EPDM rubber roofing in Worthing

Garage leaking, or an extension roof that has blistered and split? For property owners in Worthing, EPDM rubber is a practical replacement. It is laid cold, copes with temperature swings and leaves few or no joins on a small roof. A free survey tells you whether the deck can be kept or needs replacing.

Why choose EPDM rubber roofing in Worthing?

For landlords with property in Worthing, 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.

Worthing's flat roofs are mostly on bungalows with flat-roofed side extensions and dormers, with plenty on low-rise post-war blocks of flats too. 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 are the joins, edges and upstands made watertight on an EPDM roof?

They are bonded with contact adhesive and sealed with purpose-made EPDM tapes and pre-formed pieces, because the edges and details are where most rubber roof leaks start.

  • Wall upstands: the rubber is turned up the wall, usually to about 150 mm above the finished roof, fully bonded, then finished with a termination bar or a cover flashing chased into the masonry.
  • Corners: folded rather than cut where possible, or finished with pre-formed pieces.
  • Joins: on roofs wider than one sheet, the laps are cleaned, primed and joined with splice tape, then rolled firmly.
  • Pipes and vents: sealed with pre-formed pipe boots rather than relying on mastic.
  • Edges and outlets: drip and kerb trims are fixed and the junction with the membrane is sealed with cover tape; outlets are bonded into the membrane at the lowest point.

We also check the falls before laying, because standing water around an outlet shortens the life of any detail. There is more on this in our pages on edges and drainage and rooflight upstands.

What's included?

  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • Strip-out of the old covering, with waste taken away
  • Written workmanship guarantee, plus manufacturer guarantee registration where available
  • Deck check and replacement of soft or rotten boards

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 Worthing?

£1,750–£3,100 for a typical 18 m² garage roof in EPDM, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

How long does it take to fit an EPDM roof?

A single garage typically takes one to two days and an insulated extension roof two to three, weather permitting. Larger roofs, scaffold and complex details add time.

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.
