Local context — flat roofing in Northwood
Flat-roof work in Northwood (HA6) is dominated by single-storey rear extensions, garage roofs, dormer cheeks and porch roofs. Hillingdon's Article 4 direction across Northwood restricts external alterations without planning — even like-for-like tile changes on front elevations need householder consent for larger detached properties, which we lodge before quoting. For new flat roofs notifiable to London Borough of Hillingdon we provide the system spec, U-value calculation and fire-class evidence as standard — not an extra.
We work across HA6 with easy access from A404 and Rickmansworth Road.

Frequently asked — Flat Roofing in Northwood
EPDM rubber or felt — which is better?+
For most extensions in Northwood 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 Northwood 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.
Can you insulate during a flat-roof renewal?+
Yes — a warm-roof build-up with 100mm+ PIR insulation transforms an old extension's energy performance and is now standard under Part L for notifiable jobs.
How quickly can you fix a leaking flat roof in HA6?+
Emergency patch repairs in HA6 are usually a same-week visit. We tarpaulin if needed, then quote properly for a long-term fix.
