What Happens During a Professional Roof Inspection?

A professional roof inspection is part detective work, part preventive medicine. Knowing what happens during one helps you hire the right roofer, understand the report, and tell a thorough inspection from a sales pitch with a ladder. Here's the process, step by step.

1. Exterior ground assessment

The roofer starts from the ground: overall roofline (any sagging?), visible shingle condition, gutter and downspout state, chimney and vent condition, and signs of past repairs. This frames what they'll verify up close.

2. Roof surface examination

On the roof (with proper safety equipment), the inspector checks: shingle condition — bruising, cracking, curling, granule loss, missing tabs; seal integrity — gently testing whether tabs are still adhered; flashing at chimneys, walls, valleys, and penetrations; pipe boots and vent seals; ridge caps; and soft spots indicating deck damage. They'll note hail and wind patterns — random, directional damage versus uniform wear.

3. Attic and interior check

The underside tells the other half of the story: daylight through the deck, water stains on rafters or decking, damp or compressed insulation, ventilation adequacy, and any mold or mildew. Many leaks are diagnosed from inside, where water's path is visible.

4. The report and recommendations

A good inspection ends with a written report: photos of findings, condition assessment by area, prioritized recommendations (urgent / soon / monitor), and estimated remaining service life. Be wary of inspections that skip the attic, produce no photos, or jump straight to a full-replacement quote — that's a sales call, not an inspection.
