The Rotochopper Difference

One look at the RG-1 will tell you that it is different, from the outside to the inside, from the bottom to the top. But it’s not just a different design. It’s a whole different approach to recycling shingles. You see the difference where it matters most—your bottom line.


Lowest wear costs

Designed exclusively for the abrasiveness of asphalt shingles, the RG-1 dramatically reduces wear costs.

No routine hardfacing

Unlike typical wood grinders used for shingles, the RG-1 only requires hardfacing on select spots every few months.

Most uptime

With less wear and maintenance, you get more uptime and more recycled asphalt shingles (RAS).
