Titanium® X30 Synthetic Underlayment is a water and vapor barrier and therefore must be installed above a properly ventilated space(s). Follow all building codes applicable to your geographic region and structure type as it is considered a vapor barrier. Always follow safe roofing practices and OSHA safety requirements. Always wear and use fall protection devices when working on roofs. Use caution when walking or standing on Titanium® X30 in wet or dusty conditions that may reduce traction. Failure to use proper safety equipment and footwear can result in serious injury.


Deck Prep

Titanium® X30 should be applied to a properly prepared dry deck that is smooth, clean and free from any depressions, projections or protruding nails. Acceptable roof deck materials are minimum 6 inch roof deck boards, minimum 3/8 inch plywood, minimum 7/16 inch OSB, sheathing placed minimum 1/8 inch and maximum 1/4 inch. Roof decks should be structurally sound and meet or exceed minimum requirements of the roof deck manufacturer and local building codes.


Use

Titanium® X30 must be covered by primary roofing within 30 days of application. Titanium® X30 is designed for use under asphalt, metal, composite shingles and cedar shakes.


Application

Slopes from 4:12 and greater: Titanium® X30 is to be laid out horizontally (parallel) to the eaves with the printed side up. Horizontal laps should be 3 inches and vertical laps should be 6 inches and anchored approximately 1 inch from the edge. End laps in succeeding courses should be located at least 6 feet from the laps in the preceding course. Where the roof meets a wall, extend Titanium® X30 a minimum 4 inches up the wall.

Slopes 2:12 to less than 4:12: Cover the deck with 2 layers of Titanium® X30. Begin by fastening a 21-inch wide strip of Titanium® X30 along the eaves with the minimal fasteners needed to hold the course in place. Place a full-width sheet over the 21-inch course and overlap each successive course by 50% plus 1 1/2 inches. Additional fasteners may be required in high-wind regions per local building codes. Vertical lap requirements are the same as 4:12 and greater slopes. Titanium® X30 is not recommended for use on slopes less than 2:12 or on vertical surfaces such as walls.


Fasteners

4:12 to 12:12 for exposure up to three days: When excessive wind and rain is not expected, Titanium® X30 can be anchored with a minimum 3/8 inch crown staples, cap staples or corrosive resistant 3/8 inch diameter head x 1 inch long roofing nails (ring shank preferred, smooth leg acceptable), when covered with primary roofing within 3 days. Fasteners must be placed in the laps of the material and not in the field of the product. Roof pitches less than 4:12 need to be installed with cap nails. If Titanium® X30 will be not be covered within three days and up to 180 days, then product must be attached to the roof deck using a minimum 1-inch diameter plastic or metal cap nails (ring shank preferred, smooth leg acceptable). Miami-Dade approved tin tags/metal caps are also acceptable. For extended exposure, it is required that Titanium® X30 be anchored every 6 inches in the overlaps, and every 12 inches in the field. Consult local building codes for fastener type and spacing requirements.
