The Effects of Roof Condensation In Winter

Roof condensation is often mistaken for leaks. Knowing how to identify which is which can help you focus your efforts in minimizing its effects in your indoor space. In this blog, the local roofing contractors at Balken Roofing shares an in-depth look at what causes roof condensation, and how to address it.

Roof Condensation Vs. Leaks

Leaks and condensation look very similar at first glance. You’re bound to find drips, as well as moisture running along the walls. Your first clue should be the weather: leaks usually happen when it’s raining, while condensation can occur regardless of weather. Since hot and moist air tends to rise, moisture tends to collect in the attic area, which is the first part of your home you should inspect if you suspect condensation or other roofing problems.

Signs of Roof Condensation

Initial signs of roof condensation won’t be as noticeable during its early stages. This is why attic inspections are an important part of maintaining residential roofing systems: the first signs will be evident in the attic. Support posts and other flat surfaces would appear to be “sweating” and dripping. Attic would be hot and humid, which you would feel once you climb in. If not addressed, moisture can seep through the ceiling, resulting in signs that are very similar to leaks.

How to Address Roof Condensation

There are two things that should be done when addressing roof condensation:

Attic Ventilation — A properly-built residential roofing system should have exhaust vents at the ridges. Since hot and moist air tends to rise, it should naturally move to the ridge vents. The air pressure created  by vented air should pull fresh air through intake vents at the soffit. Exhaust fans mounted on the roof may be necessary if not enough air isn’t vented out by the roof. In addition to preventing condensation, proper attic ventilation can also reduce the chances of ice dam formation and structural damage.

Humidity Control — Moisture in the attic comes from your indoor spaces, particularly areas such as the bathroom and kitchen. Some best practices, such as opening the windows up to 15 minutes a day to flush out excess humidity, can help regulate relative indoor humidity levels. A whole home humidifier/dehumidifier system can also help you regulate relative indoor humidity all year.
