Roof Inspection Cost Calculator
Most roofing contractors will inspect your roof free, and most of them are honest. But a free inspection is a sales call, and the person telling you that you need a new roof is the person who would sell it to you. An independent inspection costs $150–$400 and has no such conflict.

How we calculated your estimate
Inspection pricing scales with roof size, height and access difficulty, plus your local labor rates. Drone inspections cost less and see less; a physical inspection where someone walks the roof and enters the attic finds the things that matter.
Labor rates derive from published BLS occupational wage data. Read the full methodology →

Factors that affect the cost
Roof size & height
Bigger and higher roofs take longer and need more equipment.
Pitch & access
A steep roof needs harnesses. Some inspectors will not walk anything above 9/12 and will use a drone instead.
Report depth
A basic visual check is cheap. A written report with photographs, suitable for an insurance claim or a sale, costs more and is worth it.
Attic access
The best information is inside. An inspector who does not enter the attic is missing where leaks and ventilation problems actually show.
Ways to save money
Pay for independence when the stakes are high
If a contractor has told you that you need a $15,000 roof, a $300 second opinion from someone with nothing to sell is the best money you can spend.
Get an inspection before your warranty expires
Many manufacturer warranties have inspection requirements. Finding a covered defect at year nine is very different from finding it at year eleven.
Common mistakes to avoid
Treating a free inspection as impartial advice
It may well be honest — but it is structurally a sales call. Weigh it accordingly, especially when the recommendation is expensive.
Skipping the attic
Ventilation problems and early leaks show up inside long before they show outside. An inspection that never goes into the attic has looked at half the roof.
Frequently asked questions
An independent roof inspection costs $150–$400 depending on roof size, height and report depth. Most contractors will inspect for free — but that is a sales call, not impartial advice.
It can be useful, and most contractors are honest. But the person telling you that you need a new roof is the person who would sell it to you. When the recommendation is expensive, pay for a second opinion.
Annually, after any major storm, before buying a home, before a warranty expires, and whenever a contractor has told you something expensive that you want verified.
A good one covers the roof surface, flashing, valleys, penetrations, gutters — and the attic, where ventilation problems and early leaks show first. Insist on the attic.
They are cheaper and safer, and fine for a broad visual survey — but a drone cannot enter your attic or press on a soft spot in the decking. For a serious decision, get someone on the roof.
Not usually required, but some buyers and lenders ask for one. It certifies the roof has a certain number of years of life left, and costs $75–$200 on top of the inspection.
