Nails vs Staples: A Quick Comparison
What Are Nails?
Nails, typically made of galvanized steel, copper, or aluminum, are the traditional fasteners used in roofing. They come in various lengths and diameters, with the most common roofing nails being around 1 to 1.5 inches long. Nails are driven into the shingles and the roof deck, providing a secure hold that resists pull-out forces.
What Are Staples?
Staples, on the other hand, are U-shaped fasteners made of metal wire. They are usually applied using a staple gun, which drives the staples through the shingles and into the roof deck. Staples are available in different sizes, but roofing staples generally have a crown width of about 1 inch and legs that are 3/4 to 1 inch long.
Key Differences
The primary differences between nails and staples lie in their structure and installation methods. Nails penetrate the shingles and the roof deck, offering a secure hold that resists pull-out. Staples, however, use two legs to anchor the shingles, which can provide a quicker installation process but may not be as durable. Additionally, nails are generally more expensive than staples, affecting the overall cost of the roofing project.
Advantages of Using Nails for Asphalt Shingles
Durability and Strength
Nails provide superior durability and strength when used for asphalt shingles. The single shank of the nail penetrates deeply into the roof deck, offering a secure hold that withstands significant stress. This resistance to pull-out is crucial for maintaining the integrity of the roof over time, especially in areas prone to high winds or heavy snow loads.
Weather Resistance
Nails offer better weather resistance compared to staples. They are less likely to loosen or back out during severe weather conditions, such as storms or high winds. The deeper penetration of nails ensures that the shingles remain securely attached to the roof deck, reducing the risk of leaks and water damage. This makes nails a preferred choice in regions with extreme weather variations.
