Retrofit Existing Dormer Vents with BrandGuard
Want to meet local wildfire safety codes or shield your attic from airborne embers and flames? Jut remove your current roof vent and replace it with a BrandGuard’s Ember- and Flame-Resistant Sub-Base Vent. If measured correctly, the vent will fit directly into the current opening and should be fastened using the recommended screws. To finish, seal the edges with a clear, exterior-grade caulk rated for at least 30 years of durability.
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.

Frequently Asked Questions
The essential questions, answered.
How do Brandguard Vents™ work?
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:
- A baffle design which allows air to move freely, but traps embers
- BrandGuard propriety intumescent material, which expand only if high heat and extreme flames are reaching the vents
- Non combustible, metal vents which resist heat and flames
How are Brandguard Vents™ different than standard vents?
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.
Why are baffles better for protection?
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!
What is an intumescent material?
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.
Are custom vents/products available?
Yes, BrandGuard Vents will work with you and your needs to create a custom fire prevention vent for your project.
How are the vents installed?
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.
