Liquid-applied roofing in Willenhall

Liquid membranes give Willenhall 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 Willenhall?

Where a building in Willenhall has an older asphalt or concrete roof that is sound but tiring, a compatible liquid system can sometimes refresh it. The key is matching the primer and system to the substrate and dealing with any blisters, cracks or poor falls before the membrane goes on.

In and around Willenhall, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on shops with flat-roofed rear stores below flats. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.

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

At West Midlands guide rates, a typical 18 m² garage roof in a liquid-applied system comes to £2,050–£3,250 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?

  • Surface cleaning, repairs and removal of loose material
  • Survey of the existing roof, including moisture and adhesion checks
  • 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 England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

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

£2,050–£3,250 for a typical 18 m² garage roof in a liquid-applied system, at West Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

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.
