Safety Considerations
For safety, always wear fall-arresting equipment when working on a roof.
Start at the end with the last over-lapping cap shingle.
Remove the shingle cap.
Cut the Ventilation Opening
The next step is to cut the wood decking back along the ridge.
Secure the decking below each chalk line with new 8d nails driven into the roof rafters or trusses below.
Using the circular saw, cut the decking along the chalk lines.
Remove the waste strips of decking from along the ridge.
Attach the other side of the vent to the opposite side of the ridge to fully secure the vent.
Install asphalt shingle caps over the vent, using the nails recommended by the manufacturer.
Position the aluminum ridge vent along the reference line.
Add any connectors and end caps that came with your ridge vent system to ensure the vent is watertight.
This project requires work on a tallladderand working atop the roof while using hand and power tools.
Be aware that a ridge vent is only one part of properlyventilating your attic spaceand roof.
