Exploring moss growth on different roof materials.

Moss growth on roofs is a common problem that many homeowners face. Not only can moss damage your roof, but it can also make it look unsightly. The good news is that choosing a suitable roof material can help prevent or minimize moss growth. This blog will discuss which roof materials are better or worse for moss growth.

Better Roof Materials for Moss Growth


Best Materials to reduce Moss Growth.

  1. Metal: Metal roofs are one of the best materials for preventing moss growth. Moss doesn't like the metal surface and can't establish roots, making it easy to wash off. Also, metal roofs are durable and long-lasting, so you won't have to worry about moss growth for many years.

  2. Asphalt: While asphalt roofs are susceptible to moss growth, they're still better than other materials like wood or tile. The granules on the surface of the shingles create a rough texture that makes it difficult for moss to establish roots. However, if the granules start to wear away, the surface becomes smoother, and moss growth can become a problem.

  3. Zinc or Copper: Installing strips of zinc or copper near the ridge of your roof can help prevent moss growth. When it rains, the water runs over the metal strips, and the zinc or copper ions prevent moss from growing. These strips are an inexpensive and effective solution to moss growth.

Worse Roof Materials for Moss Growth.

  1. Wood: Wooden roofs are a prime target for moss growth. The rough texture and porous nature of wood make it easy for moss to establish roots and grow. Additionally, wood can rot if moss is left to grow for an extended period.

  2. Tile: Similar to wood, tile roofs are also a prime target for moss growth. The porous surface of tiles allows moisture to seep in, providing an ideal environment for moss to grow. Additionally, moss growth can cause tiles to crack or break, leading to costly repairs.

  3. Slate: While slate roofs are durable and long-lasting, they're also susceptible to moss growth. The rough texture of the slate provides a perfect environment for moss to establish roots and grow. Additionally, moss can cause the slate to become discoloured or stained, affecting the appearance of your roof.

What to do if I have moss growing on my roof?


If you've noticed moss growth on your roof, it's crucial to take action to prevent further damage. Here are some steps you can take to deal with moss growth on your roof top:

  1. Safety First: Before starting any work on your roof, take proper safety precautions. Wear slip-resistant shoes or boots with good traction, and consider using a safety harness if you're uncomfortable working at heights.

  2. Remove the Moss: Use a soft-bristled brush or broom to remove the moss from your roof gently. Be careful not to scrub too hard or use a pressure washer, which can damage your roof. If the moss is particularly stubborn, you can use a moss removal product that's safe for your roof material.

  3. Clean Your Gutters: Moss can also grow in your gutters, so clean them out regularly. Clogged drains can cause water to overflow, leading to water damage and additional moss growth.

  4. Prevent Future Growth: To prevent future moss growth, consider installing zinc or copper strips near the ridge of your roof. These metals release ions that can help prevent moss growth. Keep your roof clean and debris-free, as debris can trap moisture and provide a breeding ground for moss.

  5. Seek Professional Help: If you're uncomfortable working on your roof or the moss growth is extensive, consider hiring the Outdoor Maintenance Company to help. We can safely remove the moss and treat the roof to prevent future growth.

In conclusion, moss growth on your roof can be unsightly and cause damage if left unchecked. Taking proper safety precautions and following these steps can effectively remove the moss and prevent future growth.
