🌿 Why Moss Grows on Roofs

Moss thrives in environments that are cool, damp, and shaded. Roofs with poor sunlight exposure, such as those shaded by trees or located on the north side of a building, are particularly susceptible. Moss retains moisture, which can lead to the following issues:

• Shingle Damage: Moss can lift shingles, allowing water to seep underneath and cause leaks.
• Roof Decay: The retained moisture can accelerate the decay of roofing materials.
• Aesthetic Concerns: Moss gives the roof an unsightly appearance, potentially lowering property value.

📅 When Is the Best Time to Remove Moss?

1. Late Spring to Early Summer

This period is considered the optimal time for moss removal for several reasons:(Metro Exterior Cleaning)

• Post-Growth Stage: Removing moss after its active growth phase prevents it from spreading further.
• Ideal Weather: Mild temperatures and dry weather provide a safe working environment.(Metro Exterior Cleaning, Palladium Roofing)

🧰 How to Safely Remove Moss from Your Roof

Removing moss requires careful attention to avoid damaging your roof. Here’s a step-by-step guide:

1. Safety First: Always use a sturdy ladder and wear non-slip shoes. Consider using a harness for added safety.
2. Remove Loose Moss: Use a soft-bristle brush or a broom to gently sweep away loose moss. Start from the top of the roof and work your way down.
3. Apply Moss Treatment: Use a commercial moss remover or a mixture of water and oxygen bleach. Apply according to the manufacturer’s instructions.
4. Rinse Thoroughly: After allowing the treatment to sit, rinse the roof with water to remove any remaining moss and cleaning solution.
5. Prevent Future Growth: Install zinc or copper strips near the roof ridge to prevent future moss growth.(Bob Vila)

According to Bob Vila, some sources suggest that the best time of the year to remove moss from roofs is early spring, when seasonal rains provide the moisture that the plant needs. But you can remove moss from the roof at any time of year. While you should apply moss-killing treatments in spring and fall when the plant is actively growing, it may be easier to brush and hose moss off the roof when it goes dormant in summer and becomes brittle.
