What does a dormer roof in Smethwick need?
A dormer roof that has been patched several times in Smethwick often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.
In and around Smethwick, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on low-rise post-war blocks of flats. 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.
How much does a new dormer roof cost in Smethwick?
For Smethwick we use West Midlands rates: £1,400–£2,650 is the guide for an 8 m² GRP dormer roof including scaffold, VAT included. The fixed price comes after a free survey for new and replacement roofs.

Do I need building regulations approval for a dormer roof?
Usually, yes, if you are replacing most of the roof. A dormer roof sits over a heated room, so it counts as a thermal element, and renovating more than half of it normally means upgrading the insulation where feasible.
In England the renovation target is 0.16 W/m²K for homes, approved through building control or a competent person scheme. Wales usually needs approval for most re-roofing work. Scotland works through the council's building standards and, where required, a building warrant. Northern Ireland asks you to contact district council building control before starting.
Insulating above the deck raises the roof slightly. On a dormer, that extra height has to fit under the main roof tiles at the back edge, so the build-up is planned at survey. Re-covering a dormer that looks the same afterwards does not usually need planning permission, but a listed building or conservation area may bring extra controls. More on our building regulations page.
What's included?
- Strip-out of the old covering and deck repairs

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.
