Harden Your Home with No Headaches. Install BrandGuard Vents.
Compatible with retrofit and new construction builds, BrandGuard Vents offers flexible, ember-resistant solutions for a wide range of residential and commercial designs.
Building a new construction residence in California? Meet local fire building codes by specifying BrandGuard’s CAL Fire Approved Dormer Roof Vents. Specify these ember-resistant vents just like any standard roof vent.




Looking to meet local wildfire building codes and/or protect your attic space from wind-blown embers? Simply remove your current roof vents and install BrandGuard’s Ember-Resistant Roof Vents into the existing vent opening. Use product-appropriate screw fasteners and exterior-approved clear caulking with a minimum 30-year warranty.

Step 1: Measure and Prepare
Measure the outside dimensions (W x H) of your existing vent before cutting. Order the correct BrandGuard retrofit vent and sub base product. Please note we offer custom sizes as well. If your roof is made of concrete or clay tile, consult your tile manufacturer for safe walking instructions to avoid cracking tiles.

Step 2: Modify Existing Vent and Position New Vent
Position the BrandGuard Soffit Vent over the opening and align it evenly. Mark the screw holes if needed, then drill pilot holes and secure the vent using corrosion-resistant screws. Make sure the vent sits flush against the soffit surface and is tightly fastened to prevent gaps or movement.

Step 3: Secure, Seal and Final Inspection
For added protection, apply caulk or sealant around the edges of the vent to improve airtightness and keep out moisture and pests. Finally, inspect the installation to ensure the vent is secure, unobstructed, and properly aligned. Your home now has upgraded to WUI-approved protection.
Compare vent models by size, airflow, material, and compliance ratings to find the right fit for your project.

The essential questions, answered.
Home hardening is a critical factor to improve the survivability of structures during wildfires. All homes have vulnerable “point of entry” that must be sealed to avoid hot embers and fire from entering the structure. Home ventilation is essential from an energy saving point of view, however in case of a fire nearby, there is a risk of hot embers finding their way into your attic, basement, garage, etc. BrandGuard has patented a unique system to keep embers from entering your house. Our design consists of multiple line of defense:
BrandGuard Vents resists the intrusion of flame and embers into your attic through the building’s vents, thus protecting your home from dangerous flying embers created by wildfires.
Standard Vents do not offer any protection against flying embers and fire.
Baffles have long been used in commercial kitchens as a way to prevent stovetop fires. We have redesigned them to help keep flames, dangerous burning embers, and radiant heat out of your home during a wildfire. Baffles provide immediate protection during a wildfire from the very first second of exposure.
Another reason baffles are better is because they provide protection from driving rain, snow, and rodents. Our vents have passed stringent driving rain tests in Hurricane labs in Florida keep heavy driving rain out at even 140mph! Rodents are unable to chew or squeeze through our vents like they do with regular mesh vents, making them an excellent option for pest control!
BrandGuard Vents are equipped with a propriety material (intumescent) which expands in case of fire. The thermally activated strip expands up to 30 times its original thickness, sealing off the vent completely. This is an extreme measure to make sure that fire doesn’t penetrate the home.
Yes, BrandGuard Vents will work with you and your needs to create a custom fire prevention vent for your project.
BrandGuard Vents are installed like any traditional vent with the same footprint. Our line of retrofit fire Vents can be easily inserted over existing vents without any damage to the structure. They are held in place by applying appropriate screw fasteners. They can also be installed from inside the attic. Please see our installation instructions.
