Proper Attic Ventilation Calculations

Not many people pay close attention to their roofs, even fewer people pay close attention to their attic ventilation.
When constructing a proper roofing system, the three critical components are: the dry in material, the roof system surface material, and the VENTILATION.
If a roof system isn’t ventilated properly, it can drastically reduce the life span of your roofing system, by trapping super hot air inside the attic- which causes extra and unnecessary heat exposure to the asphalt shingle!
Not only can improper ventilation reduce the life of the surface materials, but it can also make your home impossible to heat and cool PROPERLY.
