EPDM Flat Roofs In St Albans
Look behind the 1930s to 1970s homes in Marshalswick and Jersey Farm and you will find plenty of flat-roofed garages and extensions. Many still carry ageing felt. EPDM rubber gives them a clean, seamless covering, laid as a single sheet across the roof.
Options for your roof
We install and repair across all major options to suit your home and budget.

Garage roofs
A single seamless EPDM sheet stops garage leaks for good.

Extension roofs
Jointless rubber membrane ideal for rear extensions.

Dormer roofs
Neat EPDM on flat dormer tops with lead detailing.
EPDM roofs in St Albans
Most of our EPDM work in St Albans is on garages and single-storey extensions in Marshalswick, Jersey Farm, Sopwell and Cunningham, plus rear extensions on Victorian terraces in Fleetville and Bernards Heath. The old felt is usually split, blistered or holding water. We strip it, replace the deck and set the right fall, then bond the EPDM membrane in one piece. Edge trims finish it neatly, with an upstand and flashing where the roof meets the wall. Because the membrane has no seams across the roof, there are no joints to open up. It is a new roof, so it carries our 10-year guarantee.
Every job starts with a free survey and a written quote. Call 01727 649498 or book online.

On Fleetville terraces, rear extensions often sit side by side with a neighbour's, so we seal the junction cleanly and keep to your side of the boundary. Party wall rules can apply to some work. EPDM is best for roofs that are not walked on; if your extension roof is used as a terrace, we may suggest GRP.
