Why choose EPDM rubber roofing in Croydon?

If your Croydon roof has been patched more than once and the felt is cracking or blistering, a full replacement in EPDM can be better value than another repair. The rubber stays flexible through hot summers and freezing nights, and the replacement is the right point to bring the insulation up to standard.

In a town like Croydon, flat roofs are commonly found on kitchen extensions and roof terraces behind period houses or Victorian and Edwardian terraces with flat-roofed back additions. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

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?

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

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.

Who checks building regulations for a flat roof in Croydon?

Where the work needs approval it goes to London Borough of Croydon building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does an EPDM rubber roof cost in Croydon?

£1,900–£3,350 for a typical 18 m² garage roof in EPDM, at London guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

Can EPDM be laid over an old felt roof?

Sometimes, but we usually recommend stripping old felt first. Overlaying hides any rot or wet insulation underneath, and over a heated room a full replacement is often when insulation has to be added anyway.
