Islington — N1

Flat Roof Repairs in Islington N1

Flat roofs are everywhere in N1: the back additions of Georgian and Victorian terraces, the flat-topped dormers of loft conversions, and the small roofs over bay windows and outriggers. When one starts to leak, the water often reaches a kitchen or bedroom ceiling before anyone sees the roof. KC Roofing & Scaffolding repairs flat roofs across Islington, including the streets around Upper Street, Barnsbury and Canonbury.

Most flat roof leaks in Islington start at the edges rather than the middle of the roof. Perimeter upstands, the junctions with the main house wall, and the lead or trim at the parapet are where movement and weather do the most damage. A patch in the middle may look like a fix, but it often just moves the leak. We check the edges first.

Many N1 flat roofs were covered decades ago, and some have been overlaid more than once. Each extra layer adds weight and can trap moisture underneath. Before any repair, we check what is there and whether it can take a repair or needs replacing, and we give you a written quote with the options.

Loft conversions add their own pressure points. Dormer cheeks, the junction with the pitched roof above, and rooflight kerbs are common sources of leaks in converted N1 houses. We look at these during the same visit, so a repair to the flat roof does not leave a weak point beside it.

What we repair on Islington flat roofs

Edge and upstand repairs

Perimeter upstands and wall junctions are re-sealed or re-flashed so water runs off rather than tracking behind the trim.

Felt and liquid roof repairs

Torn or blistered felt is cut out and re-laid in sound material. Liquid-applied surfaces are cleaned, primed and re-coated where the coating has failed.

GRP fibreglass repairs

Cracked or lifting GRP is cut back, prepared and re-laminated. Where the laminate has worn through to the base, we repair the base before the new surface goes on.

Conversions, parapets and period buildings

Dormers and loft conversions

We check the join between the flat dormer roof and the pitched roof above it, along with the cheeks and rooflight kerbs, which are frequent sources of leaks in converted houses.

Parapets and coping

Where a flat roof sits behind a parapet wall, loose coping stones and failed lead at the wall junction are often the real cause of a leak. We repoint loose coping and renew lead that has failed.

Listed and conservation buildings

Some Islington houses are listed or sit within conservation areas. In those cases the council may have rules on materials and details, so we confirm these with you before any work is planned.

Flat Roof Repairs in Islington — FAQs

Why is my flat roof leaking at the edge but not in the middle?

Water usually enters where the roof meets a wall, parapet or upstand. Movement and worn trim at these junctions let water in even when the main covering is sound, so checking the edges first is usually the quickest way to find the leak.

Will a flat roof repair last, or will it need redoing?

A well-prepared repair to a sound base can last for years. If the existing covering is worn through or has several layers, we'll say so and set out the replacement option alongside the repair.

Do you repair flat roofs on loft conversions?

Yes. Flat dormers and their junctions with the main roof are part of our flat roof repair work. We check cheeks, rooflights and the join with the pitched roof during the same visit.

Will I need scaffolding for a flat roof repair?

Many flat roof repairs are done from a ladder or a safe working platform. Where we need access equipment for our own roofing work, we provide it in-house. We do not offer scaffold hire on its own.
