Types of Roof Replacement
Flat Roof Replacement
Flat roofs are common on extensions, garages, and some modern homes. The cost depends on the covering used, such as felt, EPDM, or GRP.
Pros
- Usually cheaper than a full pitched roof replacement
- Simpler shape can reduce labour time
- Good access on some properties
Cons
- Material choice matters a lot to lifespan
- Poor drainage or ponding can add complications
Best for: Garages, extensions, and homes with dedicated flat-roof sections
Pitched Gable Roof Replacement
A common roof style on many UK homes. Costs rise with roof size, tile choice, scaffolding, chimneys, and any structural repairs underneath.
Pros
- Widely understood by roofing contractors
- Broad choice of tile and slate finishes
- Strong long-term weather protection
Cons
- Scaffolding is usually essential
- Hidden timber or felt issues can add cost once opened up
Best for: Typical terraced, semi-detached, and detached homes with a standard pitched roof
Hip or More Complex Roof Replacement
Hip roofs and more complex roof forms usually need more labour, more cutting, and more material. Complex detailing also makes quotes rise faster.
Pros
- Strong weather performance when well built
- Can suit larger or more architecturally complex homes
Cons
- Usually more expensive than a simpler gable roof
- More labour-intensive detailing
Best for: Larger or more complex homes where the roof geometry is not straightforward
The overall cost is driven mainly by roof shape, size, materials, and how much structural or access work is needed around the main replacement.
What Affects the Cost
- Roof size in square metres
- Roof type, including flat, gable, hip, or more complex layouts
- Tile, slate, felt, EPDM, or GRP material choice
- Scaffolding, skip hire, and access constraints
- Condition of battens, underlay, and roof structure underneath
- Chimneys, valleys, roof windows, and flashing details
Labour Cost Breakdown
Labour is typically 30–50% of the total installation cost. The complexity of the job determines how long it takes.
What Is Usually Included
- Removal of the old roof covering
- Supply and fitting of new covering materials
- Standard battens and underlay where required
- Basic flashing and ridge detailing
- General site clean-up at the end of the job
Extra Costs to Expect
These aren't always required, but it's worth knowing about them before you get quotes.
Running Costs & Potential Savings
A new roof does not usually create direct bill savings in the same way as a heating upgrade, but it can help reduce water ingress risk, improve weather protection, and support insulation performance when the roof build-up is upgraded at the same time.

Frequently Asked Questions
How much does a new roof cost in the UK?
A full roof replacement can vary from a few thousand pounds for a small flat roof to well into five figures for larger pitched or more complex roofs.
What affects roof replacement cost the most?
Size, material, scaffolding, roof shape, and any hidden structural issues underneath are usually the biggest cost drivers.
Is a hip roof more expensive than a gable roof?
Usually yes. Hip roofs often need more labour, more materials, and more detailed work than a simpler gable roof.
Do roofers usually include scaffolding in the quote?
Sometimes, but not always. You should always check whether scaffolding is built into the quoted price or listed separately.
How long does a roof replacement take?
Small flat roofs can be finished quickly, while a full pitched roof replacement often takes several days to over a week depending on conditions and complexity.
Can hidden defects increase the final price?
Yes. Once the roof covering is removed, damaged battens, felt, or structural timbers can add extra cost that was not fully visible at survey stage.
