RhinoRoof® Anchor Sheet

RhinoRoof® Anchor Sheet is a mechanically attached bituminous anchor sheet designed for use in conjunction with self-adhered underlayment for high wind areas. RhinoRoof® Anchor Sheet is ideal for roofing recovers or applications where uplift performance is required but direct-to-deck installation of self-adhered underlayment is not preferred, or where it isn’t possible due to an existing layer of self-adhered underlayment that can’t be removed.

RhinoRoof® Anchor Sheet is a water and vapor barrier and therefore must be installed above a properly ventilated space. RhinoRoof® Anchor Sheet is not intended for and should not be used as a primary waterproofing membrane. Titanium® PSU30 or Owens Corning WeatherLock® Specialty Tile & Metal is required to be applied over the anchor sheet. 

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 RhinoRoof® Anchor Sheet in wet or dusty conditions that may reduce traction. Failure to use proper safety equipment and footwear can result in serious injury.

Follow all building codes applicable to your geographical region and structure type.

RhinoRoof® Anchor Sheet should be applied to a properly prepared dry deck that is smooth, clean, and free from any depressions, projections, or protruding nails. For roof decks with existing self-adhered underlayment, remove any loose portions and ensure the surface is smooth as possible and swept clean prior to installation. Acceptable roof deck materials are minimum 3/8 inch plywood, minimum 7/16-inch OSB, or minimum 6-inch roof deck boards. Roof decks should be structurally sound and meet or exceed minimum requirements of the roof deck manufacturer and local building codes.

RhinoRoof® Anchor Sheet must be covered within 60 days of application with either Owens Corning WeatherLock® Specialty Tile & Metal or Titanium® PSU30 self-adhered underlayment, as approved by the local building official having jurisdiction in accordance with the local product approval. RhinoRoof® Anchor Sheet is designed for use under clay or concrete tile but may be used with asphalt or synthetic shingles, metal panels or shingles, and cedar shakes that have been primed.

Slopes from 2:12 and higher: RhinoRoof® Anchor Sheet is to be installed horizontally (parallel) to the eave with the printed side up. Horizontal laps should be 3 inches and vertical laps should be 6 inches. End laps in a succeeding course should be located at least 6 feet from laps in the preceding course. The perimeter course of RhinoRoof® Anchor Sheet should be cut to ensure offset head laps from the cap sheet. At valleys, RhinoRoof® Anchor Sheet shall be either woven, extending through the valley line, or center cut. Metal flashings shall be nailed in accordance with local code requirements and primed with an ASTM D41 primer prior to cap sheet installation. 

Slopes less than 2:12: RhinoRoof® Anchor Sheet is not recommended for use. 

RhinoRoof® Anchor Sheet shall be mechanically fastened to the deck using fasteners and fastening patterns, as approved by the local building official having jurisdiction in accordance with the local product approval (if applicable) and the table below. All anchoring nails and plates must be flush and tight against the underlayment surface and the structural roof deck. For best results, fasteners should be installed in a staggered pattern. Avoid walking on RhinoRoof® Anchor Sheet until sufficiently attached to the deck for safety. 

Following mechanical fastening of RhinoRoof® Anchor Sheet to the roof deck, cover with Owens Corning WeatherLock® Specialty Tile & Metal or Titanium® PSU30 self-adhered underlayment within 60 days, following the installation guidelines for the underlayment being utilized.
