How to Find a Roof Leak 

If your house is experiencing mold in the ceiling or other places you may be wondering “can roof leaks cause mold?”  

If so, the answer to this question is yes. Roof leaks are a possible cause of mold. Mold grows within trapped areas where moisture can’t escape. When the roof leaks, air cannot reach the moisture to dry the area. As a result, moldy bacteria forms in the damp area. 

If you suspect the mold is a result of a roof leak, make sure to carefully inspect your roof and rule out these alternative locations for water leaks.  

How to Check for a Roof Leak  

To check for a roof leak, make sure to look for the following: 

  • Stains on the walls and ceilings. 

  • Musty smells or an odor that smells like mold. 

  • Missing, water-damaged or damaged shingles.   

  • Waterlogged exterior siding. 

  • Rust that’s apparent on metal roofs.    

Before you rule out the leak isn’t coming from the roof, test it out. Hose down the roof to test it with more water. Have one person wait inside, while you spray the roof with a garden hose outside one part at a time. Make sure to saturate each section with plenty of water and have the person inside call you when water starts to drip.  

How to Check for an Interior Water Leak  

If you don’t see any indication of a roof leak, it’s possible that you are experiencing an interior water leak. To check, make sure to do the following: 

  • Confirm the HVAC and AC are working properly  

  • Inspect all rooms with water pipes (kitchen, bathroom, laundry room etc...)  

How to Thoroughly Examine Your Attic 

Check for any signs of leak in your attic but be careful when you do this. Bring a flashlight for any dark areas. Look for any mold, water stains or musty smells around the rafters and roof sheathing.
