How Do You Stop Condensation On A Metal Roof Sheet

The final method of stoppoing a metal roof sweating is to bond an anti condensation layer on to the underside of the roof.

How do you stop condensation on a metal roof sheet.

Traditionally we ve insulated the roof panel to try and keep the temperature on the panel from reaching the dew point. Building timber floor to support the metal shed frame will form a barrier to block future sources of damp. Then as the temperature inside and outside equalise the moisture is released. Insulate and try to keep from reaching the dew point.

The roll of felt is spread out over the entire roof on top of the plywood and nailed down with roofing nails. When condensation starts to form on the underside of the roof it is absorbed by the fleece material. Traditionally condensation is managed by insulating the metal roof so that the panel temperature never reaches the dew point. Worse if the roof is over your shop carport barn or self storage unit you have to worry about what damage it is doing to the contents of these buildings.

Have you ever been under a metal roof that had condensation on the bottom side of it. Insert a nail every six inches along the perimeter of the felt and every foot on the inside to secure it to the plywood. This will provide flow through ventilation at the point where the hottest air rises to. If there is no high level ventilation already installed install a 15cm ventilation grille at the highest point at each end of the eaves.

It is quite annoying to have the condensation falling on you like rain. Add a preinstalled membrane to absorb and release the condensation as it forms with the natural weather cycle. No drips are formed. This is the general overview of how to solve most of the issues related to condensation in roofs.

You also have to make sure the roof space has enough ventilation coupled with interior circulation of air. This plywood will absorb the moisture and prevent condensation. You must have a vent at both ends not just one. The best way to solve the problem of condensation in metal sheds for a garden shed at least is to build a timber sub floor.
