Next Generation Soffit Vent: A Safer Way to Vent Your Home
When it comes to home ventilation, what your contractor doesn’t know can cost you significantly—both financially and in terms of your family’s health. Traditional roof venting might seem like a simple solution, but did you know that roof penetrations substantially increase your home's risk of leaks, mold, and structural damage?
Why Traditional Soffit Vents Fail
Many contractors are aware that conventional soffit vents can cause dangerous backdrafts, pulling moisture-laden exhaust air back into your attic. This can potentially lead to black mold and compromised indoor air quality.
Enter the PreVent-It® Soffit Vent
Unlike traditional bathroom soffit vents, our patented design safely moves bathroom exhaust air away from your attic, preventing it from re-entering through the soffit’s passive intake system.
With our innovative product, soffit venting is not only safe and effective, it is also ideal. No more mold. No more moisture. No more risk.

How Our Soffit Vent Protects Your Home
The patented design of the PreVent-It® Soffit Vent eliminates the risks associated with roof vent installations—no leaks, fewer repairs, and better overall home health. This cost-effective solution is easy to install, fits neatly into soffits of various sizes (12 to 48 inches), and meets International Code Council ventilation standards.
For decades, contractors have been cutting holes in roofs to vent bathroom exhaust fans. But here's the problem: roof penetrations invite problems—leaks, warranty issues, exposure to the elements, and added labor risks.
Our bathroom soffit vent provides a smarter, safer alternative
No more holes in the roof
This under-eave vent installs under the soffit—not through the roof—protecting your shingles, your attic, and your investment.
Keeps your home healthy
Unlike standard soffit vents that dump moist air back into the attic (where it fuels mold and wood rot), our patented design removes 95% of the exhaust from the soffit’s passive air stream, preventing reentry.
Protects roof warranties.
Roof penetrations often void roofing warranties. With our soffit vent, your roof stays sealed and your warranty intact.
Easier, safer installation
No climbing on steep roofs. No messing with custom roofing materials. This soffit vent is safer for installers and faster to put in.
Proven by science
Independent airflow studies and CFD analysis show our design outperforms traditional options—pocket vents, gable vents, sidewall vents, and yes—roof vents.
Saves money on repairs
Moisture and mold remediation can cost homeowners $2,000–$25,000. Why risk it?
