Hailstones are chunks of ice that vary in size, shape, and hardness, and are produced by the turbulent updrafts of thunderstorms. Because of hail’s variations, hail impact-caused marks on a roof and surrounding areas have various sizes, shapes, and depths. Hailstone-caused impact marks are generally rounded, but not perfectly circular.

Typically, the larger the hail, the fewer and further 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 conditioning unit fins, 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 impact. This can be important because perpendicular impacts transfer the most impact energy to the shingles.

Hail impact caused “spatter marks” – areas where the oxides and grime had been cleaned away from the cabinet of an A/C unit. These marks can help determine the size, frequency, relative hardness, and fall direction of hailstones. Inset, hail-caused spatter marks on a wooden fence.

Collateral Indicators of Hail Damage in Atlanta

Do you see hail marks on fences, A/C units, vents, metal trim, etc.?

These marks can tell you about a hailstorm, such as when it occurred, from which direction hail fell, and sizes and relative hardness of hailstones. The fins of an A/C unit, for example, can be dented by hail as small as ½ inch. The width of a dent in A/C unit fins is approximately 80% of the size of the impacting hailstone.

Are hail caused chips in shingle butts and edges damage?

Generally not. Chips are not damage unless joints between shingles or areas not protected by granules are exposed.

Directionality

Hailstones often are driven by wind. Because of this, they strike the roof at an angle from a predominant direction. Those slopes of the roof facing the storm (windward) receive more impacts and impacts of greater severity than slopes not facing the wind (leeward).

Wind Damage in Atlanta

wind damage atlanta gaWind damage typially begins at the areas of the roof with the greatest uplift forces due to aerodynamic effects such as ridges, windward roof corners, windward eaves, leeward sides of ridges, and windward rakes. Greater wind speeds, and hence, greater wind-generated forces, are found higher above the ground. The exposure of the building plays a large role in the wind forces a roof experiences, suchs as the surrounding terrain, vegetation, and other buildings. Wind-generated forces lift unbonded shingles and even debond marginally sealed shingles. Shingles can be bent upslope and creased along upslope edges of exposures, or torn away completely. Still stronger winds can tear away areas of shingles from slopes.

Sometimes, wind damages reveals fastening problems. A shingle installed with too few or improperly placed nails or staples can be more easily damaged winds.

Wind exerts positive and negative pressures as it flows over and around a structure. The areas of greatest uplift are at the windward eave and the leeward side of the ridge; those are the areas where wind damage initiates.

  • Area of shingles torn away at the windward corner. The weathered plywood decking and the bottoms of singles were weathered extensively due to their long-term exposure.
  • Shingle tab creased along its upslope edge by wind. Sealant on the underside of the shingle indicated the tab had been bonded to the underlying shingle previously.

This tab straddled a shingle joint and its bond had been broken prior to the recent wind event as indicated by oxidized sealant surfaces. Notice that strains within the roof had torn the tab in the upslope course.

Creased tabs from periodic wind effects. Note the different colors of exposed asphalt within the creases. The gray asphalt color (upper left tab) had been damaged some time ago as the exposed asphalt had oxidized. In contrast, the black-colored asphalt (lower right tab) had been damaged recently.
