Liquid-applied roofing in Worcester

Our liquid roofing service in Worcester and across Worcestershire 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 Worcester?

Liquid roofing suits a roof in Worcester 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.

Worcester's flat roofs are mostly on lock-up garage blocks on estates, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms too. 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 Worcester?

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.

When is a liquid roof the best option, and when is it not?

A liquid roof is often the best option for roofs crowded with pipes, vents and upstands, for balconies and walkways, and for overlaying a structurally sound roof that is starting to fail. It is the wrong choice when the deck is rotten, the insulation is wet or the falls are badly wrong.

Advantages: continuous finish with no laps; forms details around pipes and odd shapes easily; cold-applied with no flame; can often go over felt, asphalt or concrete; some systems take foot traffic.

Disadvantages: higher cost per square metre than felt or EPDM; needs dry weather and careful thickness control; only as good as the surface it is bonded to; product quality varies widely across the market.

For a straightforward re-roof on a fresh deck, EPDM or GRP may offer better value. Larger flat areas suit torch-on felt or single-ply. On a sound mastic asphalt roof, a compatible liquid system can sometimes be applied over it. See also our guide to overlay or strip.

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
  • Survey of the existing roof, including moisture and adhesion checks
  • Primer matched to the substrate

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 Worcester?

£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.

Does a liquid roof smell when it is applied?

Some systems, particularly PMMA, have a strong odour during application, while many polyurethane and water-based products are milder. We tell you what to expect and plan around windows and vents.

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.
