Patio Covers in Snohomish & King County, WA

Get more months out of your patio or deck. NW Structures builds patio covers attached to your house or freestanding in the yard, with shingle roofing to match your home or clear panels that let the light through. With 25 years of building behind us, you get one licensed and insured builder from the first site visit to the finished cover.

How it works

  1. Tell us about the cover. Send the form below or call (425) 209-6553: the size of the patio or deck, attached or freestanding, and the roof you have in mind.
  2. Site visit. Dan looks at the patio, the roofline and the ground before quoting.
  3. Written quote and permits. A clear price for the cover you talked about. If it needs a permit, we take care of it.
  4. The build. We show up when we say we will and keep you posted on each step.

What our customers say

Questions we hear a lot

Attached or freestanding?

An attached cover extends the house and keeps the path to the door dry. A freestanding cover can go anywhere in the yard. We’ll talk through both at the site visit.

Which roof should I choose?

Shingles match most houses and are what most customers pick. Clear panels are the other option; they keep the rooms beside the patio bright.

Do I need a permit for a patio cover?

Many patio covers do. We’ll tell you what yours needs and take care of it.

Can you put a cover over my existing deck?

Yes. We build covers over new and existing decks. See our decks.

How much will it cost?

It depends on size, roofing and whether it’s attached or freestanding. We give you a written quote after seeing the site.
