Hello from Australia
I have a commercial window cleaning business and one of my clients has asked to quote to pressure wash the roof of the building. The roof is pretty flat with on a gradual slope for the water run off. Most of the badly affected areas have just a build up of leaves. The area is approx 3500 square metres or 37500 sq feet.
I have a few questions that I hope I can get answered in this forum.
1.Can you please give me a rough cost or an average cost per sq m or sq foot
2.Is it advisable to remove all of the loose debris first or just pressure wash it off
3.If I am just removing mainly light algae growth in other areas is just a cold water pressure washer suffiecent
Any other advice would be much appreciated.
Thanks
