Hi,, I have a 2 year old single story home with a shingle roof, wich it includes an on ridge vents, in ten foot sections. During last years hurricanes, Esp francis and Jean, I had water Intrusion in 3 different places, over garage, in middle of Main(vaulted ceilings) roof and also vent over Guest room. I know this for a fact cause during hurricane I look into crawl space in garage and saw it coming from vent. builder wont replace vent, told me thier is nothing wrong with it, its a non warranty issue and laughed at me basically,, I want to avoid this before the next Hurricane comes, as we are in a Decade long Hurricane intense Activity, what kind of on ridge vent can i get to stand up to Wind Driven Rain here in Fla? Thanks

Ridge vents have become very popular in the last 10 or 15 years because they are easier to install than gable vents and provide a cleaner appearance than turbine vents. Unfortunately, ridge vents don't stop water well in hurricane velocity winds. Ridge vents have relatively low water dams and very high winds easily push water over them. Additionally, it is difficult to temporarily seal off ridge vents from inside or outside.

Gable vents are more resistant to wind blown water but they too will leak when wind velocity rises above 40 or 50 mph. However, they can be easily blocked off from inside or outside and leakage is concentrated at the outside wall below.

Regards
