Rotten white pine log siding removed and replaced with white cedar log siding with vertical corners instead of the log ends. Stained with 2 Coats Perma chink ultra 2 stain in Bronze with lifeline advanced clear. Failed caulk allowing water to get behind the log siding cause the majority of the Damage. The new white cedar siding has a tongue and groove on all sides that help prevent this problem and excessive caulking. Large overhangs would also have helped.
