Why choose EPDM rubber roofing in Cowes?
Choose EPDM in Cowes 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.
In a town like Cowes, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or 1960s and 1970s link-detached houses with flat-roofed garages and porches. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does an EPDM rubber roof cost in Cowes?
For Cowes we use South East rates: £1,750–£3,100 is the guide for a typical 18 m² garage roof in EPDM, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,750–£3,100 |
| Extension (20 m²), EPDM, new deck + insulation | £3,100–£5,350 |
| Porch or bay (4 m²), EPDM | £850–£1,400 |
Do I need building regulations approval to replace a roof with EPDM?
Often, yes. In England, Wales and Northern Ireland, re-covering more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof should be insulated towards the renovation standard where that is feasible; in Scotland, the council's building standards service decides whether a building warrant is needed.
An unheated detached garage normally falls outside these rules, and a patch repair is treated differently from a full re-cover.
In practice that means a warm roof: insulation above the deck, a vapour control layer beneath it and the EPDM on top. The extra thickness lifts the finished roof, so at survey we check door thresholds, window cills, wall flashings and upstand heights, aiming for an upstand of about 150 mm above the finished surface. Where approval is needed, we deal with building control or building standards for you. The building regulations page and our warm vs cold roof guide go into more detail.
What's included?
- EPDM membrane fully bonded, in one sheet where the roof size allows
- Warm-roof insulation and vapour control layer where required
- Deck check and replacement of soft or rotten boards
- Strip-out of the old covering, with waste taken away
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.

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.
Can a punctured EPDM roof be repaired?
Usually, yes. The area is cleaned and primed, then an EPDM patch or cover tape is bonded over the damage. If water has reached the deck, a survey first is sensible.
