EPDM rubber roofing in Johnstone

In Johnstone and across Renfrewshire, our teams fit EPDM rubber roofing to homes and small commercial buildings. The old covering is stripped, the deck is checked and repaired, insulation is added where the regulations call for it, and a new rubber membrane is bonded down with properly formed upstands and trims.

Why choose EPDM rubber roofing in Johnstone?

EPDM makes sense for a property in Johnstone when the roof is a straightforward shape, such as a garage or rear extension, and nobody needs to walk on it. A single sheet leaves few joins to fail, and because it is cold-applied there is no naked flame near timber fascias or a lived-in home.

In a town like Johnstone, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or 1960s and 1970s link-detached houses with flat-roofed garages and porches. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

When is EPDM the right choice, and when is another system better?

EPDM is a strong choice for simple domestic roofs that people do not walk on, such as garages, single-storey extensions, porches and dormers. It is less suited to roofs with regular foot traffic or many pipes and vents.

Where it does well: few or no joins on small roofs, flexible in cold weather, tolerant of minor building movement, and laid without a flame.

Where it falls short: the finish is plain dark rubber, it can be punctured by dropped tools or sharp debris, and it is not designed as a walking surface without added protection. Roofs with many penetrations take a lot of careful detailing.

If you want a hard, walkable finish or a complex shape, GRP fibreglass often suits better. On a tight budget, or a larger roof where a layered system is preferred, torch-on felt is worth pricing. Liquid-applied roofing handles awkward details and overlays, single-ply membranes are built for larger commercial roofs, and mastic asphalt belongs on older and heritage buildings. Our EPDM vs GRP vs felt guide sets them side by side.

What's included?

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

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

How much does an EPDM rubber roof cost in Johnstone?

£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at Scotland 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.

Does an EPDM roof need maintenance?

Very little. Clear leaves from outlets and gutters, look over trims and upstands once or twice a year and after storms, and keep foot traffic to a minimum.
