depth of blade to avoid cutting rafters or trusses.
Refer to drawings below for slot dimensions.

IMPORTANT NOTES 
1.When using standard flat 3 tab shingles, it is unnecessary to caulk under flange of the vent.
2.Caulk between low areas of shingle and flange of vent, making sure you don’t plug drain holes.
3.When applying vents to shakes, fold felt as shown in drawings on other side.
4.Before fastening vent, make sure filter is secured between shingles and vent.
5.When installing vent in cold weather, leave a 1/8 gap between vent sections to allow for expansion in hot weather.
6.See instructions below for cutting slot.
7.For best appearance, run the ridge vent from end to end to give the roof a more even, attractive appearance.
8.When using a nail gun to install cap shingles over the ridge vent, special care should be taken. It is important that the roofing 
nails penetrate the roof deck without compressing the ridge vent. Nails driven too deep will dimple or distort the cap shingles. 
Nails not driven deep enough may allow the ridge vent fasteners to back out of the roof deck and could result in blowoffs.
NOTE:Air Vent’s written warranty for this product shall not apply in any instance in which the product was not installed in accordance with the instructions contained herein.

Thanks for choosing ShingleOver
Filtered Ridge Vent!
This product is engineered to provide the best, most 
efficient ventilation system available. When properlyi
nstalled, ShingleOver Filtered Ridge Vent will:
• Help prevent the premature deterioration of shingles and 
other roofing materials caused by inadequate ventilation.
• Meet typical roof shingle warranty ventilation requirements.
• Help prevent attic heat buildup and ice dams by 
continuously moving air along underside of roof deck.
For best results install adequate
intake vents
ShingleOver Filtered Ridge Vent is designed to exhaust
moistureladen air from the attic. To achieve optimum 
ventilation efficiency, existing roof vents, turbine vents 
and gable vents should be removed or plugged, and intake
ventilation must be installed at the soffit or eave. Products
such as Air Vent’s Continuous Soffit Vent, Vented Drip
Edge or Undereave Vent provide the necessary intake 
v
entilation for optimum performance provided the intake 
net free area matches or exceeds the exhaust net free area.
ShingleOver Filtered Ridge Vent is 
asnap to install!
