High Nailing: Understanding Its Impact on Roof Integrity

Introduction to High Nailing and Its Consequences

High nailing, a common issue encountered in roofing installations, significantly affects the durability and performance of roofing systems. This improper practice compromises the roof’s ability to withstand environmental challenges, leading to potential damage and the need for premature repairs. Recognizing the importance of correct nailing techniques is essential for maintaining the structural integrity of your roof.

The Correct Nailing Technique: Ensuring Roof Longevity

The correct nailing technique is pivotal in roofing installation, ensuring each shingle is securely attached and capable of resisting wind uplift and water penetration. Shingles should be fastened at a specific area designated by the manufacturer, usually marked as a nail strip. This strip is engineered to provide optimal hold and distribute the force of the nail across a wider area of the shingle, reducing the risk of tear-off and leakage.

The Three-Point Attachment Method

A well-executed roofing installation follows the three-point attachment method, which involves:

• Securing the shingle at its lowest point where it overlaps the shingle below, creating a continuous barrier against water.
• Fastening the shingle in the designated nail strip area to anchor it directly to the roof deck.
• Ensuring that as subsequent shingles are installed, the nails also penetrate the top of the shingle below, reinforcing the attachment to the roofing system.

This method guarantees triple-layer protection for each shingle, significantly enhancing the roof’s resilience against environmental factors.

The Risks of High Nailing

High nailing occurs when the fasteners are placed above the manufacturer’s recommended nail strip. This misplacement undermines the shingle’s ability to form a secure bond with the roof deck, making the roof susceptible to:

• Wind Damage: Shingles are more likely to be lifted or blown off during high winds, exposing the roof deck to the elements.
• Water Infiltration: Improperly nailed shingles can allow water to seep beneath, leading to leaks, mold, and rot in the underlying structures.
• Voided Warranties: Many manufacturers void warranties on shingles that are not installed according to their guidelines, including proper nailing practices.
