Which flat roofs are common in Merseyside?

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. Across Merseyside, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, terraced streets with flat-roofed rear kitchens and bathrooms 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 Merseyside?

Warm roof insulation upgrades

In a place like Merseyside, homeowners usually think about insulation when the roof covering is worn out. That is the right moment, because the thermal rules normally apply to a replacement over a heated room, and adding insulation then costs far less than doing it separately later.

Liquid-applied roofing

Choose liquid roofing in Merseyside when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.

Flats, HMOs and block roofs

Leaseholders in Merseyside want to see where their money goes. Our itemised quotes show each element of the job separately, including scaffold, insulation and provisional sums for hidden defects, which makes them easier to share and compare when the freeholder or agent is consulting on the work.

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.
