Attic Insulation: Signs You Need a Top Up

A proper attic inspection looks beyond shingles and focuses on the entire roofing system. For homes in Ontario the following items are critical in Ontario’s climate:

• Measure existing insulation depth (most homes have only 5–7 inches)
• Confirm insulation meets Ontario’s recommended R-60 standard (approximately 17–22 inches)
• Check for uneven coverage, settling, or compacted insulation
• Identify moisture-damaged or mold-affected insulation
• Ensure insulation is properly installed without blocking ventilation pathways

• Verify balanced intake and exhaust ventilation
• Inspect soffit vents for blockages or insulation interference
• Check ridge vents, roof vents, or exhaust vents for proper airflow
• Confirm ventilation meets manufacturer requirements (GAF, Owens Corning, IKO, CertainTeed)
• Identify signs of heat or moisture buildup in the attic

• Inspect roof decking for condensation, staining, or rot
• Check nails and fasteners for rust or frost buildup
• Look for mold or mildew on wood surfaces
• Identify air leaks from bathrooms, kitchens, or attic hatches

• Confirm installer authorization on manufacturer websites
• Review ventilation compliance to protect shingle warranties
• Identify attic-related issues that could void manufacturer coverage
• Document conditions that may lead to premature roof aging

• Assess risk areas for ice dam formation
• Review attic heat loss related to freeze-thaw cycles
• Identify problem areas caused by heavy snow load and wind exposure

• Provide clear guidance on insulation upgrades to R-60
• Recommend ventilation improvements where required
• Outline steps to improve energy efficiency and roof longevity
• Flag urgent issues that could lead to leaks or warranty denial
