CLOSE SHEATHING THE BEST.
Reading edition
While a rain-proof roof can be made with our shingles, our system, as well as all metal or slate roofing should not be put upon open sheathing. If walked upon the metal will not support the weight, and bends out of shape, and the roof is blamed. In high latitudes where we have driving storms of fine snow or “blizzards,” we specify close sheathing covered by paper (using same rules as for laying slate). We will then guarantee a perfect roof.
