At the International Roofing Expo next week, manufacturer Propex will unveil Opus Roof Blanket, a synthetic steep-slope roofing underlayment the company says improves on the drawbacks that have made some contractors reluctant to give up felt.
We got a chance to preview the product and, at first glance, it’s easy to see how the product differs from other synthetics: rather than a plastic-like sheen, the tan-colored Opus feels more like a matte woven fabric on the working surface—almost reminiscent of some housewraps—backed by a woven plastic. The result is a material that is more slip resistant than both synthetics and felts, the company says, yet can remain exposed to UV rays for up to six months. Unlike roofing felt, the material is durable enough to be walked on, plus it stays cool in the summer, is lightweight, and can be marked with a chalk line or pencil. Opus installs with staples or nails, but requires caps if left exposed.
Like other synthetics, Opus will cost about twice as much as traditional felt, but the manufacturer says its faster installation (due to greater coverage per roll), ability to be left exposed, and its durability in the event of shingle tear-off, help negate those costs.
