If your roof needs work, getting more than one quote is sensible. But quotes often aren’t easy to compare. One roofer suggests a small repair, another a new roof. Prices vary widely. Some quotes are a single line, others run to pages.
This guide explains what a good quote should include, how to compare like with like and the warning signs to watch for, especially from roofers who knock on the door.
Get quotes in writing
Always get quotes in writing. A clear written quote should say:
- exactly which parts of the roof will be worked on
- what will be done to each part, for example refix, replace or renew
- the materials to be used, including underlay and flashings
- how access will be provided, such as scaffolding
- how waste will be removed
- the total price, and whether it includes VAT
- how long the job should take
- what warranty, if any, is offered on the work.
Comparing like with like
Quotes differ mostly because roofers have seen different problems, or suggest different fixes. Before comparing prices, line up what each quote covers. Does one include the chimney flashings and the other not? Is one replacing the underlay? Does one include scaffold and the other leave it out?
It also helps to ask whether the price is fixed or an estimate, and what happens if more damage is found once the roof is opened up. A clear answer to that question, in writing, avoids arguments later.
If the scopes are very different, ask each roofer why. A good roofer will explain their reasoning and show you photos of what they found.

Warning signs of a doorstep roofer
Be cautious if someone:
- knocks on the door saying they’ve noticed a problem with your roof
- pressures you to agree to work today, or says the price is only for today
- asks for a large payment upfront or cash only
- won’t give a written quote or a full address
- goes onto your roof without being asked, then shows you damage
- finds more and more problems once work has started.
You don’t have to let anyone onto your roof. Take their details, close the door and get independent advice.
How an independent report helps
An independent roof report gives you a written record of what’s wrong, with photographs, and recommendations prioritised by urgency. You can send the same report to each roofer and ask them to quote for the items in it. That makes quotes easier to compare and helps you spot work that isn’t needed or items that have been missed.
Our report doesn’t include repair cost estimates, and it doesn’t recommend a particular roofer. It describes the condition of the roof. See what our survey covers.
Checking the work afterwards
When the work is finished, check it against the quote before final payment. Ask for photos of hidden work such as underlay and flashings. Our new roof snagging checklist lists what to look for. A new roof snagging inspection can check the work independently.
To get a written picture of your roof before asking for quotes, book a roof survey or get in touch.
Quick answers
How many roofing quotes should I get?
Two or three written quotes for the same scope is common. More quotes help less than making sure each one covers the same work.
Should I pay a deposit to a roofer?
Be wary of large upfront payments, especially cash. Agree payment terms in writing before work starts.
Is the cheapest quote always the worst?
Not always. The question is what each quote includes. A low price for a full scope is fine; a low price that leaves out key work is not.
Can I use your report to get quotes?
Yes. Many owners send the report to roofers so each quote covers the same defects.
