Why choose a liquid-applied roof in Kingswood?
Choose liquid roofing in Kingswood 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.
Around Kingswood, flat roofs are common on low-rise post-war blocks of flats and on 1930s semis with flat-roofed garages and kitchen extensions. 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.

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.
