Professional Roof Inspection: A Homeowner's Guide

Most homeowners wait for a roof problem to announce itself. A drip after rain, a brown ceiling spot, a neighbor replacing their roof sooner than expected. The better moment to act is earlier — while the roof is still doing its job and the fixes are still manageable.

Types of inspections

Standard visual and physical: an inspector on the roof, walking, probing, and documenting. Best baseline for most PA homes.

Drone inspection: fast coverage of steep or fragile roofs, high-resolution photos, safer for the inspector. Good complement, not always a full replacement for hands-on.

Infrared: finds trapped moisture inside the roof assembly. Useful for flat commercial roofs and after suspected leaks.

The checklist

Structural: sagging, deflection, deck integrity, framing at penetrations.

Material: shingle wear, granule loss, curling, cracked flashing, sealant failure at vents and chimneys.

Interior: attic staining, daylight through decking, insulation moisture, ventilation.

Workmanship: nail placement, valley detail, drip edge, ridge cap seating.

Cost and what a real report includes

In Pennsylvania, a residential inspection typically runs $150 to $450. A useful report includes photos of every finding, plain-language severity, and a repair-vs-monitor recommendation for each item. If all you get is a one-page quote, that's a sales visit, not an inspection.

Choosing a qualified inspector

Green flags: written product specifications, proof of insurance, written scope, and a report format they can show you before you book.

Red flags: free 'inspections' tied to hard sales pitches, no photos, and reports that push replacement without documenting failure.
