The sun damages roofs by a process called photo-degradation.  During this process ultraviolet photos with high energy content disrupt chemical bonds in polymers (long chains of similar subunits).  The absorption of the UV rays causes either breakage or crosslinking of polymer chain, changing both chemical and physical properties of various roofing materials.  After UV rays…
