Pergola Covered Deck: Lattice FullWrap Cantilever Roof
Most people picture a pergola as a flat grid of beams overhead — a nice frame for the sky, but not much of a plan for the sun. You get the open, airy feel of timber above you, or you get real shade. Not both.
The cantilever FullWrap™ roof changes that equation. By extending the roof past the posts and wrapping the beam and rafter profiles around the entire structure, you get directional shade that tracks with where people actually sit — without losing the sense of being outdoors. It is one of those design moves that sounds small on paper and feels obvious the first afternoon you spend under one.
Some of our clients take it a step further with a slanted roof pergola kit — angling the entire roof plane for rain runoff and even more aggressive shade coverage. Whether you go with a flat cantilever, a slanted pitch, or a lattice top, the FullWrap finish and cantilever overhang are the features that make the biggest difference in how the space actually feels.
What Makes a Cantilever Roof Different
On a standard pergola, the roof sits directly above the posts. The shade footprint and the structural footprint are the same rectangle. That works fine — until you try to arrange furniture, plan foot traffic, or push the shade toward the wall where people actually tend to gather. Western Timber Frame engineers the cantilever overhang so the beams carry the extra reach without adding posts underneath.
A cantilever roof extends the roof plane beyond the posts. It reaches out — toward the house, toward the seating area, toward wherever the shade matters most — while the posts stay further back, out of the way. The result is a pergola that covers more ground with fewer obstacles in the space beneath it.
Here is the counterintuitive part: a pergola that extends past its own posts actually gives you more usable room underneath, not less. Most people assume a bigger footprint means more posts and more clutter. The cantilever does the opposite. It separates the shade footprint from the structural footprint, so the area you use every day feels wider and more open than the posts alone would suggest. Western Timber Frame draws each design in 3D first, so a homeowner can see where the posts land before ordering.
FullWrap: Finished From Every Angle
Most pergola kits have a front and a back. The beam ends and rafter tails look great from the primary sightline, and then you walk around the side and find raw cuts or unfinished profiles staring back at you. It is a detail most people do not think about until they are standing in the wrong spot at a dinner party.
The FullWrap design eliminates that. Beam and rafter end profiles — Roosevelt, Champion Step, Craftsman, whatever style fits the build — wrap around the entire structure. Every sightline is a finished sightline. Walk a full circle around a FullWrap pergola and you will not find the angle where the builder stopped caring. That angle does not exist.
When you combine FullWrap with a cantilever roof, the effect is even more pronounced. The overhang creates depth and shadow lines that draw the eye along the roofline. If those profiles stopped abruptly at the post line, the cantilever would look like an afterthought. With FullWrap, the whole structure reads as one deliberate piece of design.
Lattice Roof: Shade That Moves With the Day
A solid roof creates a hard edge between sun and shadow. A lattice roof does something more interesting. As the sun tracks across the sky, the light patterns shift — dappled in the morning, deeper in the afternoon, soft and warm toward evening. The shade is real, but it breathes.
Pair lattice with a cantilever overhang and you get directional shade that changes character throughout the day. Morning coffee feels different from an evening glass of wine under the same roof — the lattice makes sure of that. It is the kind of detail that people notice without quite knowing what they are noticing, which is usually the mark of good design.
Featured Build: A Covered Deck in Pleasant Grove, Utah
A family in Pleasant Grove loved their first Western Timber Frame pergola — an 18-by-27-foot 8000 Series installed over the concrete patio with a fire pit and dining area — so much that they came back for a second one. This time, over the solid wood deck just off the back door.
The second structure is a 21-foot-2-inch by 27-foot Douglas fir pergola from the 8000 Series, with a 15-foot-2-inch by 23-foot post-to-post footprint. Free-standing on the deck, finished in Rich Sequoia satin stain to match the first build across the yard. Classic style knee braces anchor the connections, and Roosevelt style beam and rafter end profiles wrap the entire structure — FullWrap, of course.
The posts stand 12 feet tall. From the deck surface to the bottom of the lowest beam, there is 10 feet 10 inches of clearance — an almost cathedral-like openness that makes the space feel generous without being cavernous. The cantilever roof faces the house, pushing lattice shade right where the family sits. The pergola shipped drilled for power with an outlet and light switch wired in. Metal candle lanterns handle the rest after sunset.
Two pergolas, one yard. Different zones, same warmth, same Rich Sequoia finish pulling it all together.
More Cantilever and FullWrap Builds
The cantilever FullWrap™ design works across a wide range of sizes, timber species, stain finishes, and settings. Here are a few more examples from Western Timber Frame™ projects around the country.
Cantilever Roof Design Example – Image Shown for Feature Reference, Not Stain Color
Cantilever Roof:
A cantilever roof extends past the posts instead of sitting directly above them. That single design move does more than you would expect — it pushes shade toward the house wall where the seating actually lives, while keeping the posts further out and out of the way. The footprint you walk around in feels bigger than the footprint the posts define. Most people assume more coverage means more posts and more clutter. The cantilever does the opposite.
FullWrap™ Roof Design Example – Image Shown for Feature Reference, Not Stain Color
FullWrap™ Roof:
Most pergola kits have a good side and a side the builder hopes you will not look at too closely. The FullWrap™ design eliminates that problem entirely. Beam and rafter end profiles wrap around the full structure — every corner, every sightline, every angle you did not plan for when guests wander around the yard. Walk a full circle around a FullWrap pergola and you will not find the spot where the finishing stops. That spot does not exist.
Every one of these started the same way — a conversation about how the space would actually be used, what direction the sun comes from, where the furniture goes, and what the sightlines look like from inside the house. The cantilever angle and the FullWrap™ finish are not catalog upgrades. They are design decisions that come out of that conversation.
Want a Slanted Roof? You Can Do That Too
Everything above — the cantilever overhang, the FullWrap™ profiles, the lattice shade — works with a flat roof plane. But some spaces call for a pitched or slanted roof pergola kit instead. A slanted roof adds rain runoff, steeper shade angles, and a roofline that ties into the pitch of the house behind it.
Western Timber Frame™ builds both. The cantilever and FullWrap features carry over to a slanted configuration — same pre-cut joinery, same finished profiles from every angle, same kit that goes up in a day. The roof pitch is a design decision that comes out of the consultation, not a separate product line.
What Ships in the Kit
Every Western Timber Frame pergola kit ships with pre-cut timber and joinery, all structural hardware, and a pre-applied premium stain finish — no separate stain bill, no finishing weekends in the driveway. Engineering drawings, assembly guides, reference photos, and phone support during install are all included.
The pre-cut joinery is what makes a structure this size go up in a day rather than dragging out over a week. Most of the thinking happens in the shop before the kit ships. On-site, it is mostly assembly.
That speed surprises people. They expect a multi-day build and get an afternoon. The gap between the expectation and the reality is itself a kind of proof — the engineering in the joinery is doing more work than it looks like from the outside.

The Real Test of a Pergola Kit
A pergola has done its job when you stop noticing the structure and start noticing how much more time you spend outside. String lights on a summer evening. Morning coffee with the lattice throwing patterns at your feet. The moment someone pulls up a second chair without being asked.
The cantilever roof and the FullWrap finish are what make that happen faster. More shade where you need it. A finished look from every angle. A structure that feels like it was always part of the house — because the design conversation started with the house, not a catalog page.
Western Timber Frame has delivered 7,000+ structures to all 50 states.
