Attic Ventilation and Insulation
A roof that cannot breathe cooks shingles in summer and grows ice and mold problems in winter. We measure your attic, calculate balanced airflow, add ridge vents, soffit vents and baffles where needed and check the insulation so heat and moisture have a path out.

About attic ventilation and insulation
How much ventilation do I need?
A common guide is one square foot of vent area for every 150 square feet of attic floor, split between intake and exhaust. Our Attic Vent Calculator does the math, and we check your attic in person.
Can ventilation lower my energy bill?
It can help, especially along with proper insulation, though results vary by house.
Can too much ventilation be a problem?
Unbalanced venting can pull conditioned air from the house, so balance matters.
