Clay tile roofs are stunning and tend to last a long time.
Most homeowners, unfortunately, don't know there's superior roof technology that looks just like clay tile roofs, without the disadvantages.
HAIL: Hail damage breaks/cracks the clay or cement tiles.
IMPACT: Impact damage occurs when the roof tile's ability for water shedding is decreased.
Clay or cement tile roofs can be repaired, to a certain extent.

Clay tiles are brittle materials and shatter when impacted by hail stones. The thinnest and least supported areas of clay tiles on the roof are the most vulnerable to breaking. It’s the overlap of interlocking clay tiles on the roof that break first. When performing a hail inspection on a clay tile roof, it’s essential to look for the characteristic semi-circular fractures at overlap. On S-Shaped clay tiles, the trough or concave area, is much weaker than the convex area because clay tiles are much stronger in compression than tension.
Wind damage on clay tile roofs usually starts in areas of the roof with the greatest uplift forces due to the bernoulli effect. These areas can be: windward roof corners, windward eaves, leeward sides of ridges, and windward rakes. The higher the roof, the greater wind force is generated. The density of the trees around the property help lessen the impact of the wind.
Footfall Breakage are the most common type of mechanical damage on clay tile roofs. The pattern of the breakage is the best way to tell the difference between wind/hail caused cracks versus footfall breakage. Determining the difference between footfall damage and wind/hail damage is not an exact science, but it does require supporting evidence to prove wind/hail damage caused the cracks on the clay tile roof.
