Which flat roofs are common in Perth and Kinross?
Flat roofs in Perth and Kinross sit on newer estates where the first extension roofs are now being replaced, shops with flat-roofed rear stores below flats 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 Perth and Kinross the application goes to Perth and Kinross Council (building standards). More on the rules.
When is a liquid roof the best option, and when is it not?
A liquid roof is often the best option for roofs crowded with pipes, vents and upstands, for balconies and walkways, and for overlaying a structurally sound roof that is starting to fail. It is the wrong choice when the deck is rotten, the insulation is wet or the falls are badly wrong.
Advantages: continuous finish with no laps; forms details around pipes and odd shapes easily; cold-applied with no flame; can often go over felt, asphalt or concrete; some systems take foot traffic.
Disadvantages: higher cost per square metre than felt or EPDM; needs dry weather and careful thickness control; only as good as the surface it is bonded to; product quality varies widely across the market.
For a straightforward re-roof on a fresh deck, EPDM or GRP may offer better value. Larger flat areas suit torch-on felt or single-ply. On a sound mastic asphalt roof, a compatible liquid system can sometimes be applied over it. See also our guide to overlay or strip.

Is liquid roofing good for balconies?
Often, yes. It forms neatly around railings, door thresholds and drains, and some systems take foot traffic. A new balcony or roof terrace generally needs planning permission, so check before converting a roof.
What is a fleece-reinforced liquid roof?
It is a liquid membrane with a polyester fleece embedded between coats. The fleece adds strength, helps control thickness and resists cracking where the surface moves slightly.
Does a liquid roof smell when it is applied?
Some systems, particularly PMMA, have a strong odour during application, while many polyurethane and water-based products are milder. We tell you what to expect and plan around windows and vents.
