GAF Master Flow Square-Top Roof Louvers with Round Throat

GAF Mushroom Shingle Ventilator is perfectly suited for your shingled roofing job.

At first it may seem odd to add insulation for warmth and then purposely allow cold air to enter the attic through vents, but this combination is the key to a durable and energy-efficient workplace, office, or home.

Here's why: in the winter, allowing a natural flow of outdoor air to ventilate the attic helps keep it cold, which reduces the potential for ice damming (snow that melts off a roof from an attic that is too warm and then re-freezes at the gutters, causing an ice dam that can damage the roof).

Proper insulation with the Empire Mushroom Shingle Ventilator, along with air sealing, also keeps attics cold in winter by blocking the entry of heat and moist air from below. In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture.
