How to replace wood siding & eaves

Updated February 21, 2017

When the wood of the eaves on your home's siding begin to rot, you can simply repair the damaged areas. If dry rot is set in and widespread, however, you will need to replace the eaves entirely. Don't worry, though, because the procedure for replacing the siding, eaves or both is simple. You can perform the replacement yourself as long as you have some time set aside and the appropriate materials. You can find the replacement siding, fascia and soffit wood boards at any home improvement store.

Tear down the old siding using a pry bar to release the siding from the side of the house.

Measure the new siding to the correct lengths by holding them up against the old siding you removed.

Treat both the front, back and the cut ends of the siding with primer to keep the wood from taking on water and rotting.

Paint or stain the siding to whatever finish you want and let it dry completely.

Start at the bottom of the house and nail the first piece of siding to the house.

Place a piece of metal flashing under the end of the first piece of siding before you place the next piece on that row. Nail the flashing in place.

Continue to cover the house in upward rows, maintaining a uniform overlap. If, for example, you overlap the first row of siding by 4 inches, each row that follows should also overlap by 4 inches

Place flashing behind each seam when running the siding to keep water out from behind the siding.

Remove the old fascia and soffit from the roof with a pry bar. These are the vertical and horizontal pieces of wood that comprise the eaves on the roof.

Use a nail remover to get any stray nails out of the roof.

Measure the new fascia and soffit boards by placing the old fascia and soffit on top of them and tracing them with a pencil.

Cut out the boards with a table saw and arrange them on the ground below where they will be attached.

Line the fascia up on the rafters of the house. This is the end of the roof hanging down over the wall of the house and the block of wood attached to the house below the roof edge.

Nail the fascia, the vertical boards, into the rafters of the roof with galvanised nails and a hammer.

Tack galvanised nails every several inches into the new soffit boards to make attaching them easier. Tack the nails by banging them in until they just breach the surface of the board, so you won't have to hold the nails steady while upside down.

Hold the soffit board to the underside of the rafters and finish driving the nails through the soffit and into the rafters.


Paint the back of the siding first and place it on a drying rack to paint the front for a clean finish on the front.


Use high quality, well-seasoned wood siding to prevent rotting.
