Timber is one of the oldest building materials known to man and is still the least respected of all on most building sites. It is probably its resilience to misuse which allows bad site practices in the storage and handling of timber to be tolerated. Generally it is only those timbers which are seen in the finished building which are afforded some respect and protection, whilst the often unseen structural timbers are frequently left unprotected and poorly stacked. Stress graded floor joists are not infrequently used as scaffold boards or barrow runs, and after having successfully survived these temporary functions are then built into the property.

The practicalities of construction work make it almost impossible to protect timbers completely, immediately after they are fixed on the house, but rapid enclosure of the roof structure and good ventilation will do much to prevent subsequent problems resulting from shrinkage on drying out.
