GRACE ROOF DETAIL MEMBRANE

Self-adhered flexible flashing

Premium Protection at Roof

Detail Areas

Roof details, such as valleys, rake edges,

chimneys, ridges, skylights and dormer walls,

can greatly enhance the beauty of any home.

Unfortunately, they are also some of the most

leak-prone areas on a roof.

The results can range from stained walls and

ceilings to severe water damage, costing

thousands of dollars to repair. Unless the

leakage problem is corrected, damage will

continue to result.

Granular underlayments may lack the ability

to conform to many common roof details,

creating the potential for leaks. Grace Roof

Detail Membrane is a flexible product that

conforms tightly to these transition areas,

reducing the risk of water infiltration.

Grace Roof Detail Membrane is the only

product available today designed specifically

for waterproofing critical roof detail areas.

Product Description

Grace Roof Detail Membrane is a premier

membrane based on the Grace Ice & Water

Shield

technology. The new membrane has

the Ripcord

feature placed in the center and

near the edge (18 in. width) for easy installa-

tion at the transition areas as well as allowing

for future tie-ins. The membrane also features

square edge cuts and measure markings on

the face to further simplify layout and instal-

lation. The membrane is composed of two

waterproofing materials—an aggressive

rubberized asphalt adhesive backed by a layer

of high-density, cross-laminated polyethylene.

The rubberized asphalt surface is backed with

a release paper that protects its adhesive quality.

During application, the release paper is easily

removed, allowing the rubberized asphalt to

bond tightly to the roof deck and walls.

The membrane is available in 9 in. and 18 in.

widths. See the Product Data chart for more

information.

Features & Benefits Easy to handle and apply—The self-adhesive membrane bonds firmly to the substrate without heat or special adhesives. Water cannot seep under the membrane. Watertight seams are easily formed. Ripcord is a unique, patented feature that makes Grace Roof Detail Membrane easy to apply by giving the applicator a split release on demand. The split release makes positioning in detail areas easy by minimizing the amount of adhesive exposed during installation. Both the 9 in. and 18 in.
