What flat roof work do we do in Salisbury?

Garage roofs

If your garage in Salisbury has an old cement sheet roof, it will eventually crack and let in water. Any suspected asbestos is tested and removed by a licensed specialist first, then the garage can be given new timbers, a deck and a modern membrane that should last for decades with sensible maintenance.

Torch-on felt roofing

Torch-on felt is widely specified for blocks of flats and HMOs, in Salisbury as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

GRP fibreglass roofing

If a flat roof in Salisbury has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

What flat roofs are typical in and around Salisbury?

In a town like Salisbury flat roofs are mostly on newer estates where the first extension roofs are now being replaced and lock-up garage blocks on estates. The climate is part of the brief. 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 Salisbury?

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.
