I need to replace the white board above this garage door. The 2x12 is
rotted out pretty bad. It will just fall out when poked with a
screwdriver or putty knife, so I'm going to replace with a new, treated
2x12. (Client wants cheapest option.)

..

Any ideas?

To start I would tack the new 2x12 (or 1x12 if it turns out to be that)
up on the side jambs even with the bottom edge of the existing arch
board, or level, which ever seems better based on the field conditions.
Then I'd scribe the curve onto the new board by following the existing
curve. This could be done with a large pencil compass. Alternatively a
board that is as long as the distance from the bottom of the curved board
to the maximum height of the curve and a pencil could be substituted. In
either case make sure the scriber is plumb as you move across the length
of the board. Any roughness in the scribed line can be smoothed out
during and after cutting the board... a slight undercut would help with
the fitting.

Another consideration might be to get some 1x12 pvc trim (or glue up
narrower boards). If needed shim it out with with the scrapes from
cutting the curve. It would hold up better than wood.


Great advice. Thanks.
PVC is a fortune around here, I don't see the client going for it.

I took a look at the photo again after I posted about the drip cap on the
curve... I think you also need some window/door cap flashing between the
curved board and the top board of the door frame.

You could probably modify this stuff for the curve too if you don't have a
brake to bend up the flashing I suggested in my prior note. For example,
trim the top leg down to about 1/4" and put some relief cuts in it. Then
turn it into a hem with a hand seamer. For example:

After you have the curve bent into it apply some silicone chalk at the
relief cuts.
