Do Not Pressure Wash Your Roof

Fall is here, and we want to talk about a common issue: moss and algae on your roof.

These little organisms love the cool, damp fall weather and can cause roof damage. But don’t worry! We’ll show you how to stop them and explain why you should never use a pressure washer on your roof.

Moss and algae find your roof really cozy in the fall. They grow in the cool and damp conditions brought by rain and lower temperatures. If not stopped, they can damage your roof and lead to expensive fixes.

Prevent Moss and Algae Growth:

  • Zinc or Copper Strips: The shingles we install at Beemer KangaRoof have higher copper content than most.  They actually wash the roof every time it rains. When it rains, water flows over these strips, carrying tiny bits that keep moss and algae away.
  • Regular Roof Cleaning: The key to stopping moss and algae is to keep your roof clean. Removing leaves, debris, and other stuff will make it hard for moss and algae to thrive.


How to Clean Your Roof the Right Way

  • Use a Soft Brush: Use a soft brush or broom to gently scrub away debris, moss, and algae. It’s safe for your shingles.
  • Roof Cleaning Solution: Some special roof cleaning solutions break down moss and algae. Follow the instructions and make sure it’s safe for your roof.


How to Clean Your Roof the WRONG Way

Some think a pressure washer is the way to go, but for your roof, it’s a bad idea. Here’s why:

  • Damage: Pressure washing can harm your shingles. The strong spray can remove the tiny granules on them, and then your roof is going to leak in no time.
  • Spreading Trouble: Oddly enough, pressure washing can spread moss and algae to other parts of your roof, making things worse. Every mowed over one pile of fire ants and the next day you have 3 piles of fire ants? Same concept. 


By following these steps and cleaning your roof properly, you can keep moss and algae from causing problems. Your roof takes care of you, so make sure to take care of it! And if you ever need help or have questions, Beemer KangaRoof is here for you.
