Covered Patios
Covered Deck and Patio Builder in Seattle | Mill Decking
Seattle doesn't pause for rain, and your backyard shouldn't either. A well-built covered deck extends your outdoor living season dramatically — protecting your surface, your furniture, and your plans from whatever the Pacific Northwest delivers. We build attached and freestanding covered structures with the same standard we bring to every deck we touch: permitted, detailed, and built to last.

FAQs
Do covered decks require permits in Seattle?
Yes — any structural roof addition requires a permit. We handle the full submission and municipality coordination as standard.
What roofing materials do you use?
We select materials based on your home's aesthetic and site exposure — options include metal roofing, composite panels, and cedar framing systems.
How long does a covered deck build take?
Typically 5–8 days depending on size and structural complexity.
Can you add lighting or a fan to the covered structure?
Yes — we rough in electrical during construction so any additions are clean and code-compliant from day one.
