Mould in Canberra homes is rarely a random occurrence. In most cases, it can be traced back to a moisture problem, and one of the most common sources of hidden moisture is a poorly maintained or damaged roof.
When fascia and guttering become blocked or detached, water can overflow and run down the external walls or work its way under eaves. Damaged sarking or cracked pointing and bedding around ridge lines allows rain to enter the roof cavity, where it sits on insulation and timber, creating exactly the warm, damp conditions that mould needs to take hold.
Homeowners in Tuggeranong and Weston Creek have contacted us after noticing mould patches on internal ceilings, only to discover that the real cause was a slow roof leak that had been present for months. Addressing the source of moisture is the only permanent fix.
If you have mould appearing on ceilings or walls, it is worth having your roof inspected before spending money on surface treatments. Call Alpha Roofing ACT on 0458 807 882 or visit alpharoofingact.com.au.
