Hail Damage To Tile Roofing Haag

Actual hail damage to clay or concrete tiles is typically characterized by crescent shaped fractures at the edges shattered tiles or star shaped fractures emanating from the point of impact.

Hail damage to tile roofing haag.

Hail caused damage to an asphalt shingle in roofing is rup ture of the reinforcing mat or displacement of granules suf ficient to expose underlying bitumen. Because a tile roof with hail damage can lead to roof leaks mold or other structural problems. In many cases these characteristics are accompanied by impact spatter marks within and or adjacent to the damaged area. Hail spalled granules from the nominally flat mod bit membrane exposing asphalt at the rate of 4 spalls per roofing square.

The fractures could be repaired and the granules could be replenished economically. Hail also fractured the membrane reinforcement at the rate of 1 fracture per square of roofing. When a hailstorm occurs damage inspectors unfamiliar with these products can erroneously conclude that certain anomalies with the roofing tile had been caused by hail. Hail is a powerful force of nature that can even damage roofs made with concrete tiles if the stones are large enough and wind speeds are high.

We have undertaken a study of various roofing tiles. A test panel and b. These procedures were later published formally by marshall and herzog 1999. Moisture damage to tiles has involved surface peeling delamination erosion and pitting just to name a few problems.

The former is a penetration of the shingle that in effect removes a ply of roofing and has the potential for water to reach the fasten ers or butted joints in the underlying shingle. Gutters are also susceptible to hail damage. A concrete void b lack of slurry coat c missing tile corner and d broken tiles from foot traffic. Haag also publishes a monthly blog with informative and timely articles by our engineers and other technical staff.

Today we re going to look at hail damage photos. Without a trained eye how can you tell if your tile roof has hail damage. Because seamless gutters are frequently feature aluminum or copper construction the signs of hail damage include telltale denting. Currently in addition to our forensic evaluations we offer desaturation core removal and other types of laboratory analysis through our research testing.

Concrete tile defects not caused by hail. Below is a sampling of some important technical papers haag engineering and research testing has published. Haag has a nearly century long track record of analyzing damage caused by weather phenomena including hail snow ice wind storm surge flooding lightning tornadoes and hurricanes.
