Stains, bulges, mold growth, or drips on your ceiling typically indicate a roof leak. Cathedral ceilings and a variety of roof types can lack attics. You’ll need to know a few tricks of the trade to learn how to find a roof leak with no attic. Once you narrow down where the roof has failed, you can locate the precise place that requires a roof repair.
How to Find a Roof Leak with No Attic Directions
- Find all of the water stains on the ceiling.
- Look specifically for a stain that is higher up the cathedral ceiling than the other stains.
- If you see a small stain in a high location, ask yourself if it is upslope from larger lower stains.
- If a small stain is higher up the slope than a big stain, then that should be where water is penetrating.
- The water gets in and then runs down inside the ceiling until pooling and forming a larger stain.
- Now that you know the general area of the leak, carefully get up on the roof.
- Mount an extension ladder securely at the edge of the roof.
- Wear nonskid rubber-soled shoes when climbing on the roof.
- Approach the area of the suspected leak.
- Inspect the flashing on any nearby vents or chimneys for damage.
- Look at the shingles to see if any are loose or if moss is growing over them.
- Take a pry bar and gently lift up shingles to look at the roof deck.
- The leak will be evident if you see broken tar paper and rotting wood.
- If you can’t find obvious damage, pull a garden hose up on the roof.
- Soak the shingles in small locations and ask someone in the house to watch for leaks.
- Be methodical as you wet small areas of the roof until you find the leak.
