Roof Saver. Surround SR Underlayment is a waterproof synthetic polymer that’s 40 percent lighter than 30-pound roofing felt — as well as more durable and slip-resistant and less prone to tearing, says the maker. It’s unaffected by moisture and has a reflective surface that reduces heat buildup on the roof. According to the company, a 45.25-inch-by-267-foot roll covers 10 squares; the manufacturer declined to provide pricing. Fiberweb, 615/847-7000, surroundtypar.com

Water Break. The Delta Footing Barrier is a three-ply impermeable membrane that goes on top of freshly poured footings before the foundation is built. Its purpose is to prevent water from wicking up through the concrete and saturating the basement walls. According to the maker, the membrane is flexible enough to follow the contours of a keyway. It has an anti-slip surface, a polyethylene center, and a polyester needle-punched fabric bottom that sticks tightly to fresh concrete. It costs about $1.20 per square foot.

Sump Switch. LevelGuard is a submersible electronic sump pump switch designed to replace a mechanical float. Rated for up to 1?2-horsepower sump-pump applications, it mounts on the discharge pipe and sends power to the pump through a piggyback plug. It’s compatible with both new installations and retrofits but won’t work with an integrated switch pump system. According to the manufacturer, the switch will complete more than one million cycles without failure and last seven times as long as traditional float switches. It costs $130.

Filter and Softener. The Kenmore Elite Hybrid Water Softener does more than soften water and prevent scale buildup in fixtures and appliances.

Simplified Rough-In. The new GrohFlex universal valve system uses a one-size-fits-all rough-in box to serve a wide variety of tub and shower fixtures.

The rough-in box lists for $135; trims range from $160 to $475. Grohe America, 630/582-7711, groheamerica.com

High-Class Mud. R-777 Premier All Purpose Ready Mix Joint Compound may not be a household name, but its maker says it contains less air than better-known products and yields more working time with less tool drag. It also adheres well, shrinks very little, and works nicely with automatic taping tools, says the company.
