Easy Install
1. Using a chalk line, mark 1" on both sides of the ridge
(1" beyond ridge pole) as a guide for cutting a slot in the
decking.
2. Cut a slot in the roof ridge using a circular saw with
the blade set at a depth to cut through the roof decking
only - avoid cutting trusses and rafters.
3. Center the Python™ 3-IN-1 FlexFit™ Ridge Vent
over the slot that has been cut in the ridge, ensuring
that the RIDGE VENT support pegs sit flat on the roof.
To ensure proper alignment along the ridge, run a chalk
line down both sides of the ridge.
4. Using roofing nails provided, install the vent starting
from the outer edge moving inward. Properly secure by
using the 12" nail holes.
5. As you install more pieces of the RIDGE VENT,
ensure that each piece is joined together using the
male/female connectors.
6. Cut the final piece to a length long enough so that
it is flush with the edge of the roof. Ensure that the
self-closed end cap is facing out to prevent weather
infiltration. (Interlocking feature will not be used on the
final piece.)
7. Install the cap shingles using the nails provided in
the “shingle nail line” area for cap shingle installation as
indicated on the Python™ 3-IN-1 FlexFit™ Ridge Vent.
