Static Roof Vents

1.) POSITIONING THE VENTS ON THE ROOF

Position the vents evenly spaced across the roof, below the ridgeline so that the vents can

only be seen from one side of the house, yet no greater than 2 feet below the ridgeline.

2.) DRILL THE GUIDE HOLE

Adjust placement of the vents to avoid drilling through any rafters. Drill a guide hole near the

center position of each vent.

3.) OUTLINING THE HOLE

Mark correct diameter for the vent you have selected using the chart below.

4.) CUTTING THE HOLE IN THE ROOF

Using a saber saw, cut and remove all the roof shingles (and deck) inside the diameter circle you

have marked. Next, cut back approximately 1-inch of the SHINGLES ONLY out of the top half of

the hole to allow roof for placing and positioning the ﬂange.

5.) POSITIONING THE BASE

Make sure the base ﬂange parallels the ridgeline of the roof. Slip the upper half of the ﬂange

under the shingles. Center the unit over the hole. When installing the B-144 make sure the dome

is level with the roof line. For the SLP61 AND SQP61 the shingles should stop at the midpoint of

of the flange while still covering the nails. For all static roof vents the shingles should lay on top

of the flange all the way down to the lower side of the opening. The flange from this point should

rest on top of the shingles.

If nail holes are provided in the vent they should be used for

roof deck.

6.) SECURING THE BASE

Attach the ﬂange securely to the roof with at least 8 galvanized rooﬁng nails. Nails should be at

least 2

" long and should penetrate the vent, shingles and decking. Use a nail in each corner of

the ﬂange and along the middle of each side of the vent. Use caulk to seal around each nail. If

ﬂange ribbing is present, vents should be shingled down to side ﬂange ribbing only.
