Shoveling snow is for the birds. Smart home buyers opt for snow-melting products that do the work. The Snow Melt mat, for example, can be installed under asphalt, concrete, or pavers to melt snow and prevent ice from forming. Mats measure 24 inches wide and maintain a temperature just above 32 degrees F.  Cost: less than $1,200 for a 50-square-foot driveway. Warmup Inc. 888-927-6333.
