Moss is a small plant that thrives in damp and shady areas. Although moss adds an aesthetic appeal to the surroundings, it can cause significant damage to your roof. Over time, the moss can crack tiles, cause leaks, and lead to water damage. Therefore, it is essential to understand the effects of moss on your roof and the necessary measures to prevent it. In this article, we will answer the question, “Is it OK to leave moss on the roof?” and provide a comprehensive guide to moss prevention.

Is it OK to leave moss on the roof?

The short answer is no. Moss on the roof is not only unsightly but also harmful. It can cause significant damage to the roof if left unchecked. The growth of moss can crack tiles and cause blocked gutters and create gaps that allow water to seep into your home. The trapped water can lead to water damage, mould growth, and costly repairs. Therefore, removing the moss from your roof as soon as possible is necessary.

Effects of Moss on Your Roof

Moss growth on your roof can lead to various problems, including:

1. Cracked Tiles

Moss’s root-like structure penetrates the tiles’ surface, when the moss freezes it can create hairline cracks in the tiles. Over time those hairline cracks get worse and eventually tiles can begin to break up.

2. Water Damage

The trapped water in the gaps created by moss growth can lead to water damage. Water damage can be costly to repair and may cause structural damage to your home.

3. Mold Growth

Moss growth can create a favourable environment for mould growth. Mould growth on your roof can be hazardous to your health and costly to remove.

4. Decreased Lifespan of Roof

Moss growth can decrease the lifespan of your roof. The trapped water and mould growth can weaken the roof’s structure and lead to premature failure.
