The Importance of Deck Maintenance in the Pacific Northwest
The Pacific Northwest’s wet climate creates the perfect conditions for moss, mold, and mildew to grow on outdoor surfaces—especially decks. Without regular cleaning and maintenance, these elements can cause rot, staining, warping, and even safety hazards.
That’s why proactive deck care is essential. At Fast Roofing, we tailor each maintenance plan to your deck’s material and condition. Whether you live in Seattle, Portland, or anywhere in between, we protect your deck from weather-related damage and help extend its life, saving you money on repairs or replacements down the road.
