Living in a region with warm, humid summers can lead to unsightly and potentially damaging growths on your roof, such as moss and algae. These not only affect the appearance of your home but can also cause structural issues over time. At G. Fedale Roofing and Siding, we’re committed to guiding you through the process of identifying and removing these common roofing adversaries and preventing roof damage.
How to Identify Moss, Algae, and Lichens on Your Roof
- Algae: Often appears as dark streaks on asphalt shingles. Unlike moss, algae lies flat against the roof’s surface and can spread across large areas, mainly due to its ability to thrive in damp conditions with minimal sunlight.
- Moss: This green, fuzzy growth prefers cool, damp environments and typically appears on parts of the roof that receive less sunlight, like the north slope. Moss can lift shingles and retain moisture, which can damage your roof’s structure.
- Lichens: A composite organism arising from algae and fungi living together, lichens form a crust-like or leafy growth on roof shingles. They are tough to remove and can etch into the asphalt shingle surfaces, causing damage over time.
Safe Roof Moss and Algae Removal Methods
While it’s advisable to seek professional help for roof maintenance, there are safe methods for those who prefer the DIY approach, which include:
- Eco-Friendly Products: Products like “Spray and Forget” or “Wet and Forget” can be applied using a hose-end sprayer. These require several months to work but are safe for your roof and surrounding plants.
- Bleach Solution: Mix 1 part water with 1 part oxygen bleach (add trisodium phosphate for tougher jobs). Apply with a spray pump, let sit for 30 minutes, then rinse with low pressure. This method is quicker but must be handled carefully to avoid slips and plant damage.

Moss and Algae Prevention Tips
- Trim Overhanging Branches: Reduce shade and debris, discouraging moss and algae growth.
- Improve Drainage: Ensure gutters are clean and shingles are in good condition to prevent water accumulation.
- Use Preventative Metals: Installing strips of zinc or copper under the top row of shingles can stop algae before it starts, as these metals release particles that inhibit growth when it rains.
