Common Metal Roof Problems and Solutions

Metal roofing is a rising star in commercial and residential roofing — and industry surveys show that it’s now the second-largest income generator among roofers. It’s easy to see why. Metal roofing is extremely durable, energy-efficient, and strong enough to handle weather that other roofing materials can’t. It’s also fully recyclable.

Metal roofing isn’t, however, indestructible. Like any other type of commercial roof, it can run into problems that — if left unsolved — don’t just rob you of the advantages of metal roofing, but even put your building at risk.

Curious what they are? Let’s do a quick rundown. This list lets you know what to expect if you’re thinking about commercial metal roofing as an option for your building. If you already have a metal roof, it will help you take the first step toward fixing issues you might have with it.

1. Metal Roof Leaks

Commercial metal roofing is vulnerable to leaks — not just if it isn’t installed by a professional metal roofing company, but also as seams, sealants, and fasteners wear out over time. In snowy climates, ice dams are another common cause of leaks.

Solution

The solution starts at the beginning — with a quality installation. Research commercial roofing companies before you decide which is experienced enough for the all-important job of installing your commercial metal roofing.

If you already have a metal roof, commit to regular roof inspections. As your commercial metal roofing ages, ask your trusted roofers about installing a commercial roof coating to prevent leaks at your roof’s weakest spots.

2. Oil Canning

Excessively-stressed metal roofing panels can develop “waving” that risks causing further damage and is also unsightly. Although the exact culprit varies, human error during the roof installation process is almost always the root cause.

Solution

This problem highlights how important it is for a licensed, experienced, and reputable commercial metal roofing company that works with leading roofing manufacturers to do your commercial metal roofing installation.

3. Rust

Corrosion is another common issue any commercial roofing contractor who repairs commercial metal roofing will come across. Of course, most types of metal can rust, but corrosion only occurs in specific circumstances. Ponding water caused by faulty installations or lack of drainage is one common cause, but commercial metal roofing can also rust when it comes into contact with other metals.

Solution

Corroded metal roofing is vulnerable to punctures and leaks. If your metal roof has already exceeded its expected lifespan or the rust is extensive, it might be time to call a commercial roofing company for a roof replacement. If the issue is still localized, installing a better drainage system and considering a metal roof coating can add years to your roof.

4. Punctures

You might think you avoid the risk of punctures by opting for commercial metal roofing rather than TPO, EPDM, or other membrane roofing systems, but that’s not necessarily true. Debris colliding with your roof during extreme weather or people walking on your roof (especially with heavy objects) can both contribute.

Solution

Only let commercial roofing contractors on your roof if you can help it. If other professionals, like HVAC technicians, need access, make sure they understand how to look after your roof. Have nearby trees trimmed regularly.
