2.) Blistering or Peeling Paint

      When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation. The air in the attic needs to flow freely from the soffit to the ridge to reduce humidity. Make sure there is a vent in areas such as the kitchen or bathroom. Dryers should vent outside.

3.) Stains on ceiling or mold and mildew growth

     If you see stains or, even worse, mold growth inside your home, it may be caused by inadequate or faulty  underlayment that is allowing water to seep into the house. Inadequate ventilation could also be the culprit, which causes excessive moisture— conditions in which mold and mildew thrive.

4.)  Missing, Cracked or Curled Shingles

      If you see that your shingles are dry or practically break when touched, that means they have reached the end of their useful life and it’s time to invest in a new roof.

5.) Dark, "dirty looking" areas on your roof

      This could mean your roof has vegetation, fungus, mold, or algae growth, or that the shingles’ protective granules have been lost. This doesn’t mean you need to replace your roof, but these stains can reduce curb appeal. Cleaning the shingles is an option, but that could shorten their life.

1.) A Leak in the Attic

          After a strong storm or wind-driven rain, take a look in the attic for signs of leaking. Ice damming can also cause water to enter the house if you don’t have an adequate shingle underlayment or if the flashing  has deteriorated.


6.) Excessive Energy Cost

      A possible cause of higher cooling costs could be insufficient attic ventilation, requiring the 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. In both hot and cold weather, moisture in the attic can become trapped and condense on the rafters if it’s not insulated properly. This moisture can drip down onto the insulation and reduce its effectiveness, potentially increasing energy costs.
