For homeowners and professionals diving into the world of roofing, understanding the different components is crucial. One such component, often overlooked but of significant importance, is the wood nailer. In the context of asphalt roofing, let’s delve into what a wood nailer is and why it matters.
1. Definition: What is a Wood Nailer?
A wood nailer, often just referred to as a "nailer," is a strip of wood, usually made of treated lumber, which is used to create an even surface or edge for roofing attachments. It offers a solid backing or anchor where roofing materials, such as asphalt shingles, can be nailed.
2. Uses in Asphalt Roofing:
a. Edge Detail:
Wood nailers provide a firm edge, especially in low-slope or flat roofing systems. They support and define the roof’s perimeter, ensuring proper attachment of flashing, gutters, or other edge metals.
b. Equipment Supports:
For roofs housing equipment like HVAC units, wood nailers offer an even base to affix supports or curbs.
c. Roof Projections:
Skylights, vents, or any other projections on an asphalt roof often require wood nailers to provide a flush surface for watertight installations.
3. Benefits:
a. Nail Holding:
Wood nailers provide an appropriate depth and a solid medium for nails, ensuring the roofing materials remain securely anchored.
b. Roof Integrity:
They help in achieving a leveled and smooth roofing surface, which is critical for the longevity and performance of asphalt roofs.
c. Versatility:
Wood nailers can be cut and shaped to fit various roof details, making them adaptable to complex roofing designs.
4. Best Practices:
a. Treated Lumber:
Opt for pressure-treated lumber when choosing wood nailers. It resists rot and offers a longer lifespan.
b. Secure Attachment:
Nail or screw the nailer firmly to the roof deck to prevent any movement or shifting over time.
c. Check Thickness:
The thickness of the wood nailer should match the insulation or roofing system’s height to ensure a level surface.
Conclusion:
The asphalt roof wood nailer, while a seemingly simple component, plays a pivotal role in the structural integrity and performance of the roofing system. Whether you’re installing a new roof or making modifications to an existing one, understanding the function and importance of wood nailers is essential for a successful roofing project.
