Which flat roofs are common in Greater Manchester?

The climate is part of the brief. 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. Across Greater Manchester, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, newer estates where the first extension roofs are now being replaced and shops with flat-roofed rear stores below flats. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Greater Manchester?

Liquid-applied roofing

Liquid systems suit balconies and walkways in Greater Manchester because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

Balconies and roof terraces

Balconies in Greater Manchester 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.

GRP fibreglass roofing

Some Greater Manchester homeowners pick GRP for appearance alone. The topcoat comes in several colours, the trims are moulded to match, and the finished roof looks tidy from upstairs windows. With good laying conditions and a sound deck, a GRP roof typically lasts 20 years or more.

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.
