We build pergolas on existing decks and concrete patios across South Hill, Five Mile Prairie, and Spokane Valley. Attached pergolas require a permit in Spokane when they connect to the house structure, and we handle those drawings.
An attached pergola connects to the house's ledger or fascia and draws its support from both the house and its own posts. This is the most common setup for Spokane homeowners who want shade over a patio door or deck area. A freestanding pergola stands on four or more posts with no house connection, which gives more placement flexibility and avoids any concern about the existing house wall framing. Both types require footings set below Spokane's frost depth to prevent post heave over winter.
Spokane can see 20 to 40 inches of snow in a heavy winter, and a pergola roof needs to account for that load. Open-lattice pergolas shed snow better than solid roofing, but for real weather protection you need a solid pan roof or a polycarbonate panel system. We size the beams and rafters to the span and the expected snow load for your specific site, not a one-size plan. Cedar and pressure-treated posts are both good choices for Spokane's climate.
Spokane County generally requires a building permit for any attached pergola and for freestanding structures over a certain square footage. We pull the permit, submit the drawings, and schedule the inspection. You do not need to coordinate with the city directly. The permit process adds one to two weeks before we can break ground but protects your homeowner coverage and makes the structure easier to include at resale.
$5,000 to $14,000 for a standard pergola, depending on size and post configuration
Most pergola installations take two to four days on site once the permit is in hand. Footing pours need a day to cure before we set posts, so we usually schedule that as a separate day from the framing work.
A well-built pergola with properly sized beams can handle typical Spokane snowfall. Open-lattice roofs shed snow more easily than solid roofing. For heavy snow protection with a solid roof, we use heavier beam sizing and closer rafter spacing to meet the load requirements.
Yes. Pergolas are commonly added to existing decks. We inspect the existing deck framing to confirm it can carry the pergola post loads. If the deck was built to code with proper footings, it usually can. If the footing depth is too shallow, we can add piers adjacent to the existing structure.
A pergola has an open or partially open roof with rafters or lattice, which provides shade but not full rain protection. A patio cover has a solid or corrugated roof that keeps rain off. In Spokane, many homeowners start with a pergola and add solid roofing panels later when they want full weather protection.
We built this operation around one idea: a deck is a structural investment, not a cosmetic one, and it deserves the same care you would put into any other part of your home. We work across Spokane, South Hill, Five Mile Prairie, Mead, and the Spokane Valley. Every build gets a permit, pressure-treated or composite framing rated for the Pacific Northwest, and a final inspection before we call the job done. We give you a flat written estimate after the site visit and we stand behind the work with a workmanship warranty.
