ROOF CLEANING

​

Should moss, algae and lichen be removed?

Moss and algae (glaeocaspa magma) both retain moisture. Moisture increases the rate at which moss, algae, mold, and lichen grow. When moss begins to grow on your roof, the rhizoids (the root-like anchoring structure of the moss) are embedded into the asphalt shingles and they use the organic material as a source of nutrients, causing the granular composition of the shingles to break down and loosen. As granules are loosened, the core of the shingle is left exposed to the sun, causing the shingles to rapidly degrade. Once this occurs, the life of your roof can very quickly be reduced by up to ten years. Considering the average roof costs between $8,000 to $12,000 to replace, we recommend a regular maintenance program to ensure your roof lasts the full length of its intended lifespan.
