A cement ledger board is a horizontal board that supports the siding on a house. It is typically made of cement or concrete and is installed around the perimeter of the house, just below the siding. Ledger boards provide a solid and stable base for the siding and help to keep it in place.
If a cement ledger board becomes chipped or damaged, it can compromise the integrity of the siding and lead to water damage or other problems. It is important to repair any chipped or damaged ledger boards as soon as possible.
