Does Metal Roofing Underlayment?
Metal roofing needs underlayment because it provides a protective barrier that helps prevent water infiltration, protects against wind-driven rain, and acts as a secondary layer of protection in case the metal roofing is damaged. It also helps to reduce noise from rain and hail, and can improve the overall energy efficiency of the building. Overall, underlayment is an important component of a metal roofing system that helps ensure its long-term performance and durability.
When it comes to getting a new metal roof installed, there are several important decisions to consider. Some of these decisions include choosing the type of panel, selecting the metal gauge, and deciding on the color of the roof. We understand that this can be overwhelming, but we are here to help guide you through the process.
When making decisions about metal roofing, it’s important to remember the significance of using underlayment. This often overlooked component is actually a crucial part of a metal roofing system. While some may choose to skip underlayment to cut costs, it actually serves as an extra layer of protection and can ultimately save you money by preventing future problems that would require costly repairs.
Yes, your metal roof does require underlayment. However, the process is not as straightforward as it may seem.

The Advantages of Using Underlayment
When You Need Underlayment
When You Might Not Need Underlayment
What is Metal Roofing Underlayment
The roofing underlayment is a water-resistant barrier that provides an added layer of protection against the elements. Once the metal roofing material is installed on top, the underlayment is not visible as it is directly installed onto the roof deck.
Roofing underlayment has many benefits:
Added insulation
Noise barrier
Even surface for roofing
Building code compliance
Extra Protection
Roofing Underlayment Provides Added Insulation
Underlayment serves as an additional insulating layer for a metal roof, reducing heat absorption in hot weather and minimizing heat loss in the winter. This added insulation will help maintain a comfortable temperature in your home during extreme weather conditions, leading to more stable heating and cooling bills.
Roofing Underlayment Is A Noise Barrier
The roofing underlayment serves as a sound-blocker for a metal roof, providing an extra layer between the elements and the roof deck. This helps absorb some of the noise from rain or other elements hitting the roof, resulting in a more soothing experience for many people. While you’ll still be able to hear the rain hitting the roof, the outside elements will not be as loud or overwhelming as they would be without underlayment.
Roofing Underlayment Provides An Even Surface For Roofing
In some cases, roof decking may not lay perfectly flat. If you were to install a metal roof directly onto this uneven surface, it would result in an uneven appearance. However, by using underlayment, you can ensure a level surface for laying roofing materials, resulting in a uniform and aesthetically pleasing roof.
You Need Roof Underlayment For Build Code Compliance
Certain building codes mandate the use of underlayment for metal roofing. Additionally, the code may specify the specific type of underlayment to be used, such as felt underlayment or synthetic underlayment.
It’s important to be aware that certain material warranties require the use of synthetic underlayment. As a result, not using underlayment will void your warranty.
Roof Underlayment Provides Extra Protection
During severe weather, underlayment serves as an additional layer of protection for a metal roof. It helps prevent blowoffs or water penetration through the roof covering or flashings, ultimately shielding the inside of your home from direct exposure to the elements.
When You Need Roofing Underlayment
If you’re building a new home and your metal roof won’t be installed right away, it’s important to use synthetic underlayment. This material can be left exposed for anywhere from 2 to 30 months, depending on the brand, and will still protect your home from water damage. It’s designed to withstand exposure to the elements without being damaged, and its moisture-resistant properties prevent it from wrinkling and compromising the appearance of your metal roof.
It’s important to consider the slope of your roof when installing metal panels. A low-sloped roof can pose a higher risk for water damage, especially in areas with heavy rainfall. This is because the low slope doesn’t allow water to run off as quickly as higher-pitched roofing, potentially leading to leaks. To mitigate this risk, underlayment should be used as an extra layer of protection against water damage.
When You Might Not Need Roofing Underlayment
Underlayment is typically recommended, but it may not be necessary in certain situations. For instance, a covered patio with open beam architecture and panels that attach directly to the beams without sheathing does not require underlayment.
If you’re replacing a roof with metal roofing panels over an asphalt shingle roof, you may not need to use underlayment because the asphalt roof already has it. However, it’s important to consider the condition of the underlayment – it may be in poor condition. Even though only the asphalt shingles are visible, there could be underlying issues. To prevent future problems, it’s advisable to inspect the old roof to determine if it should be removed before installing the new metal roof.
Why You Should Use Roof Underlayment?
Underlayment is an essential component of a metal roofing system, providing protection against moisture, adding insulation, absorbing noise, and ensuring the roofing material is laid evenly. It also helps keep your roofing warranty valid.
