Why choose EPDM rubber roofing in Bootle?
If your Bootle 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 and around Bootle, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, and on shops with flat-roofed rear stores below flats. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.
How much does an EPDM rubber roof cost in Bootle?
For Bootle we use North West rates: £1,500–£2,650 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 | £1,500–£2,650 |
| Extension (20 m²), EPDM, new deck + insulation | £2,650–£4,650 |
| Porch or bay (4 m²), EPDM | £700–£1,200 |
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
- Warm-roof insulation and vapour control layer where required
- Strip-out of the old covering, with waste taken away
- 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.

How much does an EPDM rubber roof cost in Bootle?
£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at North West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
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.
Can you walk on an EPDM roof?
Occasionally, for maintenance, yes, but EPDM is not designed as a regular walking surface. Where you need a route to plant or windows, walkway pads can be bonded on, or GRP may be a better fit.
