If you’ve ever wondered whether your roof needs a cleaning — the answer is probably yes. At Cornerstone Cleaning, we often hear homeowners in Gig Harbor say, “It doesn’t look that bad.” But what’s growing up there isn’t always visible… until it’s a problem.
Why Timing Matters for Roof Washing
Roof maintenance isn’t about reacting to stains — it’s about preventing damage before it starts. That’s especially true in Gig Harbor, where ocean air, rainfall, and shade from trees create the perfect environment for roof decay.
Here’s how often we recommend roof washing in Gig Harbor:
-
Every 2 to 3 years for most asphalt roofs
-
Annually if you have heavy tree coverage or visible moss/algae
-
Immediately if you see dark streaks, green patches, or roof debris in your gutters
What Happens If You Wait Too Long?
Neglected roofs are more likely to:
-
Absorb water, leading to rot or mold growth
-
Trap debris that clogs gutters and downspouts
-
Lose shingle granules and deteriorate faster
-
Fail home inspections (especially if you’re planning to sell)
