Installation Guide for Tower™ Roofing

8. Starter Course

When installing the starter course, be sure to allow a 1/2” (1.25 cm) overhang from the edges of the roof (this should bring the starter shingles to the edge of the drip edge). To ensure a secure fit, nail the starter shingle down with two 1½” (3.8 cm) fasteners approximately 3-5” (7.5 - 12.5 cm) from the edge of the roof. Align the shingle with a minimum 3/16” (4.75 mm) space between shingles (the spacers on the shingles may result in a larger space for the Tower™ Slate). The starter row will consist of full shingles, so there will be a ‘double layer’ at the eaves.

Important Reminder:
Don’t forget that the first row of exposed shingles sits directly on top of the starter strip. When installing the first row, make sure they are shifted exactly half a shingle sideways so to avoid shingle side edges aligning with the starter shingle side edges.
