Screw in louver with construction screws.
Attach small gable to wood siding.
If you have beveled horizontal siding then use an inverted piece of siding as shown in the illustration here to create a plumb flat surface for attaching the ledger.
We used 2 1 2 construction screws one each at the top and bottom to attach the gable decorations to our home.
Grab your tape measure and find the center and mark accordingly.
This is due to the fibrous siding material s weakening over time as stress is placed on the material from the awning.
Another way would be to pull off some siding at the top of the wall on the gable end right where you are going to be starting the addition.
Once you can reach the heel carefully measure the height of it vertically at the outside corner of the wall to within 1 8 inch.
If the wood siding is beveled or lapped you will need vertical furring strips 16 inches apart covered with rigid foam board to provide a flat surface.
They were the perfect size to reach all the way through the louver and into our siding.
Wood product siding can be manufactured from medium density fiberboard high density fiberboard osb solid wood or plywood.
