The True Culprit
More than Cleaning
Microscopic View of Gloeocapsa Magma Cells
If you look at a picture of swollen, poorly maintained shingles you can clearly see four forces working away at them. There is no question that the shingles are being attacked. Let us break down the four areas of shingle deterioration caused by algae and fungi:
1. Shingles break down from decomposition caused by algae and fungal filament root systems. In the picture to the left, you can see how the shingles have cracks in them, thus curling and swelling.
2. Shingles break down because algae and fungi have a hunger for limestone fillers. Limestone, which contains phosphates, is an excellent source of nutrients for algae and fungi.
3. Shingles break down from the waste created by the algae and fungi metabolizing the limestone fillers. This waste is acidic and damages the shingles.
4. Shingles break down because of excess heat caused from the darkening of the shingles. The darker the shingles get from algae streaking, the more heat they absorb. This excess heat dries the shingles and ages the petroleum in them.
