Weald weather is hard on flat roofs — long spells of rain and heavy tree cover mean standing water and blocked outlets are common. Cheap felt systems fail here in five to seven years. Modern EPDM rubber and GRP fibreglass, installed properly, will last 20 to 30.
We install and replace flat roofs on extensions, dormers, garages, porches and small commercial premises throughout Horsham, Broadbridge Heath, Southwater, Billingshurst, Storrington and out into the surrounding villages.

What's included
- Strip of existing failed flat roof
- Timber deck inspection and replacement
- PIR insulation upgrade where appropriate
- Firestone / Classicbond EPDM installation
- GRP fibreglass roofing with UV-stable topcoat
- New trims, kerbs and abutment flashings
- New outlets, gutters and rainwater goods
Common problems we fix
- Blistering three-layer felt with ponding water
