metal over wood shakes

g man

I would like to know if i can go right over the top of old wood shakes, it's on an old farm shed .i think it would faster and less mess thanks for any input

You can do anything you want if its your building, but it is not best practice.

It is done a lot over cut shingles, but split shakes are mush thicker ond less uniform, so I do not think I would do it if it were mine.

no matter what its always a better job to strip the old roof.

If the shakes are laying flat, and if you use long woodgrip screws, it can be done, but be aware that if you walk on the steel, even 26 ga., you can dent it from the back side and it will be visable from the ground. As the above posts advise, it is always better to strip a roof, but we have installed many over shakes with no problems.
