Later on in my post I will get to talking about the importance of roof ventilation. But for now I wanted to share with my fellow bloggers the most common venting system I use, and what product I use for it. For all most all my jobs when installing ridge vent I use a product called Cobra. The reason being Cobra Ridge Vents Low profile fiber mat lets the maximum airflow, and yet it prevents water and insect infestation. When you are driving along take notice at the top of a house you will see some that are flat and some that are raised. The raised is because the home has ridge vent. I swear by this product it is one of the best out there.
