During a rain storm your roof collects an amazing amount of water. This occurs when moisture filled air from the outside gets into the crawl space and cools then condenses at dew point. When it comes to crawl space leaks and flooding gutters and downspouts may rank at the top of the list. The moisture in crawl space under house usually comes from three main sources including bulk water outdoor air coming in through the crawl space vents and moisture from the ground.

A damp crawl space could lead to a variety of health and safety problems in your home. Patching material may not adhere properly if the roof area is damp. During extreme cold temperatures frost can build up on the underside of the roof sheeting attic roof. When this happens water can seep through porous walls and end up in the crawl space.

If the gutters are not cleaned regularly the water has nowhere to go. Excessive indoor humidity can cause blistering and peeling paint warping and rotting wood as well as the formation of mildew mold. These could include mold and mildew growth as well as rotted floor joists and support beams. Once the outdoor temperature rises that frost melts and can mimic a leak.

Roof leaks can occur when the flashing around a vent pipe or chimney separates from the roof and creates a gap. Water may collect and sit for days until it evaporates. Furthermore a damp crawl space will welcome unwanted pests such as termites snakes rats spiders and other vermin that seek out damp dark spaces.
