I have a composition roof. The exterior of my house is mostly brick, but has some wood siding on a vertical part of the house which runs between a higher section of the roof and a lower section of the roof. This wood siding looks to be in good condition overall, except for the bottom of each siding board where it meets the lower part of the roof. This joint where the wood siding and lower roof section meets is slanted, so undoubtedly it gets more water contact than the higher siding as water runs down the lower roof section.
I think it looks rather raggedy, and of course I'm concerned about future leaks and pest infestations although I have yet to notice either. Is there a good way to fix this lower edge without replacing the entire section of siding?
