What Are the Dangers of a Leaky Roof?

Cause and Size

• The leak could have one of several causes ranging from damaged shingles to improperly installed flashing. Whatever the cause, the leaky roof allows water into your home instead of providing protection from the elements. A small leak causes fewer problems than a large leak, but any leak size causes water damage to the home. The longer it takes for you to repair the leak, the more extensive the damage becomes.

Initial Dangers

• Initial dangers of a leaky roof include water damage to items stored in the attic. If the home doesn't have an attic or if the leak is large, then the leak will damage the home’s ceiling. Affected ceiling paint will darken and ceiling plaster may bubble and expand. The leaking water also will damage paint and plaster on nearby walls. If enough water comes down through the ceiling, you could see damage on ceiling-mounted lights and fans.

Long-Term Dangers

• A leaky roof has several long-term dangers. Wet wooden supports that hold up the roof can sprout mold and rot. Over time, they will weaken, impacting the home's structural integrity. The water can encourage mold growth in other parts of the house. That can damage walls and furnishings and also can be a health threat. Mold can trigger reactions including skin inflammation and trouble breathing. Extensive mold infestation can be difficult and costly to clean up.

Considerations

• Fixing a leaky roof as soon as you know it is a problem helps to deter its dangers to your home and family. Move everything you can out of the way of the leak. Dry everything that gets wet, including walls and support beams, as quickly as possible, and use fans if necessary. Placing tarps and plastic on the exterior of your roof will help to prevent rain from leaking into the home, but a permanent solution is necessary to protect your house. If you are not able to fix the roof yourself, contact a trained professional so the job is done correctly.
