Turning roofs into smog-fighting surfaces

If you're a homeowner, the idea of replacing a roof might cause a little concern. We only do it once or twice in our lives and it costs some money. But what if in addition to protecting your home, your roof had the same smog-reducing power of 2-3 trees? Our guests tell us how incorporating some cool technology into an otherwise innocuous product has led to some good growth for the business and helped create clearer air for homeowners. Listen in to this shingle shakedown – it covers it all.

Guests: Carrie Niezgocki and Lara Ughetta, 3M Industrial Mineral Products Division
