This is due to the constant flux between daytime s heat and nighttime s cooler temperatures.
Uv radiation roof shingles.
In addition shingles are also more prone to thermal shock during summer.
But ultraviolet radiation affects the asphalt material from its chemical aspect.
Heat energy from the sun breaks down the chemicals in seam sealants and prevents them from doing their job effectively.
This wears on the shingles to begin with.
In fact uv rays and relentless sunshine is one of the most common reasons for shingle damage.
Uv light alters the chemical makeup of the shingle material.
Infrared radiation is a spectrum of light that generates significant amounts of heat on roof surfaces.
Solar reflective shingles are defined as having surfaces that primarily reflect considerably more ir radiation than normal roof surfaces.
As the material breaks down the oily substance covering the shingles evaporate which leaves the shingles unprotected.
Shingles are durable and look great but this will not be the case after overexposure to the sun.
The primary force that deteriorates exposed asphalt is ultraviolet or uv radiation.
The percentage of granules missing.
Uv rays and your roof shingles are durable and look great but after some time in the sun this is not the case.
The intense heat also causes the asphalt s oil to evaporate making the material brittle.
Uv radiation and your roof.
The oxygen mixes with the hydrocarbons which causes the coating of the shingles to break down.
Even though shingles have a protective coating this can deteriorate with extended contact with the air.
If you re worried about the quality of your roof sealants you may need to have an extra layer of protection installed on the roof.
Deep within the shingle the uv light alters the chemical makeup.
Uv radiation does this by altering the shingle s chemical makeup.
The intensity of the sun will cause shingles to deteriorate faster than usual especially if you re in an area with strong uv light or radiation.
Low quality asphalt is less resistant to deterioration.
However powerful uv radiation can compromise the integrity of your roof sealants over time.
However excessive rays of sunlight will damage your roof over time.
Understanding ultraviolet radiation and its effects on asphalt roof shingles generally heat expands the asphalt roofing material and at night the cooling causes it to contract.
