Although homeowners often overlook this fact, too much exposure to the sun can cause the roof to deteriorate. The degeneration of the material can cause the rooftops to thin out, leading to leaks and other irreparable damages.

UV Light and IR Radiation
The sun’s ultraviolet light is so strong that direct exposure to it can dry out the rooftops,
forming cracks and causing the roof membrane to thin out. When the solar light oxidizes
the moisture in the asphalt, leaving the oils to dry out, it weakens the entire roof surface.
Infrared radiation, on the other hand, damages roof by way of temperature changes.
Unknown to many, roof materials can expand and contract, depending on the weather. At
high temperature, the roof expands, and at low temperature, it contracts. The more the
temperature fluctuates, the more frequently the roof expands and contract. This thermal
cycling makes the cracking noises on the roofs.
The problem with this process is it causes the flashings to loosen due to the erratic roof
expansions and contractions, leading the entire roof field to loosen from its foundation.

3. Roof Protection
Roof protection is similar to skin protection. Both need a layer of shield that significantly
reduces direct exposure to the UV and IR radiations. While the skin needs a sunblock, the
roof requires a strong and solar resistant coating.
During the hottest days, when the weather fluctuation is at its most active, the roof suffers
from heat shock, reducing the strength of seals and fasteners. This is where a good
reflector plays a vital role in roof protection.
Quality coating, for example, refracts the solar radiation away from the roof surface,
effectively shielding roof from the heat and preventing asphalt degradation. It safeguards
the moisture and oils of the roof, thus maintaining quality, strength and integrity of the
material.
It is advisable for homeowners to apply roof coating with high reflectivity and emissivity to
better ensure that the heat and radiation return into the atmosphere. This will not just
prolong roof life, but also efficiently minimise energy consumption and cooling costs.
