Frequently Asked Questions (FAQs)
1. What are cap nails used for?
Cap nails are commonly used to attach roofing felt, house wrap, tar paper, and insulation foam board. They have a steel shank and a large polyethylene cap that helps prevent leaks and provides secure attachment.
2. What are cap nails used for roofing?
Cap nails, especially square and round ones, are primarily used for roof underlayment rather than shingles. The larger caps on these nails provide strong holding power, allowing for fewer nails to be used while keeping the underlayment material securely in place.
3. Do I need plastic cap roofing nails?
Plastic cap roofing nails, such as Grip-Rite® Plastic Cap Nails, are a recommended choice when securing house-wrap, rigid insulation, and felt. The round plastic cap adds strength and provides enhanced holding power for these applications.
4. Are cap nails waterproof?
Cap nails are not considered completely waterproof. While they are typically used with water-resistant synthetic roofing underlayment, they do not provide a sealed barrier around the fasteners. Therefore, they are considered water-resistant rather than truly waterproof.
5. Do you have to use cap nails for underlayment?
When it comes to underlayment, especially if it will be exposed for a while or on high-traffic roofs, it is recommended to use cap nails, crown cap staples, or roofing nails with 3/8” heads. These options provide better holding power and reduce the risk of tearing.
6. How long should cap nails be?
The length of cap nails depends on the specific roofing application. In general, for securing high definition ridge caps and a single layer of shingles, approximately two-inch nails are recommended. The nails should penetrate through or into the roof sheathing according to code requirements.
7. Do plastic cap nails leak?
Users of cap staple and cap nail systems do not experience water leakage through the underlayment or housewrap due to fastener holes. The cap nails allow the underlayment and housewrap to perform as designed without compromising their effectiveness.
