                   CLAY/CONCRETE
                   Almost Forever                                                     Clay or Concrete Tile
                   Clay or concrete roof tiles would appear to have it all: good looks, fire
                   resistance and extreme durability. Recent innovations also address
                   issues of stormwater management, and enable cool roof capability.
                   But the high cost of buying and installing masonry tile roofing has
                   relegated its use to regional styles and high-end housing. Since 2004,
                   its share of the residential roofing market has shrunk in the U.S., but
                   is growing steadily worldwide.
                     Nonetheless, a quality tile roof that is installed over a heavy-duty
                   underlayment and screwed to the roof deck (not just mortared)
                   should last for decades—if not a century or two—before it’s time
                   to remove them, replace the underlayment and put the tiles back
                   on. GB
