Pergolas in Issaquah

Why Issaquah 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.
