Which of the following is NOT a disadvantage of reflective roofs?

Reflective roofs, designed to minimize heat absorption and improve energy efficiency, can face several disadvantages. Among the options provided, the characteristic of enhanced aesthetics stands out as not being a disadvantage. Reflective roofs often come in various colors and finishes that can contribute positively to the appearance of a building, while improving its energy performance.

On the other hand, dirt pickup can be a concern, as reflective surfaces may attract and retain dirt, reducing their effectiveness and requiring more maintenance in terms of cleaning. Cost can also be a drawback; reflective roofing materials may have a higher initial price compared to traditional options, which can be a deterrent for some projects. Lastly, the limited life of coatings is a real issue for reflective roofs since the coatings can degrade over time due to exposure to UV light and weathering, necessitating reapplication to maintain their reflective qualities. Thus, while other options present challenges, enhanced aesthetics is a benefit that can add to the roofing system's overall appeal.
