What Happens During a Professional Roof Inspection?
A professional roof inspection is more than a quick look from the ground. A thorough inspection examines the exterior surface, every penetration, and the attic environment to give you an objective picture of your roof's condition.
Exterior surface audit
The inspector examines shingle condition, looking for granule loss, curling, cracking, and impact damage. They check the ridge caps, hip shingles, and starter courses for proper installation and wear.
Valley metal, drip edge, and flashing are inspected for corrosion, lifting, and sealant failure.
Penetration and flashing review
Every penetration—plumbing vents, chimneys, skylights, and roof vents—is checked for flashing integrity and sealant condition. These are the most common leak sources.
Wall-to-roof connections and step flashing along chimneys receive close attention.
Attic ventilation and moisture check
From inside the attic, the inspector checks intake and exhaust ventilation balance, insulation levels, and signs of moisture or mold. Poor ventilation shortens shingle life and causes ice dams.
Moisture stains on the underside of the deck point to active or past leaks.
Photo documentation and report
A good inspection includes high-resolution photos of every concern and a written report with findings, estimated remaining lifespan, and recommendations.
This documentation is valuable for planning, resale, and insurance communication.
