Perimeter fastening for tile roofing areas from either side of hips or ridges and edges of eaves and gable rakes includes which of the following?

• A. two tile courses but not less than 36 inches
• B. three tile courses but not less than 36 inches
• C. every other course
• D. two tile courses but not less than 24 inches

Answer: (B)

Perimeter fastening is all about creating a strong edge anchor to resist wind uplift on tile roofs. The areas on either side of hips or ridges and along the eaves and gable rakes are especially exposed, so you need a deliberate, continuous strip of secure tile along those edges. The requirement calls for three consecutive tile courses along the edge, with a minimum length of 36 inches. This ensures enough fasteners and load transfer area to hold the edge in high winds and keep tiles aligned. Fewer than three courses won’t provide sufficient edge anchorage, and pairing a short length with only two courses or fastening every other course would leave gaps and reduce resistance to uplift.
