Product Information


Titanium UDL-50 is an underlayment that provides a commercial grade level protection from air, water, and vapors. This underlayment can be applied to all kinds of roofs, including: metal, clay, slate, concrete tiles, and even heavyweight laminated asphalt shingles. UDL50 is 100% synthetic, therefore totally unaffected by water, which means it is 100% inert to mold, lays flat, will not wrinkle and you can leave your roof uncovered without the need for tarps or immediate dry-in. Unlike felts, UDL50 does not dry out, leach oils in the heat, nor does it become stiff, difficult to roll or crack in the cold.

Titanium UDL50 must be covered by primary roofing within 180 days of application. To install, make sure the deck surface is dry and free of any debris. For slopes 2:12 and higher UDL50 is to be laid out horizontally (parallel) to the eave with the printed side up. The use of a roofing hammer, hatchet hammer, pneumatic air or gas driven fastener tool is acceptable. For more specific directions, please see Installation Instructions below.
