Local context — flat roofing in Old Windsor
Flat-roof work in Old Windsor (SL4) is dominated by single-storey rear extensions, garage roofs, dormer cheeks and porch roofs. Old Windsor sits inside the Windsor Great Park setting area — Royal Borough conservation officer coordinates with the Crown Estate on any visible-elevation work close to park boundary. For new flat roofs notifiable to Royal Borough of Windsor and Maidenhead we provide the system spec, U-value calculation and fire-class evidence as standard — not an extra.
We work across SL4 with easy access from A308 and Straight Road.

Frequently asked — Flat Roofing in Old Windsor
EPDM rubber or felt — which is better?+
For most extensions in Old Windsor we recommend single-ply EPDM rubber: one-piece installation, 25+ year life and no seams to fail. Torch-on felt is still the right call for some applications and budgets.
How long does a flat roof last?+
A properly installed EPDM rubber flat roof in Old Windsor should give 25-30 years; high-performance torch-on felt 15-20 years.
Can you overlay my existing flat roof?+
Sometimes — only if the deck and existing covering are sound. We'll always inspect and recommend a strip-and-refresh where overlay would just store up problems.
Do you fit GRP fibreglass flat roofs in Old Windsor?+
We focus on EPDM and high-performance felt because they outperform GRP on residential extensions in our experience — fewer cracking issues, easier repair, longer life.
How do you stop ponding on a flat roof?+
Proper fall (1:80 minimum) built into the deck during install. We won't lay EPDM over a deck without adequate fall — it's the single biggest cause of premature flat-roof failure in Old Windsor.
