Common Issues Found During Metal Roof Inspections
Corrosion and Rust
Metal roofs, when exposed to persistent moisture or incompatible materials, can fall prey to corrosion and rust. Especially concerning are areas around fasteners, seams, and flashings where minor rust can quickly escalate into significant deterioration. A timely inspection by a qualified roof inspector can detect early signs, offering recommendations for maintenance or replacement.
Expansion and Contraction
With Australia’s soaring summer temperatures, metal roofs experience expansion. This natural behaviour can cause undue stress on seams and fasteners, potentially leading to their failure. Having your roof inspected regularly ensures that these shifts are monitored, and any resultant strain is addressed before causing structural issues.
Scratches and Punctures
Factors like falling debris, wildlife, or unintentional foot traffic can lead to scratches and punctures on a metal roof. While they may seem minor initially, these damages can become entry points for water and pests. A detailed roof condition report will identify these issues, advising on immediate remedial actions.
Inadequate or Failed Fasteners
Fasteners are pivotal in maintaining the metal panels’ position. Over time, environmental factors or poor installation can cause them to loosen or fail, compromising the roof’s safety. An experienced metal roof inspector will thoroughly evaluate the fasteners and any roofing fixtures that have been installed, ensuring their optimal functionality.
Poor Installation
A metal roof’s efficiency heavily relies on its installation. Common installation errors, such as improper overlapping or incorrect fastener placement, can jeopardise the roof’s longevity. Routine inspections can identify and rectify these potential pitfalls early on.
