Hail, What Is It?
Hailstones are chunks of ice produced by the turbulent updrafts of thunderstorms. Hailstones vary in size, shape, and hardness. Thus, hail impact-caused marks on a roof and surroundings have various sizes, shapes and depths. Hailstone-caused impact marks are generally rounded, but not perfectly circular. The larger the hail, typically the fewer and farther apart the hailstones fall. Since the pattern of hail fall is random, their impact marks on the roof are widely distributed. Hail impact marks of varying sizes, shapes, and depths can appear in metal vents, flashings, air condition unit fans, and other exposed surfaces. These are indicators of hailstone size, frequency, and fall direction. Keep in mind that hail usually is wind driven, thus the windward side of the roof would sustain the most direct impacts. This can be important because perpendicular impacts transfer the most impact energy to the shingles.
Functional Damage: When is a composition shingle damaged by hail?
Functional damage of roofing materials is a reduction in water-shedding capability or expected long term service life. Composition shingles are functionally damaged when they are fractured by hailstones. The damage is immediate and noticeable visually and/or by feeling the top surface of a shingle. A hail-cause fracture is always visible in the bottom surface of a shingle. Granule loss from a hailstone impact which does not fracture the mat normally does not affect the life of the shingle and is not functional damage. The definition of functional damage, as applied to composition shingles, is based on nearly 50 years of research, testing, and field experience, and has been published in peer-reviewed literature.
