Hey all, first post on this site I bought a home that was built in 79. The siding appears to be T1-11, but is at a 45 degree angle. It has wood rot and needs replaced. Fortunately,the area that is bad is not too big. My question is this, A. Might it not be T1-11? When I remove, can I reinstall T1-11 at an angle (45 degree)?
