Most homeowners picture a roof inspection as someone glancing up from the front yard for a minute or two. A real inspection is a lot more thorough than that, and knowing what should actually happen helps you tell a genuinely useful inspection from a rushed one.
Before the Inspector Ever Climbs a Ladder
A good inspection usually starts on the ground, walking the perimeter of the house and looking up with binoculars, checking for anything obviously wrong before ever getting on the roof itself, missing or damaged shingles, sagging areas, or gutters pulling away from the fascia. This ground-level pass sets the direction for the rest of the inspection.
The Exterior Inspection
Once on the roof, the inspector focuses on the materials themselves, checking shingles or tiles for cracks, curling, blistering, or missing granules, and examining flashing around chimneys, vents, and skylights closely, since that's consistently the most common source of leaks. Structural elements like the roofline and any visible sagging get checked here too.
The Interior Inspection
Not all roof damage shows up from the outside. A thorough inspection includes going into the attic to check ceilings, walls, and insulation, and to look for water stains, active leaks, or mold that wouldn't be visible any other way. This is also where ventilation problems get caught, things like inadequate intake or exhaust airflow that can quietly shorten a roof's lifespan long before the surface shows obvious wear. A standard inspection isn't a structural engineering assessment, though. If you're weighing a switch to a heavier material like tile, our guide on whether a tile roof adds seismic risk covers when that separate step actually matters.
What 2026 Inspections Check That Older Ones Didn't
Inspections have expanded in scope recently. A thorough 2026 inspection increasingly checks whether current roofing materials meet California's Title 24 cool roof requirements, especially relevant if replacement is being considered. If the home has solar, the inspector should also look closely at the flashing and mounting points around the panels, an area covered in more detail in our piece on solar and roof replacement timing. Some inspections now also start with a drone roof inspection pass, capturing detailed aerial imagery of hard-to-reach areas before anyone sets foot on the roof itself.
How Long It Actually Takes
A traditional manual inspection, covering both the exterior and interior properly, typically takes 45 minutes to 2 hours, depending on the roof's size, slope, and how much needs closer attention. A drone-assisted inspection is often faster on site, with 30 to 60 minutes of flight time, though the imagery still has to be reviewed afterward before the report is finished.
What's in the Report
A useful inspection report is more than a verbal summary. It should include:
- Photo documentation of the roof's actual condition
- A detailed assessment of materials, flashing, and structural components
- Specific notes on chimneys, skylights, vents, and gutters
- Clear recommendations, repair now, monitor, or no action needed
This kind of documentation is also useful if you ever need it for an insurance claim, since it establishes exactly what condition the roof was in at a specific point in time.
Free vs. Paid Inspections
A free inspection, usually offered alongside a repair or replacement estimate, gives you a solid general assessment and is the right choice for most homeowners just trying to understand their roof's condition. An independent, paid inspection, typically 100 to 400 dollars, produces a more formal written report, which carries more weight in situations like a real estate transaction, an insurance dispute, or a legal matter where you need documentation from a neutral third party rather than a contractor's estimate.

Frequently Asked Questions
How long does a professional roof inspection take? +
A traditional manual inspection typically takes 45 minutes to 2 hours, depending on the roof's size, slope, and condition. A drone inspection is usually faster on site, often 30 to 60 minutes of flight time, though the report itself may take a few extra days to prepare.
What's the difference between a free and a paid roof inspection? +
A free inspection, usually offered alongside a repair or replacement estimate, gives you a general assessment. A paid, independent inspection, typically 100 to 400 dollars, produces a formal written report that carries more weight for insurance claims, real estate transactions, or legal disputes.
Does a roof inspection check the attic too? +
Yes, and it should. A thorough inspection includes the interior as well as the exterior, checking the attic for proper ventilation, insulation condition, and any signs of moisture or leaks that aren't visible from outside.
Do inspectors check for Title 24 cool roof compliance now? +
Increasingly, yes, especially for roofs being considered for replacement, since California's 2026 Title 24 code updates apply more broadly than before. A thorough inspection in 2026 should flag whether current materials meet those requirements.
What's included in a roof inspection report? +
A comprehensive report typically includes photo documentation, a detailed condition assessment of materials and flashing, notes on components like chimneys and gutters, and specific recommendations for repair or maintenance.
A proper inspection should leave you with a clear, documented picture of your roof's actual condition, not just a verbal "looks fine." If an inspector isn't checking the attic, isn't documenting what they find, or is done in five minutes flat, it's worth asking what exactly was actually covered.
