Wet Insulation Under A Metal Roofing

Wet insulation means trapped moisture that will slowly degrade the entire roofing system from the decking to the building itself.

Wet insulation under a metal roofing.

Premature corrosion commences and the life span of the metal roof is drastically shortened even the roofing screws rust away. The metal roof has been a very popular roofing material for some time but people have just started using insulation within the roofing system as a means to block out sound and keep heat in. Here we share the most common mistakes people make when installing flat roofing insulation. Between the ceiling of the house and the metal roof you might have a layer to act as a water barrier another one for thermal insulation and yet another reflective layer for insulation.

Coping with wet insulation if the fiberglass within your wall cavity or in your attic becomes wet from a leaky roof or burst pipe it will lose insulating effectiveness until the material dries out. Metal roofing is one of the most durable and long lasting roof materials on the market and can easily last for decades with little maintenance. But the greater the temperature difference the less humidity the system can handle before dripping. This is one of the dangers of using corrugated roofing on low pitched roofs.

There are many different types and installation methods out there along with a lot misinformation about which products offer the greatest energy savings. Moisture trapped inside of insulation is a breeding ground for mold and bacteria. Metal roofs are made from steel copper or aluminum panels. Installing metal roof insulation is not a difficult.

Roofing insulation is one of the most important and misunderstood building components. The problem with using insulation alone. Trapped moisture encourages corrosion of roofing fasteners and rusting of steel studs and wall ties which reduce wind uplift ratings. The goal of insulation is to keep the inside to outside temperature difference low enough at a specific humidity level to prevent it from reaching the dew point.

They are used in commercial and residential structures to protect against weather and other exterior elements. The reflective layer applies in hot regions to resist the build up of heat in the building.
