What is Roof Condensation? Roof condensation is moisture that occurs on the undersides of buildings s roof, or even on underground structures located below the attic or crawlspace. It is much like the condensation you may notice appear on wet glass on a very hot, sunny day. The source of the moisture may be rain or water leaking from a roof or windows, roof vents, plumbing leaks, or faulty drywall.
If you have noticed moist patches on your ceiling, walls, or the floor of your home, roof condensation may be the culprit. While roof condensation doesn’t normally threaten a roof repair job, it can be a serious threat to the health and safety of your family. Even if a leak or other problem is not present, roof condensation can still form. And, unfortunately, leaks and damage from roof condensation can often be hidden by the roofing materials used to construct the home.
How are Roof Leaks formed? – One of the most common causes of roof condensation is a roof leak. Roof leaks are a serious threat to your home and family because they allow moisture to get into your attic space and surrounding spaces (such as crawlspace and basement). Over time, roof condensation can cause the growth of mold and mildew, giving your home a bad odor, mildewy feeling, and unhealthy moisture. A roof leak can also allow untreated water vapor to evaporate into the atmosphere, eventually causing roof damages even when there are no leaks.
There are many roof condensation solutions. One way to prevent roof condensation is to use a special roof insulation product. The right roof insulation product can reduce the amount of heat loss through the roof. The extra space is created to retain heat and cold air. This method of roof insulation makes it necessary to have an attic ventilation system (also called roof vents) that exhausts roof condensation away from the home.
Another way to prevent roof condensation is to remove existing roof condensation on your roof. This can be accomplished by a thorough cleaning using a high-pressure jet of water. If this technique does not work, you will need to hire a professional roofing contractor to do this for you. And, roof condensation can become a problem in homes with limited roof ventilation. In these homes, excess humidity can build up and cause water damage to wood and metal roofing materials over time.
You may also need to consider the installation of new roof vents. The venting system must include new screens or baffles to reduce the entry of moisture into the attic space. Moisture can weaken roofing materials, especially shingles, causing them to sag and allowing roof condensation and mold to form. As a result, it becomes necessary to check and replace shingles regularly.
The third way to deal with roof condensation problems is to block the escape of moisture and cool air from your attic space. The most common way to accomplish this is by installing a vapor barrier. To keep your attic temperatures warm enough to prevent roof condensation, you must have a sufficiently high roof dome clearance.
One type of roof condensation problem that is not so easy to detect is that of chemical leaks. These can take the form of pooling water under the roof structure causing dampness and damage to the roof. But, in addition to this water, chemicals can drip onto the roof and damage the insulated materials below. This problem is difficult to detect unless there is an obvious water leak such as discolored seepage from a roof vent.
