Photo-based inspection
A roof inspection should answer a practical question: is there a specific repair, a maintenance issue, a storm-damage concern, or a roof nearing the end of useful life?
What the contractor should check
The inspection should look at shingles or panels, ridge caps, pipe flashings, valleys, sidewalls, chimneys, gutters, roof edges, attic ventilation, visible decking issues, and interior leak clues when available.
For storm calls, photos matter. They create a record of hail marks, lifted tabs, missing pieces, dented metals, siding marks, and the roof slopes affected by the weather path.
Inspection timing around Illinois weather
Spring hail, summer wind, fall leaf buildup, winter ice dams, and freeze-thaw cycles all reveal different problems. A roof that looked fine in October can show eave leaks after a January thaw.
Older small-city housing stock and rental properties often benefit from an inspection before small leaks become drywall repairs. Farm and rural roofs need special attention to panel fasteners, tree exposure, and long unbroken roof runs.
What a useful inspection report says
The report does not need to be fancy. It should identify the issue, show relevant photos, explain urgency, describe repair or replacement options, and flag any hidden conditions that could change the quote.
When the roof is serviceable, that should be said plainly. When the roof is not a good repair candidate, the contractor should explain why with evidence.
