Does my roofer have to give me paperwork guarantees?

There is no law that forces every roofer to hand over a formal written guarantee, but you are protected by your consumer rights: work should be carried out with reasonable care and skill, and materials should be as described and fit for purpose. A reputable roofer will be happy to put the key points in writing.

In practice, you should expect a clear written quote before the work, and once it is done, paperwork covering what was carried out. Many manufacturers also offer guarantees on specific materials, such as flat-roof membranes, which the installer registers on your behalf.

What matters most is that everything is agreed in writing before work begins: the scope, the materials and the price. That written record is what protects both sides if any question comes up later.

If a roofer is reluctant to put anything in writing or give you a proper quote, treat that as a warning sign. We always set the job out clearly in writing and keep you informed from the first visit to sign-off.
