What flat roof work do we do in St Albans?

EPDM rubber roofing

Choose EPDM in St Albans if you want a long service life without paying for a hard, walkable finish you do not need. With good detailing it typically lasts 25 years or more, and manufacturer material guarantees are available on many EPDM systems, registered for you where the system allows.

Single-ply membrane roofing

On exposed sites in St Albans and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.

What flat roofs are typical in and around St Albans?

In a large town like St Albans flat roofs are mostly on low-rise post-war blocks of flats and newer estates where the first extension roofs are now being replaced. Rain and wind decide how a flat roof is detailed. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to St Albans City and District Council building control, or a registered building control approver.
