New Hail Damage to Shingles
Recent hail impact damage to asphalt shingles will have the following characteristics:
- Asphalt exposed will be dark black in color.
- Coincident soft spot (“bruise”) with freshly exposed asphalt.
- There may be some loose granules remaining within the impact area.
- No shrinkage of reinforcement at impact-caused fractures.
- Other collateral indications of recent large hail
Recent hail impact damage to asphalt shingles will have the following characteristics:
- Bright hail impact mark/indentation on the wood. Coincident fracture with bright-colored wood in the fracture.
- Punctured area in wood that exposes brightly-colored underlying wood. Broken pieces of wood still present.
- Bright marks or indentations in the cedar from hail impact are readily visible. The marks and indentations do not represent functional damage, but the presence of hail and relative size(s) normally can be confirmed.
- Splits from hailstones occur at the moment of impact. Marks or indentations in the wood without splits are not damaging to the wood.
Old Hail Damage to Shingles
Old hail impact damage to asphalt shingles will have the following
characterics:
- Asphalt exposed will be weathered gray in color.
- “bruised” area is now bare, or remaining granules are not particularly loose.
- There is shrinkage or curling of the shingle reinforcement from the center of the impact area.
- No collateral indications of recent large hail. Possibly collateral indications of large hail such as dented metal, but without fresh spatter marks.
Old hail impact damage to asphalt shingles will have the following
characterics:
Old Hail Damage to Shingles
- Random aspects of hailstones include size, shape, density, and fall pattern.
- Very large hailstones often have irregular shapes and can have knobs or spikes.
- Larger hailstones generally are fewer than small hailstones when both are present in a storm.
- Hailstone trajectories and speeds are affected by size of the stones and the wind in the hailstorm.
- Impact energy from a hailstone increases exponentially with hailstone size (see kinetic energy Table 1).
- Perpendicular impacts impart the most energy; glancing blows transmit less energy.
| HAIL SIZE (IN) | TYPICAL DAMAGE THRESHOLD |
|---|---|
| 1/2 | FEW, IF ANY, ROOFS DAMAGED. Bushes and trees– leaves stripped; crops damaged. Oxidation coatings on paint, wood, metal– spattered. Thin elastomeric coatings on polyurethane foam roofs– cracked or broken. Thin aluminum vents, fins on air conditioning units, lead sleeves on soil stacks, window screens, aluminum awnings– dented. |
| 3/4 | THRESHOLD SIZE FOR DAMAGE TO ROLL ROOFING AND DETERIORATED ASPHALT COMPOSITION SHINGLES, ESPECIALLY WHERE UNSUPPORTED. Painted wood surfaces, deteriorated gray-black slates (especially at corners)– chipped. Most aluminum vents, flashings, valleys, siding– dented. |
| 1 | THRESHOLD SIZE FOR DAMAGE TO MOST LIGHTWEIGHT ASPHALT COMPOSITION SHINGLES. Thin and/or deteriorated wood shingles, shakes– occasionally punctured or cracked. Single-pane windows, thin skylight shells– cracked or broken. |
| 1-1/4 | THRESHOLD SIZE FOR DAMAGE TO MOST HEAVY WEIGHT ASPHALT COMPOSITION SHINGLES, WOOD SHINGLES, AND OLDER MEDIUM SHAKES. Automobile body metal– dented; galvanized metal vents– dented. Older plastic skylights– cracked or broken. |
| 1-1/2 | THRESHOLD SIZE FOR DAMAGE TO CLAY TILE, SLATE, MEDIUM SHAKES, AND MODIFIED BITUMEN SINGLE-PLY MEMBRANES. Automobile body metal– extensive denting. |
| 1-3/4 | THRESHOLD SIZE FOR DAMAGE TO HEAVY SHAKES AND CONCRETE TILES. Metal vents– caved in. Bare spots and blisters on deteriorated built-up roofs– bruised or punctured. |
| 2 | THRESHOLD SIZE FOR DAMAGE TO JUMBO SHAKES, WELL-SUPPORTED UNBALLASTED BUILT-UP ROOFING, AND UNBALLASTED EPDM. |
| 2-1/2 | THRESHOLD SIZE FOR DAMAGE TO WELL-SUPPORTED BALLASTED BUILT-UP ROOFING, BALLASTED EPDM, AND METAL PANELS. |
| Notes
1. Threshold is the smallest hail size at which damage can occur.
2. These guidelines are for hard hail ice hailstones that strike the impacted material in relatively good weathered condition (unless noted) perpendicularly to it surface. 3. These general guidelines apply in most circumstances, but there are exceptions. Determining factors include material properties, deteriorated condition, and underlying support. 4. This information is based on testing and field experience. |
Hailstones fall during some thunderstorms, with hailstones 3/4-inch diameter or larger being one of the National Weather Service (NWS) criteria for a severe thunderstorm. The central portion of the United States is one of the parts of the world where large hail is most frequent (see Figure 1).
Hailstone Formation Process:
Hailstones are “cycled” from lower to upper regions of a thunderstorm (cumulonimbus) cloud until the storm updrafts are no longer able to suspend the weight of the hailstones (Figure 2). A layer of ice accretes onto the hailstone each time it is carried upward and downward through the thunderstorm cloud. Milky, white-colored rings of less dense ice are formed high in the cloud where super-cooled water droplets freeze and entrap bubbles of air. Transparent rings of ice are formed low in the cloud nearer the freezing level in the atmosphere where greater quantities of liquid water are available (Figure 3).
Hailstorm Path:
In typical severe thunderstorms, the swath of hail will contain the largest hailstones in only a portion of the path, with smaller pea- to marble-sized stones found throughout the swath (Figure 4). At a given property location, falling hail will leave marks or dents on many different surfaces or materials. This can provide information on the relative size(s), quantities, and direction of the hailfall (Figure 5).
