Timber and Moisture – the # one enemy

A recent inspection and assessment revealed just how damaging the effects of moisture on timber can be. The building in question was a large industrial timber portal frame (main structure) where attachments to the roof had been retrofitted and these has caused leaks through the roofing. The water entry resulted in severe decay of the main pine portal rafters that have impacted their structural adequacy with maybe only 20% of original capacity remaining. Scary stuff!
