I have two wind turbines (relatively new) on my south facing roof and are rated for ~120 mph winds (or so the box said)... I have multiple roof lines and the other parts of my roof has ridge vents.... I did not want any ridge vents running entire crown of my roof that faces south so I put up a couple of turbines... hurricane force winds drive water into ridge vents

if winds are expected to be greater than 120, should you.....
- cover and duct tape them with mutiple thick contractor garbage bags
- remove them ( then you have to deal with holes in roof)
- or just let them spin and hope for the best....

For Ivan I just let them spin but we didn't get any hurricane force winds in MS....

is there a special type of coverage available on the market to cover them?
