Abstract
Algae-resistant roofing granules are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores. Release of the algaecide is controlled by the structure of the granules.

Did this work, and how long does it last?

Unknown if it worked ?
All the roofing manufacturers use the 3M system instead of this.

Even with the 3M product they only guarantee it for up to 20 years max and that may be a 30-35 year shingle. Normal range is 5 to 15 years on the no algae warranty.

Probably most homeowners forget about no algae warranties after a few years, if they ever knew it had one.

Would this be our biggest competitor/ worst nightmare if they did this or do you think that people will opt out to save money in the long run?

I think these are the AR shingles. If so, I cleaned about 10 roofs with these shingles last season. They're a joke really. The AR stands for algae RESISTANT,...not proof. In my area it takes a typical new roof 3-5 years to start seeing the discoloration from the disease.

In that same 3-5 years with the AR shingles, the copper that is in the roof is washing away every time it rains, thus after 3-5 years the copper must be all gone,...and was in a sense working when it didn't matter anyhow. Hope I explained that properly so everyone understands.
