Small confined areas, such as storage sheds, are prone to condensation. This condensation often occurs on the roofs of the storage shed where the cold air outside meets the warmer air inside. Unfortunately, condensation can cause mould and mildew growth, wood rot, and insect infestations. Moreover, the water may drip down onto the items in your storage shed and ruin them. Fortunately, there are some things you can do to stop condensation on storage shed roofs.

Instructions

  1. 1

    Put on protective eye wear, gloves, and an N-95 respirator makes. If there are condensation problems in your shed, there is a good chance there are also mould and mildew problems. Wearing protective gear can help minimise your exposure.

  2. 2

    Wipe moisture from the underside of the roof panels with a cotton towel.

  3. 3

    Attach polystyrene tiles to the underside of the roof using glue designed for bonding polystyrene to metal or wood (depending on the type of roof). As an alternative, you can attach a vapour barrier with a perm value of less than 1.0, such as polythene film, asphalt-coated papers, laminated papers, or kraft-backed aluminium foil.

  4. 4

    Reduce the moisture from the air inside the shed. In homes, it is common to use a dehumidifier to remove moisture from the air. However, if you do not have an electrical socket in your shed or simply do not want to run a dehumidifier in your shed, consider placing open containers of chemicals that absorb moisture. These chemicals can be purchased at industrial chemical supply stores and include silica gel, activated alumina, anhydrous calcium sulphate and molecular sieves.

  5. 5

    Increase ventilation. Proper ventilation can prevent condensation in your shed. Increasing ventilation can be as simple as installing windows. You can also install ventilation fans to provide regular air circulation.
