For the arrangement of the gable end overhang for the standard roof you lengthen the ridge beam beyond the facade for previously verified length using cut rafters.
Gable end roof overhang framing.
When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in.
Ladder trusses are made up using four noggins bridging at each corner to support a rafter outside the building.
Avoid gable ends that are over 8 in.
The picture above shows the plan view of a gable roof.
After the end points of the plates are located the length is found using a base 1 triangle for a 6 in 12 pitch where the hypotenuse is 1 118 times the length of the base.
Gable end overhangs constructed using the ladder detail.
If the overhang is less than about 12 the overhang may not be at great risk but a poor roof sheathing attachment could still pose a risk.
For slanted roof sheds overhangs add character and facilitate proper drainage.
This will be most.
That rafter outside forms the overhang for the barge boards to fix to and so the soffit boards and ventilation are continuous all the way around the structure.
Wide especially when the eave overhang is less than 12 in.
Gable end overhangs need to be well connected to the wall below.
Then load bearing roof beams fixed to the trusses are extended in the same way.
Uplift of roof decking at the overhang the other common wind related failure at gable ends is uplift of the roof decking at the overhang.
Thick and the overhang from the side wall set between 12 in.
There are several methods of making connections.
This can be from two causes.
To 18 in depending on the style of the building.
After the gable is framed lookouts extend from the first rafter inside the gable wall out over the plates to support the overhanging barge rafter.
A rake on the gable end of the roof can be created with the construction of additional roof framing.
If the gable end overhang uses the ladder detail method of construction and the length of the overhang is greater than 8 inches to 12 inches you may be able to strengthen the connection of the overhang by installing from the attic inch diameter lag screws that are long enough to go through the gable truss or rafter through the wall sheathing and 1 1 2 inches into the inside framing member of the ladder framing.
Inadequate nailing of the sheathing to supporting framing or inadequate connections of the framing at the rake edge that supports the roof.
