Hail Damage To Tile Roofing Haag

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.

Hail damage to tile roofing haag.

Hail spalled granules from the nominally flat mod bit membrane exposing asphalt at the rate of 4 spalls per roofing square. We have undertaken a study of various roofing tiles. Currently in addition to our forensic evaluations we offer desaturation core removal and other types of laboratory analysis through our research testing. A concrete void b lack of slurry coat c missing tile corner and d broken tiles from foot traffic.

Concrete tile defects not caused by hail. 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. 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. Because seamless gutters are frequently feature aluminum or copper construction the signs of hail damage include telltale denting.

These procedures were later published formally by marshall and herzog 1999. 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. Because a tile roof with hail damage can lead to roof leaks mold or other structural problems. Hail also fractured the membrane reinforcement at the rate of 1 fracture per square of roofing.

A test panel and b. Haag engineering is proud of its 96 years of engineering expertise. Gutters are also susceptible to hail damage. The fractures could be repaired and the granules could be replenished economically.

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. 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. Moisture damage to tiles has involved surface peeling delamination erosion and pitting just to name a few problems. At the same time haag refined the procedures for assessing hail damage to a roof to include examining test squares in order to quantify the damage and applying a repair difficulty factor.

Today we re going to look at hail damage photos. Haag also publishes a monthly blog with informative and timely articles by our engineers and other technical staff. If your tile roof has hail damage you need to get it fixed as soon as possible.
