Extreme weather conditions across the
country has increased the demand for a
weather resistant vent. Duraflo has developed
the WeatherPRO® Series line of roof vents,
which are available now through your local
distributor or retail store.
With the WeatherPRO® Series, you no longer
need to worry about extreme weather. Designed
to allow for high volumes of airflow, while
providing excellent defence against weather
infiltration, the patented WeatherPRO® internal
baffles deflect water and snow allowing for
harmless draining out the drainage openings. The
WeatherPRO® series also incorporates a patent
pending moisture control system which directs
precipitation away from the vent openings.
Combining manufacturing quality, with
Duraflo WeatherPRO® technology, and a patent
pending moisture control system, will ensure
the WeatherPRO® Series is the first choice when
weather infiltration is an issue.

Over 15 years of accelerated
weathering testing
•
Customized UV inhibitor package in all
molded products
•
All colours contain UV inhibitors
•
CSA evaluated
Evaluated and passed based on
the following criteria:
•
ASTM G 155 Accelerated Weathering
•
ASTM D 638 Tensile Strength Difference
•
ASTM D 2843 Smoke Density Rating
•

Material & UV Protection
Material - Cold Impact Tested
WeatherPRO® Upward Venting
The solid sidewalls and upward venting design behind the WeatherPRO® vents have been engineered to increase
weather protection while improving ventilation in high wind areas. The solid sidewalls work in part with the interior
baffles, providing the first line of defense against driving rain and snow. The solid sidewalls also act to push wind up
and over the cap of the vent, as opposed to under, like a traditional roof vent. This airflow over the cap of the vent
creates negative pressure to draw air from the attic.
The WeatherPRO® line of vents are manufactured from all virgin polypropylene allowing them to withstand the most
extreme climates. The material used in manufacturing the WeatherPRO® Series is cold impact tested at -40 degrees.
The material remains functional, flexible and resilient to damage even when installed with a nail gun.

INSTALLATION - PROTurbo
For New Construction
Installation of Duraflo
WeatherPRO®
PROTurbo
should comply with all
local standards and regulations.
Before beginning a job, determine
how much ventilation is required in
both soffit and roof vents and what
sizes of vent would best suit the job.
If required, refer to Duraflo Ventilation
Calculator for guidance.
- 13 -
INSTALLATION - PRO SlantBack
For New Construction or Re-Roofing
1. Determine the location of vents:
Evenly space the roof vents along the width of
the roof, marking the location of all roof vents
before cutting holes. Centre the holes between
the rafters within two feet (24”)
(61 cm)
from
the peak of the roof.
Cut and prepare the opening:
Cut the holes in the sheathing before applying
shingles, cut a 6-1/2” x 8-1/2”
(16.5 cm x 21.6 cm)
opening. Shingle up until the first full course of
shingles covers the bottom of the hole. Cut the
excess shingles away from the hole.
2. Position the vent and nail the vent
in place:
Duraflo Roof Vents have a top arrow indicator.
Make sure the throat of the vent is in the proper
position centered over the opening. Using the
pre-marked nail holes, nail the vent securely
into place.
3. Complete the shingle installation:
Continue installing shingles, overlapping
the flange of the vent. Cut the shingles around
the top of the vent to match its shape.
Installation of Duraflo
WeatherPRO® SlantBack Vent
should comply with all local standards and regulations.
Before beginning a job, determine how much ventilation is required in both soffit and roof vents and what sizes
of vent would best suit the job. If required, refer to Duraflo Ventilation Calculator for guidance.
Caution:
DO NOT USE roofing cement /
roofing tar to seal the vent to the roof. The
wide flange and molded-in water guards
will force the water down the roof over
the shingles. The polypropylene flange
is large enough and flexible enough to
effectively self seal against the roof without
the aid of roofing tars. Roofing tars are
potentially damaging to the roof vent and
the asphalt shingles. Use of roofing tar
will void any warranty on the Duraflo Roof
Vents. Optional: Seal all nail heads with an
approved sealant, such as silicone. Make
sure the sealant is a non-petroleum product
(usually available in a plastic tube).

INSTALLATION - PRO50 & PRO75
For New Construction or Re-Roofing
1. Determine the location of vents:
Evenly space the roof vents along the width of
the roof, marking the location of all roof vents
before cutting holes. Centre the holes between
the rafters within two feet (24”)
(61 cm)
from
the peak of the roof.
Cut and prepare the opening:
Cut the holes in the sheathing before applying
shingles, for PRO50 cut a 7-1/4” x 7-1/4”
(18.4 cm x 18.4 cm) opening, for the PRO75 cut a
9-1/2” x 9-1/2” (24 cm x 24 cm) opening. Shingle
up until the first full course of shingles covers the
bottom of the hole. Cut the excess shingles away
from the hole.
2. Position the vent and nail the vent
in place:
Duraflo Roof Vents have a top arrow indicator.
Make sure the throat of the vent is in the proper
position centered over the opening. Using the
pre-marked nail holes, nail the vent securely
into place.
3. Complete the shingle installation:
Continue installing shingles, overlapping
the flange of the vent. Cut the shingles around
the top of the vent to match its shape.
Installation of Duraflo
WeatherPRO® PRO50 or PRO75 Roof Vent
should comply with all local standards and
regulations. Before beginning a job, determine how much ventilation is required in both soffit and roof vents
and what sizes of vent would best suit the job. If required, refer to Duraflo Ventilation Calculator for guidance.

INSTALLATION GUIDE
Step 1.
Cut a slot in sheathing along the ridge 2” (5 cm) wide 1” (2.5 cm)
on each side of peak).
If ridge beam is present, cut a slot 1” (2.5 cm) wide on each side of the
beam. A closed area of sheathing 12” (30.5 cm) in length should be at
both ends of ridge. The 12” (30.5cm) area should be coverd to prevent
infiltration.
Step 2.
For step 2 it is recommended a chalk line be used to ensure the ridge
vent is installed straight along the roof peak.
Place the first piece of vent with female end 1/2” (1.3 cm) from the
gable end. On one side of the peak fasten the first piece using nails at
each end and in middle sections. Fold the vent over the peak and
fasten the second side using the same nail pattern. (2” (5 cm) nails are
minimum length). Continue installing additional pieces along
ridge connecting the female end over the male end.
Step 3.
When reaching the ridge end, the last vent section may need to
be cut to length. There are molded-in end caps every 3” (7.6 cm) on the
underside of the ridge vent. Measure and cut amount needed to
install to within 1/2” (1.3 cm) of ridge end.
After fastening the ridge vent to the roof peak install ridge caps
using a min 2” (5 cm) nail. The ridge caps should be centered on the
vent and sit between the outer raised baffle walls.
