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:

Stains on interior ceilings and walls or mold and mildew growth:
Possible cause: Inadequate or faulty shingle underlayment allowing leakage or inadequate ventilation.

Decay of roof shingles, sheathing, and/or siding:

Dark, “dirty-looking” areas on your roof
Possible cause: Environmental pollutants; vegetation, fungus or algae; loss of granules due to age of shingles.

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.
