Choosing the Right Roofing Staples for Tar Paper: A Complete Guide

When installing tar paper as an underlayment in roofing projects, selecting the appropriate roofing staples is crucial for durability and effectiveness. Roofing staples play an essential role in securing tar paper firmly to the roof deck, preventing shifting or damage during subsequent shingle installation and weather exposure. This guide explores the types, sizes, materials, and best practices for using roofing staples with tar paper to help homeowners and contractors ensure a secure, long-lasting roof.

Aspect Recommended Roofing Staples for Tar Paper
Staple Gauge 16 to 18 Gauge
Leg Length 1/2 inch to 9/16 inch
Material Galvanized Steel or Stainless Steel for Corrosion Resistance
Head Type Flat or Crown Head for Secure Hold
Staple Gun Type Hand or Pneumatic Stapler Compatible

Why Roofing Staples Are Ideal for Securing Tar Paper

Roofing staples provide a quicker and more efficient method for fastening tar paper compared to nails, especially for large roofing projects. Their wide crown design ensures the tar paper is held firmly against the wood deck, minimizing wrinkling or lifting in windy conditions. Additionally, roofing staples reduce the risk of tearing the tar paper during installation due to their sharp, penetrating points and fine gauge.

Key Features to Consider When Choosing Roofing Staples for Tar Paper

Gauge (Thickness) and Durability

For roofing staples used on tar paper, 16 to 18 gauge staples are most commonly recommended. This gauge offers an optimal balance between strength and penetration ability. Staples that are too thick may damage the tar paper or wood, while too thin staples lack holding power and may bend during installation.

Leg Length

Staple leg length typically ranges from 1/2 inch to 9/16 inch for securing tar paper. The legs need to be long enough to penetrate the tar paper and embed securely into the roof decking while avoiding excessive penetration that could risk damage beneath the decking or cause uneven fastening.

Material and Corrosion Resistance

Since roofing projects face exposure to the elements, staples made from galvanized steel or stainless steel are preferred to prevent rust and corrosion. Corrosion-resistant staples ensure the tar paper remains securely fastened over time, maintaining roof integrity and avoiding costly repairs.

Head Type and Holding Strength

Flat or crown head staples provide a larger surface area to hold the tar paper without tearing. A wide crown staple helps distribute pressure evenly, reducing the chance of the material ripping during strong winds. Some staples have adhesive-coated heads for extra grip on rough surfaces.

Types of Roofing Staples Commonly Used for Tar Paper

  • Galvanized Steel Staples: The most popular choice, combining strength and rust resistance.
  • Stainless Steel Staples: Ideal for coastal or high-moisture environments where corrosion is a significant concern.
  • Coated Staples: Some roofing staples come with a weather-resistant coating for enhanced durability and holding power.

Tools for Installing Roofing Staples on Tar Paper

There are two common types of staple guns used to fasten tar paper:

  • Manual Staple Gun: Suitable for small to medium-sized projects. Requires moderate physical effort but offers control over staple placement.
  • Pneumatic Staple Gun: Powered by air compressors, these allow for rapid, consistent installation ideal for large roofing jobs and professional contractors.

Using the correct staple gun enhances productivity and ensures that each staple is driven properly for optimal holding strength.

Best Practices for Installing Tar Paper with Roofing Staples

  • Space staples evenly: Install staples approximately 6 to 8 inches apart along the edges and every 12 inches in the field of the tar paper.
  • Avoid overdriving staples: Staples should be flush with the tar paper surface to prevent tearing or puckering.
  • Overlap seams correctly: Overlap tar paper layers by at least 2 to 4 inches, fastening securely with staples along overlaps for a weatherproof barrier.
  • Check substrate condition: Ensure the roof deck is clean, dry, and free of debris before applying tar paper and staples for maximum adhesion and effectiveness.

Common Mistakes to Avoid When Using Roofing Staples for Tar Paper

  • Using staples that are too long or too short: Incorrect lengths can result in weak fastening or roof deck damage.
  • Using non-galvanized staples: This leads to rust buildup and premature failure.
  • Uneven staple spacing: May create weak points prone to tearing or blow-off.
  • Ignoring staple gun settings: Improper depth settings can cause over-penetration or insufficient holding.

Comparing Roofing Staples With Roofing Nails for Tar Paper

Feature Roofing Staples Roofing Nails
Installation Speed Faster due to staple guns Slower, typically requires hammering or nail guns
Holding Surface Wider crown holds material better Smaller head surface area
Material Damage Less likely to tear thin materials if proper gauge used May cause tearing or cracking if driven poorly
Corrosion Resistance Generally corrosion-resistant options available Varies; galvanized nails common

Overall, roofing staples are preferred for tar paper due to easier installation and better material securing ability.

Where to Buy Quality Roofing Staples Suitable for Tar Paper

  • Local Hardware Stores: Major chains like Home Depot, Lowe’s, or Menards carry roofing staples with recommended specifications.
  • Roofing Supply Centers: These specialize in professional-grade nails and staples with expert advice.
  • Online Retailers: Websites such as Amazon, Fastenal, or Grainger offer wide selections and bulk options for roofing staples.

Choosing reliable brands ensures staple durability and compatibility with staple guns used in tar paper installation.
