I have a flat roof section and it has 4 layers of 1x6 fascia wood, numbered on the pictures as 1, 2, 3, 4 from top to bottom respectively.
The top fascia is mostly hidden by the drip edge of the roof.
Due to the direction the rain hits and the intersection wood structure, the fascia number 3 and 4 have rotted, it has rotted so badly it feels spongy if I apply pressure with my fingers.
However, I am not sure how best to remove this piece of fascia. The way it is nailed, I can't remove fascia 3 without removing fascia 2, and can't remove fascia 2 unless I remove fascia 1, and can't remove fascia 1 unless I completely pry out the drip edge of the roof.
Anyone has any creative way to make the repair without removing everything?
Can I use a circular saw sideways to cut fascia 3 flushed with the bottom of fascia 2 and go from there? Although I feel a bit nervous using a circular saw hang down from the roof holding it sideways, not to mention probably the saw will have some bulky parts that get in the way so flush cut is not possible.
Thanks in advance for any comments.
