Can you offer some advice.
Building a front door overhang.
Drill holes through the lumber and into the wall every 6 inches along the length of the lumber.
Add support boards and then screw the entire truss structure on top of the corbels.
Fit a wall plug into each hole in the wall.
In fact it is that small bit of protection that ensures that you can stand outside your door having a last minute chat with your visitors without bothering about the elements.
Lift the remaining roof width lumber onto the wall 12 inches above the door frame and center lumber over the door so there is 1 foot of wood on each side of the frame.
Install the corbels flush with the top of the door trim and against the side door trim.
Use your template roof to measure and cut angled truss boards then screw them together and into the end caps.
Our house has no overhang or protection from the weather at the front door.
The thing that you should know about door overhang is that it is a tiny awning or cover that hangs over the door literally and protects you from sunlight rain or snow.
