With over 20 years inspecting and troubleshooting roof Issues, we felt it might be helpful to share our observations, we feel by starting with #1 as being the greatest cause for repair calls, this may bring some perspective to the issue of these terrable, relatively newer type pipe flashings, that have for the most part, taken the place of the good old fashioned and apparently eternally lasting Lead Pipe Boot, that seemes to be slowly being fazed out, we feel the progression 1-10 is for the most part accurate, however may vary in your state or area.

#2 – Missing Shingles – Related To Wind Or Storm Damage.
#3 – Slipping Shingles – Related To Poor Workmanship/Installation or Poor Nailing Technique.
