Why Our Roofing Systems Need Ventilation

roofing ventilationA sign of a quality roofer will at your roof, the shingles and the attic as part of a thorough inspection. People often wonder why roofers are so curious about the attic space. The fact is that proper attic ventilation is just as important as quality shingles and secure flashing. Without good airflow, the roof will fail prematurely and result in costly repairs. The professional at Paradigm Roofing remind homeowners of just how important good ventilation in the attic is.

Cool the Roof Deck

Air should flow through the attic at a steady rate. Roofing construction allows for vents in the eaves and gables and along the peak. Fresh air is pulled in at the lower levels and moved along the roof deck. As it carries through the attic, hot air is pulled out of the home. This cools the roof deck and preserves the shingles.

The Damage of Heat

McKinney roofing company often finds damage from excessive temperatures in attics. Plywood decking delaminated and comes apart. The framing can warp and the shingles can disintegrate. In extreme cases, the vinyl siding on the home can even start to buckle. This is why it’s important to maintain adequate air flow in the attic.

Moisture is a Threat

Poor attic ventilation not only leads to high temperatures, but it also results in high humidity levels. Moisture can form in the attic, but it will not dry out adequately without good airflow. Mold and mildew start to form, and that can destroy the insulation and cause structural damage to the property.

Prolonging the life of your roof is easy when you start by looking at the airflow in the attic. Residential roofing understand how important this is, and that’s why an experienced contractor will always ask to look in the attic. If you need a new roof, or you have concerns about your attic temperature or airflow, Paradigm Roofing can help. They’ll provide you with a thorough inspection and advise you on necessary changes.
