Liquid-applied roofing in Neath

Liquid membranes give Neath property owners a jointless, cold-applied roof without laps or separate flashings. They are especially useful around pipes, rooflights and tight corners where sheet systems need lots of cutting. If the roof below is wet or rotten, we say so and quote for the right fix instead.

Why choose a liquid-applied roof in Neath?

For businesses and landlords in Neath, a cold-applied liquid roof means no flame on site and, with some systems, a short cure time. That can make it easier to work around occupied buildings, tenants and opening hours than a system that needs hot works or a long strip-out.

Around Neath, flat roofs are common on shops with flat-roofed rear stores below flats and on low-rise post-war blocks of flats. 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 Neath?

At Wales guide rates, a typical 18 m² garage roof in a liquid-applied system comes to £1,900–£3,000 including VAT. 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?

  • Fleece-reinforced liquid membrane applied to the specified thickness
  • Surface cleaning, repairs and removal of loose material
  • 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.
