Air in (intake vents). Air out (exhaust vents). That’s attic ventilation in a nutshell. But it’s not always that simple depending on the complexity of the roof’s configuration. We asked roofing contractors who attend our best practices in residential attic ventilation seminars: "What roofs are the most challenging to properly ventilate and why?" These roofers did not design the houses, nor did they build them. But they were hired to replace the roofs and address the attic ventilation.
Listen to our Podcast episode: Improper Attic Ventilation Reduces Shingle Life 24% where we discuss how roofing professionals report a 24% reduction in shingle life and many documented problems to the shingles due to improper attic ventilation.
