**The life of a roof depends on local weather conditions, building and design, material quality, and adequate maintenance. Slate, copper, and clay/concrete roofs have the longest life expectancy while roofs made of asphalt shingles, fiber cement or wood shakes will fail sooner.
Asphalt Shingles (3 - tab)
BUR (Built-up Roof)

EPDM (Ethylene Propylene Diene Monomer) Rubber
