As a contractor, you know that a roof is only as strong as its weakest component. So why risk your reputation on felt paper?

It’s also lighter, easier to install and contributes to safe working conditions for your crew.

ProArmor® underlayment can withstand UV exposure up to 90 days and can be used under asphalt and metal roofing, so you have the time you need to get the job done right.
