What Are Nail Pops?

Nail pops are raised or backed-out roofing nails that can lift shingles and create potential leak points.

Understanding Nail Pops

Nail Pops: Nail pops are raised or backed-out roofing nails that can lift shingles and create potential leak points.

Published: June 4, 2026 Reviewed: June 4, 2026 Updated: June 4, 2026 By Exterior Echelon

Nail pops are roofing nails that back out or push upward. They can lift shingles, create small humps, or expose areas where water can enter.

Why It Matters

Shingles rely on proper fastening. Raised nails can break the seal between shingles, loosen material, and create small but important leak risks.

Common Problems

Common issues include visible bumps, lifted shingles, exposed nail heads, fasteners driven too high or too low, and decking movement that pushes nails upward.

Exterior Echelon Notes

Exterior Echelon looks for roofing nail pops when inspecting roof condition because fastening issues often reveal installation quality and decking performance. Interior drywall nail pops are a separate topic from roofing nail pops.
