Roof cleaning in Fort Lauderdale starts with one fact: those black streaks running down your tile are alive. Between the salt air off the Atlantic, the humidity off the Intracoastal and the shade from mature trees, Fort Lauderdale roofs give algae everything it wants. We remove it with a low-pressure soft wash that kills the growth at the source and leaves the tile intact.
What the Black Streaks on Your Roof Actually Are
The dark stripes and green-black patches are a hardy algae called Gloeocapsa magma, often joined by mildew and lichen. It feeds on the porous surface of cement and clay tile and on the limestone filler in asphalt shingles. It spreads fastest on the slopes that get the least direct sun.
Because it is a living colony, a hard spray only knocks the top layer loose and leaves the rest to regrow. Left alone, it keeps spreading, shortens the life of the roof and makes a well-kept home look neglected from the street. The fix is to kill it, not move it around.
Why We Never Pressure Wash a Fort Lauderdale Roof
High pressure on a roof does real damage. It can crack cement and clay tile, dislodge ridge caps, blow the protective granules off shingles and drive water under the flashing into the underlayment. On a tile roof that is already weathered by salt air, that risk is not worth taking.
So every roof we clean gets a soft wash: a measured cleaning solution applied at low pressure, given time to work, then rinsed with clean water. Tile, shingle and metal roofs each get their own mix and dwell time, because one recipe for every roof is how roofs get hurt.

How a Roof Soft Wash Works, Step by Step
We start with a walk around the house to spot fragile landscaping and weak points on the roof, like cracked tiles, missing pieces or compromised flashing. Anything that looks like it needs repair is documented and discussed with you before we begin. Then we pre-rinse the plants and sod along the drip line so runoff does not sit on them.
The solution goes on from the eaves up, which keeps streak patterns from forming as it flows down a wet surface. After the right dwell time, we rinse at low pressure and flush the gutters so dead algae does not collect inside them. A final clean-water rinse of the landscaping and a before-and-after walkthrough with you finish the job.
A typical single-story home of 2,000-3,000 sq ft takes about 2-3 hours. Larger, multi-story homes and roofs with heavy growth take longer. You can read more about our full method on the roof cleaning service page.
Tile Roofs Across Fort Lauderdale's Neighborhoods
The waterfront estates on Las Olas Isles, Rio Vista and Idlewyld usually carry tile roofs that face constant salt air. That exposure is why coastal roofs often see new growth sooner than the 3-5 years a soft wash typically lasts inland. A cleaning on a waterfront home is as much about keeping ahead of it as it is about the first result.
In Victoria Park and Sailboat Bend, many homes date to the 1920s and still have original surfaces. Those roofs get the gentlest approach we have, with chemistry calibrated to the material and its age. If we find broken tile or a failing pipe boot, we show you photos, since most damage cannot be seen from the ground.
We do not do roof repair ourselves. When a repair is needed, we can coordinate with roofers we work with so you do not have to find one on your own.
Docks, Waterways and HOA Paperwork
Many Fort Lauderdale homes back onto canals with private docks. Our chemistry is safe for waterway runoff, and we work carefully around boats and dock activity. For HOAs and condo associations, a Certificate of Insurance is available on request before any work begins.

Frequently Asked Questions
It is almost always Gloeocapsa magma, a hardy algae that thrives in South Florida humidity. It feeds on the porous surface of cement tile and the limestone filler in shingles. Rain and a hose only move it around, which is why the streaks keep coming back.
A soft wash kills the algae colony instead of rinsing the top layer off, so the roof returns to its original color and results typically last 3-5 years. Left alone, the growth spreads and shortens your roof's lifespan. You also get a close look at the roof, because any damage we find is documented and shown to you.
We never do. High pressure can crack cement and clay tile, dislodge ridge caps and force water under the flashing. Every roof we clean gets a low-pressure soft wash.
Most South Florida roofs stay clean for 3-5 years after a soft wash. Coastal and shaded roofs can see new growth sooner, so waterfront homes and lots under heavy tree cover tend to land at the shorter end of that range.
It depends on the size of the roof, the roof type and how much growth is on it. Send your address and a few photos and we can quote without a site visit. Online quote requests get a same-day response.
