Leakage in Attic After Wind-Driven Rain

Possible cause: Leaky or inadequate shingle underlayment or deteriorated flashing.

Leakage in Attic After Ice Build-Up

Possible cause: Inadequate shingle underlayment allows water from ice dams to leak into attic.


Blistering and/or peeling of
interior and/or exterior paint

Possible cause: Excessive temperature or high humidity due to poor attic ventilation.

Stains on Interior Ceilings and Walls
or Mold and Mildew Growth

Possible cause: Inadequate or faulty shingle underlayment allowing leakage or inadequate ventilation.


Exterior Decay, Sheathing, and/or Siding

Possible cause: Poor attic ventilation.

Missing, Cracked or Curled Shingles

Possible cause: Shingles have reached the end
of their useful life.


Dark, "Dirty-Looking" Areas On Your Roof

Possible cause: Environmental pollutants; vegetation, fungus or algae; loss of granules due to age of shingles

Excessive Energy Costs

Possible cause:
Insufficient attic ventilation causes heating/cooling system to run excessively.

In warm weather, inadequate ventilation will trap
hot air in the attic, causing air conditioning systems
to work harder, or leaving your home's interior hotter and less comfortable.

Attic Ventilation: In both hot and cold weather, insufficient attic ventilation may cause moisture in the attic to become trapped and condense on the rafters. This condensed moisture can drip down onto the insulation and reduce its effectiveness. Excessive energy costs can result.
