For homeowners and builders near the ocean, selecting the right roofing nails is pivotal. Coastal environments present unique challenges due to their high salt and moisture content. This article provides a comprehensive look at the considerations and best practices when choosing asphalt shingle roofing nails for homes close to the sea.
1. The Coastal Challenge
Coastal regions have a salty atmosphere, which can accelerate metal corrosion. As roofing nails are exposed to this environment, there’s a heightened risk of rusting, compromising the nail’s integrity and the overall roof’s lifespan.
2. The Ideal Material
For coastal homes, the primary consideration should be the nail material. Here’s a breakdown:
- Galvanized Steel: Treated with a layer of zinc to prevent rusting. However, in salty environments, even galvanized nails can corrode over time.
- Stainless Steel: Highly resistant to corrosion, making it an ideal choice for homes near the ocean. Though more expensive, their longevity and durability justify the cost.
- Aluminum: Another corrosion-resistant option, but less durable than stainless steel.
- Copper: Highly durable and corrosion-resistant, but its cost can be prohibitive for some.
Of these, stainless steel nails emerge as the top recommendation for coastal applications.
3. Nail Length and Size
For asphalt shingles:
- Recommended nail length is at least 1 inch (25 mm).
- The nail should penetrate 3/4 inch into the roof deck or go through the decking entirely if it’s less than 3/4 inch thick.
4. Consider the Underlayment
Beyond nails, a salt-resistant underlayment can further protect your roof from moisture infiltration and salt damage. Synthetic underlayments are especially popular for their water and salt resistance.
5. Maintenance and Inspection
Regular inspection is key:
- Visual Check: At least once a year, inspect for any visible rust or corrosion on nail heads and nearby shingles.
- Professional Inspection: Have a roofing professional inspect every 3-5 years. They can identify and address minor issues before they escalate.
Conclusion
For homes near the ocean, where salt and moisture can wear down a roof rapidly, selecting the right roofing nails is paramount. Prioritizing stainless steel nails and accompanying them with a durable underlayment can ensure your asphalt shingle roof stands the test of time and tide.
