Why choose a liquid-applied roof in Caerleon?
If a flat roof in Caerleon is ageing but still dry, firmly bonded and on a sound deck, a reinforced liquid system can be applied over it. That avoids the cost and mess of a full strip-out, provided the moisture and adhesion checks at survey show the existing roof is fit to build on.
Caerleon's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on bungalows with flat-roofed side extensions and dormers too. 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.
How much does a liquid-applied roof cost in Caerleon?
For Caerleon we use Wales rates: £1,900–£3,000 is the guide for a typical 18 m² garage roof in a liquid-applied system, VAT included. The fixed price comes after a free survey for new and replacement roofs.

Do building regulations apply if a liquid coating goes over my roof?
They can. In England, Wales and Northern Ireland, re-covering more than half of a roof over a heated room is usually renovation of a thermal element, even when the new membrane goes over the old, so the roof should be insulated towards the renovation standard where feasible; for a Scottish property, the local building standards team will confirm whether a warrant is required.
A minor coating repair to a small area is different from re-covering the whole roof. Where insulation is needed, an overlay is not always practical, because the insulation has to go under a new waterproof layer. In that case we may recommend stripping to the deck, fitting a warm roof and applying the liquid system on top. Where approval applies, we deal with the paperwork; details are on the building regulations page.
What's included?
- Top coat with optional anti-slip finish, and guarantee registration where available
- Detailing of upstands, outlets, pipes and corners before the main area
- Primer matched to the substrate
- Fleece-reinforced liquid membrane applied to the specified thickness
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.

How much does a liquid-applied roof cost in Caerleon?
£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 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.
Can liquid roofing stop a leak on a flat roof?
It can, if the leak is at a detail or the membrane is worn but the roof beneath is sound. If water has soaked the insulation or deck, coating over it will not cure the problem.
