I have been reviewing various brands of ridge vents. Roofer has quoted TrimLine. I looked at it today and frankly thought it looked cheap and not likely to hold up as well compared to a Cobra or Shingle Vent II that I have also looked at. Please guide me on my choice. I need good ventilation. Location Southeast with lots of shade from trees and limbs over my home that have lots of leaves dropping in the fall. The aesthetics(looks) of the low profile Trimline is nice but the Cobra and Shingle Vent looked a lot more sturdy.
