What should be taken into account when toenailing trusses to the top plate of an outside wall?

When toenailing trusses to the top plate of an outside wall, it is crucial to consider resistance to wind uplift and thrust. This consideration is essential because trusses must be securely fastened to withstand forces that can occur during severe weather events, particularly high winds. Proper toenailing ensures that the trusses remain attached to the wall and do not lift off or shift under lateral loads.

This aspect emphasizes the structural integrity of the building. If the trusses are not adequately secured, they might fail to resist wind pressures, leading to potential roof failure or damage to the overall structure. Ensuring that the connection between the trusses and top plate is robust helps maintain stability and safety for the building.

Elements like thermal expansion, the weight of the trusses, and the type of nails used may also have relevance in construction, but the immediate priority during toenailing is ensuring that the fasteners can handle the resultant structural stresses from wind uplift and thrust.
