Where three roof slopes come together, leaks happen. Our roof was mostly replaced in ~2014, thanks to a hard working friend/former resident of the Little Yellow House. However, there was a design flaw (not the friend’s doing), that left the roof vulnerable to leaks. That flaw has been partially alleviated after sawing out a chunk of roof (significant pucker factor), removing a softball sized wad of old burlap, adding some plywood, and emptying a can of spray foam. We’re planning to hire a professional to do the final roofing. A side benefit is a substantial increase in headroom at the top of the stairs. In essence, we switched which slope was limiting head space from the 3/12 running perpendicular to the stairs to the 12/12 slope running in line with the stairs. Overall, we are very pleased with the reduced risk of future leaks and extra 12” of minimum clearance for taller folk.
