When you hire a roof inspector, what exactly are they examining? Understanding what a roof inspector looks for helps you evaluate the thoroughness of the inspection and understand the final report. Here’s a detailed list of the key items a professional will check.
Exterior Roof Covering: The inspector will examine the roofing material—whether asphalt shingles, metal, tile, or slate—for signs of damage and aging. For asphalt shingles, they look for granule loss, curling, cracking, and missing pieces. For metal, they check for rust, loose fasteners, and panel separation. For tile and slate, they look for cracks, chips, and slipped pieces. For the full exterior evaluation, see what a roof inspection includes.
Flashing and Penetrations: Flashing is the metal stripping that seals roof transitions—chimneys, vents, skylights, valleys, and walls. The inspector checks for corrosion, lifting, gaps, and improper installation. Flashing failures are a leading cause of leaks.
Gutters and Drainage: The inspector examines gutters, downspouts, and drainage patterns to ensure water flows away from the foundation. Clogged or damaged gutters can cause water to back up under the roof edge.
Attic and Interior: Inside the attic, the inspector looks for signs of moisture—water stains, mold, rot—and checks ventilation and insulation. They examine the underside of the roof deck for daylight penetration. Improper ventilation can shorten roof life.

Structural Elements: The inspector evaluates the roof’s overall slope, sagging, and structural integrity. They look for signs of movement or weakness that could indicate framing issues. For common problems found during these checks, see common roof problems found during inspections.
