Roof Inspection – How to Do One
Learning how to inspect a roof can help Ontario homeowners identify roofing damage, storm-related issues, attic moisture problems, and warning signs before they become major roofing repairs. Roof inspections are one of the most important parts of long-term roof maintenance planning.
What to Check During a Roof Inspection
- Missing shingles or panels
- Flashing and roof penetrations
- Attic moisture and ventilation
- Storm and wind damage
- Ice dam warning signs
- Gutter drainage problems
Start Your Roof Inspection Safely
Before inspecting any roofing system, homeowners should prioritize safety. Many roofing inspections can begin from ground level using binoculars, camera zoom, or drone photography. Walking on steep, wet, snow-covered, or damaged roofing systems can be dangerous. Professional roofing inspections are often recommended after major storms or when structural damage is suspected.

Ground-Level Inspection
Inspect roof lines, missing shingles, damaged flashing, roof sagging, and visible debris from the ground whenever possible.
Check After Storms
Roof inspections are commonly recommended after strong wind, hail, heavy snow, or freezing rain events.
Use Caution on Roofs
Steep roofs, wet surfaces, and damaged roofing systems can become extremely dangerous without proper safety equipment.
What to Look for on the Roof Surface
During an exterior roof inspection, homeowners commonly look for roofing material damage, flashing problems, debris buildup, drainage issues, and signs of aging or storm-related wear. Different roofing systems may show damage differently depending on roofing material type.

Asphalt Shingle Damage
Look for curling shingles, missing shingles, granule loss, blistering, cracking, and exposed nail heads.
Metal Roofing Inspection
Inspect metal roofing systems for loose panels, damaged flashing, sealant issues, and signs of movement around roof penetrations.
Flashing & Vent Areas
Roof flashing around chimneys, vents, skylights, and valleys should be checked carefully for gaps or deterioration.

Inspect the Attic for Hidden Roof Problems
Attic inspections are an important part of roof inspections because many roof leaks and ventilation problems first appear inside the attic. Homeowners often check for moisture, mold, water stains, wet insulation, daylight penetration, and poor airflow.

Water Stains
Dark stains on wood, rafters, or insulation may indicate roof leaks or condensation problems.
Poor Ventilation
Improper attic ventilation can contribute to moisture buildup, mold growth, and ice dam formation.
Insulation Issues
Wet, compressed, or damaged insulation may indicate moisture intrusion or roof-related problems.
When Should Homeowners Inspect Their Roof?
Roof inspections are commonly recommended in spring and fall, after major storms, before selling a home, or when warning signs appear. Regular inspections help homeowners better understand roof condition, maintenance planning, and future replacement timelines.

Spring Roof Inspections
Spring inspections often focus on winter damage, ice dams, snow stress, and freeze-thaw roofing movement.
Fall Roof Inspections
Fall inspections help homeowners prepare roofing systems for snow, ice, and winter weather conditions.
After Severe Storms
Strong wind, hail, and freezing rain events may create hidden roof damage requiring professional evaluation.
