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.

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.

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.

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.
