Key Danger Signs of a Failing Roof - By GAF

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 (the aluminum or steel used over roof joints, like chimneys and pipes) has deteriorated.

2. Blistering or peeling interior or exterior 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 interior ceilings and walls; mold or mildew growth.

If you see stains or, even worse, mold growth inside your home, it may be caused by inadequate or faulty shingle 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. Exterior decay, sheathing, and/or siding.

Poor attic ventilation is again a possible cause, but any condition that results in excess moisture can contribute to decay. One way to combat the problem is to put a vapor barrier between the insulation and the inside of the house, which can reduce the amount of moisture that goes into a wall and help the moisture escape from the wall.

5. 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.

6. 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.

7. Excessive energy costs.

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.

It's All About The Look!

Are you fixing up your home for resale or planning to stay in it for 30 years? This may influence your decision on colors and dimensions. Do you have a north-facing roof or does a tree overhang your roof? This may influence your decision to choose a zinc & copper additive to combat algae growth that often leaves dark streaks on the roof.

A Few Important reasons to consider a new roof from Excel Roofing, Bel Air MAryland

Safety: The longer you wait to replace that old, dilapidated roof, the more dangerous the situation can become. An old roof in some cases may collapse or cause part of the home to become unstable.

New Technology: Because roofs last such a long time, the technology of a new roof is no doubt several generations ahead of a roof that was put on in the early 1960s.

New Look: The new roof can have windows or a skylight installed, which will bring more light into the attic or into the house in general.

Stress-Reduction: No one wants the continued worry of a roof’s ability to withstand the elements and hardships of Mother Nature. Knowing your roof is solid, possibly warrantied for many years, and will keep your property dry and warm inside presents a wonderful peace-of-mind.
