Condensation In Attic

How does condensation get in the attic.

Condensation in attic.

Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. Moisture forming on the glass window panes or other flat surfaces. If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck. Improper ventilation and insulation of home attic space can produce high humidity levels and trap.

This isn t usually a problem. A thin layer of moisture versus large water droplets can mean the difference between a future major roof repair or not. Insulation is responsible for keeping warm air inside your living space and out of the attic where it can lead to condensation. Sometimes attic condensation is the result of an attic being improperly ventilated.

It is common for poorly vented and insulated attics to develop attic condensation. Condensation in attic our attic has some condensation which was particularly bad when we had the cold snap. It can also cause mold to grow on roof sheathing trusses rafters and ceiling floor. Traces where water has trickled down the walls.

This accumulation can leak through the attic floor and into your living space. Signs of condensation in the attic may include the following. During the winter attic condensation can turn into frost. Attic condensation most commonly occurs when warm moist air from other areas in the home rises into the attic space.

Left alone moisture can cause everything from musty smells mold on wood and insulation and of course rot. Attic condensation during the winter can decrease the effectiveness of insulation and over time can cause significant damage to structural elements in the attic such as rafters or trusses. Condensation in attic spaces can be alarming depending on how much you re seeing. Check your ventilation system.

Moisture accumulation is most significant when outside temperatures are very cold because air holds less moisture as the temperature decreases. This condensation can form droplets of water and accumulate into the insulation below. In order to boost air flow one can install an attic fan. As a result a lot of our things up there are mouldy and had to be thrown away.

To save time and better pinpoint the problem you can hire a professional to inspect your insulation and fill any gaps that might be letting warm air into the space. As warm and moist air comes into contact with the cool underside of the roof condensation occurs. Adding a few vents to the floor of the attic that extend to the ceiling of the story below the attic can help to promote air flow within the attic. And the same factors that cause attic condensation problems also cause ice build up on roof edges which can lead to ice damming.
