Should a roofing quotation explain the cause of the problem?

The short answer

Yes. A quotation that only lists work tells you what will be done but not why, which makes it impossible to judge whether the scope is right. One that names the defect, its likely cause and the area affected lets you compare like with like, and lets you tell afterwards whether the problem was actually addressed.

What could this mean?

This also protects you later. If the leak returns, a quotation that named the cause shows what was and was not addressed.

What should you be shown before agreeing to the work?

The defect identified, described specifically rather than generically
Its likely cause
The roof area affected
The proposed repair and why it suits that cause
Anything the contractor could not see or access

Not every job needs every item. The point is that whatever is recommended should be supported by evidence you can see and a scope you can read.

Roof RepairsA roof repair fixes a localised fault — slipped slates, cracked tiles, failed flashing, a leaking valley or a split flat-roof seam — without replacing the whole roof. Most Cumbrian domestic repairs are completed in a single visit once the true cause of the leak has been identified.

What should you do next?

Ask for one sentence in writing: what has failed, and why. Most reputable contractors provide it without hesitation.
