Venice, FL
What does roof cleaning in Venice involve?
Venice has two roof populations and the Intracoastal runs between them. On the island side the housing stock is old, and the roofs match it. Barrel tile, flat tile, low slope and metal, plenty of it up for decades. Tile is the surface that shows growth worst, because every barrel holds shade and water in the low part of the course, and a low slope roof drains slowly enough that the growth spreads as a field instead of a streak. Salt haze comes straight off the Gulf on that side and settles on top of everything, so an island roof dulls between the streaks as well as along them.
Cross the bridges and it changes. Venice Gardens, South Venice and Pinebrook South grew up under real oak canopy, so the roofs there are mostly shingle and the streaking starts on whatever run of it sits in shade the longest. Out east off Jacaranda Boulevard, in Pelican Pointe, Chestnut Creek and the Venice Golf and Country Club, the streets are uniform and one streaked roof stands out against forty that aren't. All of it gets the same treatment. A maximum of 70 PSI from a battery operated pump, which is garden hose pressure, with the mix matched to tile, shingle or metal. Old tile is exactly why that number matters.

Tile hides its own problem. Look at a barrel tile roof from the street and you see the tops of the courses, which are the parts that dry fastest and stay cleanest. The growth is down in the low half of every barrel where the shade sits, and that's why a roof can look patchy and unconvincing from the driveway and read solidly green from the neighbor's second floor. Flat tile and low slope roofs do the opposite. They darken evenly across the whole field, so people call them weathered rather than dirty and leave them for years.
On the mainland the tell is direction. A shingle roof under oaks streaks on the north facing runs and the shaded runs first, and the streak widens downhill because rain is how the growth travels. On the deed restricted streets out east it usually gets noticed by somebody else first. An association letter about a roof is one of the most common reasons a Venice homeowner calls, and what your association asks for and how long it gives you is between you and them.
Salt sits on top of all of it near the water. Around the Venetian Waterway, the streets off Roberts Bay and out toward Caspersen Beach, the film is salt plus growth on the same surface, which is why those roofs go flat and dull rather than obviously black. One soft wash carries both off together. Nothing about the method changes from one side of the bridge to the other. What changes is what's sitting up there when we arrive.

What the Black Streaks Actually Are
The streaking on Florida roofs is a living growth, mostly algae, with mold and mildew alongside it in the shaded spots. It feeds on the roof surface and holds moisture against it. Heat and humidity keep it fed, which is why it starts on the north side and the shaded runs first, then spreads.
It doesn't wash off in the rain. Rain is how it travels. Left alone it keeps moving course by course until the whole roof reads black from the street. Killing the growth is the job. Knock the streaks off without killing what causes them and they're back by next season.
Cleaned at 70 PSI. That's Garden Hose Pressure
A pressure washer runs 3000 to 4000 PSI. That kind of pressure belongs on concrete, and concrete is the only place we point it. Your roof gets a maximum of 70 PSI from a battery operated pump. About what comes out of a garden hose. There's no loud machine sitting on your roof and no wand blasting at your tile.
The actual cleaning is chemistry. We apply a surfactant based soap and degreaser mix matched to the surface, then let it kill the growth and release its grip. A rinse at that same low pressure carries it off, streaks and all.

Shingle, Tile and Metal
Tile carries the heaviest visible growth, because the barrel profile holds shade and moisture on every course. Shingle shows it as long black streaks running toward the gutter. Metal shows it along panel lines and wherever water sits. Different look, same organism, same fix.
What changes is the mix, not the pressure. The blend is matched to the surface, so tile isn't treated like shingle and painted metal isn't treated like either. The 70 PSI maximum never moves. Low slope and flat roofs get the same treatment, and the flat roof in the photos below shows what that looks like.
Why We Never Blast a Roof
High pressure on a roof causes the exact damage you're afraid of. It lifts tiles and cracks them, strips the granules off shingle, and drives water up under the courses where it has no business being. A roof cleaned that way looks fine from the truck and fails early.
That's why the 70 PSI figure matters. It isn't a slogan, it's the pressure the pump physically runs at. Anyone can say soft wash. A number is harder to fudge.
Dilution Is the Solution
The fear that actually stops people booking a roof cleaning isn't the roof. It's the landscaping under it. Runoff from a roof wash ends up in the beds, and a strong mix left sitting there will burn whatever it lands on.
So the rinse gets the same care as the wash. When the roof is done, the chemical gets diluted down so far it stops acting on anything. Dilution is the solution. One thing on your side of the job: if you have irrigation around the house, run it before we arrive and for at least a week to 10 days after we leave, so nothing dies at the root. Your hedge shouldn't pay for your roof.
When to Clean, and How Long It Lasts
Most calls come in when the streaks show from the street, when the HOA sends a letter, or when a house is going on the market and the roof is dragging the listing photos down. Before painting is another good time. A clean roof changes how the whole house reads.
Results typically stay clean about a year. Heavy shade and overhanging oak bring the growth back faster, full sun holds it off longer. When it starts creeping back, call. We'll tell you straight whether it's time or whether it can wait a season.

If it's black or green, we will make it clean. And your tile, your shingle and your landscaping will all still be intact when we leave.
Will pressure washing damage my shingles or lift my tiles?
We don't pressure wash roofs at all. Your roof gets a maximum of 70 PSI from a battery operated pump, which is garden hose pressure. Nothing lifts a tile, nothing strips shingle granules, and there's no machine roaring away up there. High pressure stays on the driveway, where it belongs.
Will the chemicals kill my plants?
No. The mix is matched to the surface, and when the roof is done we dilute the chemical down until it stops acting on anything. Dilution is the solution. If you have irrigation, run it before we arrive and for at least a week to 10 days after we leave, so nothing dies at the root.
What kinds of roofs do you clean?
Shingle, tile and metal, plus low slope and flat roofs. Same maximum of 70 PSI on all of them. The surfactant mix changes with the surface. The pressure doesn't.
How long does a roof cleaning last?
About a year is typical. Shade, overhanging trees and the north side bring growth back sooner, full sun holds longer. Some roofs need a maintenance clean to keep the mold from getting re-established. When you see it coming back, call and we'll tell you straight.
The HOA sent me a letter about my roof. Can you handle it?
It's one of the most common reasons people call. Send a photo of the roof, get a free quote back by text or phone, and one clean at 70 PSI takes off the streaks the letter is about. Deadlines on those letters vary, so don't sit on it.
How much does roof cleaning cost?
Every job is quoted free, online, by text or over the phone. Roof size, pitch and how far the growth has spread all move the number, so send a photo or two of the roof and Matt gives you a real price back. Nobody waits around for an appointment window, and there's no obligation either way.
Our tile has been up since the eighties. Is it too old to clean?
Age isn't the problem. Pressure is, and old tile is the best argument there is for a maximum of 70 PSI. High pressure on brittle tile lifts it, cracks it and pushes water up under the courses, which is the damage everyone is actually afraid of. Garden hose pressure with the right mix doesn't. If a tile is already cracked or slipped, a cleaning won't fix that, and Matt will tell you what he can see rather than talk around it.
We have a low slope roof, not a pitched one. Do you clean those?
Yes, and there are a lot of them in Venice. Low slope and flat roofs hold water longer and dry slower, so instead of streaks they go dark across the whole surface, evenly enough that people assume it's just age. Same maximum of 70 PSI, same surface matched mix. The difference is usually how surprised owners are by the after.
The streaks came off but the tile still looks dull. What is that?
Two things, and it's worth separating them. Film comes off. Decades of weathering on the tile itself does not, because that's the surface of the tile and not something living on it. A wash takes the roof back to its own colour, not to a colour it hasn't been since it was laid. Anyone promising otherwise on forty year old tile is selling you something.
The listing photos are booked for next week. Is that enough time?
Usually, and the quote is not the slow part. Text over a couple of photos of the roof and a real number comes back, no appointment to wait on. We work Monday through Saturday, 8am to 7pm. A clean roof changes how the whole house reads in a listing photo, so it's worth getting done before the photographer rather than after.
