Signs of wear become apparent as a roofing system ages. It's likely time to schedule an inspection if there are indications of water damage, such as discolored materials, missing shingles, and granule clumps in the gutter. Here’s how to know if the surface has moisture damage.

How to Spot Water Damage in a Roofing System

1. Blistering & Cracking Shingles

Constant exposure to the sun’s UV rays and harsh elements will cause the shingles to lose their granules and structural integrity, becoming brittle and cracking or warping. Cracked and blistered shingles encourage moisture intrusion by providing pathways for rainwater to trickle through. The moisture will gradually weaken the structural foundation of the roof, so have a professional find and fix the leak's source immediately.

2. Granules in the Gutter

Large clumps of asphalt granules in the downspouts or gutter troughs mean the shingles need to be replaced. The shingles shed this material over time with wear, and thin shingles can't effectively deter moisture. Instead, the material will absorb and retain water.

3. Missing Shingles

Inclement weather can cause shingles to come off the roof. If you notice missing pieces from the ground, have a roofing contractor inspect the opening to determine if it caused any water intrusion and damage. Even if you can’t see missing shingles, schedule an inspection after a heavy storm so that a professional can make any necessary repairs.

4. Water Spots

Water spots on interior walls signal damage to the step flashing—this is the material that covers the area where the roof and wall meet. The step flashing rusts or loosens with age, enabling rain water to leak and leave unpleasant stains. Water spots can also form on the ceiling, and this indicates several potential issues, including loose or damaged shingles.
