Five Subtle Signs (And One Obvious One) That You Have A Roof Leak
Sometimes a roof leak is impossible to miss, like when you spot a discarded screw on the membrane next to a puncture. However, more often, leaks manifest in subtler ways. Keep an eye (and nose) out for these warning signs:
- Unexpectedly High Energy Bills
Waterlogged insulation loses its Rvalue, forcing your HVAC system to work harder and driving up utility costs. If your summer energy bills spike without explanation, a compromised roof could be the culprit.
- Soft Spots Underfoot
When walking the roof, pay attention to any areas that feel spongy or give underfoot. Soft spots often indicate saturated insulation and an entry point for water.
- Musty Odors Indoors
Damp insulation and trapped moisture create the perfect environment for mold. A persistent musty smell inside your building is a red flag for water intrusion and microbial growth.
- Flaking or Peeling Paint
Water seeping behind interior walls can loosen paint, causing it to blister, flake, or discolor. While paint can peel for many reasons, paired with other signs, it often points back to a leak.
- Unusual Exterior Moss or Mildew
Moss and mildew thrive in damp, shaded conditions, but abnormal growth on one side of your building can signal chronic moisture from the roof or drainage damage.
- Visible Water Accumulation (the Obvious Sign)
Puddles on floors or water dripping from ceilings confirm a leak, but not necessarily above where you see it. Water can travel along beams and conduits before it appears, making professional diagnosis essential.
Even when signs seem clear, pinpointing the source of a roof leak can be a challenging task.
