What does a dormer roof in Strood need?
Dormer roofs in Strood 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 Strood, flat roofs are common on lock-up garage blocks on estates and on shops with flat-roofed rear stores below flats. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a new dormer roof cost in Strood?
At South East guide rates, an 8 m² GRP dormer roof including scaffold comes to £1,550–£2,900 including VAT. The fixed price comes after a free survey for new and replacement roofs.

|---|---|

| Extension (20 m²), GRP, new deck + insulation | £3,300–£5,900 |
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.
What's included?
- New membrane, drip trims and back-edge abutment under the tiles
- Free survey of the dormer roof, cheeks and main roof junction

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.
