Metal roofing is growing in popularity across the country. It is easy to care for, lasts many years and doesn't present many of the problems that traditional asphalt shingles cause. One issue that some homeowners have had to resolve is condensation forming on the underside of the metal roofing. As the warm air inside your home rises and carries moisture with it, it collides with the underside of the metal roofing. Then, the cool temperature of the roofing causes the moisture condense and coat the surface. There are a couple small things to check to make sure that an easy fix isn't possible.
Inspect ceiling light fixtures. If they aren't installed properly, they will release heat into the attic space and contribute to the condensation problem. The light boxes should be insulated to limit the amount of heat that they are releasing into the attic space. If they're not insulated, wrap the box with insulation or cover it with blue-board insulation. Check the bathroom and kitchen ventilation systems. Are they pulling the air out of the kitchen and bathroom into the attic space? Sometimes, these systems aren't installed properly. When this happens, the vents pull air out of the kitchen and bathroom, but it's pulled into the attic space instead of outside.
Regulate Interior Temperatures
One way to reduce the condensation is to regulate the interior temperatures of your home to stay in line with the temperatures outside. The greater the difference in temperatures, the more condensation you'll have to deal with.
Reduce Interior Moisture
Limiting the amount of moisture that is carried to the attic space will help tremendously. Run a dehumidifier to pull the moisture from the air. Downsize your houseplant collection. Believe it or not, those plants can release way more moisture than your home needs or should be exposed to.
Insulate the Roof
Insulating the roof with material that doubles as a vapor barrier will help reduce the condensation a great deal. In fact, this could be the fix you need to be done with the problem altogether. If there's no change in temperatures as the interior air reaches the underside of the roof, there will be no condensation forming anywhere.
Talk with your local metal roofing expert to learn more about what you can do to decrease the amount of condensation forming on the underside of your metal roofing. It is a fixable problem that you shouldn't ignore.Share
