Flat Roofing
Durable, genuinely watertight flat roofs for extensions, garages and dormers — built to outlast old felt.
Flat roofs that actually last
Old felt flat roofs crack, blister and leak. We fit modern systems like EPDM rubber and GRP fibreglass that stay watertight for decades, with proper falls so water drains away instead of pooling.
What's included
- EPDM rubber and GRP fibreglass systems
- Correct falls to prevent ponding water
- New trims, drips and outlets
- Insulation upgrades for warm-roof builds

Questions, answered
What's the difference between felt and GRP flat roofing?+
Felt is the traditional built-up system; GRP (fibreglass) is a single seamless membrane that typically lasts longer and needs less maintenance.
How long does a flat roof system last?+
A well-installed modern flat roof system typically lasts 20-25 years before a full replacement is needed.
Can a flat roof be walked on?+
Only if it's specifically designed and reinforced for foot traffic — standard flat roofs shouldn't be walked on regularly.
Can you fit a flat roof on my extension?+
Yes — extensions, garages, dormers and porches are all jobs we handle regularly.
Will it leak like my old one?+
Modern systems are seamless and far more reliable. With correct falls and detailing, leaks become a thing of the past.
