How Long Does a Metal Roof Last?

Lifespan considerations are naturally important for a variety of structural areas on our homes or buildings, and the roof is no exception here. Those looking for the most durable, longest-lasting roofs on the market tend to look to the realm of metal roofing first – precisely how long can you expect a metal roof to last, and which key factors influence this expected lifespan?

At Mid Michigan Metal Sales, we’re proud to offer a wide range of metal roofing panels, shingles, siding products and more to clients around Michigan, ensuring they have a fantastic roof that stands the test of time. Here are some basics on the typical averages for metal roof lifespan, plus the important variables that tend to impact this lifespan and how you can go about maximizing it for your metal roof.

Average Metal Roof Lifespans

While metal roofs are known to have the longest average lifespan of any common roofing material today, they also have a wide range of possibilities depending on several factors (which we’ll go over in a bit). Generally speaking, they can range from 40 to 70 years on average, with several variables influencing just where on this spectrum your roof falls.

Certain materials, such as copper, may last even longer – up to 100 years or more in some cases. However, these are often significantly more expensive and may not be a viable option for everyone.

Now, let’s get to some of the important factors that will influence exactly how long your metal roof will last for.

Local Weather

Naturally, the durability of your metal roof will depend in part on the climate in your specific area. Areas that experience harsher weather conditions, such as high winds, heavy rain or snowfall, and extreme temperature fluctuations, may see their roofs wear down faster than those with more mild climates.

This is why it’s important to consider investing in additional protective measures for your metal roof if you live in an area with severe weather events. These could include additional coatings, such as a rust-proof sealant, or ensuring proper installation techniques are used to minimize the risk of damage during extreme weather.

Proper Material Selection

There are several forms of metal roofing on the market today, and understanding which are best suited to your specific needs is important. For example, if you live in an area with high levels of precipitation or snowfall, choosing a metal roof with a steeper slope may help prevent water or snow buildup, protecting the longevity of your roof.

On the other hand, if you reside in a hurricane-prone area, investing in more durable materials that can withstand high winds and impact damage may be a better option.

Proper Installation

Like many other products, proper installation is crucial for a metal roof to reach its maximum lifespan. This includes not only the initial installation, but also regular maintenance and repairs. Improperly installed or damaged panels can significantly reduce the expected lifespan of your roof, so it’s important to work with an experienced roofing contractor who has expertise in metal roofing installations.

While we are not metal roof installers ourselves at Mid Michigan Metal Sales, we work regularly with contractors who are, and can provide recommendations for trusted professionals in your area.

Regular Maintenance

No matter how well-installed your metal roof is, regular maintenance is still crucial for ensuring its longevity. This includes cleaning off any debris that may accumulate on the surface, inspecting for any damage or wear and tear, and promptly repairing any issues that arise. Neglecting regular maintenance can lead to minor issues becoming major ones, which can significantly shorten the lifespan of your metal roof.

Pest Control

One particular element of roof maintenance that you may not have considered before is pest control. Pests such as rodents, birds, and insects can potentially cause damage to your roof, especially if they are able to make their way inside through any gaps or holes. Regularly inspecting for signs of pests and taking preventative measures, such as sealing any openings in the roof, can help extend the lifespan of your metal roof.

Birds, in particular, can cause damage to metal roofs by pecking at the surface or nesting underneath panels. Consider installing deterrents such as spikes, netting, or sound devices to keep birds away from your roof.

While there are several factors that can influence the lifespan of a metal roof, some key steps you can take include investing in extra protective measures for harsh weather conditions, choosing the right materials for your specific climate and needs, working with an experienced contractor for proper installation, performing regular maintenance, and taking preventative measures against pests. With these considerations in mind, you can ensure that your metal roof will last as long as possible and continue to protect your home or building for years to come.
