Oregon's East Multnomah Soil & Water Conservation District is re-roofing a historic building with tiles made of recycled rubber tires. When it is completed, the roof will be made up of materials from up to 1,000 tires. The rubber tiles have a higher insulation value than traditional shingles and are highly durable, experts say. Observers also note that more homeowners and businesses are interested in rubber roofs because the cost of traditional asphalt has increased.
