Hi, I bought a property with an old cabin on it and the structure is a real hack job. The specific problem (among many others!) that I'm dealing with right now is that the framing was built directly on a patio deck and they didn't run the siding low enough so when it rains the water runs down the siding and on the side of the decking/subfloor which in turn lets moisture inside and under the stick framing and rots and causes mold to form inside the walls at the bottom. So my question is, how should I extend the siding just a few inches down so that the rain water would run past the decking into the ground? I thought about using flashing tape as a semi-temporary solution. Any thoughts? See the photo of the siding/decking below. Thanks!
