What is the primary drawback of using inadequate support for ledger boards?

The primary drawback of using inadequate support for ledger boards is structural instability. Ledger boards are critical components used to support decks and other structures. They are typically anchored to the building's framing and provide the necessary support for the weight of the deck and any additional loads, such as furniture and occupants.

When the support for ledger boards is inadequate, it can lead to several serious issues. The most immediate concern is that the deck could become unstable, leading to potential failures. This may manifest as sagging or even collapse under load, posing significant safety risks to anyone using the deck. Structural instability can also cause damage to the building itself if the ledger board pulls away from the structure, leading to issues such as water intrusion and structural compromise over time.

While increased costs, higher maintenance, and increased insulation needs might be relevant considerations in various construction and installation scenarios, they do not directly address the immediate safety risk associated with inadequate support of ledger boards. The primary concern remains the integrity and stability of the structure, making structural instability the most pertinent drawback.
