To cover exposed roofing nails, you need to seal them with roofing cement, caulk, or a metal cap to prevent water leaks and rust. Exposed nails are a common problem that can lead to serious damage if left alone. According to industry data, roof leaks are the reason 33% of homeowners pursue roof renovation or repair, and many of these leaks start at exposed nail holes. The good news is that fixing exposed nails is a simple job you can do yourself in just a few minutes.
Why Exposed Nails Leak
When roofers install shingles, they use nails to hold them down. Over time, nails can back out due to heat, cold, and wind. Water finds its way into these small holes and seeps into your attic and walls.
Exposed nails rust and create bigger holes. This makes the problem worse. You may see water stains on your ceiling or wet spots in your attic.

Use Roofing Cement to Seal Nails
Roofing cement is the best choice for sealing exposed nails. Buy a caulking gun and roofing cement at any hardware store. Apply the cement over the nail head and around the shingle. Let it dry for 24 hours before rain.
Roofing cement costs just a few dollars and lasts for years. It sticks to wet and dry surfaces, so timing is not critical. According to RubyHome (2025), the average roof replacement cost is $9,526, so preventing leaks with simple cement saves thousands of dollars in future repairs.
Other Ways to Cover Nails
You can also use metal caps or rubber washers over exposed nails. These are small shields that fit over the nail head. Some roofers use caulk mixed with roofing granules to match your shingles. Here are your main options:
| Method | Cost | How Long It Lasts |
|---|---|---|
| Roofing cement | $5-$15 | 10+ years |
| Metal caps | $0.50 each | 15+ years |
| Caulk | $3-$8 | 5-7 years |
When to Call a Pro
If you have many exposed nails or if your roof is steep, hire a roofer. According to the U.S. Bureau of Labor Statistics, the median hourly wage for roofers is $24.05, so professional help is affordable. A roofer can seal all exposed nails in one visit and spot other damage you might miss.
If your roof is very old, exposed nails may be a sign it needs replacement soon. According to RubyHome (2025), the average roof lifespan is 25 to 50 years. If your roof is near the end of its life, sealing nails is just a temporary fix. Consider planning a full roof replacement to avoid bigger problems later.
