has degraded everywhere or the decking feels spongy underfoot, patching will only delay an inevitable replacement.
Why does water collect in pools on my flat roof?
Ponding happens when a flat roof has an insufficient fall or when deck boards have sagged between joists over time. While modern membranes tolerate shallow standing water, chronic ponding accelerates wear at lap joints and collects silt that blocks drainage outlets.
Can you repair a flat roof during wet weather?
Temporary sealing can be carried out to prevent internal water ingress while it is raining. Permanent repairs using torch-on felt, fibreglass resins or rubber adhesives require dry deck surfaces to cure and bond reliably, so permanent repairs are scheduled in dry conditions.
Why do detached garage roofs in Whitley and Southcote leak at the edges?
Postwar garage blocks frequently leak along the perimeter drip edges where the felt folds over a timber batten into the gutter. This outer edge suffers the greatest movement from seasonal expansion, causing older felt to crack open long before the main body of the roof fails.
How do you find the source of an internal ceiling leak?
Water often enters through a cracked flashing, split seam or rooflight curb several feet away from where the damp patch appears inside. Rainwater runs along timber joists or foil insulation before finding an exit. We trace the slope and examine common failure points to find the true entry.
