Abstract This invention discloses weatherable elastomeric and thermoplastic composite polymer films incorporating organometallic complexes for protection of exterior surfaces against the growth of dark colored algae. The process involves the surface reaction of water soluble polyvalent metallic salts with surfactants at reduced surface tension in the presence of film forming emulsion polymers. The lipophilic organometallic reaction products thus formed are encapsulated by polymer films with demonstrated exterior weathering durability in roof mastics and architectural coatings. By virtue of their vapor transmission, adhesion and elastic properties, the composite polymer films incorporating compatible algicidal organometallics extend both the life and appearance of exterior substrates.

Yep, with algeacidal properties. ALL we really need for long lasting roof treatments is ..... Well, SOME things will go "unanswered" until Dave and I MEET you guyz in Person !!
According to Dow's warranty "Damage to the shingles caused by alterations made after completion of application, including structural changes, equipment installation, painting, or the application of cleaning solutions, coatings, or other modifications;" If they think any damage was caused by this stuff, can they deny coverage?
I am wondering about some of these sealers and protective coatings after washing. Are they a good idea?

 If a company wants to "get out" of the warranty, they will find an excuse.
 Chris and what happens when they do have to cover the roof they pro rate it and you pay list price without labor , i went thought this 8 yrs ago with IKO shingles I went out and bought better shingles at a better price
