Flat roof repairs and felt roofs
Flat roofing in Kent.
Most flat roof leaks start at the edges, where felt turns up a wall, meets a window or finishes at a trim. Across Dartford, Gravesend, Sevenoaks, Maidstone and the surrounding towns, we repair those details where the deck is sound. When the roof has gone too far, we lay a new torch-on felt system.

Where flat roofs leak first
The main sheet of felt is often in better shape than its edges. Upstands crack where they meet brickwork, joints open up and trims lift, letting water run in behind the covering. Flashings above an upstand can also come loose, which makes a sound roof appear to have failed.
- Cracked felt along an upstand
- Lifting edges around the trims
- Open joints between felt layers
- Loose lead or flashing at the wall
Flat roof repairs that make sense
Where the deck is sound, we repair splits and blisters and reseal joints and upstands to get more life from the roof. A repair won’t help if water has been getting in for a long time and the boards have softened. In that case we’d show you the evidence and price a new covering instead.

New felt roofs on Kent homes
Loft dormers, rear extensions and garages are the most common flat roofs on houses around Bexleyheath, Sidcup and Orpington, while bay windows appear on older homes in towns like Tonbridge and Rochester. Dormers need care at the cheeks and windows, because there’s little room for error. A new roof comes with fresh decking where needed, and new trims, drips and upstands.

- Rear and side extensions

Common questions
Can a dormer flat roof be repaired from outside?
Usually, yes. Most repairs are carried out on the roof surface and at the edges, though we’ll need safe access to the dormer. We’ll explain what is needed when we quote.
What causes blisters in flat roof felt?
Blisters tend to form when moisture or air is trapped under the felt and expands in the sun. A small, unbroken blister may not need work yet, but a split one should be repaired.
How can I tell if my flat roof deck has rotted?
Sagging ceilings below, soft spots on the roof and repeated leaks are all warning signs. We’ll check the deck carefully and show you what we find.
