Enjoy the Outdoors — Rain or Shine

Covered Decks & Patio Roofs in Washington

Weatherproof Your Favorite Outdoor Space

Custom Roof Structures for Shade and Shelter

Washington’s wet seasons shouldn’t stop you from enjoying your deck. We build custom patio roofs, full overhead covers, and integrated shade structures that match your home’s style and protect your space. From open-beam cedar to fully shingled gables, our covers are built to code and made to last.

Stay Dry. Stay Cool. Stay Outside Longer.

Deck Covers That Blend Form and Function

A roofed deck or patio keeps the rain off and the sun in check — letting you relax outside more months of the year. We design each cover to suit your home, your deck layout, and your budget. Choose from attached roofs, freestanding pergolas, vaulted structures, or low-profile covers.

  • Gable, hip, shed, and flat roof options

  • Tied into existing home rooflines or freestanding

  • Built with engineered lumber, posts, and flashing

Built for Looks and Lasting Protection

Strong Framing and Clean Finishes Every Time

Our patio covers aren’t prefab kits. We frame from scratch using pressure-treated lumber or Douglas fir, sealed and finished to suit your taste. We match trim, pitch, soffits, and even shingles for a seamless appearance. It doesn’t just look like it belongs — it is part of your home.

Cover the Deck You Already Have

Add a Roof Without Starting from Scratch

Already have a deck? We can evaluate it and add a roof structure that connects safely and looks natural. We check your framing, reinforce as needed, then build a cover that ties into your siding or stands free nearby. You’ll get more use out of your existing space — and protection for years to come.

Built for Washington Weather — and Washington Code

Roof Structures That Withstand Rain, Wind, and Time

Covered decks in Washington face heavy rainfall, wind gusts, and occasional snow loads. We build roof structures that meet or exceed local code, using galvanized connectors, sealed seams, and correct pitch for drainage. Whether you choose metal panels, shingles, or open-beam designs, your cover will be strong, dry, and built to last.

Why Homeowners Trust Our Covered Deck Builds

  • Custom Framing & Trim: Every cover is framed to match your home — no cookie-cutter kits.

  • Code-Compliant Roof Loads: We engineer each roof to handle local snow, wind, and storm requirements.

  • Seamless Style Match: We match roof pitch, soffits, siding, and finishes for clean integration.

  • Covered From Below: Optional ceiling panels, fans, and lighting packages available.

  • Long-Term Durability: Materials rated for moisture, rot, and insect resistance in wet climates.

Don't worry, we can help!

Add Features That Make the Space Your Own

Want more than just cover? We offer lighting, fan mounts, heaters, skylights, tongue-and-groove ceilings, and even enclosed walls. Whether it’s a place to grill in the rain or a cozy sitting zone year-round, we’ll build the outdoor room that fits your lifestyle.

  • Outdoor lighting and ceiling fan options

  • Skylights and privacy wall upgrades

  • Screened enclosure add-ons available

We Handle It All — Start to Finish

Design, Permits, Build, and Final Inspection

Covered decks require permits and structural planning — and we take care of all of it. You don’t need to file paperwork or chase approvals. Our team handles designs, engineering (if needed), permitting, and the final inspection checklist. You get a protected space without the project headache.

Thinking About Adding a Roof to Your Deck?

Here Are the Questions We Hear Most

Covered decks offer comfort and style — but also come with smart considerations. Here’s what our clients want to know.

Question 1: Do I need a permit to add a roof to my deck?

Yes. We pull the permit, submit designs, and ensure full compliance with local codes.

Question 2: Can I add a cover to an existing deck?

Often, yes. We inspect the deck to confirm the structure can support a roof, and reinforce as needed.

Question 3: What roof styles are available?

Gable, shed, hip, and flat designs — matched to your home’s style and elevation.

Question 4: Can I enclose part of the covered area later?

Absolutely. We design with future screened walls, glass panels, or sunrooms in mind.
