Roofing Danger Signs

Leakage in attic after wind-driven rain
Possible cause: Leaky or inadequate shingle underlayment or deteriorated flashing.

Leakage in attic after ice build-up (Ice Dams)
Possible cause: Inadequate shingle underlayment allows water from ice dams to leak into attic. Other causes include inadequate attic insulation that allows heat to escape through the roof and melt the snow on the roof. Good insulation will keep the heat in your house and away from the attic space and roof. Another potential cause of ice dams is air leaks around chimneys, vents, plumbing and wiring. Leaky ductwork can allow warm air escape toward the roof.

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.

Decay of roof shingles, 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.
