Ready to Extend Your Roof's Life?

Roof Maxx can help you get 5–15 more years out of your roof with our proven plant-based treatment. If your shingles are still in decent shape, rejuvenation could save you thousands on early replacement. Here’s how it works:

Roof Maxx penetrates deep into your asphalt shingles to replace the oils they naturally lose over time.
This increases the flexibility of your shingles and prevents granule loss, making them more durable.
Roof Maxx also contains a natural fungicide that helps prevent new mold, mildew, and algae growth.

Best of all? A Roof Maxx treatment costs up to 80% less than the price of replacing your roof—so you can keep your home protected while also protecting your bank account.
