Rubber roof condensation problems.

Condensation can cause a number of problems within a building particularly interstitial condensation which can occur inside the roof s structure. First there is little air movement within the roof system to pump moisture laden air into the roof. Usually this problem stems from either poor workmanship in installing the roof or insulation insufficient ventilation or excess moisture in the building. In the case of the timber trusses and purlins they will rot and eventually lose their stability.

It is the leading cause of the deterioration of trusses. If your roof deck or insulation is developing water droplets chances are your forehead is too. Roof condensation occurs when moisture becomes trapped between the roof and the insulation.

Although moisture problems in the roof assembly can be due to waterproofing deficiencies don t neglect the effect of condensation. But with proper design and maintenance principles you don t have to sweat roof condensation issues. And second the roof deck and rigid insulation form a reasonable interior vapor barrier. Over time this excess moisture can lead to the unseen decay in roof timbers and fixings.

Although condensation in roofs may not seem like a serious problem it actually is.
