Why Does My Roof Make Popping Noises at Night?

Popping noises from your roof at night are usually caused by thermal contraction. As the roof cools after a warm day, wood decking, rafters and metal parts shrink slightly and shift, making popping or cracking sounds. It is often harmless, but poor attic ventilation can make it worse, and new or unusual noises are worth an inspection.

Why Does the Roof Pop as It Cools?

Materials expand in the heat of the day and contract as temperatures drop at night. Where boards, nails and metal meet, that movement can make noise.

Can Ventilation Make It Worse?

A poorly vented attic gets hotter during the day, so the temperature swing at night is bigger. See signs of attic ventilation problems.

When Should I Worry?

• Noises along with a sagging roofline.
• New sounds after a storm.
• Creaking along with ceiling cracks or stains.
