A patio cover is what you build when a pergola will not do the job. Slats give filtered shade, which is pleasant in a mild climate and insufficient when the afternoon sun is direct and the temperature is above 100. A solid cover blocks it completely, and that changes what the space is usable for from roughly half the day to all of it. It also introduces a problem a pergola never has, which is water. A solid roof collects everything that lands on it and puts it somewhere. In ground this dry, dumping concentrated runoff at the edge of a slab is a good way to undermine it or to send water toward the foundation over time, and because it only rains here a handful of times a year the consequence takes a long while to show. Drainage gets designed rather than left to run off the low edge. The wall connection matters just as much. A patio cover attaches to the house across a wide span and sits under whatever comes off the roof above it, which means the flashing detail at that junction is doing real work. Done poorly it channels water behind the siding. We handle that connection the same way we handle a deck ledger, on the basis that both are places where a structure meets a wall and water has to be told where to go.
We look at where the runoff will go before designing the cover, then at the wall connection, then at the posts and footings. Panel choice follows how much radiant heat you want to stop, since an insulated panel keeps the covered space cooler than a bare aluminum one that shades but still radiates. Where the cover goes over an existing deck or slab, we confirm that structure can take the posts. You get the drainage route, the wall detail, and the panel specification in writing before anything is ordered.

Blocks sun entirely and keeps the space usable through the hottest part of summer.
Cuts radiant heat transfer so the covered space stays cooler than the shade alone.
Routes runoff away from the foundation and seals where the cover meets the house.

Ten services, from a full pool deck build down to a railing swap or a season of stain. Every one of them starts the same way: we look at what the structure sits on, how high it stands above grade, and what the sun does to that side of the house through a Tri-Cities summer.

We work Pasco first and five surrounding communities after it. Two of them are unincorporated, which means county permits rather than a city building department, and one runs a municipal electric utility instead of a PUD. Those differences change the sequence, so we sort them out before scheduling.
Frequently Asked Questions
Deck Contractor can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
There is no single price for a Pasco deck. Cost follows the square footage, the height above grade, whether the framing underneath can be reused, the decking material, and whether the railing is wood, cable, or aluminum. A ground-level platform in an existing footprint and an elevated deck with new footings are not comparable jobs. We price after a walkthrough and measurements, not over the phone.
It depends on two numbers. Pasco Municipal Code exempts decks under 200 sq ft that also sit under 30 inches above the ground, so a small ground-level platform can go in without a permit. Cross either threshold and you need one from the City of Pasco Building Division, where residential permits run a five to seven business day review. We confirm which side of that line your project falls on before quoting it.
For a Pasco summer, the honest answer is that surface color matters more than material category. Lighter boards run cooler underfoot than dark ones, in composite and in wood alike. Composite avoids the annual splintering and checking that dry heat causes in softwood, while a good hardwood or cedar stays cooler than most dark composites. We match the material to how the deck is oriented and how often it is used barefoot.
Ask three things. Whether they build decks specifically or take them alongside fencing and general contracting, whether they will tell you the permit threshold before quoting, and whether their past work is in your climate rather than on the wet side of the state. A crew that cannot answer the permit question in the first conversation has not looked at your project yet.
Schedule follows the permit review, the footing and framing inspections, whether concrete has to cure before framing starts, and lead times on decking and railing. A railing replacement on sound framing and a new elevated deck that needs fresh footings sit at opposite ends of that range. We give you the sequence in writing so you can see which steps are ours and which belong to the city.
Wood is cheaper up front and needs a finish schedule. Composite costs more at install and skips the stripping and staining. In this climate the gap widens, because dry heat and hard sun push a softwood deck toward recoating more often than the same deck would need on the coast. The right choice depends on whether you would rather spend the money once or spread it across seasons of maintenance.
A pergola has open slats and gives filtered shade that varies through the day. A patio cover has a solid roof and blocks sun completely while also shedding rain. In Pasco summers a solid cover keeps a space usable through the afternoon in a way that slats generally will not.
Wherever it is designed to, which is the point. A solid roof concentrates runoff, and letting it dump at the slab edge can undermine the slab or push water toward the foundation over time. We plan the drainage route before building rather than after.
If the covered space is used through the hottest part of the day, usually yes. A bare panel shades the space but still radiates heat downward once it warms up. An insulated panel cuts that transfer, which is a noticeable difference on a west-facing patio in July.
Usually, provided the slab can take the post loads or footings can be placed alongside it. We check the slab thickness and edge condition at the walkthrough. Where the slab will not carry it, independent footings beside the patio are a straightforward alternative.
