Attic ventilation is a key roofing design element. Proper ventilation helps prevent the damage caused by trapped heat and moisture, the kind that may require extensive roof repair. In today’s post, local roofing company Pritchett Roofing Inc. shares a look at the problems that arise from poor attic ventilation.
The quickest way to determine whether or not your attic has proper ventilation is to climb into it. If the attic feels hot and humid, your attic may not be getting enough airflow. Ideally, attic conditions should be more or less the same as the outdoors, or perhaps a room in the house that doesn’t have air conditioning but has open windows. Other signs of high humidity levels in the attic include “sweating” walls, rusty streaks from nailheads, and clumping insulation.
Warm and humid air naturally rises, which is why a typical sloped roof has exhaust vents at the ridges. Releasing warm and humid air creates negative pressure in the attic, which pulls fresh air from the intake vents located at the soffits. Airflow in the attic is created as this cycle repeats. An attic with poor ventilation can be corrected by a capable roofer without needing roof replacement.
The following are common problems caused by poor attic ventilation.
