Liquid-applied roofing in Barnsley

Our liquid roofing service in Barnsley and across South Yorkshire covers overlays of sound roofs, full re-roofs with a new deck and insulation, and repairs to failing details. Every job starts with careful preparation, because a liquid membrane only performs when it is bonded to a clean, dry and stable surface.

Why choose a liquid-applied roof in Barnsley?

Liquid roofing suits a roof in Barnsley that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.

In and around Barnsley, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on low-rise post-war blocks of flats. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

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?

  • Detailing of upstands, outlets, pipes and corners before the main area
  • Fleece-reinforced liquid membrane applied to the specified thickness
  • Surface cleaning, repairs and removal of loose material
  • Survey of the existing roof, including moisture and adhesion checks

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 Barnsley?

£1,950–£3,100 for a typical 18 m² garage roof in a liquid-applied system, at Yorkshire and the Humber guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

What is a fleece-reinforced liquid roof?

It is a liquid membrane with a polyester fleece embedded between coats. The fleece adds strength, helps control thickness and resists cracking where the surface moves slightly.

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.
