Why choose a liquid-applied roof in Chapel Allerton?

Choose liquid roofing in Chapel Allerton 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 Chapel Allerton, flat roofs are typically found on lock-up garage blocks on estates, and on terraced streets with flat-roofed rear kitchens and bathrooms. 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
  • Primer matched to the substrate
  • Survey of the existing roof, including moisture and adhesion checks
  • 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 Chapel Allerton?

£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.

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.

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.
