What is the minimum shank diameter for fasteners used with asphalt shingles?

10 gage
12 gage
14 gage
16 gage

The correct answer is: 12 gage

The minimum shank diameter for fasteners used with asphalt shingles is typically set at 12 gage. Fasteners of this size ensure adequate holding power and resistance against weather conditions, such as wind uplift, which is a crucial consideration for shingle roofs. A 12 gage fastener provides a balance between strength and the ease of handling and installation. Utilizing fasteners with smaller shank diameters may compromise their effectiveness in securing the shingles properly against the elements. Conversely, larger shank diameters, while potentially stronger, could also lead to issues such as splitting the roofing material or not complying with manufacturer guidelines. Therefore, the choice of a 12 gage fastener aligns with industry standards and best practices for roofing installations involving asphalt shingles.
