3 Common Problems With An Asphalt Shingle Roof

Asphalt shingles are a popular roofing material since they are affordable, versatile, and easy to install. However, like other roofing materials, asphalt shingles have several drawbacks that you should know about. That way, you will know when to schedule repairs with professional roofers if signs of roof damage appear.

Check out three types of asphalt shingle roof failures you're likely to experience.

Granule Loss

Asphalt granules are comprised of crushed natural stone and minerals. The primary purpose of these granules is to protect your roof against the sun's harmful UV rays and extreme temperature fluctuations.

Naturally, an asphalt shingle roof experiences some granule loss due to prolonged exposure to external elements. However, granule loss indicates that your asphalt shingle roof is living on borrowed time. The result is clogged gutters or a leaky roof.

The major culprits for granule loss are extreme weather conditions and continuous physical damage. Extreme heat can also melt the asphalt and cause granule loss. If you notice the granules in your gutters or downspouts, a professional can help you determine the cause of this issue. 

Curling or Missing Shingles

Moisture tends to seep into poorly ventilated shingles and causes them to curl upwards. Once the moisture dries out or escapes, the dimensions of the shingles change such that they can't lie flat. 

Shingles also curl due to thermal shock, where temperatures change rapidly. For instance, if it begins to rain on a hot summer day, the roof cools down suddenly, which creates a curling effect on the shingles. Unfortunately, curling shingles not only ruin your roof's aesthetics but also make your home susceptible to leaks.

Missing shingles are also a typical asphalt shingle roof problem. This happens if:

  • A windstorm blows off the shingles
  • An object hits your roof and disengages the shingles
  • The sealing on the shingle's back breaks

Missing shingles expose your home to harsh external elements. So, perform regular roof inspections (especially after a windstorm passes) to check the condition of your shingles. 

Gloeocapsa Magma

Gloeocapsa Magma is a bacteria that comprises green-blue algae spores. The bacteria create a pigment that causes unsightly black streaks and stains on your roof.

Gloeocapsa Magma is common in hot and damp areas. This silent roof killer ruins your home's curb appeal significantly. Consequently, a prospective home buyer may not be willing to pay a reasonable price because the algae on the roof can seriously deteriorate the roofing material's condition.

Furthermore, the bacteria eat away the limestone on your shingles and weakens your roof over time. Weakened shingles break and fly away easily in strong winds. Your roof will likely need repairs more frequently. 

Regular roof maintenance and prompt repairs are crucial to extending the life of your asphalt shingle roof. Remember to only use reputable roofing services for roof repairs and installation.
