🏠 How to Clean Moss Off Roof Safely and Effectively
Moss on your roof isn’t just ugly—it’s dangerous. Left untreated, moss can damage shingles, trap moisture, and shorten your roof’s lifespan. At ClearView Home Services, we help homeowners across BC learn how to clean moss off roof surfaces safely and effectively. In this guide, you’ll get step-by-step instructions to remove moss, stop it from coming back, and protect your roof long-term.
🌿 Why Moss on Roofs Is a Serious Problem
In BC’s cool, wet climate, moss thrives—especially on asphalt shingles in shady areas. Moss retains moisture, causing shingle deterioration, mold, and even roof leaks. Learning how to clean moss off roof properly is essential to prevent costly damage.
🧰 What You Need to Clean Moss Off Roof
Before starting, gather the following tools:
-
✅ Garden hose (no pressure washer!)
-
✅ Long-handled soft-bristle brush
-
✅ Dish soap or roof-safe moss killer
-
✅ Plastic sheeting to protect plants
-
✅ Safety gear + ladder
-
✅ Zinc strips for long-term moss control
🧼 Step-by-Step: How to Clean Moss Off Roof
1. Prepare and Protect
Lay down plastic sheeting over plants, gutters, and garden beds. Moss-killing runoff can be harmful, so cover everything below the roofline.
2. Remove Loose Moss
Use a gentle spray from your garden hose to loosen moss. Never use a pressure washer—it can damage shingles. Then, use a soft brush to scrub the loosened moss off carefully.
3. Apply Moss-Killing Solution
Mix dish soap and water (1 cup per 5 gallons), or use a commercial moss remover. Apply it generously to mossy areas and let it soak for 20–30 minutes.
4. Rinse the Roof
Gently rinse off the moss-killing solution with your hose. Ensure all chemicals are washed away to protect your roof and landscaping.
5. Scrub Remaining Moss
Inspect the roof. If moss remains, scrub gently and reapply solution as needed. Patience here helps prevent roof damage.
6. Prevent Future Moss Growth
Install zinc strips at the roof’s ridge. When it rains, zinc ions wash down the roof and make the surface hostile to moss growth.

❓ FAQs About How to Clean Moss Off Roof
How often should I clean moss off my roof?
Check once per year. Clean moss as soon as you spot it to avoid damage.
Can I use bleach to clean moss off roof?
We don’t recommend it. Bleach harms plants and roofing. A professional-grade sodium hypochlorite mix, used safely, is far more effective.
