Dock Types Guide
A boathouse or covered dock puts a roof over your slip and deck so the boat, lift, and gathering space stay shaded and dry. It runs from a simple open-sided shade roof to a fully enclosed boathouse with walls and doors, all on the same piling-and-frame structure as a standard dock. The shade does more than keep you cool — it shields the boat and decking from UV and rain, protecting both for years. It's our highest-feature dock, starting around $75 per square foot of deck area plus the roof. We build, replace, and repair boathouse docks across Texas, Illinois, and Indiana — from our Houston base (base #1, Houston + 120 miles) and our Chicago base serving all of Illinois and Indiana.
Best for: protecting a boat and deck from sun, rain, and weather; boat-lift slips.
Lifespan: 20–30 years for the dock; the roof shields and extends what's beneath it.
Roof options: flat ($28/SF), gable ($38/SF), hip ($48/SF).
Covered and enclosed boathouse docks that shelter the boat, lift, and deck from sun and weather — flat, gable, or hip roofs.
A boathouse dock is a standard piling dock with a roof structure built over it. The pilings and framing are sized to carry not just the deck and boat but the posts, roof, and wind load of the cover; posts rise from the dock to support roof trusses; and the roof — flat, gable, or hip — sheds water clear of the slip. Open-sided, it's a covered dock that gives shade and rain protection; add walls and doors and it becomes a true boathouse that encloses the boat. A boat lift almost always pairs with the cover, so the hull sits up out of the water and under the roof between uses — the combination that best preserves a boat.
A covered dock is the right call when protecting the boat and getting shade matter as much as moorage — and on a sunny Texas lake or a storm-prone shoreline, that's most owners with a boat worth covering. The trade-offs are cost, height, and a closer permit review. If you just need to tie up and swim, an open wood piling or floating dock costs much less; if you want open-air lounging instead of a roof, a double-decker dock gives you a sun deck. Compare every option on our dock & boathouse hub.
Per square foot of deck (plus roof by covered area), a standard boathouse dock is built from:
| Component | Typical spec | Role |
|---|---|---|
| Pilings | Upsized CCA timber, driven | Foundation sized for deck + roof + wind load |
| Dock framing & deck | 2×12 treated framing, treated/composite deck | The walking and boarding platform |
| Roof posts & trusses | 6×6 posts, engineered trusses | Raise and carry the roof |
| Roof | Flat, gable, or hip; metal or shingle | Sheds water and shades the slip |
| Boat lift | Cantilever or piling-mounted | Holds the boat up under the roof |
| Optional enclosure | Walls, doors, storage | Turns a cover into a full boathouse |
Our crews follow a consistent sequence so the cover carries wind and weather for decades:
A covered or boathouse dock runs about two to four weeks on site once permitting clears — longer with a full enclosure.
The freshwater piling structure lasts 20–30 years, and the roof and enclosure are maintained on their own cycle — re-roof, re-fasten trim, re-seal. The happy irony of a covered dock is that the roof extends the life of the decking and boat beneath it by blocking UV and rain. Maintenance is the dock plus the building: inspect roof fasteners and flashing after storms, keep the lift serviced, and check posts and truss connections.
On boathouse inspections, the warning signs span the dock and the structure above it:
Roof and structural repairs are usually targeted, not a rebuild. If the roof is becoming a maintenance burden and you'd rather have open-air space, compare a double-decker dock.
Covered boathouse docks start around $75 per square foot of deck area (labor and materials), with the shore approach about $150 per linear foot. The roof is priced separately by covered area: about $28/SF for a flat roof, $38/SF for a gable, and $48/SF for a hip roof. A boat lift and any enclosure add to the total. Deck size, roof type and area, and the level of enclosure drive the final number. Demolition of an old structure is a separate line item.

Every boathouse dock follows the same disciplined sequence: structural design for deck and roof load, pile driving, dock framing and decking, roof posts and trusses, the roof, then enclosure, lift, and mooring. Because a covered or enclosed structure adds height and footprint, it almost always requires a closer review than an open dock — federal review (USACE Section 10 / Section 404) plus state and local approval, such as TCEQ/GLO in Texas, the IDNR Office of Water Resources in Illinois, and the Indiana DNR, and sometimes lake or HOA rules specific to covered docks. We handle the permitting and agency coordination so the project moves without stop-work surprises.
Covered docks are especially popular where strong sun or storms make boat protection a priority. We run two regional bases so crews stay close to the job and to the permitting authorities that review it:
For open-air lounging instead of a roof, a double-decker dock is the related option; for the most basic moorage, an open wood piling dock costs less.
Common questions we answer for lakefront owners — covered dock vs boathouse, cost per square foot, roof options (flat, gable, hip), lifespan, boat lifts, repairs, build time, and permits.
A covered dock is an open-sided dock with a roof over the slip and deck for shade and weather protection. A boathouse adds walls and often doors to fully enclose the boat. Both sit on the same piling-and-frame structure as a standard dock; the difference is how much of it is roofed and enclosed. We build everything from a simple shade roof to a fully enclosed boathouse.
A covered boathouse dock starts around $75 per square foot of deck area installed, the highest-feature dock we build, with the shore approach about $150 per linear foot. The roof is priced on top of that by covered area: about $28 per square foot for a flat roof, $38 for a gable, and $48 for a hip roof. Adding a boat lift and enclosure raises the total further.
A flat (or low-slope) roof is the most economical at about $28 per square foot and gives basic shade. A gable roof (~$38/SF) sheds rain and snow better and gives a more finished look. A hip roof (~$48/SF) sheds water on all sides and handles wind best, which suits exposed and storm-prone sites. We match the roof to your weather, budget, and the look you want.
On freshwater pilings, the dock structure lasts about 20–30 years, and the roof and any enclosure are maintained on their own cycle (re-roofing, fasteners, trim). Ironically, a covered dock often keeps its decking and boat in better shape than an open dock because the roof shields them from UV and rain — shade extends the life of what's underneath it.
Most boathouse and covered docks include a boat lift — it's the natural pairing. The roof shields the boat from sun and rain while the lift keeps the hull out of the water between uses, which together dramatically reduce maintenance and protect the boat's value. We integrate the lift, slip, cleats, and a ladder into the covered structure.
Yes. The dock below is repaired like any piling dock, and the roof and enclosure are repaired like any roofed structure — replace damaged roofing or panels, re-fasten trim, and re-seal. Roof repairs after wind or storm damage are among the most common boathouse repairs, and they're usually straightforward and targeted.
A covered or boathouse dock takes longer than an open dock because of the roof framing and any enclosure — figure about two to four weeks on site once permitted, depending on size, roof type, and whether walls and a lift are included. Pile setting and roof framing are the time-consuming steps.
Yes, and a covered or enclosed structure usually faces closer review than an open dock because of its height, footprint, and visual impact — some lakes and HOAs have specific rules on covered docks and boathouses. A dock triggers federal review (USACE Section 10 / 404) plus state and local approval. We manage the permitting and agency coordination for you.
