Hi folks,
My house is about 20 years old and is partially sided with T1-11. I’m replacing it with Hardiplank. The T1-11 paint is peeling and nasty (and the stuff is ugly anyway) but I’m wondering if I should install right over it? I live in a dry climate (Arizona) and the T1-11 doesn’t seem to be suffering from rot or mildew or other type of water damage. One small wall is done and I had to strip the siding off for visual inspection of possible water damage, so I re-sheathed with OSB and discovered there is housewrap under the current siding. I figure rather than have to dispose of a bunch of old siding and replace it with new sheathing, why not kill two birds with one cementious stone. Anybody see any problems here?
Thanks in advance for advance, warnings, etc.

Go for it, no problem. Figure out the window trim tho', they may be captured behind the T-111, funny, but I've seen it.

Thanks! Actually all the windows are going to be replaced, so off comes the ugly trim and I should be able to figure out the new trim details (I hope).Gatordoc
Do your windows and trim first, then side. And yes, you can side right over the T1-11.
If you've cut away T1-11 to remove your old windows, fill in around with strips of t1-11 or ply or OSB of appropriate thickness so that the siding/planks will go onto a flat wall surface. Consider your flashing over/around your windows and doors - or maybe that isn't done in AZ?

Thanks jimjimjim,Yup, we flash here as well. Doesn't rain often but is considered monsoon rain when it happens. Let me tell you about our swim-out basement...Gatordoc
The only thing I'd add is that if you want to do anything inside those walls in the next 30 years, now's the time.
If your house is properly wired and adequately insulated, then go ahead with the cement board over the t1-11. If it's not, well, I'd at least give some thought to pulling the plywood off.
