- Clips: metal connectors that are attached to the roof truss and the wall plate. They are designed to transfer the uplift forces from the roof to the walls during high winds. Clips are typically made of galvanized steel or stainless steel and are available in various sizes, depending on the roof pitch and the spacing of the trusses. The primary advantage of clips is that they are relatively easy to install and are cost-effective.
- Single Wraps: Single wraps are metal straps that are wrapped around the truss and secured to the wall plate with nails or bolts. Single wraps are usually made of galvanized steel or stainless steel and are available in various sizes. They are designed to transfer the uplift forces from the roof to the walls during high winds. The primary advantage of single wraps is that they provide a more robust connection than clips, but they are more expensive and challenging to install.
- Double Wraps: Double wraps are metal straps that are wrapped around the truss twice and secured to the wall plate with nails or bolts. Double wraps are typically made of galvanized steel or stainless steel and are available in various sizes. They are designed to transfer the uplift forces from the roof to the walls during high winds. The primary advantage of double wraps is that they provide the most robust connection and are typically required for homes in high wind zones.
- Toenails: Toenails are nails that are angled at a 45-degree angle and are driven through the roof truss into the wall plate. Toenails are the least effective type of roof-to-wall connector and are typically only used in older homes. They do not provide adequate resistance to uplift forces during high winds and are not recommended for use in new construction. In regards to the wind mitigation form, clips or straps that do not meet the minimum qualifying requirements, are considered “toe-nails.”
