Most houses need soffits. What is usually referred to as a soffit is the eaves soffit which is the area underneath the overhang of a roof. The soffit gives your home a finished look and provides ventilation into your roof through the soffit vents/perforated soffit. It helps to prevent moisture build-up, mould, mildew, and heat damage to your attic as well as prolonging the life of your roofing materials by promoting air movement on the underside of the roof. Air is sucked in through the soffits (soffit vents), circulating in the attic, and then exits via the roof vents on top of the roof. A properly ventilated soffit helps to cool your home in the summer and protect it year-round.
