Which flat roofs are common in West Midlands?
The climate is part of the brief. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds. Across West Midlands, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, 1930s semis with flat-roofed garages and kitchen extensions and low-rise post-war blocks of flats. Approximate 1991–2020 regional averages based on Met Office data.
Which flat roof jobs do we take on in West Midlands?
Liquid-applied roofing
Liquid systems suit balconies and walkways in West Midlands 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.
Extension and kitchen roofs
Ponding against the house wall is a common reason for replacing an extension roof in West Midlands. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.
Torch-on felt roofing
For a commercial roof in West Midlands, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.
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.
