I have a question about rotting wood soffits. Our house was built in 1968 and is a mid-century modern custom home. It has about 3.5' overhangs on most of the house where the soffits are wood. We want to have vinyl soffits installed and I am curious how this would work. Would they just install the vinyl soffits OVER the wood? I am attaching a link to photos of our house (taken for landscaping purposes, but will suffice for this as well).
