A cost-effective snap-on coping system designed for use with single ply, built-up and modified bitumen roofing systems. The system consists of galvanized steel anchor clips and aluminum or galvanized coping covers in a variety of thicknesses and colors.
Presto-Tite Edge One Fascia System
Edge One Fascia system offers convenience and economical pricing to simplify projects and maximize profits. Our Edge One Fascia for single-ply roofs helps to protect the roof system against high wind events, saving the building from costly damage. The design eliminates the stripping in typical of other products, making Edge One Fascia fast and easy to install.
Presto-Tite Fascia System (Bituminous Systems)
A high performance edge treatment for all modified bitumen and BUR roof projects. Nonpenetrating design allows for vertical face attachment without penetrating the horizontal flange, and eliminates the need to strip-in the deck flange, eliminating potential delamination between the asphalt and metal deck flange due to thermal expansion and contraction forces. Provides maximum protection against wind uplift damage.
Presto-Tite Fascia System (Single Ply Systems)
A high performance edge treatment for fully adhered or mechanically fastened single ply roof projects. Nonpenetrating design allows for vertical face attachment without penetrating the horizontal flange, and eliminates the need to strip-in the deck flange, eliminating potential delamination between the adhesive and metal deck flange due to thermal expansion and contraction forces. Provides maximum protection against wind uplift damage.
Presto-Weld Drip Edge
Presto-Weld drip edge is a factory-fabricated coated metal edge system used to terminate at the perimeter of a PVC or TPO membrane. This edge comes with a factory applied, 8" wide PVC flashing strip or 6" wide TPO flashing strip of Johns Manville membrane to help save labor installation costs in the field. Presto-Weld is an economical solution for many conditions such as continuous edge drainage with or without a gutter condition.
