Fungi use spores as a reproductive mechanism. The wind scatters the spores which then establish and develop into new fungi. A favorite spot for fungal growth is on the roofs of houses. Over a period of time, the fungal growth on your roof will shorten the life span of the shingles. In addition, as your roof darkens from fungal growth, more heat is absorbed from the sun, reducing your roof s ability to reflect the UV rays.
Fungicides are chemical substances which are used to kill growths of fungi.
Great quantities of fungicides are sold each year. These chemicals are sprayed or dusted onto the fungal growth to kill fungal diseases. Molds are a member of the fungi family. Molds do not contain chlorophyll and, therefore, cannot produce their own food. Molds can live off of a tremendous variety of food sources as well as reproduce in large quantities.
