As winter transitions to spring, it’s fairly common for us to get calls from homeowners who believe they have a leak coming from their attic. In most cases, though, it’s not a hole in the roof causing the leak—it’s frozen condensation in the attic melting.
Here’s what happens: Over the winter, windows and doors are kept shut to keep out the cold. Moisture from cooking, taking showers, standing water and even plants works its way upward into your attic, where it condenses and freezes. Then, when the weather warms up, the frozen water melts and ends up dripping into your home.
It may not seem like there could be enough condensation created in a house to cause water to leak from the attic, but a family of four generates 30 lbs. of moisture in the air every day. The moisture in the air inside your home radiates upward into the attic, where it forms condensation on the roof joists and roof deck in your attic.
If your home made it through the fall with no leaking during rain storms, chances are your roof is fine and the dripping is coming from the frozen condensation in your attic starting to melt. Still, it’s a good idea to have your roof and attic inspected. Condensation can lead to mold growth on insulation, and the added weight of water-damaged insulation can even cause a ceiling to collapse. Of course, if a big rain comes and the leaking increases, there’s a good chance you have a leaky roof. Either way, call Infinity Roofing and we’ll take a look.
