Flat Roof Replacement in Farnham
When a flat roof has reached the end of its life, a full replacement ends the cycle of leaks and patch repairs. Grange Roofing installs new flat roofs on extensions, garages and dormers across Farnham, using modern EPDM rubber, GRP fibreglass and high-performance torch-on felt systems.
New flat roofs come with a 10-year guarantee, and insurance-backed guarantees are available. We'll explain the options and give you a clear written price.
Signs your flat roof needs replacing
- ✓Leaks returning after several repairs

- ✓Roof over 15–20 years old

EPDM, GRP or felt?
EPDM rubber is a single-sheet membrane with no joints across most domestic roofs and a long lifespan. GRP fibreglass gives a hard-wearing seamless finish, ideal for roofs with foot traffic. Modern torch-on felt is a cost-effective, proven option. We'll recommend the best fit for your roof.
Insulation and falls
Replacing a flat roof in Farnham is a chance to add insulation and correct poor falls so water drains away instead of ponding. A warm roof build-up keeps rooms below more comfortable and helps meet building regulations.
A tidy, well-managed job
Most domestic flat roofs are replaced in one to three days. We protect your property, remove all waste and leave the site clean, with your guarantee explained before we leave.
