Roof Nail Pops: Why Raised Roofing Nails Can Cause Leaks
If you have noticed a small bump, raised spot, or exposed nail on your shingle roof, you may be looking at a roof nail pop. While it might seem like a minor cosmetic problem, a raised roofing nail can eventually create an opening where water gets into your roof system.
For homeowners in Northeastern Pennsylvania, addressing nail pops early can help prevent a small repair from becoming a much larger roofing problem.
What Is a Roof Nail Pop?
Roofing nails are used to secure asphalt shingles to the roof decking. Under normal conditions, those nails should remain firmly seated and covered by the roofing materials.
A nail pop occurs when a roofing nail begins to work its way upward. The raised nail can push against the shingle above it, creating a visible bump. In some cases, the nail head can become exposed.
Once that happens, water has an opportunity to work its way underneath the shingle.
Why Do Roofing Nails Pop Up?
Several things can contribute to nail pops. One common cause is movement in the roof decking or framing. Seasonal temperature changes can also cause roofing materials and wood components to expand and contract.
Moisture can play a role as well. If the decking becomes damp or deteriorates, fasteners may not remain as secure as they were when the roof was installed.
Improper installation is another possibility. Nails that are not driven correctly may be more likely to move over time.
Can a Nail Pop Cause a Roof Leak?
Yes. A raised nail can create a pathway for water beneath the shingles. Once moisture gets underneath the roofing material, it can reach the underlayment and roof decking.
The problem may not show up as an obvious ceiling leak right away. Water can travel along the decking before entering the attic or interior of your home.
That means a tiny bump on your roof could eventually contribute to damaged decking, insulation, drywall, or other parts of the home.
What Should You Do About Nail Pops?
Don’t simply hammer the nail back down and assume the problem is fixed. The surrounding shingle may already be damaged, and the nail may have popped because of an underlying issue.
A roofing professional can inspect the area, determine why the fastener moved, and make the appropriate repair. This may include replacing a damaged shingle, correcting the fastener, or inspecting the surrounding decking for moisture damage.
It’s especially important to address nail pops before Northeastern Pennsylvania’s heavy rain, snow, ice, and freeze-thaw cycles put additional stress on the roof.
