Rain is the design brief
A cover that ponds, or that dumps onto the ledger, creates the rot we are usually called to fix. Drainage is drawn before the posts are set.

Covered Patios and Patio Covers
A cover is what turns a King County deck into a room you use in October. We build patio covers — welded steel with polycarbonate, or timber framed to the house — with gutters, posts and a flashing line that does not dump water into the siding. Most covers are paired with a new or rebuilt deck in the same project.
Included in this scope
- A cover designed with the deck, not bolted on after the fact
- Steel or timber frame, posts and footings sized for the roof load
- Polycarbonate, metal or a membrane roof, chosen for light and runoff
- Gutters and a discharge that misses the deck and the foundation
- Flashing where the cover meets the wall or the existing roof
Details that change the result
Light still matters
Clear or tinted polycarbonate keeps a north patio from becoming a cave. A solid roof is better when you want shade and a quieter rain.
One project, deck and cover
Building them together means the posts, railings and stairs land where the cover actually is. See the deck service if the surface itself needs to be replaced.

Questions
Before you call
Do patio covers need a permit?
Usually yes when the cover is attached to the house or the posts need new footings. Rules differ in Bellevue, Kirkland, Mercer Island and Sammamish. We flag what your city will ask to see.
Can you cover a deck we already have?
If the framing can take the extra load and the posts have a place to land. We check the ledger and the beams before we promise a cover on an existing deck.
Will it darken the rooms inside?
It can. We set the height, the roof pitch and a translucent panel where the cover crosses a window or slider, and we will say if a shorter cover is the better call.
