5 Reasons Why Your Roof is Discolored

Have you noticed a change in the color of your roof? If your roof is discolored, it could be due to a few different reasons. Here are the top three reasons why your roof may be discolored:




1. Algae growth


Algae can cause black streaks or stains on your roof. This growth is usually caused by moisture and warm temperatures. While algae growth is not harmful to your roof, it can be unsightly. Also, if left untreated, algae can lead to more serious roof problems such as leaks.

2. Moss growth


Like algae, moss can also cause black streaks or stains on your roof. Moss prefers shady, damp areas to grow. If your roof doesn't get much sunlight or if it has a lot of tree coverage, moss may be more likely to grow. Moss can also hold moisture against your roof, which can lead to leaks and other damage.

3. Weathering


Over time, the sun, wind, and rain can wear down your roof's protective coating. This exposure can cause your roof to fade in color or become discolored. In some cases, weathering can also lead to leaks and other damage.

4. Pollution


Air pollution can also cause your roof to become discolored. Soot from cars or factories can settle on your roof and cause a black or gray stain. So, if you live in a city or near a busy highway, your roof may be more susceptible to pollution stains.

5. Dirt and debris


If your roof is not cleaned regularly, dirt and debris can build up and cause discoloration. Leaves, twigs, and other organic matter can hold moisture against your roof and lead to stains. In addition, bird droppings, tree sap, and other materials can also cause staining. Also, if you have a fireplace, the soot can discolor your roof.

If you notice any of these problems, it's important to have your roof inspected by a professional. A roofing contractor can determine the cause of the discoloration and recommend the best course of action. Contact a local roofing company today for more information.
