Warning Signs You May Need a Roof Replacement
How do you know if there are roof danger signals? Watch these videos to spot potential problems.
1 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.
2 Stains on interior ceilings and walls; mould or mildew growth.
If you see stains or, even worse, mould 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 mould and mildew thrive.
3 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.
4 Dark, “dirty-looking” areas on your roof.
This could mean your roof has vegetation, fungus, mould, 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. Fortunately, StainGuard® protection is available on many GAF Shingles, including Timberline® Cool Series Shingles, Timberline® Natural Shadow® Shingles, and Timberline® ArmorShield™ II Shingles. (StainGuard® protection is available only on shingles with StainGuard®-labeled packaging. See GAF Shingle & Accessory Ltd. Warranty for complete coverage and restrictions.)
5 Leaking roof
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.
|Did You Know?
|A way to prolong the life of your shingles is to install proper ventilation. Asphalt shingles should never be installed on flat roofs as it does not have a slope for water to flow away.
|Clean up tree debris! A little leaf or a few pine needles are fine, but if they collect and are deep enough to hold moisture, they need to be taken off the roof. Anything that traps moisture will cause mildew to form, block gutters, or cause extra weight on the roof. A rake or air blower can be used to clear the roof, but take care not to damage the shingles.
* The word “Lifetime” means as long as the original individual owner of a single family detached residence (or the second owner in certain circumstances) owns the property where the shingles are installed. For owners/structures (e.g., a church) not meeting above criteria, Lifetime coverage is not applicable. See limited warranty for complete coverage and restrictions. Installer certification is only for installations covered by GAF system warranties. Maximum wind coverage requires special installation. See limited warranty for complete coverage and restrictions.
