Therefore, I have listed the 7 most common metal roof installation mistakes and how to avoid them.

A list of the 7 Most Common Metal Roof Installation Mistakes to Avoid

1. Measurement errors

One of the most common mistakes in a metal roof installation is measurement errors. A simple mistake in measurement and marking can delay the entire process. So, it is important to double-check the measurements before ordering the panels. You also need to measure the panels upon arrival to give yourself a chance to report and correct any inaccuracies.

2. Choosing the wrong metal roofing panel

Choosing the wrong metal roofing panel is another common mistake. The market is full of different metal roof panels, all with different shapes, sizes, and profiles. In case you choose the incorrect metal roofing panels, common issues with delays and inconveniences can be reported. It is therefore important to confirm that the panels selected have a weather-tight fit and are correct for the pitch of the roof.

3. Choosing the wrong underlayment

Metal roofing is referred to as an installation system because there are many parts and tasks involved, and it’s not just the panels that make up the complete installation. The underlayment is also an essential component, and it comes in various brands, sizes, and shapes. Therefore, it’s crucial to choose the right underlayment to prevent issues with the home’s insulation, leakages, and potential damages.

4. Fastener issues

Many experts will confirm that the fasteners should be installed correctly otherwise you will experience leakages and other related future issues. They should neither be screwed too loosely nor too tightly as this can cause cracks or roof leaks. Incorrect fastener installation can also cause oil canning. Oil canning is a situation where the metal contracts or expands as temperature changes and makes the roof look wavy.

5. Improper roof plumbing

Another common issue with metal roof installation is ignoring the metal roof plumbing. Most people focus on the roofing material, and they forget other essential parts of roofing such as downpipes, spouts, or gutters. So, It’s good to have a plan for metal roof piping and plumbing to avoid future issues with leaks, corrosion, water damage, staining, and other related problems.

6. Incorrect sealant

Sealants are used during metal roof installation to keep off water and dirt. If this is done wrongly, the roof can be prone to leaks. There are some sealants specifically made for metal roofing. You should use this type of sealant because other types of sealant will not adhere to the pain on the panels.

7. Using the wrong supplies

During the metal roof installation, various supplies are required, including underlayment, panels, foam closures, trim and flashes, sealant, fasteners, and pipe flashing. In case you miss out on any of these, there are chances that you will have problems with leaks and other issues. Scratch all these issues, and call for the professionals for any roof asset management from next time.

Conclusion

Metal roofing is one of the best roofing options for homeowners who are looking for a long-lasting and durable roof. However, if you are a roofing contractor, it is important to remember the discussed mistakes when installing metal roofing for your clients to avoid any potential roofing issues.

If you are a homeowner, you should consider hiring an expert roofing contractor who can help install your metal roof perfectly.
