Recommendations

These skylights are old and beyond their life expectancy. And they show it. The acrylic is brittle and the skylights are actually a fall hazard for anyone on the roof. Replacement is due and recommended.

The skylights should be replaced with a product that has a better quality of light transmittance, more energy efficiency and made of a material, such as polycarbonate or high strength acrylic, that provides security and safety to both the employees working on the roof and the public below.
