Which flat roofs are common in South Yorkshire?

Weather matters on a flat roof. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county. Across South Yorkshire, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, 1960s and 1970s link-detached houses with flat-roofed garages and porches 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 South Yorkshire?

Flat roof surveys and leak tracing

Flat roofs in South Yorkshire hide their problems well. A covering can look fine while the insulation beneath it is wet or the deck is softening. A survey with moisture readings and core samples shows what's happening under the surface before it reaches the ceiling.

EPDM rubber roofing

Where an older flat roof in South Yorkshire has a sound structure but a tired covering, EPDM is a straightforward upgrade: strip, check the deck, add a warm-roof build-up if the room below is heated, and bond the new membrane. It also makes a good base for a sedum green roof.

Flat roof repairs

Small businesses in South Yorkshire with a flat-roofed shop, office or unit can't leave a leak running over stock or equipment. A repair stops the water at its entry point, and our inspection tells you whether the rest of the roof needs attention soon or can safely be left for now.

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.
