SlateTec Installation Instructions

Tools (Recommended)

  • Slate Cutter
  • Slate Hammer
  • Drill + 1/8” Bits For Slate (if needed)
  • Knife Or Scissors For Interlayment
  • Caulking Gun

 

A 1/4” or 3/8” riser strip can be used on eaves for first course, install drip edge over riser and first course of interlayment over drip edge. Rake Edge: cut interlayment 3/4” from outside edge and add one nail just above slate for added wind protection. (See diagram #1)

After a watertight base roof including all metal flashings, and all underlayments are complete, the roof is ready for SlateTec.

Standard slate length is 12” in random widths, with a required 4” over lap. Interlayment is 18” wide rolls. Install interlayment first over drip edge, then install slate in successive courses with a 4” over lap, fastened with copper nails. 14” slate pieces can be used as a drop down for a staggered appearance. Hip and Ridge also requires a 4” over lap over a 12” strip of interlayment. (3 nail holes are recommended on each ridge piece).
