Roof ventilation #4: Moisture and ventilation in skillion roofs
<p>In skillion roofs, the roof cladding and ceiling run parallel, typically within 300 mm of each other. The roof space is generally inaccessible, with little natural ventilation, and the small roof space can accelerate problems with moisture. Skillion roofs need carefully designed and installed ventilation to reduce the risk of moisture-related problems.</p>
