Do hurricane ties go on both sides?

Do hurricane ties go on both sides?

These ties are designed to attach to connect the wall’s top plate with the truss rafter. For maximum lift resistance, they can be installed on both sides of the rafter or joist.

Where do you put a rafter tie?

Where rafters are oriented perpendicular to the ceiling joists, rafter ties should be installed just above the ceiling joists. The ties usually rest on the joists. When rafters are installed on 24-inch centers, rafter ties are typically installed at every other rafter.

Can you use screws with hurricane ties?

Why not use screws? However, the risk if construction screws are used in steel connectors such as hurricane tie-downs is that such screws might break under load across the screw diameter even though their screw design resists pulling out of the wood.

How do rafter ties work?

Rafter ties are installed between opposing rafters, and they should be installed as close as possible to the top plate. Rafter ties resist the outward thrust that rafters exert on the exterior walls. They help keep walls from spreading due to the weight of the roof. When the walls spread, the ridge board might sag.

Are hurricane ties required on rafters?

Building codes in hurricane areas, and areas where high winds can be expected, require the installation of metal ties, or straps as follows: “Roof assemblies shall have rafter and truss ties to the wall below. All new buildings are required to have hurricane ties installed.

Should I use screws or nails for hurricane ties?

Fasteners with Hurricane Ties While many hurricane ties have been evaluated with 8d x 1½” nails for compatibility with nominal 2x roof framing, some require the use of a longer, 8d common (2½” long) nail and others require a larger-diameter 10d nail.

Can I use screws on hurricane ties?

Does every rafter need a rafter tie?

Rafter ties are always required unless the roof has a structural (self-supporting) ridge, or is built using engineered trusses. A lack of rafter ties is a serious structural issue in a conventionally framed roof. In most homes, the ceiling joists also serve as the rafter ties. The ties usually rest on the joists.
