On the main cabin we have had woodpecker problems over the years. Apparently the woodpeckers like to nest up high with a vantage point of the meadow. The gable end of the main cabin was perfect and they had made a mess of the tongue-and-groove cedar siding. We had patched with metal, but finally had to take drastic measures. My father-in-law had a guy apply galvanized steel sheet to the walls and then apply cedar shakes over that. This has mostly worked. Occasionally a wood pecker will attack, but after 1/2 inch of progress will give up. So on the pavilion, we’re taking the galvanized-plus-shakes approach from the get go.
