Why choose a liquid-applied roof in Pencoed?

Liquid systems suit balconies and walkways in Pencoed because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

Around Pencoed, flat roofs are common on 1930s semis with flat-roofed garages and kitchen extensions and on newer estates where the first extension roofs are now being replaced. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

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.

What's included?

  • Survey of the existing roof, including moisture and adhesion checks
  • Primer matched to the substrate
  • Detailing of upstands, outlets, pipes and corners before the main area
  • Top coat with optional anti-slip finish, and guarantee registration where available

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

£1,900–£3,000 for a typical 18 m² garage roof in a liquid-applied system, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Is liquid roofing the same as a roof paint?

No. A proper liquid-applied membrane is built to a specified thickness and usually reinforced with fleece, while roof paints and simple coatings are much thinner and mainly used to extend the life of an existing covering.

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.
