When it comes to roof coverings, you have several choices, among them shingles, clay or concrete tiles, metal panels, and slate. But which of these roof coverings perform best during severe winds? The answer may surprise you. All of these types of coverings can perform well if they are attached properly. For shingles, hand nailing is best for accuracy and six nails per shingle are preferred, especially in high wind areas. It is also wise to apply a dab of roof cement under each tab. For clay or concrete tile installation in high wind or seismic areas, use nose, butt, or side clips. These clips are commonly referred to as wind clips or storm anchors. Two screws per tile give the highest wind uplift resistance and will help the tile resist shifting.
