Information for St. Louis, MO Homeowners: Replacing an Asphalt Shingle Roof with a Metal Roof

Many Missouri homeowners know that metal roofs offer superior value and durability compared to traditional asphalt or other roofing materials. Because of the many benefits associated with metal roofing, you may want to install a metal roof, but don’t know how the process works. Here is a primer for anyone considering a metal roof, as well as answers to common questions.

Can I Put Metal Shingles Over Existing Ones?

You might be tempted to save on labor costs by simply putting metal shingles over the existing ones. Unfortunately, the process isn’t so simple. As asphalt shingles reach the end of their lifespan, they start to degrade and might let water into the decking underneath. Putting metal shingles over the existing asphalt ones may only trap water in your roof and lead to rot. In order to preserve the integrity of your roof, it’s essential to strip the shingles off, identify any wood rot, replace water-damaged decking, and put the new metal roofing material on to ensure your roof stays dry, no matter the weather condition.

Is the Cost of Ownership More Expensive for Metal Roofs?

Some people shy away from metal roofing materials because it represents a larger upfront investment. While a metal roof may cost more than an asphalt version to install, it proves to be a better investment when it comes to longevity and durability. With an asphalt roof, you may have to routinely replace shingles after storms or high winds. Because of metal roofing’s extreme durability, it requires little to no maintenance. When you install a metal roof, it might be the last roof you ever have to place on your home – that’s how long they last! On average, expect a metal roof to last 3 times as long as an asphalt version.

What Is the Warranty Like?

The other nice thing about metal roofs is they have a much longer than standard warranty. In fact, many metal manufacturers offer a warranty of 50 years on parts. This means you can enjoy more security in your investment and get help with any issues, should they ever occur.

Here’s the bottom line: metal roofs offer superior benefits over their traditional asphalt counterparts. While you can expect to pay a little more for the initial installation of your metal roof, it will pay for itself over a lifetime of energy efficiency and durability. For this reason, many homeowners choose to replace their aging asphalt roofs with a metal version.
