How to Spot Hail Damage on Roof?

Generally, hail damage is very vulnerable for the roof and roof covering materials, and hail damages create a huge impact on those roof covering materials as well as other properties.

A hail storm can be very destructive and dangerous. So, there are some factors to determine the impact of hailstorm damages, which affects the different types of shingles and roofing materials, those are-

1. Wind

In the time of storm, the wind speed varies continuously; so, the direction and speed of wind are continuously changing. This changing direction of Hail affects the location of roof shingles and other roofing materials.

2. Size and Density

The intensity of the storm is directly proportional to the size and density of the hail; so, if the size of the hailstorm is more, then the damage is also serious. Hail storms may be very small, or sometimes it is huge.

Hailstorms carry hailstones that do not have smooth edges; so, the impact of those hailstones creates a deep impact on your roof shingles or roofing materials.

3. Building materials

Building materials also play an important role. Different types of building materials absorb different hail impacts. Due to Hail, dings in gutters, aluminum siding, asphalt shingles have happened.

Wooden shingles or vinyl siding are also badly affected due to Hail because they are not as strong as aluminum. Hailstones are very dangerous, and small hailstones have enough capacity to damage a roof; so, the longevity of the roof could affect this effect. Hailstones do not have smooth edges, and they are rough and sharp enough to damage a roofing material easily.

4. Barriers:

Barriers can protect your buildings or your property from dangerous hail damage. So, barriers like fences, homes near your house, natural barriers like tree covers, landscaping, etc. It can protect you from the hail damage effect.

What Is Hail and How Does It Form?

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 to Subzero 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 back to its original form, that is, liquid rainwater. Thus it can be said that Hail is generally formed keeping a lot of ice pallets together.

The formation of Hail can be generally witnessed in cold regions. In those regions, and in 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, in fact, 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. As the lower layer of air also consists of moisture; thus the raindrops collect more moisture and turn slightly bigger.

Due to the up drift of air, the raindrops again go into the upper layer of air, falling at a Subzero temperature and again forming ice pallets, which is slightly bigger than before. As this cycle goes on continuously, the ice pallets become bigger and bigger. 

Through this cycle, a time comes when the layer of ice cannot hold the weight of the ice; thus, it falls to the ground. Hails are generally the pieces of solidified raindrops formed through the cycle of transpiration and evaporation and have a size bigger than 5 millimeters.
