How Much Overhang On Roof Trusses

However the suggested width of an overhang is between 12 and 18 for eaves and no more than 8 for rakes.

How much overhang on roof trusses.

This length can easily be changed to fit the need of the truss. 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. 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. This can make extensive roof overhangs more trouble than they are worth in all but the harshest climates.

Measuring trusses depends on how much overhang you want length and pitch of the roof. Overhang this is the extra part that extends beyond the exterior wall of the home. 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. A standard overhang is 16 24 inches but the overhang can be any length you wish.

How do you secure a truss. 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. A 4 12 pitch would rise four feet for every twelve feet of roof width.

The average overhang for trusses used for housing or related buildings with a finished soffit is between 1 4 to 2. Two feet is the general maximum length for a typical roof overhang. Pitch is a measurement of roof rise and width.
