If you have a sneaking suspicion that your home's asphalt shingle roof is getting old and might need to be replaced soon, then you need to know the six signs to watch for.
Below is a list of these six signs and a short description of each problem to help you inspect your home's roof for damage:
Sign #1: Curled or Buckled Shingles
The asphalt shingles on your home should always be laying flat. If you see shingles that are curling up at their edges or that have buckled up in the center, then these are two of the major signs of a roof that is worn and needs replacement. The curled or buckled shingles will allow stormwater to run underneath them and this will quickly ruin the underlayment below the roof.
Sign #2: Shingles that are Missing
If your roof's shingles blow off each time there is a big storm, then this is a sign that the shingles have become brittle from sun exposure and need to be replaced.
Sign #3: Shingle Granules or Nails Shedding Off of Roof
When an asphalt roof ages, it sheds some of its asphalt granule particles down through the rain gutters. Additionally, an aged roof will also pop out roofing nails and shed those down with rainwater as well. If you find asphalt granules or roofing nails under your rain gutter system's downspouts, then your roof is getting old and nearing the need for a replacement.
Sign #4: Dark Streaks or Stains on the Roof
If you see dark stains or streaks on your roof, then these are caused by the growth of algae, mold, mildew, or moss. Since biological contaminates require constant access to water to grow, seeing these things growing on your roof always signals a problem with the roof's drainage.
Sign #5: Your Roof has Areas that Sag
When you look up at your home's roof from the ground, it should always look flat. If you see areas that are sagging or bowing, then there is water damage to the roofing materials. This is a common sign of a roof with a problem.
Sign #6: All Your Neighbors are Getting New Roofs Installed
Finally, if you live in a subdivision and all of your neighbors have been replacing their roofs, then it is likely that your roof will need replacement soon as well. Developers use the same roofing materials on all of their homes in a new development and when they start to wear out on one home, they are also wearing out on all of the others.
