A local roofing company has been highlighted in Time magazine's list of its top 50 inventions of the year.

Malarkey Roofing has been in Portland for more than 60 years.

All its roofing shingles are made with a substance that reduces smog.

Sunlight activates grains in the shingles, and then binds to air pollutants and breaks them down. Rain then washes away the smog.

The company making the grains is based in Minnesota, but Malarkey Roofing's role in using it in all of its shingles got it a mention in the Time magazine article.

"Personally, I'd like to think that sometime next year we will have removed as much smog as has been produced in moving our product to market anywhere in the country. And from there, after that, we're adding to the effort to clean the air," said Gregory Malarkey, senior vice president for Malarkey Roofing Products.

Malarkey Roofing already reduced an estimated 100,000 trees worth of smog. It hopes to double that amount every year.
