I've got the typical tract house out here in Central TX. Built in the '80s with T-111 siding. The bottom on T-111 tends to rot where it contacts the bottom moisture. I bought the house 6 years ago with some pretty bad spots so I cut the offending T-111 off and replaced it. The rest looks fine. I wonder how many people replace all the siding when only about 6" is actually bad?
That's not the question. I want to re-do the siding on at least one side of my house to make it better sound and weather insulated.
The question is: What about weather resistant sheet insulation and new T-111 siding and going over the existing siding (assuming I weather sealed it of course) and putting on new trim?
Anyone ever done this? Why take the old siding/insulation out/ Why not just add to what is there and just putting on another layer?
