Introduction

Roof stains in Jacksonville almost always trace back to the same cause: algae, encouraged by the area's humidity, rainfall, shade, and roofs that don't dry out quickly after a storm. Bold City Drone Wash cleans roofs across Jacksonville, we're veteran-owned, family-owned and operated, licensed and insured.

We match soft washing and drone-assisted methods to your roof's material and condition, rather than defaulting to one approach for every job. Call 904-921-2133, text 904-789-7733, or schedule a free estimate and we'll take a look at your roof in person.

Those dark streaks running down a shingle roof are commonly caused by algae. They're often mistaken for dirt or mildew. Jacksonville's humid conditions can encourage algae growth, especially on roofs that remain shaded or damp after rain.

Storm season debris, leaves, pollen, and organic material sitting in valleys and gutters can create conditions that support algae growth. Left unaddressed, staining and organic buildup can worsen the roof's appearance and create ongoing maintenance concerns.



Dark streaks on the less-sunny side of your roof may indicate early algae growth. A dull-looking section can be another sign the roof needs a closer look.

We start by looking at your roof's material, pitch, and the extent of the staining before choosing a method.

What Is Soft Washing?

Soft washing uses a cleaning solution at low pressure to treat the organic growth rather than relying on force to blast it from the surface. It's the method we use most often on shingle roofs.

When Do We Use Drone-Assisted Cleaning?

For roofs that are steep, high, or difficult to reach safely with ladders or foot traffic, we use drone-applied soft washing to apply the same approach from the air. This method reduces the need for anyone to walk directly on the shingles during the cleaning process.

Yes. Soft washing is generally safer for asphalt shingles because it doesn't rely on high pressure to force algae and buildup off the surface. Standard high-pressure washing can strip granules off asphalt shingles, force water under flashing, or loosen shingle edges, damage that isn't always visible right away.



For asphalt shingles, we do not use high pressure. Controlled pressure may be appropriate for certain non-shingle surfaces, such as concrete or some metal areas, but it's never our default method on a roof. If you're comparing the two methods for your specific roof, our soft wash vs pressure wash comparison breaks this down further.

Climbing onto a roof to clean it yourself carries real fall risk. DIY cleaning also often means using the wrong pressure or the wrong chemical mix, which can damage shingles or affect landscaping below without you realizing it until later.



Hiring a professional means the method gets matched to your specific roof. Our drone-assisted cleaning is performed by FAA-certified remote pilots, and this approach reduces how much foot traffic your roof needs during the job, though some access equipment may still be used depending on the property. Our roof safety guide goes deeper into what makes professional cleaning safer for the roof itself.

Most residential roof cleaning jobs take a few hours to complete, though the exact time depends on several factors. Roof size and pitch affect how long the job takes, a larger or steeper roof takes more time to cover carefully. The amount of existing buildup matters too, a roof that's been neglected for years takes longer to fully treat than one caught early.

Weather and access also play a role. We schedule around dry conditions when possible, and roofs with limited access or nearby obstructions may require extra planning time before the cleaning itself begins.

Cost depends on a handful of factors rather than a flat number. Roof size and pitch are the biggest drivers, and the severity of the staining matters too, since a heavily built-up roof takes longer to treat than one caught early.



Material also plays a role, since shingle, tile, and metal roofs each respond differently to soft washing. The clearest way to get an accurate number for your roof is a free estimate, where we look at the actual condition and give you a real figure.

The most immediate benefit is how much better your home looks. Regular cleaning can help reduce how much algae builds up over time, though how quickly it returns depends on shade, moisture, nearby trees, roof material, and other conditions specific to your property.



For coastal properties, the cleaning process can also address surface residue and organic buildup that tends to accumulate faster near the water. If you're weighing drone-assisted cleaning against a traditional crew, our drone vs traditional comparison covers that in more detail, and our drone pressure washing overview explains the full process behind how we clean.

Homeowners with visible dark streaking, green patches, or a roof that hasn't been cleaned in a few years are the most common customers we see. HOA communities and property managers also bring us in to keep shared rooflines consistent across a neighborhood. Our multi-unit and HOA drone pressure washing service covers that side of the work in more depth.

Commercial property owners with flat or low-slope roofs also use us to clear debris and organic buildup before it causes drainage issues. Our commercial drone pressure washing service goes into that further.
