Don’t Pay Too Much to Heat & Cool Your House
Poor attic ventilation can ruin insulation, destroy shingles and raise energy bills. Poor insulation allows heat to move through ceilings, which can account for a 30% increase in your total heating and cooling costs.
The Federal Housing Administration recommends a minimum of one square foot of attic ventilation (both intake and exhaust) for every 300 square feet of attic space. The amount should be divided equally between intake ventilation systems (soffit vents) and exhaust ventilation (roof vents).

How Insulation Works
It may seem odd to add insulation for warmth while purposely allowing cold air to enter your attic through the vents. However, this combination is key to a healthy and energy-efficient home. In winter, outdoor air helps to keep your attic cold, reducing the potential for ice dams. Proper insulation and air sealing ensure that cold air stays in the attic while blocking heat from escaping the living area below. During warmer months, venting allows excess heat to escape your attic, protecting roof shingles from “frying,” while insulation prevents your air conditioner from working overtime by creating a barrier between your living space and the attic.
Insulation products range from traditional rolls and batts to loose-fill (blown) and spray-foam insulation. Let our experts help you determine the right product to make your home more energy-efficient.
