The sooner a flat roof leak is found, the more of the deck you save.
Drips along the back wall
Water appearing where the extension ceiling meets the house wall points to a failed upstand or flashing on the roof above it.
A puddle that never dries
Ponding in one spot means the deck has sagged there. The covering under the water ages faster than the rest and splits first.
Water running behind the gutter
If water runs down the wall behind the gutter, the felt or trim at the roof edge is not dripping into it. The fascia and deck edge rot next.
A split seam or lifted lap
On felt and older membranes, the overlaps between sheets lift with age. Rain gets in and tracks along under the covering before it shows inside.
Leaks around a rooflight
Rooflights on flat roofs sit on kerbs that need their own upstand detail. When that fails, water shows on the kerb or the ceiling around it.
How Patrick finds a flat roof leak
Flat roof leaks travel. Water gets in at one point, runs along the deck under the covering and drips out somewhere else. Patrick checks the ceiling below, then goes over the roof, the upstands, the outlets and the trims, and finds where it is really getting in. He photographs it and shows you. One customer summed it up on Google: "made it very easy along the way showing me photos and excepting payment on completion".
The repair matches the roof. On felt, split areas are cut out and patched with new torch-on layers, and failed upstands are re-dressed under a new flashing. On EPDM, a cut or lifted seam is cleaned, primed and covered with a compatible rubber patch. On GRP, cracks are ground back and relaminated with new mat, resin and topcoat. Wet sections of deck are cut out and replaced. You pay when the roof is watertight.

Flat roof leaks around Croydon
Flat roof leaks in Croydon come from the same few places again and again: the joint where a rear extension meets the house, the outlet where the roof drains into a hopper, and the edges of box dormers where felt meets tile hanging. The older extensions behind Victorian terraces in Selhurst and Thornton Heath and the 1970s additions on semis in Shirley and Addington often still have their first felt roof. Summer downpours and long wet winters both find those weak spots.

The fault sets the price of the repair
Flat roof repairs are priced on the fault and how much of the roof it has damaged. A split seam caught early is a small repair. A leak that has soaked the deck for months means cutting out and replacing boards before the covering goes back. The material matters too, because felt, EPDM and GRP each repair differently. Patrick finds the cause, shows you the photos and agrees the price before any work begins.
What sets the price
- Where the leak gets in
- How much deck is wet
- Felt, EPDM or GRP
- Upstands and flashings
- Outlets and rooflights
- Access to the roof
Flat roof repairs questions
How do you find a leak on a flat roof?
Start from the stain inside, then check the roof above and uphill of it, because water runs along the deck before it drips. Upstands, outlets, seams and rooflight kerbs are the first places to look. Patrick checks all of them, feels for soft deck underfoot and photographs the exact point where water gets in, so you see it too.
Can a flat roof be repaired rather than replaced?
Yes, if the leak is local and the rest of the covering and deck are sound. A single split, a lifted seam or a failed flashing is a repair. If the felt is cracked all over, blistered across the roof or the deck is soft in several places, a new roof costs less over time. Patrick tells you which, with photos to back it up.
What causes a flat roof to leak in a downpour?
A flat roof that leaks in a downpour but stays dry in drizzle has a fault near an upstand, outlet or edge that only floods when water builds up. Light rain drains away before it reaches the gap. In a downpour, water backs up at a blocked outlet or rises behind a lifted flashing and gets in. Clearing the outlet sometimes cures it, and if not, the detail needs redoing.
Is patching a flat roof worth it?
Yes, if it is a proper repair and not a smear of sealant. A repair in the same material as the roof, bonded to sound covering, lasts as long as the roof around it. Sealant brushed over a split gives you one season. Apex repair felt with felt, rubber with rubber and GRP with GRP, so the new material bonds into the old and becomes part of the roof.
Is a flat roof repair guaranteed?
Yes, flat roofs are fully guaranteed, so your repair is covered in writing before the team leaves. Patrick tells you the terms for your repair before you agree, so you know exactly what is covered. A repair only works if the cause is fixed, which is why he traces the leak before anything else.
