1. Classification
ROOF COVERING AND ROOF DECK CONSTRUCTION Underlayment SHINGLES, ROOF TILES AND ROOF COVERINGS 07300
2. PRODUCT NAME
SHARKSKIN ULTRA
3. Product Description
SHARKSKIN ULTRA is 100% polypropylene based, 12 month UV exposure rating, thermally stable
with an average melting point of 320 degrees F., a high tensile strength reinforced roof Underlayment used on steep slopes with battened tile applications, metal, real and synthetic slate, and asphalt composition shingles. SHARKSKIN ULTRA is a matt white color which keeps the building cool inside and out and is easy to handle in extreme heat. SHARKSKIN ULTRA incorporates our patented technology to create SHARK GRIP the most slip resistant wet dry or dusty roof Underlayment on the market to protect all trades while working on the roof. SHARKSKIN ULTRA has the highest tensile strength of any nail able polymer steep pitched Underlayment SHARKSKIN ULTRA can be left exposed for up to 12 months and contains anti-oxidants for long-term reliability. SHARKSKIN ULTRA is completely rot proof, will not expand and contract and wrinkle from high and low temperatures changes or moisture like Type 15 or Type 30 organic asphalt felts. SHARKSKIN ULTRA will not scar or melt like fiberglass SBS Underlayments at high temperature or crack at low temperature like asphalt based felts and Underlayments. SHARKSKIN ULTRA has been approved as an alternate replacement for Type 15 and Type 30 asphalt roofing felt, exceeds ASTM D226 per RADCO Test Report #3085, passed ICBO Acceptance Criteria for Roof Underlayments AC188 November 2001 and can be used as an Ice and Water Membrane per ICC ESR Report 1708.
4. SHARKSKIN ULTRA - Applications
For use under Tile installed over battened or counter battened systems, Metal roofing, Slate (real and synthetic), and Composition shingles.
5. SHARKSKIN ULTRA approval criteria:
ASTM D226 per RADCO REPORT# 3085, International Code Council (ICC) ES ER, ASTM E-84 Class A Flame Spread, ASTM E-108 Class A Fire underneath Fiberglass Shingles. All testing per ICBO AC 188 "Acceptance Criteria for Roof Underlayments" per Intertek Testing Services, Inc., passed.

7. Installation
SHARKSKIN ULTRA Underlayment is installed with a 4" horizontal overlap and 12" vertical lap. The Underlayment is laid horizontally (parallel) to the eave with the printed slip resistant side up, and is fastened using 3/8" head roofing nails, galvanized 1" round top nails, and or 1" plastic cap nails with galvanized shanks spaced at 12" on center on horizontal and 6" vertical laps. Reduce nail spacing in areas of high wind driven rain as needed. When installed beneath battened tile installations nail Underlayment as needed to provide secure and safe footing for the installer and other trades immediately prior to batten installation. A rosin slip-sheet is not required over SHARKSKIN ULTRA with metal roof systems. The use of peal and stick tapes is suggested to seal Sharskin Ultra TileTM as needed. SHARKSKIN ULTRATM is UV resistant for 12 months.
