Why Are My Shingles Discolored?


As a homeowner, noticing discoloration on your shingles can be alarming. After all, your roof is supposed to protect your home and keep it looking great, so any signs of wear and tear can be concerning. But what causes shingles to become discolored, and is it a cause for alarm?



Mold and Mildew

One of the most common causes of shingle discoloration is mold and mildew growth. This is particularly common in areas with a lot of moisture, such as humid climates or where it rains frequently. Mold and mildew can grow on shingles that are not adequately ventilated, damaged, or worn.

Mold and mildew can spread quickly, and if left untreated, they can cause severe damage to your roof. In addition to discoloration, you may also notice a musty odor or the presence of moss or algae on your roof. It is important to note that you should never power-wash asphalt shingles. A soft wash can help but should be administered by a professional. 



Sun Damage

Another common cause of shingle discoloration is sun damage. Over time, exposure to the sun's UV rays can cause shingles to fade and become discolored. This is particularly common in areas with a lot of direct sunlight, such as in the southern United States. If you notice that your shingles are becoming discolored due to sun damage, you can do a few things to prevent further damage. First, consider installing a reflective roof coating to help protect your shingles from the sun's rays. Consider installing a ventilation system to help keep your roof cool and prevent further damage.



Chemical Damage

Another less common cause of shingle discoloration is chemical damage. This can occur when shingles come into contact with chemicals such as bleach or other cleaning products. Chemical damage can cause shingles to become discolored or deteriorate over time.

If you suspect that chemicals have damaged your shingles, taking action immediately is essential. The longer the chemicals are left on your shingles, the more damage they can cause. Avoid harsh cleaning products on your roof to prevent chemical damage, and be careful when using chemicals around your home.



Age

Finally, it's important to remember that shingles will become discolored over time. As shingles age, they may become faded or discolored due to exposure to the elements. This is particularly true for shingles exposed to extreme weather conditions, such as heavy rain or snow.

If you notice that your shingles are becoming discolored due to age, you cannot do much to prevent it.


However, you can ensure that your roof is maintained correctly and that any damage is repaired quickly.


In conclusion, shingle discoloration can be caused by various factors, including mold and mildew growth, sun damage, chemical damage, and age. If you notice discoloration on your shingles, immediately preventing further damage is essential. Keeping your roof clean and dry, installing a reflective roof coating, and avoiding harsh chemicals can help ensure your shingles look great for years.
