Rubber Roof Condensation Problems

Picture a cloud of moisture floating overhead between the rafters.

Rubber roof condensation problems.

It is the leading cause of the deterioration of trusses. Although condensation in roofs may not seem like a serious problem it actually is. Despite the many benefits of using the old roofing styles which involve the incorporation of selectively porous and completely permeable membranes they are the major causes of condensation in roofs. A low roof pitch say 6 degrees or less means that as condensation collects it doesn t run down the roof slope it stays put until a drip forms which drops on to your stored belongings below.

As it cools it can t hold as much moisture. That excess moisture ends up as drops of condensation on the roof. If your roof deck or insulation is developing water droplets chances are your forehead is too. Warm wet air rises and meets the cold roof and cools.

The lower the pitch of a metal shed roof and also the deeper the corrugations the worse the problem of metal roof sweating. Essentially condensation occurs at night when the temperature inside a building is warmer than outside. Over time this excess moisture can lead to the unseen decay in roof timbers and fixings. Condensation can cause a number of problems within a building particularly interstitial condensation which can occur inside the roof s structure.
