40 Hour Property and Building Inspection Practice Test

Is it true that the proper way to flash a ledger board involves extending the flashing from under the siding?

1. True

2. False

3. It depends on the siding material

4. Only in certain climates

The correct answer is: False

The correct response emphasizes that the proper way to flash a ledger board does not involve extending the flashing from under the siding. Flashing is essential in preventing water intrusion, especially at critical areas such as where a ledger board is attached to a building. When installing a ledger board, flashing should be applied above the board to direct water away from the structure rather than trying to extend it under existing siding. Extending flashing under the siding can create a situation where water is trapped behind the siding, potentially leading to moisture issues, mold, or wood rot. It is crucial to ensure that the flashing is properly installed in a way that allows water to run off, rather than allowing it to flow beneath the siding where it is more likely to cause damage. This approach not only provides a better seal against water intrusion but also adheres to best practices in construction and building safety.
