Which flat roofs are common in Northumberland?

The climate is part of the brief. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification. Across Northumberland, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, lock-up garage blocks on estates and newer estates where the first extension roofs are now being replaced. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Northumberland?

EPDM rubber roofing

For landlords with property in Northumberland, EPDM's low upkeep is the main draw: once the outlets are kept clear and the trims are checked once or twice a year, there is little else to do. It also goes down quickly on a small roof, which keeps disruption for tenants to a minimum.

Liquid-applied roofing

Liquid roofing suits a roof in Northumberland that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.

Warm roof insulation upgrades

In a place like Northumberland, 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.

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.
