What drives the price of a roof
Roofing prices swing on a handful of factors: the material (asphalt shingles cost far less than metal or cedar), the size and pitch of the roof, whether the old roof is torn off or overlaid, how many existing layers there are, and how complex the job is — valleys, skylights, chimneys, and steep or hard-to-access roofs all add labour.
The condition of the decking underneath matters too. A reputable roofer inspects it and tells you up front that rotten boards may need replacing, rather than discovering a surprise mid-job.
Why the cheapest quote is often the most expensive
The lowest bid usually wins by leaving things out: overlaying the old roof instead of tearing it off, skipping new underlayment or flashing, or ignoring ventilation. Those omissions don't show on day one — they show up as leaks and premature failure a few years later.
How to compare roofing quotes fairly
Make sure every quote covers the same scope before you compare the numbers: tear-off and disposal, underlayment, flashing, ventilation, cleanup, and the workmanship warranty in writing. A quote that itemizes these is easy to trust; one that's a single lump sum with no detail isn't.
Pricing red flags
Be cautious of large upfront deposits, storm-chasing crews offering "today only" pricing, pressure to file or inflate an insurance claim, and quotes that skip the line items above. A trustworthy roofer is happy to put the full scope and payment schedule in writing.
Frequently asked questions
Why do roofing quotes vary so much?
Usually because they aren't quoting the same job. One may include a full tear-off, new underlayment, flashing, and ventilation, while a cheaper one overlays the old roof and skips key details. Always compare scope, not just the bottom line.
Should I pay a deposit for a roof?
A modest deposit toward materials can be reasonable, but be wary of demands for large upfront payments or full payment before the work is done. Tie payments to milestones and completion.
