What does a dormer roof in Stratford-upon-Avon need?
Dormer roofs in Stratford-upon-Avon are often replaced when the loft room below starts to show damp, particularly along the back wall or around the window head. By then the deck may be wet, so a full rebuild with new insulation is usually the better choice than patching from a ladder.
Around Stratford-upon-Avon, flat roofs are common on 1960s and 1970s link-detached houses with flat-roofed garages and porches and on lock-up garage blocks on estates. 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 Stratford-upon-Avon?
Guide price in Stratford-upon-Avon: £1,400–£2,650 for an 8 m² GRP dormer roof including scaffold, including VAT at West Midlands rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Dormer (8 m²), GRP, scaffold | £1,400–£2,650 |
| Single garage (18 m²), EPDM rubber | £1,600–£2,800 |
| Extension (20 m²), GRP, new deck + insulation | £3,000–£5,400 |
Is GRP or EPDM better on a dormer roof?
GRP fibreglass is often the first choice on a dormer, because it is laid as a liquid resin over a mat and forms neat, rigid edges, corners and drip details on a small roof. It cures to a hard surface that copes with occasional foot traffic during window cleaning or maintenance.
EPDM rubber works well on a plain rectangular dormer and can usually be laid as one sheet, with no field joins. Unlike GRP, it does not depend on resin curing conditions on the day. Torch-on felt can be used, but working a torch close to timber cladding, fascias and tiles needs extra care, so a cold-applied system is often chosen instead.
We recommend the system after surveying the dormer, its edges and how it meets the main roof.

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.

Is a dormer roof cheaper than a garage roof?
Not by as much as the size suggests. Scaffold and the extra detailing at height mean a small dormer roof often costs about the same as a single garage roof.
