How Do I Know if a Water Leak Is From My Roof, Plumbing, or HVAC System?

Determining the source of a water leak isn’t always obvious. Water often travels before it becomes visible, making leaks difficult to trace without experience.

Signs the Leak May Be From the Roof

• Water stains after heavy rain

• Drips near ceilings or exterior walls

• Damage that worsens during storms

Signs the Leak May Be Plumbing-Related

• Water appears even in dry weather

• Damp areas near bathrooms, kitchens, or laundry rooms

• Sudden increases in water usage

Signs the Leak May Be From HVAC or AC Systems

• Water near air handlers or vents

• Ceiling stains below AC units

• Musty odors during warm months

Why Professional Assessment Matters

Because water can travel through framing and insulation, professional moisture detection is often the only reliable way to identify the true source and prevent repeat damage.

The Bottom Line

If you’re unsure where a leak is coming from, a professional evaluation helps stop guesswork, prevent further damage, and ensure proper drying.
