Why choose EPDM rubber roofing in Cambridge?

For landlords with property in Cambridge, EPDM's low upkeep is the main draw: once the outlets are kept clear and the trims are checked once or twice a year, there is little else to do. It also goes down quickly on a small roof, which keeps disruption for tenants to a minimum.

In a large town like Cambridge, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or shops with flat-roofed rear stores below flats. 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.

When is EPDM the right choice, and when is another system better?

EPDM is a strong choice for simple domestic roofs that people do not walk on, such as garages, single-storey extensions, porches and dormers. It is less suited to roofs with regular foot traffic or many pipes and vents.

Where it does well: few or no joins on small roofs, flexible in cold weather, tolerant of minor building movement, and laid without a flame.

Where it falls short: the finish is plain dark rubber, it can be punctured by dropped tools or sharp debris, and it is not designed as a walking surface without added protection. Roofs with many penetrations take a lot of careful detailing.

If you want a hard, walkable finish or a complex shape, GRP fibreglass often suits better. On a tight budget, or a larger roof where a layered system is preferred, torch-on felt is worth pricing. Liquid-applied roofing handles awkward details and overlays, single-ply membranes are built for larger commercial roofs, and mastic asphalt belongs on older and heritage buildings. Our EPDM vs GRP vs felt guide sets them side by side.

What's included?

  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • Warm-roof insulation and vapour control layer where required
  • Strip-out of the old covering, with waste taken away
  • Written workmanship guarantee, plus manufacturer guarantee registration where available

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does an EPDM rubber roof cost in Cambridge?

£1,700–£2,950 for a typical 18 m² garage roof in EPDM, at East of England guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can you put a green roof on top of EPDM?

Yes. EPDM is often used under sedum, with a protection layer, drainage and growing medium laid on top. The structure must be able to carry the extra weight, which we check before quoting.

Does an EPDM roof need maintenance?

Very little. Clear leaves from outlets and gutters, look over trims and upstands once or twice a year and after storms, and keep foot traffic to a minimum.
