First Metal Roof Job Booked...
Permalink  
 


We are new to the roof washing business. Started about two weeks ago and 5 jobs now completed. The info here has been invaluable! Now...we just booked our first metal roof job. Two story house, about 2800 sq ft. We told the owner it will require a boom lift rental as metal roofs are just too slippery to get on. I could shoot it from the bottom but the roof has a very prominent ridge vent and we do NOT get water in attics due to mold...something which we know very well. Question is...the mix. Our initial plan is to use a 20% SH/surfactant mix versus the 40-60 mix we have been using ( it is the Pac Northwest and we have a LOT of Moss). However...I am wondering if just a heavy surfactant mix applied with our Fatboy pump pump followed by a heavy wash down would be just as effective? Would this be one area where a Percarbonate wash would be appropriate or is that another waste of time...yup, tried it on a test roof on a building on my property versus SH versus our regular commercial fungicide we use in mass quantities in our remediation division (killed the GM...didn't touch the Moss).

Kevin,

I`m new and live in Fl. We have lots of metal roofs which I have not had the chance to clean yet. How did your job come out and what solution did you use?

Hi Jim, I'll PM you with the info. Needless to say, the mix we ended up with worked beautifully and we have a happy customer. We did end up renting a boom lift. No way I was sending my top man onto a wet metal roof....take that into consideration when bidding.

Kevin, I've found that metal cleans up at a much lower percentage than asphalt. Time consuming part of metal is the rinsing...
