To end your ridge vent installa-
tion follow this procedure.If last
piece of RidgeMaster needs to be cut
because it is too long, measure length
to be cut, add 1/2" to measurement
and cut off squarely with knife.
For RidgeMaster Plus use
built in Shingle Alignment
Guides to evenly space and square
11" cap shingles on vent. For Ridge-
Master Plus 9" and HipMaster 9"
follow same guides but use 9" caps.
To ensure perfectly square
placement of cap shingles
align centering notch on back of
shingle with center line along top of
RidgeMaster Plus . Align back of
shingle with horizontal lettered lines.
To evenly space cap shingles
on RidgeMaster Plus , note
whatever lettered line the back of your
first shingle falls on then use the same
lettered line for all the cap shingles.
(See line “D” in example above).
Nail all cap shingles in place
using nails long enough to
completely penetrate roof sheathing
by 1/4".
EXAMPLE: 2,000 sq. ft. attic
Ridge
Soffit
A 50' ridge with RidgeMaster installed equals
approximately 600 sq. in. of ventilation.
40'
50'
Industry Standard for
Proper Ventilation =
1 sq. ft. of ventilation for every
300 sq. ft. of attic space with
50% in ridge and 50% in soffit.
•
40' x 50' = 2,000 sq. ft. attic.
•
2000 sq. ft. 300 sq. ft. = 6.67 sq. ft.
•
6.67 x 144 = 960 sq. in. (conversion to inches)
•
960 sq. in. =
{
480 sq. in. (ridge)
+
480 sq. in. (soffit)
To complete installation,
apply a good quality roof
sealant to the outside terminal ends
of RidgeMaster or RidgeMaster
Plus where it meets the roof.
Knife back baffles on cut end
about 1/2" to create an over-
lap end. Join handmade end to last
piece of vent installed making fac-
tory end the outside terminal end
and finish by nailing to roof.

To nail cap shingles in place,
use nail guide provided on vent

(More than industry standards)
IMPORTANT: With laminated
or architectural type shingles,
the baffles on the underside of the
vent MUST sit flush on flat part of
shingles as shown and not on dimen-
sional ridges and gaps part of shingle .
