People already know that almost all of the attics and roofs are ventilated. Are you aware and have you seen that ridge vent on the top of a roof?. What you may not be wary of, however, is that certain homes may not have proper ventilation or sometimes have no ventilation at all.
Now, you may wonder if it is still essential to have a roof ventilation system? Roof ventilation helps to maintain your home cooler in the summer and warmer throughout the winter, giving your roof a longer lifespan as well as a much lower chance of damage to the roof.
