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.
In Nottinghamshire, we price a new flat roof against our guide for the East Midlands, £1,900–£4,300 including VAT, then adjust it once we have surveyed your home. We work across Nottingham, Mansfield, Worksop and Newark-on-Trent and the rest of the county or region. Planning and building control requirements follow the rules for England, and we look into your property's position before a written quote is sent.

How much does a new flat roof cost in Nottinghamshire?
Use the table to gauge the cost of a new flat roof in Nottinghamshire before we visit. Figures include VAT and are scaled for the East Midlands, coming out about 4% below the national guide, which gives £1,900–£4,300 overall. After a free survey, you receive a fixed written price.
| Type of job | What it usually involves | Guide in Nottinghamshire |
|---|---|---|
| Small roof (up to 8m²) | A dormer, bay, porch or small garage roof re-covered in EPDM or GRP. | £750–£1,900 |
| Extension or garage (15–25m²) | A typical extension or single garage roof stripped and re-covered. | £1,900–£4,300 |
| Large or new warm roof | Larger roofs, or roofs needing a new deck and insulation build-up. | £3,800–£8,600 |
The main things that change the figure:
- Roof area and access to the roof
- Covering system: EPDM, GRP or torch-on felt
- Condition of the deck and joists underneath
- Insulation upgrades and changes to roof height at edges
Scope of the work
- Survey of the covering, deck, falls, upstands and drainage
- Insulation upgrade to a warm roof build-up where agreed
- New EPDM, GRP or torch-on felt membrane laid to falls
- Upstands, flashings and drip edges finished neatly
- New trims, outlets and gutter connections
- Rooflights refitted or replaced where required
Housing across Nottinghamshire
Nottingham has large areas of Victorian red-brick terraces, with Edwardian villas in Mapperley and Sherwood and big interwar council estates. Mansfield, Ashfield and Worksop have brick terraces and post-war housing built for mining communities, while Newark and Southwell keep Georgian centres. New estates continue to appear around Nottingham and the larger towns.
Terraces commonly suit loft rooms, rear extensions and repointing. Interwar semis take side extensions and garage conversions, and older buildings in Newark or Southwell may need conservation-area window choices.
A moderate, fairly dry climate, but the Trent flood plain affects low-lying areas, and former coal workings can influence ground conditions.
Planning and building rules in Nottinghamshire
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Nottinghamshire comes under England, covered below, and we raise any questions with the council before your quote is finalised.
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
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new flat roof.
Your fixed price
After the survey we send a quote for a new flat roof that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
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.
How we work
Frequently asked questions
How long will a new flat roof take?
On a typical home, allow 1–3 days for most roofs. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Should I insulate my flat roof when it is replaced?
Replacing a flat roof is the most cost-effective time to add insulation, because the covering is already off. A warm roof, with insulation laid above the deck, keeps the structure warm and reduces condensation risk. Building regulations may require insulation when a large part of the roof is renewed. It raises the roof height slightly, which affects trims and upstands.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new flat roof, explain the options and answer questions. There is no charge and no obligation; afterwards we send a 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.
How long does a flat roof last?
A well-installed EPDM or GRP flat roof can last 25 years or more, while torch-on felt systems typically last around 15–25 years, depending on quality and exposure. Lifespan depends on correct falls, good detailing at edges and upstands, and keeping outlets clear. Foot traffic, ponding and poor ventilation shorten it. Annual checks help catch small problems early.
