What flat roof work do we do in Westbury?

Commercial flat roofing

We are flat roof specialists, so a commercial roof in Westbury gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.

Torch-on felt roofing

On larger roofs in Westbury with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.

Extension and kitchen roofs

Condensation drives some replacements in Westbury. Older extension roofs were often built cold, with insulation between the joists and no reliable vapour control. Warm air from the kitchen reaches the cold deck, moisture builds up and the timber suffers. A warm roof deals with the cause, not just the stain.

What flat roofs are typical in and around Westbury?

In a town like Westbury flat roofs are mostly on lock-up garage blocks on estates and 1960s and 1970s link-detached houses with flat-roofed garages and porches. Rain and wind decide how a flat roof is detailed. 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. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Westbury?

Where approval is needed it goes to Wiltshire Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
