What is Growing on My Roof?

One of the most common questions we hear from homeowners is: “What exactly is that
stuff growing on my roof?” For many, the answer to “What is growing on my roof?” includes organisms that can eat away at your shingles. Roof discoloration and buildup often are more than just dirt. They can be living organisms that affect roof durability. This can shorten the
life of your roof. Understanding what’s up there is the first step toward protecting your
home and keeping it looking its best. Calling your local roof cleaning service will help get rid of the mess!

The Usual Suspects on Your Roof

If you’ve noticed black streaks, green patches, or fuzzy growth on your roof, you might wonder: “What is growing on my roof?” It could
indicate you have unwanted organisms on your roof. Here are some of the most
common culprits:

 

1. 1. Algae – Black streaks are typically a form of algae. It feeds on the limestone in
      shingles and holds onto moisture, which can weaken your roof over time.

1. 1. Moss – Moss thrives in damp, shaded areas. It grows thick and spongy, lifting
      shingles and trapping water underneath. That trapped moisture can lead to rot
      and leaks.

1. 1. Lichens – A combination of algae and fungus, lichens form growth that bonds
      tightly to surfaces.

1. 1. Mold and Mildew – While more common on siding and decks, mold and mildew
      can also creep onto roofs, especially in humid climates.

1. 1. Pollen, Leaves, and Debris – Even non-living materials like pine needles,
      pollen, and leaves can build up. They hold moisture and create the perfect
      breeding ground for organic growth.
