Many homes in South Carolina have asphalt shingles on their roof. This is not surprising since they are affordable, safe, versatile, durable and available in a variety of styles. However, like all roofing materials, they are subject to wear and tear over time. Sometimes, they fail prematurely. If you have an asphalt shingles on your roof, it would be useful to know some of the problems you may experience during your roof’s lifespan. That way, you’ll know when it’s time to call in a Greenville roofing professional to deal with signs of damage.

Here Are Some Of The Things That Could Go Wrong With Your Shingles


If you notice some of your shingles curling, it is likely because of moisture. Moisture can get into shingles when they aren’t properly ventilated. When the shingles eventually dry out, their dimensions may change, affecting their ability to lie flat. If the problem is minor, you may be able to glue down the curling shingles. However, in severe cases, you’ll have to replace the roof.


Small blisters tend to develop in asphalt shingles as they get older. However, you may also notice these elevated areas in roofing materials that are quite new. This can be due to a manufacturer’s defect or poor roof ventilation.

Different colors of asphalt shingles for a roof replacement.

Raised Shingles

If your shingles weren’t properly installed, they may begin to lift, especially when exposed to strong winds. Shingles need to be installed with the correct number of fasteners in the right locations. Otherwise, you may notice a number of raised shingles even though your roof is not old. That’s one of the reasons why you need to hire roofers in Greenville, SC who are licensed and certified.

Granule Loss

The loss of granules usually indicates that your shingles have reached the end of their lifespan. However, sometimes, asphalt shingles show signs of premature deterioration. When this happens, you need to call in the professionals so they can identify the cause of the problem.

Premature Cracking

Cracks can also appear on the surface of shingles as a natural part of the aging process. However, sometimes they are due to high winds, deck movement or stress.

Thermal Tearing or Splitting

Extreme changes in temperature can cause asphalt shingles to split or crack completely. If you don’t notice this in time, the cracks may allow water to penetrate other layers of the roof.

Reasons Why Shingles Fail

We’ve already alluded to some of the reasons why you may develop problems with your asphalt shingles. Now, let’s look at them in a bit more detail.

  • Product defects – Asphalt shingles are not very expensive to manufacture. Still, some companies use the cheapest components possible. If your shingles were not properly manufactured, you can experience problems.
  • Inadequate ventilation – If moisture and heat collect in the attic under the shingles, the decking and baseboard may move excessively. Shingles can get damaged when nails loosen, surfaces swell, and air pockets develop.
  • Thermal shock – Temperature changes are most likely to irreparably damage older shingles. If a thunderstorm or cool rain drenches a roof after an extremely hot summer day, it can lead to cracking and granule loss. The older the shingles are, the less elasticity they will have to cope with the change. High winds can make things even worse.
  • Your shingles will fall into disrepair – If your roof is dirty and littered with leaves and branches. Roofs that are heavily shaded can age prematurely because of the growth of moss, algae, and lichen.
  • The Elements – Rain, blistering sun, hail, and high winds will all take a toll on your roof over time. The most adverse weather your home is exposed to, the more likely it is that your shingles will be affected.
