Metal Roof Condensation In Attic

Water found in these places is commonly caused by condensation in the attic.

Metal roof condensation in attic.

How to stop condensation on a metal roof step 1. This video shows what a significant condensation problem can look like. When temperature and humidity conditions reach dew point moisture can condense on the underside of metal roofing and potentially cause water damage to the inside of your customer s building. Finding water damage on the wall or ceiling is worrying for any homeowner.

That excess moisture ends up as drops of condensation on the roof. Attics are much like an oven. Picture a cloud of moisture floating overhead between the rafters. Those drips from ceilings and surface moisture occur when warm air comes in contact with the cooler roofline or walls.

This heat also affects the building materials used to construct the ceiling. Inspect the house by looking for vents that flow into the attic such as bathroom and kitchen exhaust fans. Oftentimes people will insulate their metal roof with vinyl backed fiberglass insulation to prevent humid air from coming into contact with the cooler metal roof which may be at or below the dew point. Essentially condensation occurs at night when the temperature inside a building is warmer than outside.

As it cools it can t hold as much moisture. Line the attic. Good installation and ventilation means no condensation when installed on standard residential construction consisting of typical attic insulation proper and well functioning ventilation and roof decking metal roofs do not pose a condensation risk. Fixing this issue can be less costly than replacing a roof but it should be addressed as soon as possible.

Check for short circuits that may be causing moisture such as ceiling fans unsealed light fixtures and vent. Warm wet air rises and meets the cold roof and cools. If you are heating or cooling a building adding insulation would certainly be a good idea.
