What flat roof work do we do in Trowbridge?
Balconies and roof terraces
Balconies in Trowbridge are often re-waterproofed when the ceiling below starts to stain. On many older balconies, the membrane was laid under tiles or screed with no way to inspect it, so by the time the leak appears, water may have been tracking under the surface for a long time.
Torch-on felt roofing
For a commercial roof in Trowbridge, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.
Liquid-applied roofing
Where a building in Trowbridge has an older asphalt or concrete roof that is sound but tiring, a compatible liquid system can sometimes refresh it. The key is matching the primer and system to the substrate and dealing with any blisters, cracks or poor falls before the membrane goes on.

What flat roofs are typical in and around Trowbridge?
In a town like Trowbridge flat roofs are mostly on low-rise post-war blocks of flats and terraced streets with flat-roofed rear kitchens and bathrooms. Weather matters on a flat roof. 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 Trowbridge?
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.
