Flat Roof Repair in West Ealing, London

How an urgent kitchen roof leak in West Ealing was fixed with flashing repairs, a new torch-on felt roof system and two new guttering systems.

Client

Location

West Ealing, London

Roof type

Flat kitchen roof

System installed

Torch-on felt

The problem

Jean Philippe's kitchen roof in West Ealing had started letting in water and needed urgent attention. The flashing around the perimeter was part of the problem, and the guttering needed replacing too, so the fix had to deal with how water was getting in as well as how it drained away.

The goal

Stop the leaks quickly and leave the kitchen roof — and its drainage — fully watertight.

How we did it

1

Cleaning and drying

The roof was cleaned and dried out ready for the new system.

2

Bitumen primer

A bitumen primer was applied to give the new felt a strong bond.

3

Perimeter flashing repairs

The flashing around the perimeter of the roof was repaired.

4

New torch-on felt roof system

A torch-on felt roof system was installed across the kitchen roof.

5

Two new guttering systems

Two new guttering systems were installed so rainwater drains away properly.

The results

Roof system

Torch-on felt

Guttering

2 new systems

"I recommend Knights Roofing. Kitchen roof needed urgent work after some water leaks and they have been very reactive. Quality 100% there. Quotation was clear, very easy to interact with Kristal and Luke at each stage of the process. Thanks a lot"
