Among various measurements, 7/8-inch roofing nails are commonly considered for specific roof types and materials. But are they suitable for your application? Let’s break down the factors to help you make an informed decision.Understanding 7/8 Roofing Nails 7/8-inch roofing nails are short compared to standard options, which often range from 1 to 2 inches. These nails typically feature a wide, flat head and a smooth or ringed shank, offering good grip for lightweight roofing materials. Their shorter length makes them ideal for securing thinner roofing materials, such as asphalt shingles, without penetrating too deeply into the underlying sheathing.When to Use 7/8-Inch Roofing Nails These nails are best suited for situations where you need just enough hold without risking damage to the structure beneath. Examples include:Fastening thinner asphalt or fiberglass shinglesSecuring roof felt or underlaymentProjects with thin sheathing or when working atop existing layersHowever, for heavier roofing materials (like architectural shingles or tiles) or where stricter local codes apply, longer nails are often required.Material and Corrosion Resistance Always opt for galvanized or stainless steel nails for outdoor use. Galvanized nails resist rust and corrosion, extending the lifespan of both the fasteners and your roof.Building Codes and Manufacturer Recommendations Check your local building codes and the roofing manufacturer’s requirements. Many codes specify a minimum nail length (commonly at least 1 inch for shingles), number of nails per shingle, and type of nail to ensure wind and weather resistance.As a designer, I find that the success of any project is as much about the details as it is about the broad vision. Even the right size of a nail can impact the quality and longevity of your roofing system—quite similar to how a thoughtful home designer carefully chooses every element in your living space to maximize both function and aesthetics.Tips 1:Consider conducting a test on a sample piece to ensure the 7/8-inch nail offers sufficient hold for your chosen material.
