Metal roofing is a high-end, durable, and long-lasting product that can often exceed (sometimes drastically) the life of roofing systems such as asphalt shingles or wood shakes. However, metal roofs can still fail, and it's not entirely uncommon for a metal roof to fail long before its expected lifespan. Why does this happen, and what can you do if your roof shows signs of failure?
In many cases, it may be possible to repair a metal roof showing early indications of trouble. However, some problems may be unrepairable, or it may simply be more cost-effective to replace the roof. If your roof is showing any of these three issues, it's time to consult a metal roofing expert to determine if you need a new metal roof.
1. Widespread Rust
Metal roofs typically use highly corrosion-resistant materials, but that doesn't mean that these roofing panels are rust-proof. Various conditions can accelerate the presence of rust on a metal roof, including damage, poor installation, loose fasteners, leaks, and drainage issues. Anything that allows moisture to pool or dry slowly can increase the likelihood of rust on your roof.
Once the problem becomes widespread, it's unlikely to be cost-effective to address particular rusted areas or to replace affected panels. It's also important to determine why the roof is rusting prematurely and address the underlying problem, which may require much more significant work. In many cases, widespread rusting is a sign that your metal roof requires replacement.
2. Underlying Structural Issues
Underlying structural issues are a problem on any roof. Common signs of structural problems may include sagging, popping fasteners, loose panels, or unusual sounds such as popping or creaking. There are many reasons that roofs can develop structural issues, from poor original installation work to physical damage and rot from persistent water leaks.
While it may be possible to address some structural issues through methods such as reinforcements, others will often require a complete teardown and replacement. If you notice problems like this on your roof, it's important to have a metal roofing expert inspect the issue as soon as possible. Ignoring the problem for too long may lead to severe leaks or other issues that can affect your whole home.
3. Severe Water Damage
Severe water damage, often caused by failing to address leaks for many years, can affect your roof's decking and cause the metal panels to loosen or weaken. These problems can ruin your roof, even if the panels look relatively intact and rust-free from the ground. The longer water issues go unaddressed, the greater the likelihood that your roof will require a premature replacement.
As with other problems, it's important to work with an expert to assess the extent of the damage and determine your options. If the roof appears too severely damaged to repair, a replacement will ultimately be a more cost-effective solution to ensure your home remains protected from the elements.
