When Do I Need a New Roof?

Here are some of the tell-tale signs that it is time to call Grennan Construction to talk about a new roof:

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

Leakage in attic after ice build-up
Possible causes: Inadequate shingle underlayment or inadequate attic ventilation

Blistering and/or peeling of interior and/or exterior paint
Possible causes: Excessive temperature or high humidity due to inadequate attic ventilation

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

Decay of roof shingles, sheathing, and/or siding
Possible cause: Inadequate 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 causes: Environmental pollutants; vegetation, fungus or algae; loss of granules due to age of shingles

Excessive energy costs
Possible cause: Insufficient attic ventilation
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. 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.
