Our Round Back Vents are excellent at venting attic spaces for sloped shingle roofs.
The Round Back Vent exhausts out hot air from the attic in the summer and moist attic air from the attic in the winter, while preventing rain and or snow from entering the roof. The Round Back Roof Vent is UL certified and has been tested to withstand wind pressure greater than 200mph. Having a round design makes the Round Back Roof Vent aerodynamic, thus allowing it to deflect wind and objects carried by the wind. Insects and vermin will also not be able to penetrate the roof vent.
Other affordable roof vents tend to be made of galvanized steel. Galvanized rusts and you can see those roof vents creating rust streaks down people’s roofs. Our Round Back Roof Vent will not rust, they always look like new, even years later.
The Round Back Roof Vent low profile design is appealing to the eye and with various color options, your roof will always look beautiful.
Static Roof Vents
Roof vents and attic vents have many engineering terms used to describe them. One of these terms is a static vent. One may ask the question, why that name? The answer lies in the definition of the word “static”, which is stationary or not moving. Static vents are very popular with architects, engineers and roofers due to the fact that they have no moving parts. Needless to say anything that has no moving parts to wear out will last a long time. This is true in the case of a roof vent or static vent that has no moving parts, the static vent will last the life of the roof. The only time a static vent has to be replaced will be when a there is a re-roofing. The only reason it will need to be replaced is because the flange that gets nailed or screwed to the roof becomes unusable when removed. Between the nails or screws and the roofing sealant, the flange gets all bent up and distorted when removed.
Since the cost is so low for a static vent, it is much easier and economical to just buy a new one and replace the old static vent. Generally speaking all static vents are good vents. All they are is an umbrella over a hole. The challenge has been to make them appealing to the eye and as low a price as possible. AVP’s Round Back Vent is a simple classic example of a static roof vent, ideal in many applications, available in several configurations in addition to these flat flange vents below.
