An accelerated water-streaming
test was used to evaluate several roofing materials regarding their behavior to
colonization by
algae, by closely reproducing the phenomenon of natural biological soiling. A
set of roofing materials with defined physical and chemical characteristics was thus investigated
against the colonization by algae. Porosity, roughness and chemical composition
showed to be factors of influence in the establishment of those
micro-organisms.
