Ledger rot is a serious issue that can compromise the safety of your deck, even when using exterior wood. This misconception that exterior wood won't rot often leads to problematic installations where the ledger board is fastened directly to the wood, trapping moisture and debris, which accelerates rot. In this blog we will go over understanding how ledger rot happens and how to prevent it.
The Risks of Direct Attachment
When a ledger is attached directly to the exterior wood, it can trap water and debris, leading to rot. This situation is particularly concerning in older structures where the ledger may not have been installed with proper spacing or flashing. It's essential to have a professional inspect for water damage if you suspect your ledger is causing rot. Ignoring this can lead to costly repairs and structural damage to both the building and the deck.
Preventative Measures
To prevent ledger rot, use a spacer between the wall and the ledger to allow for water drainage and air circulation. Additionally, proper flashing is critical to protect the structure. Properly flashing a ledger involves a shingling system where protective layers overlap, using gravity to divert water away.
The Importance of Flashing
Incorrectly flashed ledgers can lead to severe structural damage and create a habitat for wood ants, which can accelerate wood deterioration. Proper flashing is straightforward and essential for preventing these issues. Our tutorials offer step-by-step guidance on flashing techniques to ensure your deck remains safe.
Deck Failure Statistics
Deck collapses are alarmingly common and can result in serious injuries or fatalities. Since 2003, over 6,500 people have been injured and at least 29 have died due to deck collapses. Approximately 90% of these collapses are due to ledger board failures. Regular inspections and adherence to building codes are crucial in preventing these accidents​
The Consequences of Neglect
Deck failures are not only hazardous but can be deadly. The worst recorded accident killed 13 people in Chicago in 2003. Ensuring your deck's safety through proper construction and maintenance can prevent such tragedies. Deck collapses are more frequent in the summer months when decks are more heavily used.
