I am currently installing a new roof with your tiles (slate) it is a dual pitch 8 on 12 and 16 on 12. My question is how many nails are required per tile? Are more required on the 16 on 12?
Unless you are in a designated high wind region, the tiles installed above 12:12 would all have to be fastened and those below 12:12 would require alternate tiles or all tile on alternate courses to be fastened. This would be in addition to all tiles within three feet of the roof perimeters. It should also be noted that Canada has slightly different fastening requirements and you should check with your local building official to see if there are special considerations. Last November we had your light weight cement tile (in the shake profile) installed on our roof. Looks great Unfortunately, with the spring melt, ice slid off the roof and broke many of the lower tiles. Can you send us information as to how far the last row of tiles is supposed to extend from the edge of the roof, unsupported by plywood. Possibly the contractor left too much overhang, there is several inches.
