But the greater the temperature difference the less humidity the system can handle before dripping. Moisture trapped inside of insulation is a breeding ground for mold and bacteria.

This is one of the dangers of using corrugated roofing on low pitched roofs. 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. Premature corrosion commences and the life span of the metal roof is drastically shortened even the roofing screws rust away. Metal roofs are made from steel copper or aluminum panels.

Trapped moisture encourages corrosion of roofing fasteners and rusting of steel studs and wall ties which reduce wind uplift ratings. 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. The reflective layer applies in hot regions to resist the build up of heat in the building. Installing metal roof insulation is not a difficult.
