About roof replacement

A full roof replacement is one of the biggest jobs a home ever needs. Picking the right roofer matters most here. A proper re-roof starts by stripping the old covering and checking the timbers underneath. The roofer then fits a new breathable layer and re-battens the roof. This work is hard to check once it's covered. So our roofers quote from a real survey, not a quick look from the ground. They list materials by name and sort out scaffolding and building rules. The work comes with a written guarantee, plus the maker's own warranty on materials.

How we help

Find Trusted Roofers is a national network that connects UK homeowners with local roofers. Since we are not a roofing contractor, we don't do the work ourselves. Instead, you tell us about your roof replacement job once. We then match you with a roofer in our network who covers your postcode and works on your roof type. Every roofer quotes from their own survey, and you deal directly with them and choose whether to proceed.

We check the roofers in our network against Companies House, and confirm public liability insurance. We also note any TrustMark, NFRC or CompetentRoofer membership. We verify what we can, although we don't guarantee the work itself. The work is always contracted directly between you and the roofer.

Roof Replacement — FAQs

How much does a new roof cost in the UK?

A typical three-bed semi re-roof in concrete tile runs roughly £6,500–£11,500 including scaffolding, while clay tile and natural slate cost more. Prices vary by roof size and access, and complex roofs, dormers and chimney details all add to the price. Always compare itemised quotes rather than single round numbers.

How long does a roof replacement take?

Most domestic re-roofs take 5–10 working days once scaffolding is up, weather permitting. Larger or more complex roofs, or houses with multiple valleys and dormers, can take two to three weeks.

Do I need planning permission to replace my roof?

Usually not if you're doing like-for-like. You may need permission if you change how the roof looks a lot. Conservation areas and listed buildings have stricter rules, and these often call for matching slate. Building rules still apply, and your roofer should handle that step.

How do I know my roof needs replacing rather than repairing?

Common signs point to a full replacement: wide underlay failure, tiles gone soft or split across the whole roof, and repeat repairs in different spots. Sagging battens are another warning sign. A roofer you trust will show you real photos from your own roof as proof either way.

What guarantee should I get with a new roof?

Expect a written workmanship guarantee of at least 10 years from the roofer. Manufacturer warranties on tiles and membrane often run 25 years or more. Insurance-backed guarantees are available and worth asking about.
