Cedarwood Shingles

Has anyone any idea of the cost of cedar-wood roof shingles . Most sites refer to the cost per square , but what is a square . Any idea how I calculate the amount required . I already have 9 bales they measure 6" thick by 26 " long by 20 " wide . I guessing I need another 20 to 25 bales !!!!

A square is 10' x 10', or 100 square feet, hence "square".

How large of an area are you covering?

 

Wow hank that was fast :-D I' m doing an area about 600 square feet . Any idea how far the bale will go ?

Notaclue. Each manu. bundles them differently, and it would also depend on your overlap.

 

Thanks anyway Hank , nothing for it but to open a bale and lay them out on the ground

If they are packaged anything like regular shingles, one bundle covers 1/3 of a square. So it would take 3 bundles to do a square. So that would be 18 bundles if my calculator is correct?
