What seems to be a very simple, direct question can never be so simple when working with a commercial and industrial roof. Can it be dried? What about the "R" factor? Will it be able to absorb moisture or will it make the problem worse? To understand the essence of these issues, we must first consider the problem.
When water seeps onto the surface of a commercial or industrial roof with a low inclination, water will migrate. Draw a sponge. If you pour water on one corner of the sponge for a certain period of time, then the whole sponge will eventually be soaked. The same will happen with the lowest insulation. The problem is exacerbated, depending on the type of flooring takes advantage of the roof. The Tectum deck will allow water to flow straight, the metal deck will slowly drip water, and concrete decks can hold moisture for many years before it starts to appear inside the building. Prolonged exposure to moisture in organic insulation (perlite, fiberboard, etc.) will cause irreversible damage. Like a forest lying on the ground, organic insurances will rot.
Inorganic insulation (fiberglass, ISO, foam glass, etc.) Will not decompose as organic. These are closed cell systems that will not absorb moisture and can be discharged with very little damage to the insulation. Leak repair usually removes moisture, as there is usually negative pressure inside buildings, which leads to moisture inside the building.
While your insulation is wet, the value of “R” is essentially destroyed. If you are dealing with organic insulation, the most common solution is to remove and replace the damaged area. If the problem is detected early enough, the insulation can be maintained by repairing the leak, but if it has advanced to the creation of the sunken area, it may be too late.
One-way vents are very effective for drying wet insulation. Usually, drying a damp insulation will require only one vent for every 100 square feet of surface area.
Extremely, although every situation with a roof is different. If you find yourself in a situation where you have a leak, it is always better to consult a local flat roof specialist. They will be able to assess whether your particular situation justifies repair or replacement. Also, most will offer a free, non-binding quote or suggestion to take care of your specific problem.
