Suspect Moisture Infiltration In Your Attic? What You Can Do

April 10, 2012   ·   By   ·   No Comments   ·   Posted in Service & Maintenance

Attics and moisture are like oil and water; they do not mix, nor are they supposed to. Attic moisture can be a contributor to higher energy costs and roof damage. The only way to tackle this problem is to understand what to look for and what to do if you find moisture in your attic.

Moisture enters attics in several ways:

  • Roof leaks or incorrectly installed chimney flashing and other roof penetrations.
  • Water vapor accumulation from indoors or outdoors because of lack of proper ventilation, or as a result of moist air from bathrooms or kitchens being exhausted into the attic.
  • Ice dams in roof gutters allowing water to leach under shingles into the house (not a problem in the Phoenix area).

Signs of Moisture

You can schedule a home performance contractor to examine your attic or you can examine it yourself. Here’s what to look for:

  • Warped or rotting wood soffit panels or the horizontal boards underneath.
  • Bubbling paint at the soffit or underlying horizontal boards.
  • Tattered or distorted shingles on the roof’s edges.
  • Damp attic insulation, especially around the eaves.
  • Mildew or mold growth on attic surfaces.
  • Rotting or warped wood in the attic.

What to Do

Inspect. Roofs need to be properly constructed from the beginning to prevent moisture penetration. A layer of waterproofing will provide extra protection by stopping water penetration, filling spaces and inhibiting leaks.

Insulate. Without strong insulation, heat can build up in the summer, making it more difficult to cool the rooms below.

Ventilate. Inadequate ventilation gives moisture a chance to accumulate in your attic, leading to rotting wood, mold buildup and insulation damage. Even if moisture damage is addressed, the process will be ineffective as the root of the problem has yet to be solved.

Seal attic gaps or leaks. Your home needs to have enough sealing between the top floor and attic space to prevent warm, humid air from bathrooms, kitchens, and dryers from entering. Leaks and gaps are usually found around ductwork, plumbing, wires and around attic entryways.
