Why choose EPDM rubber roofing in Falmouth?
Where an older flat roof in Falmouth has a sound structure but a tired covering, EPDM is a straightforward upgrade: strip, check the deck, add a warm-roof build-up if the room below is heated, and bond the new membrane. It also makes a good base for a sedum green roof.
In a town like Falmouth, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or low-rise post-war blocks of 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.

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?
- Deck check and replacement of soft or rotten boards
- EPDM membrane fully bonded, in one sheet where the roof size allows
- New drip and kerb trims, outlets and upstand details
- 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 Falmouth?
£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.
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.
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.
