Which flat roofs are common in North Ayrshire?
Flat roofs in North Ayrshire sit on 1930s semis with flat-roofed garages and kitchen extensions, bungalows with flat-roofed side extensions and dormers and lock-up garage blocks on estates. 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. Approximate 1991–2020 regional averages based on Met Office data.
Building standards in Scotland
In Scotland a building warrant is usually needed for alterations, structural work and new roofs; like-for-like repairs to a covering can be exempt. Section 6 of the technical handbooks sets a domestic roof benchmark of 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. In North Ayrshire the application goes to North Ayrshire Council (building standards). More on the rules.
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.

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.
Can you put a green roof on top of EPDM?
Yes. EPDM is often used under sedum, with a protection layer, drainage and growing medium laid on top. The structure must be able to carry the extra weight, which we check before quoting.
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.
