Attics or roofs can be designed and constructed to be either vented or unvented in any hygro-thermal zone. The choice of venting or not venting is a design and construction choice not a
requirement determined by the physics or by the building code. The model building codes allow both vented and unvented roof assemblies. The applicable physics impacts the design of attic or roof systems as does the applicable building code but neither limit the choice. Vented attics that are not vented properly or have exhaust venting into the attic is a prime source for mold growth. Take a look in your attic to see if you have any mold growth or contact Erison Properly Inspection to peek into your attic for you.
