What Affects the Cost of Roof Cleaning
Roof cleaning is priced mostly on the size and steepness of the roof, plus how heavy the algae, moss or lichen is.
Pitch and height
Steep or tall roofs need more safety setup and time. A low-pitch ranch roof can often be treated faster.
Growth type
Black streaks (Gloeocapsa magma algae) come off with a single soft wash application. Thick moss and lichen take longer dwell times and sometimes a follow-up treatment as they die and release.
Why it's worth comparing to replacement
Asphalt roofing manufacturers note that algae is mostly cosmetic, but moss holds moisture against shingles. Keeping growth off helps a roof reach its expected life.

What customers say
"First Class Cleaning washed our entire church building roof to ground. The building had built up quite a bit of algae and mildew over the years. It now looks brand new. The guys worked with our preschool and ministry schedule. They got the job done quickly and at a fair price."
