What are Umbrella Roofing Nails?
Umbrella head roofing nails, also known as cap nails, feature a large, umbrella-like head designed to provide enhanced protection against water penetration. The inclusion of a rubber washer further fortifies the seal, making them ideal for roofing applications
1. Material:
High-quality umbrella roofing nails are predominantly crafted from galvanized steel. This material offers excellent corrosion resistance, crucial for withstanding outdoor elements.
2. Head Design:
The umbrella-shaped head is a distinctive feature, providing a broad surface area for effective sealing and preventing water ingress.
3. Rubber Washer:
The rubber washer, positioned beneath the head, acts as an additional barrier against moisture. It ensures a watertight seal, even in the harshest weather conditions.
4. Shank Type:
Umbrella roofing nails typically have a smooth shank. This design allows for straight forward insertion and minimizes wood splitting.
5. Size Range:
These nails are available in various sizes, ranging from 1 1/2 inches to 3 inches. The choice of size depends on the specific requirements of the roofing project.
Uses and Advantages
1. Roofing Installation:
Umbrella roofing nails are primarily used for attaching roofing materials such as asphalt shingles, underlayment, and felt paper to the roof deck.
2. Weather Resistance:
The rubber washer, coupled with the galvanized steel construction, provides an exceptional defense against moisture, making them suitable for climates with heavy rainfall or high humidity.
3. Reduced Maintenance:
The watertight seal created by the rubber washer minimizes the likelihood of leaks, reducing the need for costly and time-consuming repairs.
4. Longevity:
The galvanized steel construction ensures that these nails maintain their structural integrity over extended periods, even in harsh environmental conditions.
Conclusion
Investing in high-quality umbrella roofing nails with rubber washers is a fundamental step towards safeguarding the structural integrity of any roofing project. Their innovative design, featuring a rubber washer and galvanized steel construction, provides unparalleled protection against water infiltration.
