What is the average price of a new roof?

How much a new roof costs depends on the material used, whether you need scaffolding, and the roof’s size. A new tiled roof will typically cost £4,952.

Most roofs use tile or slate, and are either raised or pitched. Cement tile is usually cheaper than slate, because slate needs more materials to cover the rood (but tends to last longer).

How much do roof tiles cost?

The most common type of roof tiles are made from cement or clay and are a popular choice for modern homes. Cement tiles are cheaper, costing around 70p, compared to a clay tile which costs around £1.20.

The difference in price reflects the durability. Cement tiles normally last between 40-50 years while clay tiles are longer lasting, comfortably enduring 50-100 years of wear.

New roof with guttering

Gutters are a crucial part of your roof setup

New roof installation or repair?

It’s a good idea to have your roof and gutters checked once per year to assess whether any repairs are needed or, for more serious cases, to determine if you need to replace the entire roof.

Common repair situations might be when a household is experiencing leaks caused by a damaged or missing tile that may have blown off in the wind. In these cases, replacing your entire roof is not necessary and will only require a repair job to replace the tile. Learn more about roof repair costs.

For homes that experience extensive leaking to the point where their roof is failing to keep out water and is evidently damaged beyond repair, it’s a good idea to consider a complete replacement.

At this point, it might also be worth investing in new technology to make your home more eco-friendly for the future. Solar panels could be a good way to soften the blow of the cost by making a return on the new roof through lower energy bills.

What will affect the price of re-roofing?

There are a few factors that will affect the price of installing a new roof. If extensive work is carried out on a property of over one storey, scaffolding will be required, which will raise the price.

Other variables that will affect the price are the cost of the material, how easy it is to access the roof, the size, and the current state of the roof. Then there will be the costs for labour and the removal of waste.

Costs will be added if there are any unforeseen obstacles a roofer might run into during the project.

How do you get the best price?

When searching for the best price for your roof, it’s important to compare at least three companies and what they can offer you.

Ensure you ask about what other factors might drive up the cost – for example, if your property requires scaffolding which is expensive to assemble.

Ask each company you assess whether it’s viable to install slate tiles on your roof. This is the most popular material and has a long lifespan, which will provide you with longer term benefits.

How long will your new roof last?

Taking care of your roof with annual check-ups is one way to ensure it lasts longer by keeping the guttering clear and replacing any damaged or missing tiles.

It will also depend on what material your roof is made from. Cement tiles normally last between 40-50 years and clay are longer lasting with 50-100 years of wear. Natural slate has a longer lifespan, lasting 120 years or more.
