Detect Roof Underlayment Failure After Storms

Cost Savings

Checklist Tasks

• Examine attic ceilings for new stains or damp insulation after storms.
• Check for raised or uneven shingles showing underlayment displacement.
• Look for piles of roof granules in gutters revealing shingle damage.
• Inspect valleys and flashing for exposed, torn, or wrinkled underlayment.
• Probe attic roof deck with a blunt tool to find moisture-softened spots.
• Test rafters and sheathing using a moisture meter for concealed water.
• Check for daylight through attic roof boards indicating missing underlayment.
• Scan roof for nail pops or shifted fasteners that may tear underlayment.
• Look for mold or mildew odors in attic corners from slow leaks.
• Photograph all damage for insurance claims and repair tracking.
• Review wind speeds and hail size from recent storms for hidden risks.
• Arrange thermal imaging if there is suspected hidden moisture, but no obvious clues.
