When you decide to install a durable, long-lasting metal roof to add superior waterproofing, fire resistance, and value to your Knoxville home, you’ll need to make a variety of choices regarding your roof’s appearance, including color, panel type, gauge, and more. However, one aspect of your metal roofing system you may have overlooked is the roof’s underlayment – the water-resistant material installed between your metal roof and the roof deck below. Underlayment can take many forms but is always a relatively thin, flexible layer designed to enhance your roof’s protective capabilities.
This additional layer is required in most building codes, and some even specify which type of underlayment must be used. In addition, some roofing types require the use of underlayment to ensure warranty protection – if you choose not to use underlayment in these situations, your roof’s warranty may be void. Even if your municipality or warranty provisions do not specifically require underlayment, we recommend its use for the multiple benefits it can bring to your roof.
