A professional roof inspection is the foundation for any sound roofing decision—repair, replacement, or insurance claim. Understanding what a good inspection includes helps you evaluate whether the contractor you're working with is doing the job properly.
What a thorough inspection covers
A complete inspection examines shingle condition across all slopes—granule coverage, sealing, surface defects, and impact evidence if storm damage is suspected. It checks all transitions and penetrations: flashings at chimneys, skylights, and walls; pipe boots; drip edge condition; valley construction. It also evaluates gutters, soffit, fascia, and ideally includes an attic check for ventilation, insulation coverage, and evidence of moisture or prior leaks.
What an inspection report should include
A useful inspection report is photo-documented. Every finding should have a corresponding photograph showing the location and condition. The report should distinguish between existing wear, current functional issues, and immediate repair needs. Items that need attention should be described in terms of what they are, not just that they're a problem.
Inspection vs. estimate
An inspection determines condition. An estimate is a price proposal based on that condition. Contractors who skip inspection and go directly to an estimate are pricing from assumptions, not evidence. If a contractor arrives and within 10 minutes hands you a replacement quote without walking the roof, that's a drive-by estimate—not an inspection.
When to get an inspection
After any storm event that included hail or high wind. When buying or selling a home. When a roof is 10+ years old with no recent professional evaluation. When interior ceiling stains appear. When gutters show significant granule accumulation during cleaning.
Frequently asked questions
How long does a roof inspection take?
A thorough inspection of a standard single-family home takes 30-90 minutes depending on roof complexity, attic access, and how many findings are documented with photos.
Do I need to be home for a roof inspection?
For exterior inspection, no—though being present allows you to ask questions and see findings in real time. For attic access, interior access may require your presence.
Should I pay for a roof inspection?
Many roofing contractors offer free inspections as part of the estimate process. For a pre-purchase inspection or one independent of a contractor relationship, a paid inspection from a certified inspector ensures independent findings not influenced by a sales relationship.
