Step 1

Use on a minimum 3/8" (10 mm) plywood or OSB decking.

Step 2

Cut a 2" (51 mm) slot along the ridge, 1" (25.4 mm) on each side. Leave uncut (closed) sheathing area of 6" (152 mm) at each end of the ridge. Cut through sheathing only, avoiding roof trusses. (In houses with a ridge board, cut 3 " (89 mm) slot, one on each side.

Step 3

Where short ridges (dormers, ridge intersections) are used, mark and cut the slot and make sure that the end of the opening stops at least 12” (305 mm) from the ridge intersection.

Step 4

Uncoil Python Weather-Tite Rolled Ridge Vent along the entire length of the ridge, covering uncut 6" (152mm) sheathing area on both ends. Shorter lengths can be joined by caulking and butting the end.

Step 5

Install cap shingles directly over Python Weather-Tite Rolled Ridge Vent. Use included 1 ¾” (44.4mm) coil nails. Python Weather-Tite Rolled Ridge Vent has a ¾” (19.1mm) nominal thickness. Be sure not to crush or compress the vent during installation.
