How the roof soft wash price calculator works

Soft washing a roof is usually priced per square foot of roof surface, but a good per-foot price comes from your real costs. This roof soft wash price calculator works from time, crew, chemical and margin and then shows the price per square foot.

A steeper roof has more surface area than its footprint, which is why the pitch factor is included. Access, height and safety equipment also change the time.

Examples only. Replace the speed and chemical cost with your own numbers from past jobs.

The formulas

Roof surface = footprint x pitch factor

Hours = roof surface / speed + setup and travel

Cost = hours x crew x wage + chemical + equipment

Price = cost / (1 – target margin %)
