Liquid-applied roofing in Falmouth

Our liquid roofing service in Falmouth and across Cornwall 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 Falmouth?

Choose liquid roofing in Falmouth when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.

In and around Falmouth, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, and on shops with flat-roofed rear stores below flats. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

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?

  • 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
  • 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.

Who checks building regulations for a flat roof in Falmouth?

Where the work needs approval it goes to Cornwall Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

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

£2,100–£3,350 for a typical 18 m² garage roof in a liquid-applied system, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can liquid roofing be applied in the rain?

No. The surface must be dry, and most systems need a dry window while they cure. Some fast-curing products shorten that window, but the team will not apply onto a damp roof.

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.
