Final answer:
The word 'infrequent' fits in the blank to describe a leaking skylight, indicating that such an occurrence does not happen often but can cause significant issues when it does.
Step-by-step explanation:
A leaking skylight is a(n) infrequent occurrence. In this context, 'infrequent' means something that does not happen often. When a skylight is properly installed and maintained, it should not leak. However, over time, skylights can develop leaks due to weathering, improper installation, or damage. Leaks from skylights can lead to water damage inside a building, which is why it's important to address the issue promptly when it occurs. When using 'infrequent' to describe the leaking skylight, it suggests that while the situation is not common, it is still possible and warrants attention to prevent potential damage.
Skylights are structures on the roof that allow natural light to enter a building. They are usually made of glass or plastic and are designed to be watertight. However, over time, wear and tear or extreme weather conditions can cause skylights to leak.
The most common cause of skylight leaks is faulty installation or aging materials. If the flashing around the skylight is not properly sealed, water can seep in during rain or snow. Additionally, if the skylight itself is cracked or damaged, water can enter through those openings.
