ventilation to provide attic ventilation for a building. The vent system

- Leader Pipe:
a conduit for carrying water from a gutter, scupper, drop outlet or other

- Rake: the
sloped perimeter edge of a roof that runs from the eaves to the ridge. The
rake is usually perpendicular to the eaves and ridge.
- Ridge: the

internal intersection of two sloping roof planes that runs from the eaves to
the ridge. This intersection collects the most water run-off.
