Sharkskin Ventilated Roof Mat®

IS SHARKSKIN® CONSIDERED HIGH TEMPERATURE UNDERLAYMENT

Sharkskin Comp®, Sharkskin Ultra® and Sharkskin Ultra SA® are high temp rated roof underlayments. All are polypropylene construction which has a 320 degree F melting point. Sharkskin Ultra SA® has as 280 degree F synthetic butyl adhesive. There is Zero asphalt in any Sharkskin Roof Underlayment.

HOW DOES SHARKSKIN COMPARE TO ORDINARY POLYMERIC ROOFING UNDERLAYMENTS?

The Sharkskin Roof Underlayment line of premium roof underlayments, are the heaviest most abrasion resistant line in the market. Most synthetic nail down roof underlayments are 22-30lbs per 10 SQ roll. Sharkskin Comp® is a 40lb 10 SQ roll, Sharkskin Ultra 50lb and Sharkskin Ultra Radiant is 55lbs. Sharkskin Ultra SA adhesive is 100 % solids no filler(limestone) like asphalt based adhesives

The Sharkskin Roof Underlayment line has done more extensive UV and Weathering testing than any other polymeric roof underlayment line in the market. Sharkskin Comp is 6 month UV and Sharkskin Ultra, Ultra SA and Sharkskin Ultra Radiant are 12 month.

Sharkskin Ultra SA has better overall temperature resistance, that includes the polypropylene substrate as well as the adhesive. This is why products like Carlisle WIP, Grace Ice and Water, and Grace Ultra, which all have thin film layer surfaces, can’t handle high heat or extended UV.

In addition to high temperature, Sharkskin Ultra SA can be installed at 10 degrees F and rising. Sharkskin adheres to metal, concrete, OSB, Plywood, Dendeck, etc. without primer.
