Every homeowner in Conroe, TX has thought about it at some point. The roof looks a little darker than it used to. The siding has some green streaking near the shaded side of the house. The driveway is getting grimy. But when exactly should you do something about it?
The honest answer is: it depends on the surface, your specific property, and the local climate. The Houston area is tough on homes. High humidity, frequent rain, heavy tree cover, and intense summer heat create ideal conditions for algae, mildew, and organic growth to build up fast. A surface that might need cleaning once every two years in a drier climate might need attention annually here.
This guide breaks it down service by service so you know exactly what to expect.
Roof Washing: Every 1-2 Years
Your roof takes the brunt of everything. In Conroe and The Woodlands, algae and black streaking from Gloeocapsa Magma (a type of cyanobacteria) is one of the most common issues homeowners deal with. That dark discoloration is not just cosmetic. The bacteria feeds on the limestone filler in your shingles and accelerates deterioration over time.
For most homes in the area, roof washing every 12 to 24 months is the right target. North-facing roofs, heavily shaded roofs, and homes surrounded by trees typically need attention closer to the 12-month mark. South-facing roofs with more sun exposure may go 18 to 24 months between cleanings.
Soft washing is the correct method for asphalt shingles. High-pressure washing can void your roof warranty and strip the granules that protect the shingles. Prestige Exterior Cleaning uses a low-pressure soft wash system with a specialized cleaning solution that kills the algae at the root, not just rinses it off the surface.
House Washing: Once a Year for Most Conroe Homes
The exterior walls of your home collect dust, pollen, spider webs, mildew, and oxidation from sun exposure. In this climate, an annual house washing keeps your home looking sharp and prevents buildup from embedding into the siding.
There are situations where you should do it more often. North-facing walls and heavily shaded areas accumulate green algae much faster than south or west-facing walls. If you notice visible green staining or dark streaking on your siding before the year is up, do not wait.
Homes near wooded areas or with large trees close to the structure also tend to need more frequent attention. The shade keeps moisture on the surface longer, which accelerates growth.
Gutter Cleaning: Twice a Year (Spring and Fall)
Gutters are one of the most maintenance-neglected parts of a home’s exterior, and also one of the most consequential when they fail. Clogged gutters back up during heavy rain, which is not uncommon in the Conroe area, and that backed-up water can work its way under the fascia, into the soffit, and eventually into the structure of the home itself.
The standard recommendation is spring and fall. Spring cleaning clears out the pollen, debris, and anything that blew in over winter. Fall cleaning handles the leaf drop before the wetter months arrive.
If you have large trees directly over your roofline, quarterly gutter cleaning is worth considering. Pine straw, seed pods, and small debris can clog gutters surprisingly fast in certain areas of The Woodlands.
Window Cleaning: Twice a Year, or Quarterly for Best Results
Hard water spots, pollen film, and general environmental buildup on windows are inevitable in this area. Most homeowners do well with two professional window cleanings per year, typically in spring and early fall.
If you are particular about your home’s appearance or you are planning to sell, quarterly cleanings will keep your windows looking sharp year-round. Windows are one of those things that you barely notice when they are clean and cannot stop noticing when they are not.
Pressure Washing for Concrete and Driveways: Once a Year
Concrete driveways, sidewalks, and patios develop oil stains, tire marks, mold, algae, and general grime over time. In the humid conditions common around Conroe and The Woodlands, biological growth on concrete is especially fast.
An annual concrete cleaning is the right baseline for most homes. If your driveway or patio sees heavy use, or if you notice significant growth or staining before the year is up, schedule it sooner. Concrete that stays damp in shaded areas may need cleaning more frequently.
One thing worth noting: cleaned and sealed concrete lasts significantly longer than concrete that is neglected. If you have not sealed your driveway recently, combining a cleaning with a sealant application is a smart investment.
Fence and Deck Cleaning: Once a Year Before Sealing or Treating
Wood and composite fences and decks take a beating from the Texas climate. UV exposure, moisture, mildew, and algae all accelerate the natural aging process of these surfaces. Cleaning them once a year, typically in spring before the summer heat arrives, keeps them looking good and prepares the surface for any sealing or staining that needs to happen.
For wood surfaces especially, cleaning before sealing is not optional. Sealing over a dirty or algae-covered surface traps the growth underneath and actually shortens the life of the material. A proper cleaning first is what makes the seal last.
Signs a Surface Needs Cleaning Sooner Than Scheduled
The schedules above are starting points, not strict rules. Here are signs that a surface needs attention before the calendar says so:
Visible algae or green streaking. This means active biological growth. The longer it sits, the more damage it does.
Noticeable discoloration. Dark staining on your roof, brown or black streaks on your siding, or heavy rust staining on concrete are all signs that buildup has progressed past the cosmetic stage.
HOA notice. If your homeowners association has flagged the appearance of your property, getting ahead of it with a professional cleaning is much easier than disputing it.
Preparing to sell. A clean exterior is one of the highest-ROI moves you can make before listing. It improves curb appeal immediately and signals to buyers that the home has been maintained.
Post-storm inspection. After any significant wind or hail event, an exterior inspection and cleaning can catch damage early and document the condition of your home before you file an insurance claim.
Consider a Bundled Exterior Maintenance Package
Rather than scheduling each service separately and trying to keep track of when each surface was last cleaned, many homeowners in Conroe and The Woodlands have found it easier to schedule a full exterior maintenance service once or twice a year that covers everything: roof, house wash, gutters, windows, concrete, and decking in one visit.
Prestige Exterior Cleaning offers bundled exterior maintenance services designed for exactly this. One appointment, one crew, everything done right. It is more cost-effective than scheduling each service individually, and it takes the scheduling burden entirely off your plate.
