Metal Roofing Installation Mistakes You Should Avoid

If you have water leaking from the ceiling or if your roofs are taking away from the overall look of your home, it might be time to consider installing a new roofing system. As you do your homework about different roofing materials, you probably have come across metal roofing.

Metal roof is indeed a good choice because it offers a lot of benefits that other roofing materials like tiles do not provide. That said, it’s still crucial that the installation be done correctly because the roof system’s performance depends a lot on how well the roof was installed, too:

Making Errors in Measurement

Any error in measurement can mean days or even weeks of delay in the installation process. That’s why roofing measurement must be done correctly from the very beginning, during the planning process, and then double-checked before ordering roofing panels. It’s also important to measure the panels as soon as they arrive on-site so that any inaccuracies can be immediately addressed. The last thing you want is to find that there are measurement errors after or during the installation.

Choosing the Wrong Underlayment

The reason it’s called a roofing system is that it’s exactly what it is – a system that is composed of different parts. It’s not just the metal panels themselves that make up your roof. One of the most important parts of the roofing system is the underlayment.

If a roofer is inexperienced with metal roofing, they might not know which type and brand of underlayment work best for metal roofs. This is very important because it will affect your home’s insulation and protect it from any leaks and potential damages. You want to make sure that you’re working with seasoned roofers and that they specialize in metal roofing as well, so you won’t experience this problem.

Incorrect Fastener Installation

The fasteners used for your roofing have to be installed correctly, or you’re going to encounter troubles in the future. Whether the fastening systems are screwed too tightly or too loosely, problems like cracks and roof leaks could occur.

In other instances, incorrect fastener installation causes “oil canning.” This is when metal contracts and expands with heat that eventually makes your roof look wavy. This is more obvious with roofs with flat panels.

Improper installation of roof fasteners is usually a problem caused by new or careless roofers who may not be aware of the repercussions of this mistake.

Ignoring Roof Plumbing

When you’re getting your roof replaced, it’s easy to just be focused on the roofing material – the brand, the color, and the style that you tend to forget about other essential parts of your roofing system like its plumbing.

You need to think about the gutters, downpipes, and spouts because all these together protect your property from corrosion, water damage, leaks, staining, and more.

When your roof’s plumbing is not designed correctly, it might not be able to handle heavy rainfall or snow. This could translate to costly repairs in the future.


These are some common mistakes that should be avoided at all costs when installing metal roofs. By ensuring that measurement is done right, the underlayment is the correct type, the fasteners are installed properly, and the plumbing system is designed properly, you can avoid roof leak repairs and other costly services for years.
