Noticing algae or moss growth on your roof should prompt swift action. If you let these substances continue to grow, they could damage your roofing material and shorten the roof system’s lifespan. Cleaning them off prevents further damage, but you must be careful not to use abrasive methods that could harm your roof in the process.

Safe Cleaning Methods To Remove Algae and Moss From Your Roof
Your roof protects your home against severe storms and pest damage but is also vulnerable to certain cleaning products and methods. Avoid harsh techniques, such as power washing the roof, as this could damage the shingles.
Instead, certain algae, moss, and lichen treatment methods are generally considered safe for roofs:
- Soft washing: While a power washer may be too harsh for your roof, soft washing is a similar cleaning method that uses a gentler spray.
- Oxygen bleach: Bleach kills algae, but applying a full-strength solution could damage your shingles. Therefore, you’ll want to combine it with equal parts water before spraying it on the affected areas. Let the mixture sit for 15 to 20 minutes, then rinse it off with a hose.
- Vinegar and water: For mild algae and moss, a mixture of vinegar and water may do the trick. This biodegradable cleaner is also better for the environment than bleach.
If you want to remove algae and moss from your roof yourself, keep the following advice in mind to ensure your safety:
- Don’t stand on the roof unless you feel completely comfortable doing so. Instead, stand on a secure ladder when applying the cleaning products.
- Always have a family member or neighbor nearby when you are working on a ladder in case you lose your balance or need assistance.
- Avoid using a soft washer on your roof unless you have experience with this equipment. Using pressure washing equipment incorrectly can quickly result in injuries and serious damage to your property.
When To Hire a Professional
Polaris Roofing Systems does not offer roof cleaning services; however, it is important to hire a professional. While mild algae and moss may respond to DIY solutions, you’ll want to schedule a professional roof cleaning if:
- The algae or moss growth is severe, covering more than 25% of your roof.
- Your roof is too high or steep for you to reach it comfortably.
- You do not have experience working on the roof or using ladders.
- Your roof has other forms of damage, in which case you’ll want to hire roof maintenance professionals to repair these before you attempt mildew removal.
Ways To Prevent Moss and Algae Regrowth
After removing algae and moss from your roof, keep them from coming back by implementing the following prevention measures:
- Trim back any trees that block sunlight from reaching the roof. Moss and algae thrive in dark, moist environments.
- Clear debris from the roof regularly.
- Improve ventilation in your roof and attic to prevent moisture accumulation.
- Clean gutters at least once or twice a year to allow water to drain off the roof adequately.
- Ask your roofing professional about adding zinc or copper strips to the roof, which release particles that prevent moss growth.
- Schedule routine maintenance to check for signs of regrowth.
