We build covered decks and patio roofs that give you shade in the summer, protection from rain, and shelter from snow—all without closing off your view. Our projects are framed to match your home’s roofline or support structure, using wood or composite materials rated for Montana conditions. Whether you want a gable roof, shed-style, or pergola, we design each cover to enhance comfort and increase your home’s usable square footage.
A covered deck transforms your space from seasonal to year-round. Montana’s UV rays, rainstorms, and snowfall can quickly age unprotected decks. Adding a roof not only improves comfort it also protects your investment. Covered spaces stay cleaner, safer, and easier to maintain. Plus, they create outdoor zones that feel like true extensions of your home.
Extend your outdoor season by months
Reduce fading and damage from sun and snow
Add privacy, comfort, and resale appeal

We design every roof and overhead structure to meet local snow load, wind rating, and code requirements. Whether free-standing or attached, our covered decks are built with pressure-treated posts, galvanized hardware, and structural supports that won’t sag or shift. From Kalispell to Billings, we know how to build for weather so your roof doesn’t just look good, it performs all year.

Every covered deck starts with the right design. We offer gable roofs for symmetry and headroom, shed styles for clean, modern lines, and pergolas for partial shade. Want something unique? We build custom roof structures to tie in with your home’s elevation, siding, and window placement. Add skylights, ceiling fans, heaters, or lighting for even more function. Our goal: a structure that fits and feels like it’s always been there.
Covered structures require careful planning and local approvals. That’s why we manage everything from structural drawings and code compliance to HOA submissions and final inspections. Our Montana crews have installed hundreds of patio roofs and covered decks, and we bring the same attention to detail to every post, beam, and bracket. You choose the style we’ll handle the rest.

Covered decks make Montana homes more livable year-round. You’ll enjoy morning coffee in the fall, shaded barbecues in the summer, and snow-free steps in winter. Our covered structures are designed for real use not just looks. Whether you want a quiet retreat or a hosting space, we make sure your new roofed deck works with your lifestyle and lasts for years.
All-season builds for year-round outdoor use
Ideal for seating areas, outdoor dining, or spas
Great ROI for resale or long-term comfort
From wind-prone ridges near Livingston to heavy snow zones in Kalispell, we tailor every covered deck to local conditions. That means deeper footings, stronger bracing, and steeper pitches when needed. We factor in orientation, runoff, sun angles, and ventilation. No prefab shortcuts—just roofs and covers that work exactly where they’re built.
Homeowners across Montana ask us how to improve outdoor comfort without building walls. Here are the most common questions about covered decks:
Often, yes. If the frame is strong enough and the footing supports it, we can retrofit a patio roof or pergola.
Pergolas offer partial shade with an open-air look. Roofs provide full protection from sun, snow, and rain.
We build to your region’s required snow load—often 40–100+ pounds per square foot.
Yes. Covered decks add curb appeal, function, and resale value—especially in Montana’s 4-season climate.
