Sweating Roof Problems

Primary hyperhidrosis may be at least partly hereditary.

Sweating roof problems.

How to stop a metal roof sweating 5 key points to solving your shed condensation problem metal roof sweating is a result of excess humidity condensing on the underside of your roof. As it cools it can t hold as much moisture. Later designs such as the use of selectively permeable membranes are also not immune to the effects of roof vent loft condensation problems. If excessive sweating has no underlying medical cause it s called primary hyperhidrosis.

Metal roofs are known for this with condensation forming particularly at the beginning and end of a day. If your roof deck or insulation is developing water droplets chances are your forehead is too. It is typically caused by excess moisture inadequate ventilation shoddy workmanship or some combination of these factors. It happens when excess sweating is not triggered by a rise in temperature or physical activity.

That excess moisture ends up as drops of condensation on the roof. Roof condensation is a thorny but fairly common problem. If the excess sweating is due to an underlying medical condition it s called secondary hyperhidrosis. Picture a cloud of moisture floating overhead between the rafters.

Although the use of the completely impermeable and the selectively porous roofing styles may cause roof condensation problems it is actually very important and somewhat indispensable. Warm wet air rises and meets the cold roof and cools. It can lead to roof leaks even if rain has not occurred for several days. 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. Condensation happens when moisture filled air contacts anything that is below the dew point temperature.
