Danger Signals

There are many warning danger signs that the integrity of your roof may be in question. Such signs such as leakage, blistering, stains, exterior decay and cracks are indicators that you may need roof repair or maintenance.
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.
