Introduction of Hail Damage to Asphalt Shingles
As humans came into this world, at first, they started living in caves made from Rocks. The primary intention for living in caves was to protect themselves from adverse environmental conditions such as rain, storm, wind, etc; and also, to protect themselves from the attacks of wild animals.
Although caves fulfilled their primary intention, humans with their developing brains, soon realized the need for more.
They eventually grew aesthetic and architectural sense, and also the need for permanent belongings. As caves were not able to fulfill that, humans started thinking of building their own “homes” rather than living in caves.
So, they started gathering materials and started building homes using their concept. With progressing time, the homes they have built soon started facing various challenges.
As the primary material for construction was Wood, many a time, then the fire broke out in their house (as wood is very much susceptible to fire), while in some other times, the wood easily decayed due to presence in moisture, which as well as indirectly responsible for the growth of insects.
Thus, facing such challenges, the construction materials evolved as well. With the time of evolutions of construction, the concept of asphalt shingles is coming. There has a controversy arises that how asphalt shingles are damaged by hail and actually what hail damage looks like.
What Is Hail and How Does It Damage the Asphalt Shingles?
In simple words, Hail can be defined as a crystallized piece of snow. Many a time hail is confused with the ice pellets, but that’s often not the case. Ice pallets are generally solid precipitation of particles less than 5mm, which are generally spherical and circular, but rarely conical in shape.
Ice pallets are generally formed as the raindrops fall through the cold air. The raindrops as they fall through cold air and clouds, soon lose their temperature and come in Sub-zero temperature.
As they come in Sub-zero temperature, a thin layer of ice is formed converting the liquid raindrops. Many a time, while falling through the air, a fall in temperature might be witnessed, thus again converting the ice pallets into raindrops.
The size of ice pallets is far smaller than the size of hail, so it does not damage any roofs while falling. Many times, while falling through the thin layer of ice is again broken and again reverts to its original form, that is liquid rainwater. Thus, it can be said that hail is generally formed by keeping a lot of ice pallets together.
The formation of hail can be generally witnessed in cold regions. In those regions and all other regions as well, the air temperature rises as the height gets increased.
Thus, the temperature of the air at a higher place is larger than the temperature of the air at a lower place, keeping the geotechnical coordinates the same. As per the concept of transpiration, the warmer air gets upward, while the colder air gets downward.
So, the process starts from the evaporation of water due to continuous heat. As the water evaporates from the surface sources, it gets stored up in the lower layer of air, which is warmer.
Due to the up drift of warmer air (meaning warmer air gets higher), the rainwater stored in the lower layer of air gets upwards. As the temperature of the upper air, is much below the lower air, the raindrops generally fall below Sub-zero temperature and form thin ice.
As the weight of the ice is greater than the raindrop itself, it falls in the lower layer of air. As it falls in the lower layer of air, it generally melts into raindrops again.
Hails are generally the pieces of solidified raindrops, formed through the cycle of transpiration and evaporation, and have a size bigger than 5 millimeters.
And also, the hail damage the asphalt shingles by many ways like some specialist says it is torn, punctured and fractures on the asphalt mats. Some time by the reaction of hail on the asphalt roof shingles, the granules are dislodged from the asphalt math of the impact area.

Hail Damage to Asphalt Shingles
Here, two different types of examination are as follows.
1. Inspect the Exterior Shingles
Due to storms, the roof of the houses is damaged widely because they are protected you as a front-line defense against tough outdoor weather conditions.
Then we check curling, granular loss, cracked shingles, missing shingles, etc. We need to hire a roofing contractor for inspection purposes or use a binocular.
2. Missing Shingles
Sometimes when a high wind storm has occurred then some asphalt shingles can be missing by the high wind and for this, some leaks create on the roofs. To avoid more serious water damage for leaks we should prevent the leaks by waterproofing seals.
Sometimes when there is seen a large number of shingles that are missing in this situation some homeowners are want to replace the whole roofing system.
Hail Damage of Asphalt Roof Shingles Components
On the market, today asphalt roof shingles are affordable and one of the most common roofs covering materials. In the asphalt roof shingles, the base materials are glass-fiber that is an inorganic material or the other one is paper that is an organic material.
With the limestone power, of asphalt an asphaltic mixture of composed and also another mineral stabilizer like fillers.
On the asphalt shingles, surface granules are applied to provide weight, color and to block the deleterious effect of the sun on the underlying asphalt.
In this asphalt roof shingles with a ceramic material, the crushed stone coated granules are used. The ceramic is used to provide the color of the ceramic.
Generally, the weight of the granules is one-third of the asphalt shingles, and one-third is asphalt and the rest of one-third is filler material.
In the total weight of the asphalt shingles, the weight of the mat is a small fraction. In various shapes, sizes, athicknessesess the asphalt roof shingles are available in the market.
Generally, the cost of the asphalt shingles will be increasing the heaver or thicker of the shingles. In the constructions, the asphalt shingles which are mostly used that’s are laminated and three-tab varieties.
Hail Damage: Granule Loss Study
In the asphalt roof shingles, how many granules are removed on the affected area that’s affect the water-shedding ability or the service life of shingles, this process named by the author is a granule loss study on asphalt shingles?
With a wire brush, the quantities of removing granules are varying from new glass-fiber and three-tab mat shingles. After that for ten years, for the weather conditions in Texas and Dallas, the asphalt shingles are exposed naturally.
Approximately, 5, 15, 45, 70 % ( percent ) of granules are removed from the total amount of granules of the asphalt shingles. An upside-down shingle was installed when by the weather the asphaltic mat was exposed.
On the south-facing over wood conventionally the asphalt shingles were installed on a 4:12 pitch. AtAfterhe the study at intervals of ten years period the shingles were examined as well.
The exposed asphalt, in one year, had oxidized grey but on the surface of the shingles has no visible evidence of crack or erosion. The shingles to shed water after five years have oxidized of the exposed shingles area but the functions of the shingles did not affect.
Without granules shingles, surface erosion was visible on the shingles and the other hand had become glass fiber had become exposed. Without granules, after 10 years in the shingles, no significant change was noted. Due to erosion, the life longevity is a decrease of the asphalt shingles.

Hail Damage: Assessing Hail Damage
Assessing hail damage on shingles is a long process that’s occurred step by step examination of other things around the roof and the roof shingles. By using of test squares methodology, Herzog and Marshall presented to a roof how to quantify hail damage.
On each directional roof slope in test squares are counted the number of hail damaged shingles, and whether the roof slope is required that determines the number of hail damage that’s happened on roof shingles, by the use of DURA formula it can be replaced.
If there have no underlying support or have little especially along eaves, rakes, ridges, and valleys by hail damaged shingles are particularly susceptible. To be broken or chipped also are vulnerable to shingles edges.
Therefore, must be examined the entire roof carefully, when you examined the roof you can see if there are have many months of exposed asphalt it will provide a grey color surface and if it is recently exposed then it will provide a weathered or black surface.
You can say which one is new hail damage and which one is old hail damage by the color difference.

What Is Functional Hail Damage to Asphalt Shingles?
Marshall and Herzog (1999) more specifically defined functional hail-caused damage to asphalt shingles as punctures, tears, or fractures (bruises) in the shingle mats (Figure 1). Shingle bruises are an indentation with a fracture in the mat that feels soft like that of an apple bruise.
How Can You Tell If a Roof Has Been Damaged by Hail?
Impact marks or dents along the splits. There are many other types of damage to shingles that can be mistaken for hail damage. For example, exposure to inclement weather and sunlight makes shingles brittle and gives them an aged appearance. This type of damage is normal wear and tear of shingles, which is sometimes misidentified as hail damage.
What Kind of Damage Can Hail Cause?
Most hailstones do not have smooth edges, which can impact the type of damage they cause. Building materials – Building materials absorb hail impacts differently. For example, hail can cause dings in aluminum siding, gutters or asphalt shingles, whereas it can crack vinyl siding or wood shakes.
What Exactly Is Hail?
Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. … Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze.
Where Does Hail Form?
Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing 0 °C (32 °F).
How Long Does the Average Asphalt Shingle Roof Last?
Vented properly and installed correctly, you should get around 80-85% of the life span out of an asphalt roof. That means you can expect to get about 20-22 years out of your 3-tab shingle roof and 25-28 years out of your dimensional shingles.
What Is an Asphalt Shingle Roof?
An asphalt shingle is a type of wall or roof shingle that uses asphalt for waterproofing. It is one of the most widely used roofing covers in North America because it has a relatively inexpensive up-front cost and is fairly simple to install.
How Long Does It Take for Asphalt Shingles to Seal?
The curing time for the tile adhesive seal depends on the manufacturer and should be taken into consideration when selecting the season for installation. In general, ceiling tiles take 48 hours to cure after activation of the strips.
Can Hail Damage Asphalt Shingles?
When hail hits, it can damage the roof or covering of your home as well as other personal property. For example, hail can cause dings in aluminum siding, gutters or asphalt shingles, whereas it can crack vinyl siding or wood shakes.
How Does Hail Damage Roof?
Hard hail impact or strong winds can also cause cracks in roof shingles, which results in a bare spot in your roof. When shingles are cracked, the shingles can no longer effectively protect your roof from any type of weather. Cracks as small as an inch can allow damage inside your home and roof.
How Can You Tell If You Have Wind Damage from Shingles?
Shingles are considered wind-damaged when they are torn, creased, or detached from the roof. Most commonly, wind damage occurs when three-tab shingles are creased by repeated lifting or flapping. Unsealed shingles without physical mat damage are not considered wind damaged.
