Flat Roofers in Balham
Fast Call Roofing installs new flat roofs and repairs existing ones throughout Balham. We work with GRP fibreglass (glass reinforced polyester) and traditional leadwork, on homes and commercial buildings alike.
Balham is mainly Victorian and Edwardian terraced and semi-detached housing, with many houses extended into the loft and at the back. That means a lot of dormer, valley and flat roof work alongside the main slate or tile roof.
In Balham, flat roofs usually cover rear extensions, bathrooms, bay windows and loft dormers. Older felt or asphalt roofs here often crack, blister and pond, and replacing them with GRP fibreglass gives a seamless, durable finish.
We also offer roof repairs in Balham and a full roofing service in Balham.
A durable, long-lasting flat roof for your Balham property
Fibreglass roofing systems offer a durable and long-lasting solution for both flat and pitched roofs in Balham. Unlike traditional felt roofing, fibreglass is significantly stronger and more resistant to deterioration. Its seam-free construction minimises the risk of leaks and water ingress, while its ease of repair ensures fast and efficient maintenance.
For domestic properties, fibreglass roofing provides numerous benefits. Its outstanding durability and longevity mean a roof that can withstand the test of time, reducing the need for frequent repairs. The seamless design and repairability further enhance its reliability, to ensure a worry-free roofing experience.

Flat roofing FAQs for Balham
Common questions about flat roofs and GRP fibreglass in Balham.
Do you install flat roofs in Balham?

What is a GRP fibreglass flat roof?
GRP stands for glass reinforced polyester. It’s a liquid-applied fibreglass system that cures into a single seamless, ultra-hard layer with no joints. It is fire retardant, impact resistant and completely waterproof, and it’s applied cold, so no heat is needed.
How long does a ProGRP flat roof last?
The ProGRP system we install comes with a 25-year guarantee and has a life expectancy of 25 years. It doesn’t crack, split or deteriorate like traditional felt, and it needs very little maintenance.
Can you replace the flat roof on my rear extension in Balham?
Yes. Rear extension flat roofs are one of our most common jobs. We strip the old roof, check the deck and fit a new seamless GRP fibreglass roof with properly detailed edges and upstands.
Can you repair my existing flat roof instead of replacing it?
Often, yes. We’ll inspect the roof, check the deck and drainage and tell you honestly whether a repair will last or whether replacing it with GRP fibreglass is better value.
