Signs You Need Exterior Cleaning
If your home is starting to look weathered, dirty, or overgrown, it might be time for a professional exterior cleaning. In the Portland area, our damp climate causes moss, algae, and grime to build up quickly on roofs, siding, driveways, and more. Ignoring these warning signs can lead to damage and expensive repairs. Below are some of the most common indicators that your property is overdue for an exterior cleaning service.
1. Moss or Algae Growth on Your Roof
If you notice green moss or black streaks on your shingles, it’s more than just an eyesore—it can lead to roof damage and leaks. Portland’s wet climate makes roofs especially vulnerable, so regular roof cleaning is essential.
2. Green or Black Stains on Siding
Algae, mold, and mildew thrive on siding in shady or damp areas. These stains not only lower curb appeal but can also eat away at paint and materials over time.
3. Dirty or Slippery Driveways and Walkways
Built-up grime, moss, and oil stains can make concrete surfaces slippery and unsafe. Pressure washing helps restore traction and removes years of buildup.
4. Clogged or Overflowing Gutters
Leaves, moss, and debris in your gutters can cause water to back up and damage your roof or siding. Exterior cleaning often includes or pairs well with professional gutter cleaning.
5. Foggy or Streaked Windows
When windows are constantly foggy or streaked despite cleaning them yourself, it’s usually due to buildup on the exterior glass. A professional window cleaning can bring back clarity and light.

FAQ's
1. How Much Does Pressure Washing Cost?
Pressure washing costs typically range from $200 to $600, depending on the size of the area, surface material, and level of buildup. For example, cleaning a standard driveway or patio may be on the lower end, while full-house washing and larger driveways may fall toward the higher range. At Anderson Exterior Maintenance, we offer free, no-obligation estimates and competitive pricing across the Portland metro area. Contact us today to get a custom quote for your home or business.
2. Is Pressure Washing Safe On My Driveway?
Yes — when handled by professionals, pressure washing is completely safe for both siding and driveways. At Anderson Exterior Maintenance, we adjust the pressure and use the right techniques for each surface to prevent any damage. For siding, we often use a gentler method to remove mold, algae, and dirt without harming paint or materials. On concrete and hard surfaces, we use powerful but controlled pressure to restore surfaces safely and effectively.
3. How Often Should I get a Pressure Wash?
In Oregon’s wet, moss-prone climate, most homeowners benefit from annual pressure washing for siding and driveways. Regular cleanings help prevent buildup of algae, mold, and grime, keeping your home’s exterior looking sharp and well-maintained. Siding typically needs cleaning once a year, while high-traffic driveways may benefit from a wash every 12 months. Ask us about our routine maintenance plans to protect your home and boost curb appeal year-round.
4. How Much Does Roof Cleaning Cost?
Roof cleaning typically costs between $300 and $800, depending on the roof size, pitch, and moss or algae buildup. At Anderson Exterior Maintenance, we provide custom quotes based on your specific needs and offer affordable, professional soft washing to protect your roof’s lifespan. We serve homeowners throughout the Portland area with transparent pricing and no hidden fees — contact us today for a free estimate.
5. Is Roof Cleaning Necessary In Oregon?
Yes — Oregon’s damp, shaded climate makes roof cleaning essential for preventing moss, algae, and lichen growth. Left untreated, moss can cause shingles to lift and degrade, leading to expensive repairs or premature replacement. Regular soft washing not only protects your roof but also improves curb appeal and helps maintain your home’s value. We recommend scheduling a professional roof cleaning every 2 to 3 years, or sooner if you see visible moss.
6. What Is The Safest Way To Clean A Roof?
The safest and most effective method for cleaning a roof is soft washing — a low-pressure system that uses biodegradable cleaning solutions to kill moss, algae, and mold at the root. Unlike high-pressure washing, soft washing won’t damage shingles or strip away protective granules. At Anderson Exterior Maintenance, we specialize in soft washing services that safely restore your roof and extend its life, with results that last.
