4. POINT_UP OR BEDDING CONCRETE is under ridge and rake tiles on your roof. It covers the top seam between two fields of tiles. In time, 8 to 10 years, cracks appear and pieces of concrete become loose. Cracks can be filled with mortar repair but missing or loose concrete must be
5. OUT OF ALIGNMENT occurs when field tiles, for several reasons, move out of position. That action exposes pre-drilled nail holes and can rot the baton boards and sheeting under the system. By moving the tiles back into position the problem and the leak are removed.
6. METAL FLASHINGS are used to cover voids in side seams, penetrations, and valleys. These flashings weather and fail in time. Caulk is only a band-aid and not a solution because it fails in a short time. Flaws should be addressed and replaced.
7. ANIMAL ATTACKS mainly occur as squirrels eat lead flashings. The simple answer is to rim the pipe jacks with silicone caulk. For some reason the squirrels hate this caulk and go to your neighbor’s house for lunch.
8. DAMNING IN THE VALLEYS occurs when organic material in this area rots and turns into dirt. As the dirt builds up it creates an obstruction. When the dam is finally created it allows the water to back up under your tile roof system and causes a leak. Valleys should be cleaned
once a year after the leaves have fallen.
9. POOR WORKMANSHIP occurs when there is a lack of supervision, the wrong materials are used, band-aids are applied, and work is done by people who do not understand tile roofs. A tile roofing company with a detailed scope of work is the answer. Watch the materials that
they use and who does your work.
10. DESIGN FLAWS usually happen in the valley and roof pitch area. These flaws are the reason behind the leak that has been a problem for years. Proper flashings and pitch adjustments solve these problems.
