Roof Slot - Hip
2. Hip Vent:
A. SEE DIAGRAM 5 & 6.
Lay out the location of the slots to be cut, ensure that sufcient RidgeHawk is used to meet NFA requirements.
• A 3/4" inch slot will be cut on both sides of the hip rafter along the hip line.
• A continuous slot is not recommended, start the slots 6 inch from where the hip meets the ridge. [Diagram 5]
• Slots should be no more than 18 inch length, allow 12 inch between slots. [Diagram 6]
• Slots should not extend more than 1/3 of the way down the hip ridge.
This is to ensure that the vent does not short cycle.
B. Cut the ventilation slot and remove the unwanted roof decking material.
• Follow the shingle manufactures installation instructions.
• Install the roong shingles up to the edge of the ventilation slot.
Care must be taken to ensure that no roong material covers the ventilation slot.
NOTE: The ventilation slot can be cut either before or after the shingles have been installed. If the slot is to be cut after the
roof shingles have been installed, it is recommended that a carbide tipped blade be used.
CAUTION: Care must be taken to ensure that the cut will ONLY penetrate the decking. The saw depth must be set to ensure
the cut WILL NOT penetrate the roof frame. It is recommended that a test cut be performed between the roof trusses to
ensure the proper cut depth is used.
3. Installation of the RidgeHawk:
A. Cut the RidgeHawk to the desired length and set aside until step D.
• To obtain optimal visual appeal install RidgeHawk so that it extends from ridge edge to ridge edge and butts up ush
against any chimneys that are located on the ridge line.
• For roofs with “T” or “L” intersection cut one piece that will extend continuously from rake edge to rake edge along
the longest length. If seaming is required, avoid seaming at the ridge intersection. See step F for further instructions
on seaming.
• For hip line installation, to obtain optimal visual appeal, install RidgeHawk from hip/ridge line intersection to rake edge.
• When cutting additional pieces, cut pieces such that they will butt up tightly against the adjoining piece. Care must
be taken so that no gaps in the RidgeHawk are present.
B. SEE DIAGRAM 7.
BEFORE installing the RidgeHawk, cut a hip and ridge shingle a minimum of 6 inches wide for each rake edge. Nail a
hip and ridge shingle at the end of each ridge. [Diagram 7]
C. SEE DIAGRAM 8.
To ensure proper performance, install a bead of asphalt roong cement 3 inches from ALL edges of the ventilation slot.
[Diagram 8]
• The bead must run uninterrupted along all edges of the ventilation slot. This will help ll in any gaps between the
RidgeHawk and the roof shingles.
• The asphalt roong cement must meet or exceeds the requirements of ASTM D4586.
