Pressure Washing After a Hurricane in Florida: What to Clean First

If your Lakeland or Polk County property has just come through a tropical storm or hurricane, the exterior of your house took a beating you can’t fully see yet. Wind-driven rain forced organic debris into corners, swept algae spores across surfaces that were previously clean, and probably left a layer of leaf-mash on every horizontal surface. Pressure washing is part of the recovery, but the order matters and the timing matters.

This guide is what we tell our Lakeland customers when they call after a storm. It’s not a sales pitch — there are real things you should do yourself before any pressure-washing company gets near the property.

Wait 48 to 72 hours before any washing

Two reasons.

First, insurance documentation. If there is wind, water, or impact damage to the property, you need photos of the property as the storm left it. Your adjuster needs to see the debris, the staining, the runoff patterns. Pressure washing it away before documenting can complicate or weaken a claim.

Second, the surfaces are saturated. Pressure washing wet, swollen wood can splinter or gouge it. Pressure washing saturated stucco can force water deeper into the wall assembly. Soft-wash chemistry works better when surfaces have had a day or two to dry. Give it the time.

The exception is when standing water or organic mass is actively damaging something — for instance, a thick layer of leaf-and-pine-straw on a tile roof that’s holding water against shingles. In that case, gentle removal (by hand, not by pressure) is the priority. Leave the actual washing for later in the week.

What needs cleaning first, in order

After a major storm, here’s the order we recommend:

1. The roof

Storm debris on a roof is the most time-sensitive. Wet leaves, pine straw, and limbs trap moisture against shingles and can accelerate algae growth dramatically — especially in Florida’s heat. Within 7 to 10 days of a hurricane, the black streaks of Gloeocapsa magma can establish on shingles that previously looked clean.

The right approach is a low-pressure soft-wash treatment, which kills the algae before it spreads. Never high-pressure wash a roof — every major shingle manufacturer voids the warranty for that, and it actively shortens roof life. ARMA (the Asphalt Roofing Manufacturers Association) endorses the low-pressure soft-wash method only.

If there are limbs or large debris on the roof, those come off first by hand (with proper safety equipment) before any chemical washing.

2. Gutters and downspouts

A post-storm gutter is usually packed with debris — leaves, pine straw, small twigs, sometimes shingle granules if the roof took impact. Clogged gutters during the next rain (which in Florida is usually within days) overflow against the soffit and fascia, causing water damage that’s both expensive and easy to prevent.

Interior gutter cleaning should happen within the first week post-storm. While we’re up there, we usually also do gutter brightening to remove the black tiger-striping that often appears after a storm — wind-driven debris bonds chemically to the gutter face and ordinary washing won’t remove it.

3. House siding and exterior walls

Once the roof and gutters are clear, the siding gets a soft-wash house cleaning. Hurricane-driven rain pushes algae spores and mildew into siding pores at high velocity — the result is often a wash of green or grey staining that looks like the house aged 5 years in a single storm. Soft-washing kills the organic growth at the root and rinses it clean.

This is not the time for high-pressure washing on siding. Wet, possibly stressed siding (especially vinyl, stucco, or Hardie that may have been impacted by debris) is more vulnerable to damage than ever. The right approach is low-pressure cleaning with a biodegradable detergent that does the actual work.

4. Driveways, walkways, and pool decks

Storm water often deposits a film of mud, organic mash, and embedded debris on driveways and walkways. This is a perfect surface-cleaner job — a rotating commercial pressure ring distributes pressure across a 16 to 20 inch path and lifts the contamination evenly. We almost always handle driveway cleaning as part of a post-storm property refresh.

Pool decks and screened lanais take particular damage in storms — screens may be loaded with leaves and pine straw, paver decks may have shifted joint sand, and cool deck may show new staining from runoff. Pool deck cleaning post-storm is a careful, low-pressure job.

5. Fences and outbuildings

Wood fences in particular grey out fast after storm exposure, and the grain often raises from the saturation. Fence cleaning and brightening restores the color and prepares the surface if you need to seal or stain.

What insurance will and won’t cover

This is where homeowners trip up. In our experience working with Polk County properties post-storm:

• Covered: Direct damage from wind, debris impact, or water intrusion. If a limb broke off and impacted siding, that’s damage. If water got behind the siding from wind-driven rain at the seams, that’s damage. Document with photos before cleanup.
• Not covered: General staining, algae growth, mildew, and the cosmetic effects of a storm. These are considered maintenance items. Insurance won’t pay for the wash, but the wash protects the surfaces from longer-term degradation.

If you’re filing a claim and want exterior cleaning included, get the cleaning quote in writing before the wash — adjusters appreciate the documentation, and in some cases (particularly where staining is paired with damage), partial cleaning coverage gets approved.

Two mistakes that make things worse

Mistake 1: Pressure washing the roof immediately after a storm. A saturated shingle roof at high pressure loses granules. The granules are what protect the shingle from UV. Stripping them shortens the roof’s life by years, possibly decades, in a single afternoon. Soft-wash only, and only after 48 to 72 hours of drying.

Mistake 2: Pressure washing wet wood at full PSI. Saturated wood splinters and the grain raises. The result is a fuzzy, grey-toned wood surface that’s worse than what you started with. Wood gets a low-pressure approach with a cleaning agent doing the work. Wood brightener afterward if you want to restore the warm tone.

When to schedule the work

The first 30 days post-storm is when the most damage compounds. Algae establishes on wet surfaces, mildew spreads in the humidity, debris-clogged gutters overflow against the house, and pool chemistry destabilizes. Most of our Lakeland customers who get washed within 2 to 3 weeks of a hurricane recover the property’s appearance fully and prevent the second-wave problems.

We work post-storm clusters routinely — usually a house wash, roof cleaning, and driveway combo at combo pricing. The whole property comes back to where it was, sometimes better.

If you’re in Lakeland, Winter Haven, Bartow, Auburndale, or anywhere in Polk County and just came through a storm, text photos to (863) 887-6769. We’ll quote it the same day, schedule it for the first dry window, and treat the property like it’s our own.
