Roof details control the installation
Pitch, shingle layout, nearby valleys, rafters, and roof age all affect placement. The selected unit should match the roof and the homeowner's daylight or ventilation goal.
Avoiding future leak problems
Flashing should be integrated with the roofing courses rather than covered by surface sealant. The completed work should be photographed and reviewed before interior finishes are closed.
- Confirm unit and placement
- Coordinate roof and interior work
