Roof Systems

Since my relocation back to PNW, I have been forced to do about 70% roof services. We get heavy moss, not just algae streaks like Tennessee. I am not really enjoying the 12 volt system and looking for a more efficient option. Has a clear winner between a 1HP booster/generator vs Air Diaphragm system been decided here? I am looking for reliability as deliveries take a long time to receive and we have few local options for part replacement.

Air is the most reliable.
