We completed a job today at Helensvale, where the customer had a severe roof leak in one section. On inspection, we lifted the tiles above the affected area and found that the existing sarking in that section was gaping and loose and not pulled firm. We therefore removed the tiles in this section, repaired the sarking to sit tight and flat once again and reinstated the roof tiles.
Sarking is an important element in a roof, as it prevents water from penetrating into your roof cavity, onto your roof trusses, insulation, ceiling and plaster. Depending on the environment and location surrounding your home, in some cases moisture tends to condense on the underside of the roofs when there is a particular temperature difference between the roof space and the exterior (e.g. cold nights). This condensed water drips onto the trusses, insulation and ceiling and can cause timber to decay and plaster to stain and deteriorate.
Sarking is a great extra protection in your roof, an extra 'insurance policy' and is recommended to preserve the longevity of your home.
