Planning a shed and wanted some input. I want to use T-111 siding as the exterior wall (we are in Southern CA). My question is about the bottom edge. Leaving the bottom edge raw (stained) might not shed the water when it rains. My worry is rot can start there. Is there a metal drip edge I can apply along the bottom edge of the T-111 to divert the runoff and prevent it from soaking into the bottom of the siding? Or, should I use a trim board along the bottom? I could run a 45 degree cut along the top of the trim then caulk the you-know-what out of the upper edge. Thoughts? How do you handle this is bad weather locations?
