In Your Opinion, Waht Is The Best 12v Pump for roof cleaning?

Get a Pressure washer instead.
 
Not for cleaning roofs! The delavan 5800 is a good pump to start. Also the everflow 7000 would be the next step up. No matter what pump u get they will eventually fail. Always have a back up and always rinse the pump out at the end of the day.
 
And when Mike says rinse, he means a minimum of 5 gallons of water,.with 10 being better. SH is slippery and it takes a good flushing to remove all traces from the inside of pumps, hoses and reels.

* Run your rinse water right back into the mix tank and get it ready for the next round.

I use to have a customer called New Shake Roofing. He applied his chemicals with a TS2021 Pump at Low Pressure 500 PSI and 5.6 GPM. Worked Great for 20 years.
 
I'm on my second delavan 5800.. first one lasted me about 6 months.. make sure you've got an accumulator. AND flush it when done!.. I Let mine flush/free flow with fresh water for 10-15 mins after a job, while I'm cleaning everything else up

Not for asphalt roof cleaning. Trust me when I say you need a dedicated pump for roof cleaning. Also it is alot cheaper than buying a pressure washer.

Must have been cleaning "new shakes",..as his name implies. Unless he was using the TS2021 as a direct applicator or maybe upstreaming,..(Which I know very little about percentages)

There's no way he was doing it by DS'ing,...unless he was pressure washing the shingles afterwards,...then that takes him out of the conversation altogether where roof cleaning is concerned on this board.

*For anyone concerned, using a pump like a TS2021 to apply roof mix is BAD advise no matter which way it was utilized.

We've got 2 of Bob's Fat Boys. One lasted maybe 2 months, but Bob shipped a new one out for free, however the accumulator busted a few days later. Replaced it and it's still going strong almost a year later. Our second one lasted about 6 months, replaced it and it's been fine for about 5 months.
