A Guide to How Condensation Affects Your Home's Metal Roofing, Clarksville, Maryland

Metal roofing is a fantastic option for your home because it is highly durable and energy-efficient. But just like with any roofing material, certain problems can arise. One of the most common is called metal roof sweating. This is when condensation accumulates on the underside of the roof, and if it’s not fixed, it’ll lead to major problems. Here’s more information about how this occurs and how to prevent it.

Why Metal Roofing Accumulates Condensation

This problem is most widespread in areas with high humidity and temperatures that drop below the dew point, but it can occur in any environment. It happens when the warm air inside of the home rises up towards the ceiling. As it does this, it carries moisture up as well, and once the warm air comes into contact with the cooler roof, the moisture condenses and accumulates on the underside of the structure.

If it’s not removed quickly enough, the metal can begin to corrode, which leads to repairs or replacement. If the moisture comes into contact with the wooden foundation, wood rot sets in and weakens its structural integrity. Also, any insulation that’s underneath the condensation becomes damp, which increases the possibility of mold or mildew growth.

How to Prevent Metal Roofing Sweating

Metal RoofingLuckily, there are a handful of steps you can take to prevent this problem from occurring. One simple solution is to keep the humidity levels in the home between 30 to 50 percent. You can do this by using an HVAC solution and a dehumidifier inside the house.

It’s also important to ensure you have proper ventilation around the roof. This keeps the air moving so the water is less likely to condense and cling to the underside. Ventilation holes at the eaves level of the roof and vents in all elevated portions can mitigate the problem.

Also, a layer of insulation on the underside of the roof will prevent the temperature from dropping below the dew point. Sprayed insulation or bonding thin sheets of insulation to the underside are popular options for metal roofs.
