The answer to 'why is my skylight worn out' is that skylights are exposed to the elements and can deteriorate over time due to factors like UV radiation, weather, and age. Common symptoms of a worn-out skylight include leaks, condensation, cracks, and fading or discoloration of the materials. Possible solutions include repairing or replacing the skylight, or installing a new one if the existing one is beyond repair.
Skylights are vulnerable to wear and tear because they are constantly exposed to sunlight, rain, snow, and other weather conditions. Over time, the sealants, gaskets, and other components can break down, leading to leaks and other problems. Additionally, the glass or plastic panels can become cloudy, discolored, or cracked, reducing the skylight's effectiveness and appearance.
