Sagging

A sagging roof line is one of the most visually obvious indicators of structural issues. On tile roofs, sagging may indicate that the rafters or trusses are undersized for the tile weight, that structural members have been weakened by rot or termite damage, or that the bracing system has failed. On metal roofs, sagging between purlins can indicate undersized purlins, excessive purlin spacing, or accidental overloading (such as the accumulation of heavy debris or water ponding). Gutter sagging is a separate but equally common issue, caused by bracket failure, fascia board rot, or excessive load from water and debris accumulation. A sagging gutter does not drain properly, leading to standing water that accelerates corrosion, attracts mosquitoes, and may overflow onto the wall below during rain. In Gippsland, roof sagging is encountered on older homes where original structural members have deteriorated over decades of service, or where DIY renovations have inadvertently compromised the roof structure (such as removing a load-bearing internal wall without providing an alternative support). Town & Country Roofing identifies sagging during roof inspections and can recommend structural remediation — from sistering rafters and replacing purlins to full re-framing where necessary — before installing the new roof covering.
