How Much Overhang On Roof Trusses

This can make extensive roof overhangs more trouble than they are worth in all but the harshest climates.

How much overhang on roof trusses.

How do you secure a truss. If the overhang is more than around 2 6 it will require a 2 6 top cord for the tail section to handle that amount. If the overhang exceeds 2 5 feet we will need to use a larger top chord for the overhang typically a 2 6 top chord for the truss. Two feet is the general maximum length for a typical roof overhang.

We can also build a cantilever for the overhang which is where the bottom chord of the truss continues beyond the wall. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports. This will protect a roof from most types of damage. That said overhangs can extend as far as 2 without the need for external supports.

A standard overhang is 16 24 inches but the overhang can be any length you wish. Overhang this is the extra part that extends beyond the exterior wall of the home. This length can easily be changed to fit the need of the truss. Pitch is a measurement of roof rise and width.

Depending on the complexity of your free computational tool it may require you to enter details about rafter spacing usually 16 on center bridge type height and board size. However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes. Measuring trusses depends on how much overhang you want length and pitch of the roof.
