Roof CleaningWinter Park, FL
Those black streaks on your roof are not dirt, and they are not permanent. They are Gloeocapsa magma, an airborne algae that spreads easily under Winter Park's heavy oak canopy. We remove it with a low-pressure soft wash that treats the algae itself, not just the visible staining, and we use the same approach on tile, shingle, and metal roofs. No high pressure touches the roof.
Why Soft Wash Your Roof Under the Oak Canopy
Treats the Algae Behind the Streaks
The black streaks are Gloeocapsa magma, an algae. We treat the algae itself, so it is slower to come back than after a surface rinse.
Treats Moss, Not Just Streaks
Black algae streaks are mostly a cosmetic problem. Moss is different: it holds moisture against the roof, and on shingles heavy moss can lift the edges. The same treatment works on moss as well as algae.
Consistent With Manufacturer Guidance
High pressure can strip granules. Some roofing manufacturers warn against power washing, and damage from improper high-pressure cleaning may not be covered under certain warranties. Our low-pressure soft wash avoids that damaging pressure.
Documented for HOA Review
A streaked roof draws a notice quickly under Winter Park's appearance standards. We leave it clean and document the finished work.

Why Winter Park Homeowners Trust Us With Their Roof
Winter Park has one of the densest tree canopies in the area, and shaded roofs stay damp long after the rain stops. Combined with humidity off the Chain of Lakes, those conditions allow roof algae to develop, and north-facing sections are usually affected first. Tile roofs also hold moisture and organic buildup within their textured surfaces.
A plain rinse only removes the surface growth and does not fully treat it, so it comes back a lot sooner than it should. We soft wash instead. Our low-pressure, soft wash treatment kills the algae itself, not just the surface stain. That makes it much harder for the streaks to come back, and it keeps the roof cleaner for much longer. Our roof-cleaning process also treats mold, moss, and lichen. The cleaning solution continues working for several days after application, breaking down the remaining organic growth so the roof gradually becomes cleaner and brighter even after the service is complete.
We clean roofs throughout Winter Park, including the Park Avenue historic district, Interlachen and the Vias, Windsong, Isle of Sicily, Hannibal Square, and out toward Aloma and Goldenrod. You get an experienced, owner-operated local crew rather than a franchise. We use a low-pressure soft wash on every roof, never damaging high pressure.
What a Pressure Washer Does to a Roof:
- Strips the protective granules off your shingles
- Cracks and dislodges tile
- Forces water up under the shingles, where it rots the deck
- High pressure can damage shingles and may affect manufacturer warranty coverage
- Only rinses the surface, so the growth survives and the streaks return
- Puts a worker on a wet, slick roof — one of the most dangerous places to stand
Algae usually shows up on more than the roof. While we are on site we can add gutter cleaning in Winter Park in the same trip, and the oak leaves and Spanish moss fill them quickly here. The walls below the roofline are handled with our house soft washing. Hard surfaces like the driveway are a different job, handled with pressure washing in Winter Park. See the full range on our soft washing hub, and every city we cover on our service areas page.
Property Assessment & Firm Quote
In most cases, we can price your roof remotely without scheduling an onsite estimate. We use aerial measurements to review the roof’s size and pitch, and ask about the roofing material and how heavy the streaking is, then provide a firm quote — usually within 1–3 business hours.
If we can’t accurately assess the property remotely, we’ll arrange an onsite visit. Once your quote is approved, your price won’t change unless the scope of work changes.
Schedule Your Service
Choose a service date that works for you. We confirm the appointment in advance and send you a text when our crew is on the way.
Same-week appointments may be available depending on the schedule.
Protect the Landscaping
Before applying the roof-cleaning solution, we thoroughly pre-wet the plants, shrubs, grass, and surrounding areas. We rinse the landscaping again afterward to reduce its exposure to overspray and runoff.
Apply the Soft-Wash Treatment
Using a professional soft-wash system, we apply the cleaning solution at low pressure across the roof. We adjust the application based on the roofing material and give additional attention to shaded and slow-drying areas where organic growth is often heavier.
The treatment targets algae, mold, moss, and lichen without using high-pressure washing.
Allow the Treatment to Keep Working
We apply additional treatments where needed, especially on heavily stained or shaded sections, until the entire roof has been thoroughly covered.
We typically leave the final application in place so it can continue breaking down any remaining organic growth. As the buildup loosens, normal rainfall gradually carries it away, and the roof may continue brightening over the following days.
Final Inspection and Photos
Once the final treatment has been applied and we have confirmed that every affected area has been thoroughly covered, we inspect the property and clean up the work area. We also provide before-and-after photos, which are useful especially for homeowners or property managers who are not at the property during the service.
Every roof cleaning is backed by our 1-year roof-wash warranty and satisfaction guarantee. If qualifying organic regrowth returns within 12 months, we will return and retreat the affected areas according to the warranty terms.
Soft Washing vs. Pressure Washing a Roof
This is the single biggest misconception in roof cleaning. We never pressure wash a roof. Here is what each method actually does once the water hits your shingles.
Soft Washing
Low pressure plus a professional cleaning solution that kills the growth, not just the surface. It is the only method we put on a roof.
- Kills algae, mold, moss & lichen, not just the surface
- Avoids the high pressure that can strip the protective granules off your shingles
- Suited to tile, metal, flat and low-slope roofs too
- Low-pressure method consistent with manufacturer guidance
- Results last far longer than a surface rinse
Why Not a Pressure Washer?
On a driveway it is the right tool. On a roof, here's what high pressure can do:
- Blasts the protective granules off shingles, cutting years off the roof
- Cracks and dislodges tile
- Forces water up under the roofing, where it rots the deck
- High pressure can damage shingles and may affect manufacturer warranty coverage
- Only rinses the surface, so the growth survives and regrows
- Puts a worker on a wet, slick roof, one of the most dangerous places to stand
What a Neglected Roof Actually Costs You
A roof soft wash costs a small fraction of what the roof is worth. Here is what waiting, or letting a pressure washer near it, tends to cost instead.
Roof Replacement
Algae streaks on their own are mainly an appearance problem. The real risk is moss, lichen, and trapped wet debris: they hold moisture against the roof and, left in place, can cause more serious maintenance problems.
Pressure-Wash Damage
One pass with a pressure washer can strip granules or crack tile across a whole slope, turning a cleaning into a repair and potentially affecting manufacturer warranty coverage.
Heat Absorption
Dark growth on a reflective roof can make the surface reflect less sunlight and absorb more heat. Clearing the growth helps that kind of roof reflect sunlight the way it was designed to.
Every Roof in the Area We Soft Wash
We use one low-pressure method on every common roofing material in Winter Park. We match the solution and its strength to whatever type of roof you have.
Tile Roofs
The signature roof through the historic district and the Mediterranean-revival homes off Park Avenue. Tile can crack under high pressure, so we soft wash it instead and keep heavy foot traffic off it wherever possible.
Shingle Roofs
Common on the newer streets out toward Aloma, Goldenrod, and Olympia, and the roof that stains fastest. We remove the black streaks at low pressure, because high pressure can strip the protective granules.
Metal Roofs
Standing-seam and panel roofs come back bright with a soft wash that is easy on the finish and the coating underneath.
Flat & Low-Slope
Flat sections drain slowly and stay damp under the canopy, which lets algae establish quickly. We treat them with the same low-pressure approach.
Moss & Lichen Removal
Moss and lichen build up heavily here, on shaded north slopes under the oaks and Spanish moss. We treat them as part of the soft wash. As the growth loosens, normal rainfall gradually carries it away, and the roof may keep improving over the following weeks.
Black Streak Removal
The dark streaks are Gloeocapsa magma algae. We treat the algae itself rather than rinsing the stain off the surface, so the results last much longer.

Why Roofs Streak So Fast Under the Oaks
Winter Park sits under the densest tree canopy in the area, and it is built around a chain of lakes. Both keep roofs damp. Warm, still air under the oaks is all Gloeocapsa magma needs. It is the airborne algae behind the black streaks on roofs across town, and it grows on the limestone filler inside shingles and settles into the texture of tile. That is why roofs here often stain faster than roofs in open, sunny subdivisions. A plain rinse does not remove it. Left untreated, it spreads across the slope. The streaks themselves mostly affect how the roof looks, but the same shade and damp let moss and lichen take hold too, and those hold moisture against the roof.
The Asphalt Roofing Manufacturers Association warns against using a power washer on an asphalt roof, because high-pressure washing is likely to damage it. We don't use high pressure on any roof. A professional roof-cleaning solution, applied at low pressure, treats the algae, mold, moss, and lichen. We typically do not rinse the roof afterward: the final application stays in place to keep working, and normal rain over the following days gradually carries the loosened growth away.
A soft wash also uses far less water than a pressure washer. Before we start, we pre-wet the landscaping around the house, and we rinse it again afterward.
Roof-cleaning needs vary across Winter Park. The historic district off Park Avenue and around Interlachen needs restraint, with tile under heavy oak canopy where the algae never dries out and boards that hold owners to strict appearance standards. Lakefront homes on Isle of Sicily and along the water carry mildew off the lake humidity. And the newer neighborhoods, Windsong and the shingle roofs out toward Aloma and Goldenrod, need consistency instead. We regularly serve all of Winter Park.
