Roofing Washer

A roofing washer is an auxiliary fastener used together with self-tapping screws to secure layers of roof covering to the base, as well as on gables and parapets.

Roofing washers come as a flat or profiled disc with a hole for the screw. The outer edge of the disc has a pressure rim, and the center has a recess for the fastener head.

The material is zinc-plated or stainless steel. Some models are fitted with sealing gaskets made of weather-resistant rubber.

Using roofing washers provides the following advantages:

• watertight connection thanks to the EPDM rubber gasket;
• even distribution of load across the covering’s surface;
• preventing the roofing from being crushed or cut by the screw head;
• secure fastening of materials with different densities.

The range of roofing washers allows selecting fasteners suited to a specific type of covering and insulation material.
