Why choose EPDM rubber roofing in Westbury?

Choose EPDM in Westbury 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 and around Westbury, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on shops with flat-roofed rear stores below flats. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

For Westbury we use South West rates: £1,650–£2,900 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.

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?

  • Warm-roof insulation and vapour control layer where required
  • Strip-out of the old covering, with waste taken away
  • Deck check and replacement of soft or rotten boards
  • EPDM membrane fully bonded, in one sheet where the roof size allows

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.

EPDM rubber roofing in Westbury: questions

Do you cover Westbury?

Who checks building regulations for a flat roof in Westbury?

Where the work needs approval it goes to Wiltshire Council 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 Westbury?

£1,650–£2,900 for a typical 18 m² garage roof in EPDM, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

Can an EPDM roof be fitted in winter?

Yes, as long as the deck is dry. The adhesives are affected by cold and damp, so very cold or wet days can delay bonding, and the roof is kept temporarily weathertight between dry spells.
