Having a roof over twenty years old is a pretty good giveaway that you need a new roof, but younger roofs can have issues too. Here is a step-by-step approach to seeing if you need a new roof. But remember, if you have any questions or concerns be sure to call your local roofer to verify your situation.

First, take a good look at your roof from the ground and leave the dangerous ladder work to the professionals. This can be done by simply walking around your home with a pair of binoculars. Look for these key failures which may indicate a failing roof:

1.) Missing granules. Look for dark, smooth patches where the protective granular coating has worn off. This can be a sign of either hail damage or general wear-and-tear which happens over time. For hail damage, you may notice “spots” where hail has damaged panels, where general weathered panels will start to look patchy and smooth.

2.) Curled or buckling edges. Panels which appear to be warping need to be replaced as they may be letting in water and allowing energy to escape. This can be caused by general wear-and-tear, or by high winds.

3.) Moldy or green patches. Though many new asphalt shingles are coated to repel moisture and mold, both new and old panels still can rot and lead to water damage and energy loss.

Secondly, check inside your home for brown ceiling stains. If you notice brown spots appearing on your ceiling, you most likely have a failing roof.

Third, if you feel comfortable going up into you’re attic, scan the roof to check for soft spots and areas where water is leaking through. Shut off the lights to make sure you do not see any light coming through either which may indicate a flashing failure.

Last but not least, call your local roofer to verify damage, especially right after a storm. If signs of damage are found they can help you get your roof back into top shape and document any damage for insurance claims.
