Here in North Central Florida, we know a thing or two about the beating nature can put on our roofs. Severe weather aside, blistering sun, large temperature swings, and even wildlife all work to damage our asphalt shingles.
Shingles are the most common residential roofing material. (That’s why we put together this complete guide to asphalt shingles). Today we’ll take a look at some of the warning signs that your shingles have been damaged and need replacing.
Shingles that have been hit by hailstones or debris often appear bruised. They appear darker than the shingles that surround them. Sometimes this darkening can even appear as a round, dented area.
Note: Not all discoloration is bruising. Learn when it’s serious and when it’s harmless in our guide to roof discoloration.
The impact that caused the bruising can loosen the shingle granule, weakening it and compromising its weather resistance. Replace any bruised shingles as soon as possible.
Exposure to extreme heat can cause shingles to blister. This looks like bubbled areas where granules are missing.
Blisters allow moisture to seep beneath the shingles and lead to leaks. Replace blistering shingles as soon as possible.
Cupped or Curled Shingles
Over time, shingles can deform. They can develop a curled, raised edge. Or they can take on a concave or cupped shape. These contorted shingles hold water instead of channeling it into your gutters.
The cupping or curling also increases the likelihood that water will seep under your shingles. Replace cupped or curled shingles as soon as possible.
Shingles expand and contract as the temperature fluctuates. This can cause cracks to form on the surface of the shingle.
Cracks compromise the weather resistance of the shingles and lead to water infiltration. Replace cracked shingles immediately.
Flaking occurs as your shingles age. As granules flake off older shingles, it often accumulates in the gutters and can look like very coarse, glittering black sand.
Flaking increases weathering and is a sign that your roof is nearing the end of its lifespan. If you see substantial flaking, schedule an inspection or call about a replacement immediately.
Mold or Plant Growth
Standing water, shade, and accumulated debris all lead to the growth of mold and moss. These growths can trap moisture in the shingles and weaken them.
Moss growth is especially damaging to shingles. Not only does it also trap moisture, but it can begin growing beneath your shingle and lift it away from the surface of your underlayment.
Remove any growth immediately by brushing or low-pressure washing.
