Residential metal roofing is becoming a thing of the future. Unlike traditional roofing, metal roofs are far more secure and long-lasting. They’re environmentally friendly, they help keep your house cooler, and they protect your house from disasters such as wildfires and lightning strikes.

For these reasons alone, switching to a metal roof can be a great decision. However, before you make a decision, you may be wondering how you’re supposed to install your new metal roof. Will you have to remove your entire roof before you replace it with your metal roof, or can a metal roof be placed over shingles? To get a better idea of the answer, let’s take a closer look at some factors that come into play during metal roof installation.

Preventing potential issues

Metal roofing comes with plenty of benefits. One of these benefits is increased cooling, due to a metal roof’s ability to vent air and reflect sunlight. Although having a metal roof seems like it would be a heavy inconvenience, since metal tends to be extremely heavy, metal roofing is actually very lightweight.

And what that lightweight materials means in terms of installation is that there’s no need to remove the shingles from your existing roof. The metal exterior will not add too much weight or cause any damage to the existing roof. These shingles will also help anchor your metal roof down onto your existing roof for additional support from the elements. Unless your old roof is damaged beyond repair and needs to be fixed before the new roof is installed, or unless you want to get rid of the current shingles, there is no need to remove the shingles before you place your metal roof over them.

In fact, if you choose to remove your shingles, you’re putting yourself at a higher risk of damage from the elements. That’s because a metal roof which is simply placed over a bare roof can contribute to water vapor build-up, which will eventually lead to the growth of mold and rotten wood over time. Of course, you can choose to do this as long as you take the necessary precautions and make sure that you get the right protection. For example, if you plan on placing a metal roof over your condo without the shingles, you should definitely purchase condo insurance in New Jersey.

If you’re looking to avoid damage to your roof — which might cause you to go through the process of repairing the roof and repeating the installation process all over again —  placing your metal roof directly over the shingles is the best way to go.

Building codes restrictions

This shouldn’t present too much of an issue, but it is important to note that some regulations in your area may prevent you from building your metal roof directly on top of your existing roof. These regulations generally limit you to only two layers of roofing on your house. Although there are some occasions where you can bypass these rules, keep this in mind when you consider installing a metal roof. If you install a roof and go against certain codes, you may end up having to remove your metal roof to dispose of the shingles anyway.

So, can a metal roof be placed over shingles? Absolutely! In fact, it is highly recommended that you do so, as it helps to enhance the overall efficiency of your metal roof. The only thing you have to keep track of is the laws in your area, so that you meet all building standards and requirements with your new metal roof. To make sure that the job is done right, hire a company specializing in metal roofs like Everdrain™ who can take care of the installation and ensure that your roof provides all of the above benefits and more for years to come.
