Roof Cleaning in Orlando: What the Service Involves
This page explains what professional roof cleaning in Orlando actually includes — the method, the sequence, what gets protected, and how it differs from pressure washing a driveway. If you already know you want a price, skip straight to the roof details form; if you want to understand what you are buying first, read on.
Roof cleaning is chemistry, not pressure
A driveway gets clean because pressure physically blasts grime off concrete. A roof cannot be treated that way: shingles shed their protective granules under high pressure, and tile cracks. Professional roof cleaning inverts the formula — very low pressure, with a cleaning solution (typically sodium hypochlorite blended with surfactants) that kills algae, moss, mildew, and lichen at the organism level. The growth dies, releases, and rinses or weathers away. Shingle manufacturers and their trade association endorse exactly this low-pressure, bleach-based approach; high-pressure washing, by contrast, can void shingle warranties.
The sequence on cleaning day
The work runs in a consistent order. First, protection: landscaping under the rooflines gets pre-wet and covered where needed, gutters and downspout paths are accounted for, and anything sensitive near the runoff line is flagged. Second, application: the solution goes on at low pressure, slope by slope, with dwell time for the chemistry to work. Third, rinse and neutralize: plants get rinsed again, walkways get washed down, and the roof is left to finish on its own — heavy lichen and moss may take some weeks to fully release after treatment, which is normal and worth knowing in advance.
What it does not include
Roof cleaning is not roof repair. If the inspection-level look at your roof shows lifted shingles, cracked tiles, exposed underlayment, or flashing problems, the honest move is to tell you before cleaning — chemistry will not fix mechanical damage, and cleaning a failing roof wastes your money. Roof cleaning is also not painting or sealing; tile sealing is a separate decision some owners make afterward, with its own tradeoffs.
When to clean
The practical answer: when growth is visible, and ideally before an HOA letter forces the schedule. Algae spreads from the first streak, moss and lichen hold moisture against the roof surface, and all three get harder to remove the longer they establish. Most Central Florida roofs settle into a cleaning cycle of every few years — sooner under heavy oak shade, longer on open sunny lots.

Frequently asked questions
How long does a roof cleaning take?
Most single-family homes are a same-visit job — a few hours depending on roof size, growth severity, and how much landscaping protection the lot needs. Heavy moss and lichen may keep releasing for weeks after treatment, which is the chemistry finishing its work.
Do I need to be home?
Usually not, as long as exterior water access and gates are available and pets are inside. Confirm the specifics when scheduling.
Will it smell like bleach?
There is a pool-chlorine smell during the work that dissipates quickly. Windows near the roofline should stay closed during application.
Is roof cleaning worth it on an older roof?
Often yes — removing moss and lichen stops growth that actively holds moisture against the surface. But if the roof is near replacement, an honest company says so before taking your money. Ask directly how much life the roof appears to have.
