Zinc roofs are quite popular, owing to their longevity and durability. Many homes and commercial buildings alike use this material for roofing in and around Johannesburg. However, despite their longevity, these roofs can deteriorate over time, so it’s important to keep an eye out for signs of distress.
Here are some of the signs you might need domestic roof repairs in Johannesburg for your zinc roof:
Corrosion
The first thing you should look out for with a zinc roof is whether it has started to corrode. Zinc is naturally corrosion-resistant and will withstand the elements for a long time. However, it can still develop corrosion when exposed over a long period, particularly if it’s exposed to excessive moisture.
When zinc does start to corrode, it might develop white, chalky patches on the surface. If this isn’t treated properly, it can eventually spread, weakening the roof’s overall integrity and ultimately leading to leaks and structural damage.
Warping
When your zinc panels warp or buckle, your roof might become vulnerable to water leaks and damage. Warping and buckling can occur when your zinc roof has been exposed to extreme temperature fluctuations. This causes the zinc to expand and contract rapidly, which can lead to disfiguration.
Although this is not a common problem, it can happen over time with repeated rapid thermal changes, creating gaps between the panels and leading to leaks.
Moreover, impacts from things like branches falling on the roof following a storm can dent zinc roofing and compromise its integrity.
If you notice that your roof has become distorted in any way, you should consider replacing panels that may have been compromised before more significant repairs become necessary.
Fastener Failure
The fasteners that hold your zinc roof in place are essential for a secure roofing structure. Sadly, these fasteners are often the weak point of your zinc roof.
The most frequent places for rust and corrosion to appear are near the fasteners, which over time may cause them to become loose. Incorrect installation can also cause fasteners to become undone.
When fasteners fail, gaps might start to form between the panels and other parts of the roof, which could cause the roof to lift slightly, resulting in leaks. When water seeps in, internal damage to your roof structure may occur.
Fastener failure must be addressed as soon as possible in order to prevent significant portions of the roof from separating and exposing the interior structure.
