Tile roof’s have been popular for decades.  Majority of new homes built today have a tile roof system installed.  The major difference between the older and newer tile roof systems is the underlayment used.  The tile gives the roof an unique look to the tile that was installed, but the tile is solely aesthetic.  The waterproofing of the roof is the quality of the underlayment.  Over the years, the products being used are far more superior and will last longer than the original 15-20 years.  Most people believe that a tile roof is never re-placed…well, I’m here to tell you that is False.  Look at the following for information on quality material
