5 Causes of Shingle Deterioration


Your roof is the first defense against outside elements, be it rain, snow or wind. As a homeowner in El Paso, you know well that our rain and wind storms can go from bad to worse within minutes and while we are fortunate to live in a city with mild winters, when it does snow, it can cause damage to your roof. Extreme weather conditions are what essentially reak the most havoc on our roofs. However, there are also everyday elements that also cause damage to the roof such as exposure to the sun and normal wear and tear over time. No roof is protected against weather damage.

With a large majority of shingle roof homes here in the Sun City, we thought we’d focus on an area of the roof can help avoid extreme damage to both your roof and the inside of your home. And that is worn-out or missing shingles. The main contributor of missing or deteriorated shingles is the weather. Each condition brings different challenges. Here’s what they include:

1- Sun

A good roof coating will help fight the sun’s UV rays. However, over time the coating will also be eaten up by the sun. Basically, it’s inevitable to have your roof be fully protected from the sun. With months or years of exposure to the sun, shingles are bound to break down from the strong IR radiation and UV light.


We know windy weather around here. When the wind reaches extreme speeds it has the ability to significantly impact your roof. In many cases, it can lift shingles and blow them off completely. High winds also lead to extreme damage on the entire roof structure because it blows debris and other items onto the roof.

3-Hail or severe rainstorms

Hails removes mineral granules from the roof that are intended to protect the roof from UV rays and other water-shedding capabilities. A loss of mineral granules results in your roof being directly impacted by other elements. If your roof isn’t serviced following a hail storm or even an extreme rainstorm, you risk the possibility of structural damage.     

4- Tree Limbs

If your trees begin to touch your roof’s home, they’re too long. From the leaves clogging up the gutters to the limbs puncturing your roof, you can be dealing with a whole host of issues. Overgrown trees also affect your roof’s shingles because their direct impact with the shingles tends to be negative. It will result in rotting, complete removal, and other damage such as water seeping into the roof.

5- Lichen

Algae and moss will rot and destroy your roof over time. They’re also one of the causes of discoloration. While lichen does not trap as much water as moss, it does penetrate into the shingles of the roof, which results in a great deal of damage. Shingles need to be protected against algae and other fungi.

Don’t Wait to Replace Curling or Missing Shingles

Generally, asphalt shingles can last 20 to 30 years but their lifespan has a lot to do with the weather, regular maintenance, the quality of their installation, and the quality of their material. One of the best ways to keep your roof’s shingles in good condition is to have them inspected regularly. As a homeowner, you should have your roof inspected AT LEAST ONCE a year. If your roof is reaching 15 years, it especially requires a yearly routine maintenance check.

It’s often impossible to see curling or missing shingles from the ground. And it’s not safe for you to get on the roof and look for them. The best thing to do is to call in a professional roofer. Through a professional inspection, a professional roofer will be able to thoroughly inspect the roof and uncover hidden signs of damage. They will also be able to give you an update of your roof’s overall condition. If repairs need to be made, your roofer will also inform you so that they can be handled in a timely manner.
