My house has T-111 type plywood panel siding on it. When it was installed long before I bought the house, on an addition it was installed much too close to the ground. Unsurprisingly, in these areas, the siding has rotted and is falling apart.
Because the foundation of the addition is not nearly as high as the original house, the only way to fix the problem is to regrade or find another answer. For various reasons, regrading is not possible. So I want to cut off the bottom 10" or so of the siding and replace it with something more resilient like pressure treated lumber or cedar. The idea is that either will be more resistant to rot and insects, and further can be easily replaced in the future if it does succumb to the elements.
This raises two issues: 1) I'm having trouble finding z-flashing that accommodate anything thicker than 3/4" combined with 2) which is that that I'm having trouble finding pressure treated or cedar that is thinner than 1".
Ideally I'd have this board be the same thickness as the siding (3/8" or 5/8" probably), but I don't think I'll find that. Any ideas where to find 1" z-flashing?
Also, any suggestions for how to affix the z-flashing under the existing siding edge given that I'm installing this 'backwards'? Usually you'd start from the bottom and go up, so the flashing install is simple.
Will pressure treated accept a solid-color stain well enough to blend with the rest of the siding?
Comments on the whole plan or suggestions for alternatives are welcome.
thanks
