Proper Ventilation for Your Roof
Making sure your attic and roof are properly ventilated is essential to ensuring a long life for your roof and for preventing the formation of damaging ice dams. Proper ventilation also extends the life of your roof.
Poor ventilation can substantially shorten the life of your roof by allowing heat and moisture to build up under the roof deck. This puts extra stress on the roofing materials, which can warp, deteriorate or become spongy; or mold and mildew can form on the deck material.
Stop Ice Dams with Ventilation
An imbalance in the temperature of the roof during the winter months – cold on the outside and warm underneath – can lead to ice dams. These form when a warm roof melts the bottom layer of snow or ice, which then flows down to the edge of the roof. Once there, the melted water is once again exposed to cold temperatures and refreezes, causing a buildup of ice (“ice dam”) to form. The ice dam can cause water to back up into your home where it can cause serious structural damage.
Muth & Company Roofing designs roofing systems that incorporate intake vents under the edge of the roof eaves, which allows fresh air to flow into your attic. The ridge vents at the peak of the roof allow stale air to leave the attic space. This circulation of air helps prevent heat and moisture from building up and rotting out your roof deck.

How Does Ventilation Impact Your Roofing System
Proper ventilation directs airflow through your home and attic space and controlling this airflow protects the roof deck and can increase the life span of your roof. The roofing system includes your insulation, ventilation, gutters, underlayments, and finally shingles. Roofing systems that have proper ventilation, are well insulated, and installed with the craftsmanship and good products last longer than roofs that lack a piece of the system.
