Remove the Fascia and Shingle Molding

Inspect and Replace the Rafter
If the exposed rafter behind the fascia and soffit is rotten, you’ll want to use a reciprocating saw to cut it free. Measure the missing piece of the rafter, cut a piece of a 2x4 that is the same size, and then screw it into place using a drill and galvanized steel screws to restore the rafter’s shape.
Replace the Soffit
Attach the soffit to the underside of the rafter, screwing it into the eave with the drill and several galvanized screws. Prefabricated soffits that have vents already installed in them have specific holes that you should drill through to ensure that you do not damage the rest of the soffit.

1. Determine the type and extent of the deterioration
The first and most obvious step is to look for rotten wood. Structural movement of the building may shift the cornice woodwork, opening up joints. This breaks the paint film, letting water soak into the end-grain causing checks, splits, and decay.
2. Plan the repairs
There are four basic types of repair techniques: wood Dutchman (a patch), lap-joint splice, wood-epoxy repair, and complete replacement.
3. Design and lay out the joint
Now that I know the conditions of the board in detail, I can design an effective joint. Here, I’ll use a 3″-long half-lap joint. I lay out the joint with a pencil, combination square and marking gauge (as in Step 2). I mark the shoulder of the lap 3″ back from the end of the board, using the square to make it 90 degrees to the edge of the board.
4. Cut and shape the joint
Next, I cut the shoulder. The depth of this cut extends only halfway through the board. I like to use a Fein multi-tool fitted with a saw blade, which goes a bit slow, but gives me more control for these tricky cuts. Working with a mallet and sharp chisel, I split away the waste [D] and pare down the surface of the cheek until it is nice and flat.
5. Create the replacement part
In the shop, I make the replacement part using the old board end as a pattern. The original soffits are made of heartwood Eastern white pine, so I select a board of the same.
6. Assemble the repair
Back up on the scaffold, I check the part in place, trim it to fit, and drill shank holes in the new part for screws to hold the joint together. Then I glue it into place with an epoxy adhesive.
7. Sand and finish
A light sanding completes the wood lap-joint splice repair, and it’s ready to be painted.
