Ideal for use under metal including copper, zinc and COR-TEN® (consult technical department for installation instructions), WIP 300HT can also be used under synthetic tiles and asphalt shingles. This strong, skid-resistant membrane is available in either black or white and provides superior protection from water penetration caused by wind-driven rain and ice dams. Features and Beneﬁ ts • Protects the roof structure from water seepage caused by ice dams and wind-driven rains • Resists temperatures up to 250°F without degradation of the adhesive • Seals around rooﬁ ng nails, staples and screws • Bonds directly to the roof substrate for fast and easy installation without the need for additional adhesives • Split-release ﬁ lm provides easier, faster installation • Resists cracking, drying and rotting, providing long-term waterprooﬁ ng performance and low lifecycle cost • Concealed waterprooﬁ ng system will not detract from the architectural aesthetics of the primary rooﬁ ng system • Exposed rubberized asphalt bead along the membrane edge ensures watertightness of lap seams Standards • UL Classiﬁ ed • ICC-ES ESR #2206 • 2009 International Building Code™ • State of Florida Approved Product FSA# FL6782 • Meets ASTM D1970 Storage WIP 300HT rooﬁ ng underlayment rolls should be stored on end, under cover and in areas where the temperature is between 40° and 100°F (4.4° and 38°C).

Review the metal rooﬁ ng manufacturer’s instructions for limitations and precautions. Beginning at the eaves, apply underlayment from the low point to the high point of the roof, running the roll horizontally. Limitations • WIP 300HT should be installed when air, roof deck and membrane temperatures are at or above 40°F (4.4°C). • WIP 300HT should not be left exposed to sunlight for more than 60 days for black membrane or 120 days for white membrane. • WIP 300HT membrane should not be folded over the roof edge unless protected by a gutter or other ﬂ ashing materials. • The primary roof system must be ventilated to prevent excessive moisture build-up in the interior structure. • Use caution during the installation of the membrane as it may become slippery when wet or covered with frost. • WIP 300HT must not to be used in contact with ﬂ exible PVC material. Installation WIP 300HT underlayment is applied when the roof deck is dry and the substrate temperature is 40°F (4.4°C) or higher. At temperatures below 40°F, nailing or priming should be used to temporarily hold the membrane in place while adhesion develops. WIP 300HT is designed to be covered with the primary rooﬁ ng system and should not be exposed to sunlight for more than 60 days. White underlayment offers exposure time of 120 days. Moisture Substrate must be free of any moisture. If moisture is present, it may inhibit adhesion. New Construction Prepare the roof deck by removing all loose objects, dirt, dust and debris. Re-rooﬁ ng Remove all old materials from the roof deck in the area to be covered with WIP 300HT underlayment. Replace water-damaged sheathing and sweep roof deck thoroughly. Priming Priming is not required on clean, dry wood or metal surfaces but concrete masonry, exterior gypsum board and polyisocyanurate insulation should be primed using the appropriate primer or adhesive. Adhesives such as CCW-702 and CAV-GRIP™ are appropriate and required when temperatures are below 40°F. Valleys, Hips & Ridges Cut WIP 300HT rooﬁ ng underlayment into manageable lengths. Align over the center of the valley, hip or ridge. Remove release ﬁ lm. Press the middle of the membrane ﬁ rst before working toward the edges. For open valleys, cover WIP 300HT rooﬁ ng underlayment with metal valley liners. Eaves & Rakes Cut WIP 300 HT underlayment into 10–15' pieces. Remove 2–3' of release ﬁ lm and align the edge of the membrane, sticky side down, so it overhangs the drip edge by 3⁄8" (10 mm). Continue to remove release ﬁ lm and press as you move across the roof. Use a hand roller and/or hand pressure to press into place. Overlap end laps a minimum of 6". WIP rooﬁ ng underlayment should reach a point 2' inside the interior wall line. Local codes may require additional courses. If additional courses are required, the top lap must be at least 3½". Drip Edges At the rake edge, apply WIP 300HT underlayment ﬁ rst and place drip edge on top. At the eave, apply drip edge ﬁ rst and place WIP underlayment on top of the drip edge so that it overhangs drip edge by 3⁄8" (10 mm). For standard installation details, follow the WIP detail drawings. For non-standard installation instructions, contact your local Carlisle Residential representative.
