EPDM
EPDM (Ethylene Propylene Diene Monomer) is a type of rubber roofing material that's widely used in commercial and residential buildings. Think of it as a large rubber sheet that's laid over flat or low-slope roofs to keep water out. It's popular because it lasts a long time (20-30 years), doesn't cost too much, and is easier to install than many other roofing materials. When you see this on a resume, it usually means the person has experience working with flat roof installations or repairs. Some people might also call it "rubber roofing" or "synthetic rubber roofing."
