Titanium® PSU30 is the only modified rubberized asphalt Peel & Stick underlayment with a patented slip resistant Sure-Foot® nodular walking surface technology that allows for easier steep slope walkability, even in wet or dusty conditions. And it can be applied under most types of roofing shingles, including metal, tile, shake, slate, and both asphalt and synthetic shingles.

It is specifically designed for waterproofing protection on 2:12 or greater sloped roof applications subject to the effects of ice damming and wind driven rain.
Its unique cool gray surface technology does not expand or contract and provides for a cooler working surface during installations.
It’s a granular-free surface which can protect your metal roof from premature corrosion.
Titanium® comes with a Lifetime Limited Warranty*

Sure-Foot® Technology – the patented nodular walking surface creates safer walking conditions on steep slope applications • Cool Work Surface – the gray underlayment provides a cooler working surface during installation • High Temp – Titanium® is engineered to perform in temperatures up to 240° F • Durable – Resists tearing around nails and fasteners even in extreme conditions • Water / Vapor Barrier – Creates a second line of defense against water infiltration • UV Exposure – Excellent exposure can withstand the elements
