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.
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

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.

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.
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.

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!
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.

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.
