Short answer: get one when you are told you need a full replacement after a single leak, when the quote is dramatically higher or lower than others, when the scope is vague, or when the diagnosis does not match what you are seeing.
Situations that genuinely warrant one
- Replacement recommended for one leak. Many leaks are a failed pipe boot or a flashing detail. If a contractor quotes a full roof on a localized problem, get another look.
- A quote far below the others. Usually scope, not generosity. Something has been left out.
- A quote far above the others with no explanation of what justifies it.
- Vague scope. If you cannot tell from the document what is being done, that is itself the problem.
- A tile roof quoted for full replacement. Often what is needed is underlayment replacement with the tile relaid, which costs substantially less.
- Pressure. Any urgency that comes from the salesperson rather than from your roof.
- A denied claim where you believe there is damage.
What a useful second opinion includes
- An actual roof walk, not a drive by
- Photographs of the specific areas in question
- A written assessment of condition and remaining life
- A clear repair versus replace recommendation with reasoning
- An itemized quote you can compare line by line
If a second opinion is just a different number with no explanation, it has not told you anything.
Comparing fairly
Put the quotes side by side on scope rather than total. Specifically check tear-off versus layover, decking allowance, new versus reused flashing, underlayment product, ventilation correction, permits and warranty terms. Our estimate guide walks through each line.
Also compare squares. If one quote shows materially less roof area, ask how it was measured.
What not to do
- Do not collect eight quotes. Two or three is informative, more is just noise.
- Do not share the other quotes to start a bidding war, because the easiest way to beat a price is to quietly remove scope.
- Do not assume the middle quote is automatically right.
We give them
We inspect and give second opinions regularly, including on other contractors' diagnoses, and a fair share end with us confirming the first contractor was right. That is a useful answer too.
