The answer to 'why is my roof vent wind damage' is that roof vents can become damaged due to high winds, storms, or other extreme weather events. The vent itself or the flashing around it may become loose, cracked, or detached, allowing water to leak into your home.
Common signs of wind-related roof vent damage include whistling or howling noises from the vent, visible cracks or holes, and water stains or leaks around the vent. This type of damage is often more prevalent on older or poorly installed vents, or in areas prone to severe storms.
