Ventilation FAQs

LP2 Low Profile Ridge Vent

What’s the advantage of using LP2 ridge vents over traditional fans, turbines and louvers?
With the Weather-Tite LP2 Ridge Vent, you get a roof ventilation system that is less expensive and simply vents the attic space better than traditional systems.

How easy is it to install LP2?
The screw bed and industrial-strength peel-and-stick adhesive pre-applied to LP2 means this roof venting product can be installed by just one person in three easy steps.

What types of materials are used for the LP2 ridge vents?
LP2 is a green building product–made from our nonfabric-covered Python vent recycled material. It’s a strong, durable modified polyester that never breaks down.

How well does it fit with standing seam metal roofs?
Custom contours keep dust, pests and water out, and bring air through the attic space. The low profile of this ridge vent works with any pitch of roof and with most all major metal roof profiles.

I want a ridge vent that is completely invisible. Can LP2 fit the bill?
Absolutely. With the custom contoured fit and low profile, the only people who will know the ridge vent is there is the installer and owner!

We have stringent building codes. Does LP2 comply with ridge vent building codes in my area?
Yes. When properly installed with soffit or intake vents, LP2 is building-code compliant.

Flex-O-Vent Universal Venting Material

What type of standing seam roof can use Flex-O-Vent?
The “one-size fits most” description is what gives Flex-O-Vent its name. It fits most panels of standing seam roofing. You won’t find a more versatile venting product anywhere.

How easy is it to install Flex-O-Vent?
One man can install this roof ventilation material with no problem. A double bead of M63 adhesive holds it in place until the ridge cap is installed. Flex-O-Vent can easily be cut with scissors.

What is Flex-O-Vent made of?
An extremely durable, tear-, flame-, and clog-resistant polyester. The rubber texture won’t scratch metal roofing panels while you are venting the ridge.

Will Flex-O-Vent get clogged?
This ventilation material will not clog while it prevents insects, animals and snow from entering attic spaces.

Is it expensive?
Flex-O-Vent is an extremely cost-efficient venting solution. It also provides substantial savings in utility expenses. And because of its durability, you won’t need to replace Flex-O-Vent any time soon.

Python Single-Layer Ridge Vent

Why is Python an ideal material for attic venting?
It’s a modified polyester, non-woven, non-wicking, fiber-based matting that has no external baffle, so dirt and snow trapping is greatly reduced. It helps keep out insects, dust, and moisture. And as a fascia vent, it helps eliminate mold build-up.

What type of buildings can incorporate Python?
Python is for use with all roof applications. And with many sizes available—including for just about any fascia, you can take advantage of all the Python roof venting benefits on almost any building project.

How easy is Python to install?
Python is a light and flexible venting product that is very simple to install with no difficult fitting or wrapping. It arrives in a coil, and because you can use every inch of it, there’s no waste.

Is Python made from recycled materials?
Yes–it’s a green building product for attic venting. It’s made from more than 90% recycled plastic material (more than 30% post consumer content).

Is this venting product visible under the ridge cap?
Because of Python’s low profile, you won’t see any puckering or buckling.

What type of roof pitch is required?
An ideal product for venting attics, Python must be installed on roofs with a minimum of 3/12 pitch (14°)
