In order exhaust heat from your roof you need a soffit vent to bring in the cool dry air you need.
While the focus of attic and roof ventilation is often on exhausting stale attic air, this exhausting can only happen if the flow of air is balanced between the intake of air into the bottom of the attic and the exhaust of hot, moist air out of the top of the attic.
If your attic has eaves which are not blocked from the attic air space, then the simplest air intake for your roof ventilation is Soffit Vents. Our all aluminum Soffit Vents (also known as Eave Vents) are corrosion resistant, easy to install and available in a wide variety of colors. They are rust free and very durable (22 gauge aluminum). The 1/8th inch opening between the louver blades will keep out insects, birds, and animals, thus allowing the air to move through the vent without resistance. Will keep a long lasting, clean appearance, available in over 30 colors to match the exterior of your home. Manufactured in the USA!
