It could be that it’s close to the airport, or it could just be that it hasn’t been cleaned for a long time, but in any case this metal roof in Marcoola was absolutely filthy, as you can plainly see in these before and after comparison photos. The gutters were filled with sludge and palm leaves. Using the Jetts surface cleaner and the Jetts pressure wand we cleaned the roof, gutters and solar panels. We think you’ll agree the results are quite amazing. The roof and gutters came up great.
