I've recently discovered that the double back door to my sunroom has a water infiltration issue on either side of the door, resulting in some rot of the subfloor inside. The sunroom was constructed over an existing deck by a contractor, so I'm not sure of the root cause. This has been in place for about eight to ten years.
If I were to install a small overhang above the door, it may help to keep some of the water out. When it rains, a lot of water appears to be dripping off the gutter, even though it is not clogged (I've checked.) It has even worn off some of the stain on the top step (you can barely see this in the photo.) Since this has vinyl siding, I'm seeking suggestions on best securing a small overhang to protect it. Do I simply secure a pressure-treated board on top of the vinyl siding? Would this even help? Any and all suggestions are appreciated. Attaching a photo of the door for reference. Thx.
