Why Do Nail Pops Appear on My Roof in Myrtle Beach?

Nail pops happen when roofing nails slowly back out of the decking and push up on the shingle above them. Heat and cooling cycles, moisture in the wood, nails that were not driven correctly, or soft decking can all cause it. A popped nail can tear the shingle and let water in, so it should be repaired.

What Does a Nail Pop Look Like?

From the ground it can look like a small bump or raised spot under a shingle. Up close, the nail head may be poking through or the shingle may be torn.

What Causes Nail Pops?

• Wood decking expanding and shrinking with heat and moisture.
• Nails that were under-driven or angled during installation.
• Soft or rotted decking that will not hold a nail.

Can Nail Pops Cause Leaks?

Yes. A raised nail can wear a hole through the shingle above it, and water follows the nail into the decking.

How Are Nail Pops Repaired?

A roofer removes or resets the nail, seals the hole and replaces the damaged shingle if needed. It is a common roof repair. If nail pops are everywhere, it may be a sign of decking problems that are best fixed during roof replacement in Myrtle Beach.
