Underside of metal roof.
Place the first screw.

When condensation starts to form on the underside of the roof it is absorbed by the fleece material.
Underside corrosion if the metal is improperly coated on the underside of the panel corrosion could take place.
What causes condensation problems on the underside of metal roofs.
Be sure the larger edge is laid so that the small edge of the next panel will overlap it.
Warm air holds more moisture than cold air.
Chris explains that there are two important things to remember with condensation and they may seem somewhat counterintuitive.
This occurs when water molecules get trapped underneath between the panel and the insulation or underlayment which can cause the metal to weaken if not coated.
