Why rooftop cleaning matters (and how to do it)
In our coastal mountain climate, moss and algae thrive on rooftops. Left untreated, they can trap moisture and cause premature shingle damage, lead to costly leaks and structural issues, reduce your roof’s efficiency and overall lifespan, and diminish the appearance of your home or business. Regular cleaning not only protects the health of your roof but also saves you money in the long run.
Step-by-step guide on how to clean a rooftop
You can do this yourself, or hire a professional—either way, regular cleaning is key! Here’s how to DIY it:
Safety First
• Always use a sturdy ladder and safety harness.
• Wear non-slip shoes and protective gloves.
• Never work on a wet or icy roof.
Clear Loose Debris
• Use a soft-bristle broom or leaf blower to remove leaves, branches, and dirt.
• Avoid using hard tools that can damage shingles.
Apply Eco- Friendly Cleaning Solution
• Mix a gentle cleaning solution (such as water and mild detergent, or a specialized roof cleaner).
• Avoid harsh chemicals or high-pressure washing, which can damage your roof.
Remove Moss & Algae
• Apply moss/algae treatment directly to affected areas.
• Let it sit for the recommended time, then rinse gently with low-pressure water.
• For stubborn growth, use a soft brush (never metal bristles).
Rinse Thoroughly
• Use a garden hose or low-pressure washer to rinse away residue.
• Make sure water flows down toward gutters, not under the shingles.
Clean Gutters & Downspouts
• Remove leaves and buildup to ensure proper drainage.
• Flush with water to check for clogs.
Prevent Future Growth
• Schedule regular maintenance, especially in damp, shaded, or coastal environments.
