Choosing a roofer
Ask questions that reveal the complete roof system and work process. A new covering is only one part of a reliable replacement.
The short answer
The essential questions about diagnosis, structure, materials, ventilation, access, weather protection, guarantees and payment. Ask questions that reveal the complete roof system and work process. A new covering is only one part of a reliable replacement.
Start with what you can see from inside the property, ground level or a safe window. Do not climb onto the roof, lean out of a window or walk on a fragile covering. These steps give a roofer useful context without putting you at risk.
Start with this decision: Ask questions that reveal the complete roof system and work process. A new covering is only one part of a reliable replacement.
Collect safe photographs, dates and any earlier roof paperwork.
Ask what was inspected, what remains hidden and which professional decision is still required.
Choose the next action from written evidence rather than pressure or a guessed online price.
Why is replacement recommended?
Ask what evidence makes repair poor value and whether the problem affects one detail, one slope or the whole covering. Good buying decisions come from a clear diagnosis, written work description and safe access plan. Price only becomes comparable when two contractors are pricing the same result. In this case, the important question is whether the evidence supports a local action, wider investigation or no immediate roofing work. The answer should identify the relevant roof area and avoid promising what cannot be seen.
Ask for the answer in writing and keep it with the quote, photographs and invoice. If something changes, pause at a safe point and agree the new work before it is hidden. For why is replacement recommended?, ask for a practical next step, any safety or access limit and the documents you should retain. This makes the advice useful now and provides a record if the property, weather or work changes later.

Finish by checking that the proposed action connects to the original problem and that the quotation does not quietly omit the difficult part of the work.
Preparing for a useful roof check
Give the roofer the property type, town or postcode, the first sign you noticed and when it happens. Mention previous repairs, roof windows, solar panels, chimneys, extensions and anything that may make the roof hard to reach. Photographs taken safely from the ground or inside can help with the first conversation, but they cannot show every layer or confirm the full price.
A good roof check makes clear what can and cannot be seen. Ask which parts of the roof were checked, whether any areas could not be seen and what may only become clear when work begins. This helps the quote clearly explain what is included.
Questions worth asking before you approve work
What evidence or document confirms: why is replacement recommended??
What evidence or document confirms: what exactly will be installed??
What evidence or document confirms: how will the work be protected??
What evidence or document confirms: what records will i receive??
What is the safest useful next step for this property?
You should understand the recommended repair, how the roof will be reached and anything the quote does not include. Do not choose on price alone when two quotes cover different work.
