Do you get a guarantee with a new roof in the UK?
Yes, a reputable roofing company in the UK should offer a guarantee on a new roof, covering both materials and workmanship for a set number of years. This protects you if something goes wrong, whether that’s a leak or tiles working loose. We’ll look at how long guarantees usually last, what they cover, and what a full reroof tends to cost.
How long should a new roof be guaranteed for in the UK
Most established roofers offer a workmanship guarantee of around 10 years on a full reroof, though this can vary between 5 and 25 years depending on the company and the materials used. Manufacturer guarantees on the materials themselves, such as tiles or membranes, often run separately and can last considerably longer.
It’s worth getting the guarantee in writing before work starts, including what it actually covers. A good guarantee should detail what happens if a leak develops, whether call outs are free within the guarantee period, and whether it’s transferable if you sell the property.
How much does it cost to reroof a 3 bed house
For a typical three bedroom semi-detached property, a full reroof generally costs between £5,000 and £8,500 with standard concrete tiles, including scaffolding, removal of the old roof, new felt and battens, and reinstating the tiles. Detached houses or those with more complex roof shapes tend to sit at the higher end.
If you’re upgrading to slate or clay tiles, expect the cost to rise, sometimes significantly, but these materials often come with longer guarantees and a longer expected lifespan, which can make them better value over time. A detailed quote should break down labour, materials, scaffolding, and waste removal separately.
Should a new roof come with a warranty
Absolutely, and it’s one of the first things to ask about when getting quotes. A warranty gives you peace of mind that if something fails within the covered period, whether that’s the roofer’s workmanship or a manufacturing fault with the materials, you won’t be left covering the cost yourself.
Be cautious of any roofer who seems reluctant to put a guarantee in writing, or who only offers a very short period like 1 or 2 years. A confident, established roofer will usually be happy to back their work for a decade or more.
Do roofers guarantee work
Most legitimate roofing companies do guarantee their work, and many are members of trade bodies that offer additional insurance backed guarantees on top of the company’s own. This means that even if the roofing company were to close down, the guarantee could still be honoured through the insurance scheme.
Always check whether a guarantee is insurance backed, particularly for larger jobs like a full reroof. It’s a small detail that makes a real difference if anything ever goes wrong years down the line.
What a good guarantee should include
A solid roofing guarantee should clearly state the length of cover, what’s included (leaks, slipped tiles, flashing issues), and whether there’s a charge for call outs within that period. It should also specify whether the guarantee covers labour only, materials only, or both.
Ask for everything in writing, including the company’s registration details, before any work begins. A written guarantee with clear terms is far more valuable than a verbal promise, especially if you ever need to refer back to it.
What happens if a problem occurs during the guarantee period
If a leak or other issue appears within the guarantee period, contact the roofing company directly with photos and a description of the problem. A reputable roofer will arrange to inspect and fix genuine workmanship issues at no extra cost, usually within a reasonable timeframe.
| Guarantee Type | Typical Length |
|---|---|
| Workmanship guarantee | 5-25 years |
| Manufacturer material guarantee | 15-50 years |
| Insurance backed guarantee | 10 years (varies) |
Knowing the difference between these guarantee types helps when comparing quotes, since a longer headline figure isn’t always covering the same thing as a shorter one from another company.
A new roof is a big investment, so a clear, written guarantee from a trustworthy roofer is just as important as the price you’re quoted. Always ask what’s covered, for how long, and whether it’s insurance backed before signing anything.

Can I add guttering work to a reroof at the same time?
Yes, many homeowners take the opportunity to replace guttering, fascias, or soffits while scaffolding is already up, which can save on access costs.
What questions should I ask before agreeing to a reroof?
Ask about the guarantee length and what it covers, whether it’s insurance backed, the expected timeline, and what’s included in the price versus what might be extra.
