Eliminate Algae Worries.

If you live in a wet climate, the consequences of dampness, humidity, and algae can be devastating for the appearance of your roof. PABCO® shingles with Algae Defender® offer protection from algae, preventing those nasty black streaks from forming on your roof. Test data has shown that with proper roof maintenance, Algae Defender is also effective in mitigating moss and lichen growth.

Our Algae Defender technology uses a precise, even distribution of copper granules on each shingle that is backed by years of data demonstrating superior performance. In coastal areas and other humid climates, Algae Defender provides another layer of protection, so you can worry less and enjoy your algae-free roof more.
