If you’re like many people, you only pay attention to your roof when there’s an obvious problem. Modern roof technology has extended the life of the average roof, but there are tell-tale hints that you may need to replace yours now. Roofing contractors will tell you that a twice-a-year inspection can help you spot potential problems before they result in major damage. Here are ways to tell if your roof has passed its prime and needs a replacement.

What to Look For On the Inside

The time to wonder about your roof is not when you see water marks on your ceiling; by the time moisture makes it that far, there could be serious structural damage. Start your inspection in the attic area. You’re looking for signs of sunlight showing through the substructure, sagging or warped areas and dark spots that indicate moisture, mold or mildew.

What to Look For On the Outside

After you’re done a thorough inspection of the underside of your roof, it’s time to take a closer look at the surface. Start by looking at your roof on all sides from the ground, checking for dark streaks where algae or mildew are forming and overall patterns of wear; then it’s time to climb up and inspect your shingles. If you’re afraid of heights, this part can always be done by professional roof contractors.

Climb up top and walk the roof to examine the entire surface area for missing or cracked shingles, bald spots, dips and sags. You should also check any flashing around vents, skylights and chimneys for loose material and fittings. Next, walk the perimeter to make sure that your gutters are firmly attached and free of debris; large amounts of roof granules filling the gutters are another sign of wear.

The Importance of Repairs or Replacement

The average roof, when properly installed by your roofing contractors, will last between 15 and 25 years, depending on the type of material. Any signs of a major issue in a roof that’s less than 15 years old warrant an immediate call for roof repairs. However, if your roof is nearing the minimum life expectancy and/or you’re getting ready to put your home on the market, it may be time to invest in a new roof.
