Liquid-applied roofing in Clydach

A free survey comes first, including checks for trapped moisture and adhesion, so we can tell you plainly whether your roof can be overlaid or should be stripped. A fixed written quote follows.

Why choose a liquid-applied roof in Clydach?

If a flat roof in Clydach 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.

Clydach's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on lock-up garage blocks on estates 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 Clydach?

For Clydach 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.

Can a liquid roof go over my existing roof, and what preparation is needed?

Yes, if the existing roof is dry, firmly bonded and sitting on a sound deck. A liquid membrane is only as good as what lies beneath it, so we test the old roof before agreeing to overlay it.

At survey we check for:

  • Trapped moisture: soft spots, blisters or wet insulation mean the roof should be stripped, because water sealed in will cause new blisters and decay.
  • Deck condition: any sponginess or deflection needs repair first.
  • Adhesion: on felt and asphalt, loose areas are cut out and patched, and the existing surface must take the primer properly.
  • Falls and ponding: a coating follows the roof as it is. If water ponds now, it will pond on the new surface too unless the falls are corrected.

Preparation then follows: loose chippings removed, the surface cleaned and left to dry, blisters cut back and repaired, cracks filled, and the right primer applied. On older felt, mineral surfaces may need extra cleaning to give a good bond. Where the tests fail, we say so plainly and quote for a strip and re-roof. Read more on ponding water.

What's included?

  • Top coat with optional anti-slip finish, and guarantee registration where available
  • 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

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.

Who checks building regulations for a flat roof in Clydach?

How much does a liquid-applied roof cost in Clydach?

£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.

How long does a liquid roof take to cure?

That depends on the product and the weather. Some systems are rain-resistant within an hour or so, others take longer, and full cure can take a day or more in cool weather.

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.
