How to remove moss from a roof

Moss, the unwelcome guest on your roof, may seem harmless at first. However, if left unchecked, it can wreak havoc on your roofing materials, lifting shingles and allowing water to seep through. Don’t let moss compromise the integrity of your home. Learn how to remove moss from your roof with the expert guidance from American Roofing & Construction.


Roof Cleaning Procedure

When confronting moss on your roof, safety should be your top priority. Dress in old clothes, slip-resistant shoes, and don safety glasses before you embark on this task. Spread a protective layer of plastic sheeting beneath your work area to shield plants from the cleaning product runoff.

With caution in mind, use a ladder to access the mossy area. For added safety, consider tying yourself to a safety line. If you opt not to use a safety line, exercise extreme care while on the ladder and the roof.

Avoid the temptation of using a pressure washer, as it can damage the shingles. Instead, employ a hose sprayer to wet down the mossy area, loosening it up for removal. Armed with a long-handled brush, scrub the shingles vigorously, ensuring you work in a downward motion to prevent pushing dirt and vegetation beneath the shingles.

To eradicate any remaining moss spores and residue, apply a moss-killing cleaner using a sprayer. Whether you choose a store-bought solution or a homemade mixture like a 50/50 blend of water and chlorine bleach, let it set for approximately 20 minutes. Then, rinse away the cleaner thoroughly.


How to Prevent Moss Growth on Roofs

Prevention is key when it comes to moss growth on roofs. Moss tends to thrive on north-facing roofs due to lingering moisture in the absence of direct sunlight. Additionally, roofs under the shelter of tree limbs may become mossy due to shade and the accumulation of tree debris. Take proactive steps to hinder moss growth by trimming tree limbs away from your house, allowing sunlight to reach the roof.

For persistently mossy roof areas, consider attaching strips of zinc or copper to the top of the roof. These metals release molecules that are lethal to moss and algae. Alternatively, explore special asphalt shingles containing copper as a long-term solution to prevent moss growth.
