Hail damage to tile roofing haag.
A test panel and b.
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.
Concrete tile defects not caused by hail.
We have undertaken a study of various roofing tiles.
The fractures could be repaired and the granules could be replenished economically.
Without a trained eye how can you tell if your tile roof has hail damage.
Hail also fractured the membrane reinforcement at the rate of 1 fracture per square of roofing.
Because seamless gutters are frequently feature aluminum or copper construction the signs of hail damage include telltale denting.
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.
Today we re going to look at hail damage photos.
These procedures were later published formally by marshall and herzog 1999.
Below is a sampling of some important technical papers haag engineering and research testing has published.
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.
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.
If your tile roof has hail damage you need to get it fixed as soon as possible.
Hail spalled granules from the nominally flat mod bit membrane exposing asphalt at the rate of 4 spalls per roofing square.
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 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.
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.
Haag also publishes a monthly blog with informative and timely articles by our engineers and other technical staff.
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.
