8 Common Problems That Could Seriously Damage Your Metal Roof

In recent years, metal roofs have been gaining popularity as a selected roofing solution due to its durability. Compared to shingles or clay roof tiles, the maintenance expenses for metal roof is relatively lower. 

Metal roof may be able to withstand extreme weather and climate conditions, but it is not completely damage-proof. When your metal roof has minor roof damage and left unattended, it can lead to major problems that could damage your metal roof permanently. This may cause serious issues to the insulation and structural components as well.

Here are some of the common problems that could cause serious damage to your metal roof. Each of these metal roof problems must not be ignored and should be inspected by a professional.

Metal roof problems that could lead to serious roof damage

  1. Surface Rust

Surface rust on metal panels are caused by the oxidation effect of wind, moisture and other elements in the air. New metal roof panels are coated with a layer of protective coating to prevent the formation of rust on the surface, but external factors can cause the protective layer to wear away over time.

Good rainwater flow capacity is a crucial characteristic of metal roof panels. This will lower the risk of surface rust that are due to prolonged water pools on the metal roof panels. Thung Hing’s TH PU Foam Ulroll Bond is a highly durable, weatherproof metal roofing material that has an anti-fungus and anti-rust protective layer. Other materials such as the TH Clip Lock Optima 730 is also protected with a layer of corrosion inhibitive treatment to prevent the formation of rust.

  1. Deflected Roof Panels

Metal roof panels may deflect or bend due to external impact. This may cause water to become stagnant and pond on the surface of the metal roof, causing leaks and rust. If ignored without proper repair, these leaks or rust may cause serious damage to your metal roof insulation and even roofing structure.

Thus it is important to choose high quality metal roofing that can withstand great impact. Consider TH PU Foam Deck 762 and TH Superior Rib 35 excellent metal roofing materials that has high durability, long spanning capacity and good waterflow capacity.

  1. Movement

A metal roof is designed to allow flexibility and movement, so that water will not pool on the roof surface, and will flow off of it. If the metal roof installation does not allow for proper elongation, stagnant water pools on its surface will cause problems that are more serious than the original roof leak.

  1. Incompatible Metals

There are many types of metal roofing materials, for example, copper, steel, stainless and galvanised metal. Some metals are incompatible when used together, and may cause negative reactions when in contact with each other. An experienced metal roofing provider should be well-informed on metal compatibility and can help you prevent such problems from happening.

  1. Punctures

Punctures rarely happen on metal roofs, but it can happen due to heavy foot traffic on the roof during construction or maintenance. Sharp impact falling onto the roof can also contribute to punctures in your metal roof, resulting in gaps or holes in your roof that may lead to water leaks.

  1. Fastener Issues

Metal roof panels are attached with clips and fasteners with rubber washers. Over time, these fasteners may come loose and back out of their originally installed position, leaving a hole in between the metal roof panels. This puts the metal roof at risk of water intrusions and may result in greater roof damage if not immediately rectified.

Thung Hing’s metal roof supplies such as the TH Clip Lock 710 is installed by concealed fixing method using clip and locking system. It is very secure when installed together, giving you peace of mind without worrying about loose rubber fastener issues. Besides, this concealed clip-lock method is also aesthetically pleasing.

  1. Open Laps

Open laps on metal roofs are usually caused by improper installation, causing the seams along the metal roof panels to lift up. When water intrudes the open area, it will ultimately cause structural damage to the metal roof.

Most of Thung Hing’s metal roof materials like the TH Clip Lock Optima 730 have long spanning capacity, thus minimising the issue of open laps between metal roof panels.

  1. Missing Parts

As the metal roof ages over time, pieces and parts of the roof may fall off due to deterioration and wind. Missing foam closures, edge metals, gutters and other parts can all lead to water intrusion and leaks, which will cause immense roof damage.

Engage Trusted Roofing Contractors to Repair Your Metal Roof 

Generally, metal roofs have a long service lifespan up to a few decades. Yet, this does not mean that it does not deteriorate or immune to damage. When you notice any unusual issues with your metal roof, you should always take immediate rectification action.

基于其坚固耐用性,金属屋顶近年越来越受民众欢迎。与木瓦或瓷砖屋面瓦相比,金属屋顶面板的维修维护费用相对较低。

虽然金属屋顶能够承受极端的天气和气候变化,但它并不是完全防损坏的。若您的不去理会金属屋顶的小损坏时,损坏情况可能会日益严重,导致更大的屋顶问题而对您的金属屋顶造成永久性的损坏。这也可能导致隔热层和结构部件的严重问题。

以下是可能会严重损坏您的金属屋顶的一些常见问题。这些问题中都不可忽视,应该尽快安排专业人员进行检查。

可能导致金属屋顶严重损坏的问题

  1. 表面生锈

疾风,湿气和空气中的其他元素都有可能造成金属屋顶面板表面氧化并锈蚀。新的金属屋顶面板都会涂盖一层保护涂层,以防止金属屋顶表面生锈,但是其他环境因素会导致保护层随着时间的流逝而被腐蚀。

良好的雨水排水性能是金属屋顶面板的关键特性。 这将降低金属屋顶面板因为长期积水而产生锈蚀的风险。 东兴集团的 TH PU Foam Ulroll Bond 是一种高度耐用,防风雨的金属屋顶建材,并具有抗菌和防锈保护层。 此外,TH Clip Lock Optima 730 也有覆盖一层防蚀保护层,以防止生锈。

  1. 变形的屋顶面板

金属屋顶面板可能会因为外部撞击而变形或弯曲。这会导致水积停滞在金属屋顶的表面,渐而锈蚀或漏水。如果这时不进行适当的维修工作,这些漏水或锈蚀可能会严重损坏您的金属屋顶隔热层,甚至影响屋顶的基础结构。

因此,选择坚固并能够承受巨大冲击的高质量金属屋面非常重要。 这种情况下可考虑 TH PU Foam Deck 762 TH Superior Rib 35 这两款优质的建材,它们具有高耐用性,长跨距能力和良好的雨水排水性能。

  1. 屋面板移动

金属屋顶的设计具有灵活性,因此,水不会积聚在屋顶表面上并且会自然地流走。如果金属屋顶安装不当,其表面将会出现积水的可能,导致比屋顶漏水更严重的问题。

  1. 不相容的金属

市面上有许多类型的金属屋面材料,例如,铜,钢,不锈钢和镀锌金属。某些金属不适合一并使用,当相互接触时可能会因金属性质不相容而产生不良反应。经验丰富的金属屋顶承包商应了解不同金属种类的兼容性,都会防止此类问题的发生。

  1. 金属屋顶遭穿刺

基本上,金属屋顶很少会发生穿刺问题,这情况可能会因屋顶建工或维护过程中,在屋顶上工作的人流过多,才会有可能发生。此外,重物跌落在屋顶上的剧烈撞击也可能会造成金属屋顶刺破,而导致屋顶生缝隙或洞孔,出现漏水问题。

  1. 紧固件问题

金属屋顶面板都用面板夹来固定,并用橡胶垫圈固定。随着时间的流逝,这些紧固件可能会松动移位,造成金属顶板之间留开了个孔。这会出现属屋顶临漏水的危机,如果不立即整修,可能会导致更严重的屋顶损坏。

东兴集团的金属屋顶建材,例如 TH Clip Lock 710,都使用带有夹锁系统的隐藏固定式方法安装的。金属屋顶面板牢固的安装在一起,无需担心像胶紧固件松动的问题。 此外,这种隐藏固定式的夹锁效果也赏心悦目的。

  1. 开叉孔

金属屋顶上的敞口通常是由安装不当而造成的,导致金属屋顶板上的接缝开叉。有水流入此开叉孔时,将会出现漏水现象,最终将损坏金属屋顶的基础结构。

东西集团提供的大多数金属屋顶建材,包括 TH Clip Lock Optima 730 都具有蛮长的跨距能力,从而大幅度减少了金属屋顶板之间会开裂问题。

  1. 屋顶零件缺失

随着金属屋顶的老化,屋顶的零件部分可能会因松动而掉落。这包括封盖,边缘金属零件,屋顶檐槽和其他部件缺失都可能导致漏水,和屋顶严重损坏的现象。

聘用信赖的屋顶承包商,修复您的金属屋顶

一般上,金属屋顶的使用寿命可长达几十年。但这并不意味着它不的情况不会腐蚀或损坏。当您发现金属屋顶有任何异常现象时,应立即采取修复措施。忽略较小的屋顶问题可能会导致更严重的后果,甚至影响建筑物的结构部件或损坏。
