Poor drainage, frost heaves, and time
This garage had numerous structural issues to be addressed: bowed walls, rotten bottom plates, a saggy ridge, and a concave roof deck. After we took care of those issues, we moved onto the rotten trim and siding. We patched in new siding, repaired the old sash windows, rebuilt the roof deck, installed standing seam panels on the roof, and installed new skirt boards, corner boards, frieze boards, soffit and fascia boards. And then we painted it.
