How Do I Fix the Condensation in My Falls Church Roof?

Water spots on the ceiling, bubbling or peeling paint, and a musty odor coming from the attic are all signs of water damage and, in many cases, indicate a leak in the roof. However, many homeowners don’t realize that not all water-related problems originate from outside. Sometimes, the moisture comes from inside the roof space.

If you find water in the attic that isn’t from a leak, your first question is likely, “How do I fix the condensation in my roof?”  Here, Low Cost Roofing, the premier roofing contractor in Falls Church, explains how the problem starts and what to do about it. 

The Cause of Roof Condensation 

Problems with your home's ventilation system and excessive humidity in the attic or crawlspace are the most common culprits of roof condensation problems. 

When warm, moist air from the lower levels of your home rises into the attic, it cools when it comes into contact with the roofing materials. When the ventilation system is the right size and works as it should, that air escapes outside without any issues. However, if the warm air cannot escape, it condenses as it cools and releases moisture as water droplets. 

Condensation can occur anywhere in the attic. Some of the most common areas are the exhaust ducts that carry humid air from the bathroom outside and air conditioning ducts. However, the moisture can build up on the rafters and roof deck and drip onto the floor into puddles, which eventually seep through and cause water spots on the ceiling. 

The Effects of Roof Condensation 

Excess moisture in the attic isn’t just a cosmetic concern. The water can lead to numerous problems that require extensive repair, including:

• Damage to attic insulation
• Damage to the roof rafters and decking due to rot
• Mold growth 
• Electrical problems from water in sockets 
• Pest infestations 
• Structural damage to your home 

The potential for widespread and significant damage makes addressing roof condensation a priority.

What To Do About Roof Condensation 

Finding water in the attic will have you asking, ”How do I fix the condensation in my roof?”

The first step is to address ventilation system issues. Correctly sized and placed vents direct airflow outdoors, stopping moisture formation in the attic. Also, make sure the attic vents in the soffits are clear of debris to support airflow.

Replacing or upgrading attic insulation can also help reduce condensation. Insulation blocks heated air from lower levels from filling the attic. Installing a vapor barrier can also help by letting moisture escape while keeping heat inside the home.
