The main disadvantage of hurricane shutters is their cost, as they represent a significant upfront investment compared to other storm protection options. Another disadvantage is that some shutter styles require manual operation from the outside, which can present challenges for individuals with mobility issues. Additionally, shutters require regular maintenance, such as lubricating tracks and inspecting fasteners, to ensure they function correctly. Neglecting upkeep can lead to corrosion or damage, reducing their effectiveness when you need them most.
