A flat roof replacement strips the old covering from a low-pitched roof and lays a new waterproof system, usually EPDM rubber, GRP fibreglass or torch-on felt, over a sound deck with correct falls, upstands, trims and outlets so rainwater drains away.
We offer a new flat roof across Warwickshire, and Warwick is one of the places we cover, along with nearby Leamington Spa, Kenilworth and Stratford-upon-Avon. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in the West Midlands it sits within £1,950–£4,400 including VAT.

How much does a new flat roof cost in Warwick?
Here is how the guide price for a new flat roof breaks down in Warwick. We start from national figures and adjust for the West Midlands, which comes out about 2% below the national guide. The resulting range, VAT included, is £1,950–£4,400, and a survey, at no cost to you, firms it up.
| Type of job | What it usually involves | Guide in Warwick |
|---|---|---|
| Small roof (up to 8m²) | A dormer, bay, porch or small garage roof re-covered in EPDM or GRP. | £800–£1,950 |
| Extension or garage (15–25m²) | A typical extension or single garage roof stripped and re-covered. | £1,950–£4,400 |
| Large or new warm roof | Larger roofs, or roofs needing a new deck and insulation build-up. | £3,900–£8,800 |
What moves the price up or down:
- Roof area and access to the roof
- Condition of the deck and joists underneath
- Insulation upgrades and changes to roof height at edges
- Number of rooflights, pipes and upstands to detail
What’s included?
- Survey of the covering, deck, falls, upstands and drainage

What are homes like around Warwick?
Stratford-upon-Avon and Warwick have timber-framed and Georgian buildings, and Leamington Spa is known for Regency stucco terraces and villas. Nuneaton and Bedworth have brick terraces from their mining and industrial past, Rugby mixes Victorian housing with large new estates, and southern villages near the Cotswolds use limestone and blue lias.
A moderate Midlands climate, but the Avon and its tributaries flood in places, and clay soils can move in dry spells.
If your house in Warwick fits one of these patterns, it helps us anticipate what a new flat roof will involve, though we always confirm the details on site.
Planning and building rules in Warwick
Because Warwick falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
Re-roofing a house with similar materials does not usually need planning permission in England. Listed buildings and conservation areas may need consent if the covering changes.
Replacing more than a quarter of a roof’s covering counts as renovation under Building Regulations, so the work is notified and the roof insulation may need upgrading. Bats are protected across the UK; if they roost under roof tiles, soffits or fascias, work stops and a licensed ecologist advises before it restarts.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Dates and permissions
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Build and hand over
Our trades complete a new flat roof while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

Questions about a new flat roof in Warwick
How much does a new flat roof cost?
Re-covering a typical 15–25m² extension or garage roof costs £1,950–£4,400. As a guide, allow around £75–£170 per square metre plus fixed costs for stripping, waste and access, with torch-on felt at the lower end and GRP or EPDM with new decking or insulation at the top. Small dormer and porch roofs cost less overall but more per square metre. We confirm a fixed price after the survey.
Why does water sit on my flat roof?
Ponding water on a flat roof is usually caused by inadequate falls, sagging joists, a deck that has dipped or blocked outlets. Small puddles that dry within a day or two are not always a problem, but standing water speeds up wear and finds any weakness. A new roof can be laid on firring strips or tapered insulation to create proper falls. We check falls during the survey.
Do I need planning permission in Warwick?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Warwick is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Can you combine a new flat roof with other work?
Yes. Because we manage several trades under one contract, we can plan a new flat roof alongside other work on your Warwick home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Can you repair my flat roof instead of replacing it?
A flat roof can often be repaired if the damage is limited to a small split, a failed joint or a loose upstand and the rest of the covering is sound. If the deck is soft, the covering is blistered or cracked across the roof, or leaks keep returning, replacement is usually better value. We assess the whole roof and give you an honest recommendation.
