What flat roof work do we do in Preston?

Torch-on felt roofing

Torch-on felt is widely specified for blocks of flats and HMOs, in Preston 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.

Liquid-applied roofing

For businesses and landlords in Preston, a cold-applied liquid roof means no flame on site and, with some systems, a short cure time. That can make it easier to work around occupied buildings, tenants and opening hours than a system that needs hot works or a long strip-out.

Single-ply membrane roofing

Single-ply also works on an extension or garage in Preston if you want a light, clean finish in a pale colour. On small roofs it is usually adhered, and while it can cost more than EPDM, it gives the same welded seams and details found on commercial roofs.

What flat roofs are typical in and around Preston?

In a city like Preston flat roofs are mostly on shops with flat-roofed rear stores below flats and lock-up garage blocks on estates. Rain and wind decide how a flat roof is detailed. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Preston?

Where approval is needed it goes to Preston City 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.
