Hurricane Hermine was a Category 1 making landfall on the Florida coast in August of 2016. Category 1 hurricanes have wind speeds ranging from 74 to 95 mph. Hurricane-force winds will cause damage to roof turbines or even knock them off the roof completely. AVP's Round Back Roof Vents can withstand wind speeds up to 200 mph. This customer was happy to find that there were zero leaks.
Here is a testimonial and photo:
We back up these testimonials with our UL certifications and wind pressure testing. Our Round Back Vents have certifications and are tested to wind pressures of 50+ PSF, equivalent to over 200 mph wind speeds!
