Local context — flat roofing in Harpenden
Flat-roof work in Harpenden (AL5) is dominated by single-storey rear extensions, garage roofs, dormer cheeks and porch roofs. St Albans District conservation team is among the strictest in the region — original clay tile, Code 5 lead and matching chimney pots are non-negotiable on any AL5 conservation-area reroof. For new flat roofs notifiable to St Albans City and District Council we provide the system spec, U-value calculation and fire-class evidence as standard — not an extra.
We work across AL5 with easy access from A1081 and M1 Junction 9.

Frequently asked — Flat Roofing in Harpenden
EPDM rubber or felt — which is better?+
For most extensions in Harpenden 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 Harpenden 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 AL5?+
Emergency patch repairs in AL5 are usually a same-week visit. We tarpaulin if needed, then quote properly for a long-term fix.
