4 Common Signs of a Roof Leak You Should Never Overlook

A roof leak can start small but quickly become a major problem if left unaddressed. Water intrusion has the potential to damage your home’s structure, ruin insulation, stain ceilings, and encourage mold growth. Unfortunately, roof leaks aren’t always obvious, and many homeowners only notice them once the damage is extensive. At Orlando’s Pro Roofing, we provide expert roof leak detection and repair in the greater Arlington, WA area. Here are four common signs of roof leaks.
Water Stains on Ceilings or Walls
One of the most common indications of a roof leak is the appearance of discolored patches on ceilings or upper walls. These stains are often brown, yellow, or rusty in color and can grow over time if the leak persists. Even small water spots mean moisture is getting into places it shouldn’t, and it’s essential to have the source located and repaired before the problem spreads.
Dripping Water or Moisture in the Attic
If you notice damp insulation, wet wood, or actual dripping water in your attic after a rainstorm, your roof is likely compromised. This is often where leaks first show up, as water seeps past damaged shingles, flashing, or underlayment and collects in the space directly beneath the roof. Regular attic checks during wet weather can help you catch a leak early before it reaches your living spaces.
Damaged or Missing Shingles
While missing shingles alone aren’t proof of an active leak, they are a clear sign that your roof’s protective barrier has been weakened. Cracked, curled, or broken shingles can allow water to penetrate beneath the surface, especially during heavy rain or wind. If you see significant shingle damage after a storm, it’s wise to have your roof inspected for potential leaks.
Mold or Mildew Growth Indoors
Excess moisture from a roof leak can create the perfect environment for mold and mildew to thrive. If you detect a musty odor or notice fuzzy or discolored patches on walls, ceilings, or around vents, the issue may be water entering from above. Mold spreads quickly and poses health risks, so it’s important to address the source of the moisture as soon as possible.
