A recent call-out to carry out a woodworm survey within a property's roof space.
Unfortunately, a heavy infestation of woodworm activity was identified throughout the roof timbers.
During the inspection, all roof rafters and ridge beams were also found to have exceptionally high moisture readings. Timber moisture levels above 20% can present a significant concern, potentially compromising the structural integrity of the timber and increasing the risk of deterioration or failure.
I have advised the client to seek the assistance of a damp specialist to identify and rectify the underlying source of moisture before any woodworm treatment is considered.
Potential causes of excess moisture can include:
Inadequate roof ventilation.
Damaged or slipped roof tiles.
Deteriorated roofing felt or membrane.
Defective lead flashing.
Roof leaks or other sources of water ingress.
It is always advisable to undertake appropriate surveys before purchasing a property where there is a potential woodworm issue.
