Our roofers performed an inspection on a home in Livermore California.   The roof inspection found a home with a tile roof.   Our roofing contractors explain the problems that are more pronounced with tile roofs with flatter-roofing tiles when compared to tile roofs with villa-style-roofing tiles (also known as spanish tiles).   A flatter-style tile will allow water to dam up easier underneath the tiles on the valley metal underneath.   This damming of water is caused by debris that blocks up underneath the tile in the valley flashing.  You usually can't see this blockage with the naked eye until the valley tiles have been removed.  This valley blockage usually begins to occur when roofs start reaching 10 to 15 years of age or older. Our roofers pay close attention to potential debris blockage in the valleys on older tile roofs when they start reaching the 10 to 15 year old mark.  Our roofers explain that as the roof is getting older, it becomes more of a threat to water leakage caused by the wearing out of the felt underneath the valley flashing or near the valley flashing from debris blockage which ends up coming into the house in the form of a roof leak.
