What should I do if a roofer says my whole roof needs replacing?
For an expensive full replacement, ask the roofer to show why repair is no longer economical using photographs or inspection evidence. Unless the failure is obvious and urgent, obtaining another professional opinion can help confirm whether complete replacement is justified.
Ask for the evidence
A recommendation to replace an entire roof should come with reasons: what has failed, where, how widespread it is, and why repair is not a sensible option. Photographs of the areas of concern make that conversation straightforward.
If the reasoning is limited to the roof's age or to defects you cannot see, it is fair to ask for more.
Getting a second opinion
Seeking another assessment is normal and reasonable, particularly where the recommendation followed an unsolicited approach or an inspection you did not arrange.
An independent inspection that produces photographs and a written summary gives you something concrete to compare quotations against.
