Why SeaTac Homeowners Choose Pergolas

We build freestanding and attached pergolas in cedar, composite, aluminum, and louvered systems. In the Pacific Northwest, pergola design is primarily about rain management — lattice tops provide shade but no rain coverage; polycarbonate roofing provides full coverage; louvered systems give you both on demand.

A traditional open-lattice pergola provides shade from summer sun but does nothing for Seattle's 9 months of rain. Polycarbonate panel roofing or louvered aluminum systems are the PNW-appropriate specification — they provide the covered outdoor living space that actually extends seasonal use. We explain the tradeoffs clearly so homeowners choose the right system for how they'll actually use the space.
