Quarrix AtticDefense Ridge Vent
$64.95 – $124.95
Item# QRX-ADRV
Product Summary
The Quarrix AtticDefense® ridge vent ensures dependable protection that provides continuous airflow throughout the attic. Made of polyester-fiber material, AtticDefense is the superior-choice among soft-roll ridge vents. The non-wicking, non-woven material is designed to keep rain, snow, and insects out of the attic. It will not compress or flatten over time, nor will it breakdown and clog compared to naturally derived mesh materials that use coconut hulls and fabric covered vents. The low-profile design virtually disappears on the roof when installed yet exhausts warm attic air to create a balanced system. Compared to HDPE ridge vents, AtticDefense ridge vent is considered more flexible and lightweight, a value choice that is easy-to-install and delivers continuous ventilation for a cool and dry attic.
RoofingDirect.com offers an excellent selection of ridge vents made of high quality materials for your next job. Our team has decades of industry experience and is ready to serve you. Please contact us, and we will be happy to answer any questions.

Unfortunatley, the Quarrix AtticDefense Ridge Vent cannot be compressed further. This would also cause it to ventilate differently from what is intended.
I have a standing seam metal roof with ridge vent which leaked during a wind driven rain storm. Does this system fit under the metal ridge vent, then re-install the metal cap and what about the raised ridges of the metal roof panels?

The Quarrix AtticDefense Ridge Vent could fit under the cap depending on the space you have on your roof. The thickness for this product is 7/8", although I do not recommend it to be used on a standing seam metal roof. It is designed to be used more with asphalt shingle roofs.
can we put this venting material down with adhesive or does it need to be nailed in?

You would want to nail it down to ensure proper installation. This product comes with a roll of 1 3/4" coil nails.

Quarrix flex vent so much better than narrow foam strips normally used with metal roofs.

It was pretty close to what thought would be. I did think it would have been a bit harder so not to crush. My concern over time will the shingles get loose!as it smashes down from snow–wind jiggling!!! Ineed another 50′ ,, but not sure if getting more!!! it is chaeper than Omni but not as firm!(((There are several omni–I’ld get the 16″ per foot venting))
