Most homeowners ask us this question after they notice black streaks on the roof or a greenish film creeping across the driveway, not before. Fair enough. But if you want an actual number instead of a sales pitch, here’s the honest answer after 12 years of doing this across Broward County: it depends more on your specific property than most companies will tell you, and there are real intervals we see work.
Why Broward County Homes Get Dirty Faster Than Most of the Country
In a lot of the country, cold winters knock back algae and mold growth for a few months a year. That reset doesn’t happen here. Broward County stays warm and humid nearly year-round, and that keeps Gloeocapsa magma, the algae responsible for those black streaks on roofs, actively growing in every season. We often find that homeowners who moved here from up north are the most surprised by how fast a driveway or roof can go from clean to visibly stained.
Add in the near-daily summer thunderstorms and the salt air that reaches well inland from the coast, and you’ve got conditions that push most homes here toward cleaning intervals two to three times more frequent than the national average.
A Realistic Pressure Washing Schedule By Surface
There isn’t one answer for the whole house, since every surface weathers differently. Here’s what we actually recommend, based on what we see when we’re called out too late:
| Surface | Typical Interval | Signs It’s Overdue |
|---|---|---|
| Roof (soft wash) | 12-18 months | Black streaks, moss in shaded valleys |
| Driveway & walkways | 6-12 months | Green-black film, slippery when wet |
| Pavers & pool deck | 12 months | Color fading, weeds in the joints |
| Siding & stucco (soft wash) | 12-24 months | Mildew spotting, worst on north-facing walls |
| Wood & composite deck | 12 months | Graying wood, mildew in shaded corners |
What Actually Changes the Timeline
Two houses on the same street can need cleaning at very different rates. In our experience, the biggest factors are:
- Shade and tree canopy. Homes under mature oaks in neighborhoods like Victoria Park in Fort Lauderdale or the tree-lined streets of Plantation hold moisture longer after every rain, which gives algae a head start.
- Distance from the coast. Salt air accelerates staining on both roofs and driveways in waterfront communities like Harbor Beach, Coral Ridge, and Hillsboro Beach.
- HOA appearance standards. Plenty of Broward HOAs, particularly in Weston, Coral Springs, and Parkland, send violation notices well before a property looks bad to the untrained eye.
- Irrigation overspray. Sprinklers that hit the same stretch of driveway or the base of a wall every day keep that spot damp and speed up algae growth locally, even if the rest of the surface looks fine.
What Happens If You Wait Too Long
This is the part most homeowners don’t realize until it costs them. Algae doesn’t just sit on top of a shingle, it feeds on the limestone filler in the granule coating, which shortens the life of the roof if it’s left untreated for years. On concrete, stains that sit for a long stretch etch into the surface and stop responding to a standard clean, which means the job costs more and takes longer than it would have a year earlier. And if your HOA has already sent a notice, waiting longer just moves you closer to a fine.
Frequently Asked Questions
How often should I pressure wash my driveway in Florida?
Most Broward County driveways need attention every 6 to 12 months. Shaded driveways or ones near sprinkler heads often need it closer to the 6-month mark.
Is it bad to pressure wash too often?
Yes, if it’s done at high pressure. Repeated high-PSI cleaning can wear down concrete or strip protective coatings faster than the dirt would on its own. That’s a reason to hire someone who matches pressure to the surface rather than just blasting everything the same way.
Can I pressure wash my own roof?
You can, but a standard consumer pressure washer running at 2,000+ PSI is exactly what voids shingle warranties and cracks tile. Roofs need soft washing under 500 PSI, not more pressure.
Does pressure washing increase home value?
It doesn’t add value the way a renovation does, but it protects the value you already have and matters a lot for curb appeal if you’re listing the house.
What time of year is best to pressure wash in South Florida?
Late spring, before hurricane season ramps up, is when we see the most bookings. That said, algae doesn’t take a season off here, so there isn’t really a wrong time.
How do I know if my HOA requires cleaning?
Check your community’s governing documents or architectural guidelines, or ask your property manager directly. Most Broward HOAs address roof and driveway appearance somewhere in their rules even if they don’t advertise it.
