The cost of a new roof varies considerably.
Roof replacement costs for an average sized three bedroom semi-detached house are likely to be anywhere between £5,000 – 15,000.
If only tiles, felt and battens are replaced it’s likely to be at the lower end of that scale. If significant work is required on the structural elements of the roof (e.g. the underlying timber structure) the price may be towards the higher end.
Flat roof replacement costs are lower.

What is the cost of a new roof?
A new flat roof will cost around £1,500 – 3,000, while a new pitched roof is more expensive, generally costing upwards of £5,000.
When working out how much does a new roof cost, it’s important to consider several factors including the roof type, size and which material you’ll be using.
Below is the cost per metre squared (m²) of the UK’s six most popular types of roofing material.
Roofing felt is the most affordable material costing £40m², and prices range up to £90 for premium GRP fibreglass.
In the cost table below, we’ve included the average UK roof size of 75m² to give you an idea of how much does a new roof cost depending on the material you choose.

There are several additional factors to look out for when calculating the cost of a new roof. Firstly, pitched roofs cost more due to the additional materials used during installation and taking more time to install, increasing labour costs.
Speaking of labour costs, a professional roofer will charge around £200 per day, with the average roof taking three days to install. Other potential costs depend on the amount of damage your current roof has sustained.

If your new roof is going to be pitched, it’s also worthwhile to consider the cost of replacing roof felt under tiles. While flat roofs often use roofing felt as their primary material, pitched roofs use felt as an underlay for other materials such as tiles for better protection from the weather.
However, you don’t necessarily need to get new felt at the same time as the rest of a new roof.
If the insulation of your current roof has been damaged, there may be a roof insulation cost added to your final bill. The cost will depend on how much extra insulation is needed.
What are the additional costs of a new roof to consider?
Depending on if you want any extras as part of a new roof, there are several considerations that may increase cost.
If your house is large, professional roofers may require scaffolding to reach places that they can’t with ladders. Scaffolding can cost around £600 depending on how much is needed.
Also, if you’re considering installing a loft conversion or skylight as part of your new roof, this will add a substantial cost.
