WHAT WE COVER
Rooftop Deck Builder Services
Across Seattle
Define all six parts of the Seattle rooftop deck builder scope before work begins. Your written estimate lists the included work, and your workmanship warranty terms are written into your agreement.
We spell out the project scope in a written estimate before work starts, and your warranty terms are written into your agreement.
01 / ROOFTOP DECK BUILDER
Structural Load Review
Begin with an engineer’s review of the roof and supporting structure. Seattle SDCI deck guidance identifies a minimum deck live-load design of 60 psf, approximately 293 kg/m². The actual building, occupancy, dead load, wind and additional equipment still need a project-specific design; this is not a universal approval for every Washington rooftop.
02 / ROOFTOP DECK BUILDER
Pedestal-Paver Systems
Compare pedestal systems such as Buzon or Wausau Tile with the pavers, slope and roof membrane. Height range, load rating, perimeter restraint and protection pads vary by system, so we match them to your roof. Avoid assuming that an unpenetrated membrane cannot be damaged.
03 / ROOFTOP DECK BUILDER
Rain Escape Drainage
Coordinate runoff, drains, scuppers, downspouts and maintenance access with the roofing professional. Trex RainEscape is an under-deck drainage product. Confirm suitability with the manufacturer and project designer.
04 / ROOFTOP DECK BUILDER
IPE & Composite Decking
Compare IPE, Trex Transcend composite and AZEK PVC against the roof’s load allowance, exposure, fire requirements where applicable and installation conditions. Salt air, UV and freeze-thaw performance depend on the exact material and assembly; a PVC weight advantage cannot establish structural suitability by itself.
05 / ROOFTOP DECK BUILDER
Code-Compliant Railings
Cable railing and glass balustrades can preserve views, but guards need designed attachment and applicable height, opening and load criteria. Guard height, such as 42 inches, and any through-paver anchorage are set to the criteria that apply to your project. Coordinate all connections and penetrations with the structure and roofing system.
06 / ROOFTOP DECK BUILDER
SDCI Permit & Final Inspection
Define structural calculations, drainage plans, guard details and any further SDCI documents required for the project. Permit fees vary with the scope of the project, and we go over them with you during planning. Confirm submission responsibilities, city fees and final inspections; roof-deck permit requirements are explained in Seattle SDCI deck guidance.

WARNING SIGNS
Can Your Roof
Hold a Deck?
A usable roof area is only the beginning. Review all seven planning conditions with the relevant professionals before treating the building as ready for a rooftop deck.
Deck materials and construction details to consider for your project.
01
Flat roof or low-slope membrane in good condition
Review the flat or low-slope roof membrane, drainage, remaining condition and roof warranty. A visual impression of good condition is not a substitute for the roofing assessment.
02
Structural engineer confirms load capacity for live use
Have a structural engineer assess the intended use, dead and live loads, connections and the building below. A roof’s existing design should not be assumed to support occupants and decking.
03
Stair or hatch access to roof already exists
Evaluate stairs or a hatch as part of the access, egress and safety design. Existing access does not automatically meet the requirements for an occupied rooftop.
04
Building is 4 stories or less (or has elevator access)
Consider material delivery and construction access on a low-rise or elevator-served building. We review your building’s access and structure on site before we write the estimate.
05
Want condo or townhome outdoor living space
Confirm ownership, common-area boundaries and required association approvals for condo or townhome outdoor living space.
06
View deck for Capitol Hill or downtown Seattle high-rise
For a Capitol Hill or Downtown Seattle view deck, assess wind, guards, privacy, access and the specific building classification alongside the view.
07
Replacing failed wood deck on existing rooftop
Investigate why the old rooftop wood deck failed. Coordinate demolition with protection and inspection of the roof before choosing a replacement assembly.
Discuss your rooftop deck builder options.
Describe the property, existing deck and preferred timeline. We’ll confirm a visit time that works for you.

SEATTLE PERMITS
Rooftop Deck Permits
in Seattle
Every roof deck in Seattle needs a permit. SDCI treats a roof deck as an addition or alteration, so it needs the full construction permit rather than the quick field-inspection one. We tell you at the free estimate what your roof needs.
Source: Seattle SDCI deck requirements.
01 / ROOF DECKS
Always need a permit
A deck built on top of part of the building needs a permit no matter its size or height.
02 / FULL PERMIT
Addition or alteration permit
Roof decks go through the full construction permit, not the subject-to-field-inspection permit most ground decks use.
03 / GUARDRAILS
36 inches or taller
Required when the deck is more than 30 inches above a lower roof or the ground. Glass guardrails have their own rules and may need an engineer.
04 / STAIRS
Riser 7-3/4 inches or less
Treads at least 10 inches deep and 36 inches wide, with a handrail once there are four or more risers.
We check the permit at your estimate.
If your project needs one, it goes into your written scope.

Built for Seattle
Rain, Wind and Salt Air
Rain, evergreen shade, seasonal freeze–thaw conditions and Puget Sound salt exposure all belong in a Seattle rooftop deck builder assessment. Moss and slow drying can hide moisture problems around board ends and structural connections.
For shaded or north-facing decks in Fremont and Ravenna, inspect moisture retention and ventilation. Waterfront properties around Magnolia and Alki may need additional attention to corrosion. Sloped or elevated sites in Queen Anne and Capitol Hill call for a close review of supports and access. We confirm the actual conditions at each address.
- Compatible stainless or coated fasteners. Select for the lumber treatment, connector and exposure.
- Appropriately treated framing. Use ground-contact-rated material where the assembly and exposure require it.
- Joist and ledger moisture protection. Detail flashing, drainage and protection tape as part of the repair.
- Finishes suited to the site. Confirm any marine-grade or waterfront coating against the product’s approved uses.
Read the background on deck construction and repair and the Seattle SDCI deck requirements.
Plan for repeated Seattle rain, shade and drying conditions at the actual property. Specify corrosion-compatible stainless or coated fasteners as part of the complete lumber, connector and exposure design.

Rooftop decking in Seattle starts at $28 per square foot and railing at $20 per linear foot, with up to 25% off qualifying projects. Your exact price comes from the free on-site estimate.
We can discuss a rooftop deck estimate with engineering, roofing coordination, access, pedestal or deck system, railings, lighting and permits identified separately. For a 200 sq ft / about 19 sq m layout, compare pedestal pavers with the complete assembly; cable rail, LEDs and a pergola need their own scope.
The building’s structure, roof condition and access help determine your rooftop installation price. Let’s work through those details before selecting the materials and optional features.
Often, yes, when the roof structure can carry it. Every Seattle roof deck needs a permit, and some need an engineer. We check the structure and access at the free estimate.
Yes. The on-site estimate is free and comes with no obligation. You get a written price and decide on your own time.
Tell us the size of the deck and what you see, and send photos if you have them. That is enough to talk through the likely scope on the phone. The exact number comes from the free visit, because rot, footings and framing hide under the boards.
If your project needs a Seattle permit, we tell you at the estimate and include it in your written scope. Most decks need only a subject-to-field-inspection permit from Seattle SDCI.
We can plan rooftop construction in sequence: roof preparation and layout, the approved support and surface system, then railings, lighting and inspections. Engineering, permit review and material ordering belong in the overall schedule before site work begins.
Our schedule requires the actual permit route, association review, material availability and contractor commitments. Roof work, delivery access and weather can change the sequence.
No. The building needs suitable structural capacity, a compatible roof assembly, lawful access and project approvals. SDCI’s 60-psf deck live-load guidance is one design requirement, not a complete structural check.
For a Capitol Hill or Queen Anne townhome, we can start with the building and an engineer’s assessment. Construction date and neighborhood do not establish roof-deck eligibility; the review needs the actual loads, structure and proposed layout.
A properly specified pedestal system can avoid many deck-surface penetrations and allow pavers to be lifted for roof access. Protection, loading, drainage and any guard connections still require coordination.
We can discuss roof protection, manufacturer-approved details and access for inspection and repairs. Coordinate the deck support system with the roofing requirements so the membrane remains serviceable; no assembly makes every risk of roof damage disappear.
IPE hardwood, TimberTech AZEK PVC and Trex Transcend composite are options to evaluate against the actual building and roof system. Compare weight, fastening, exposure, maintenance and written warranty.
We can compare IPE, AZEK, Trex and cedar against your roof’s structural capacity, exposure and care preferences. Review the exact product specifications, support assembly and warranty together before choosing the deck surface.
Check the governing association documents and obtain required approval before committing to work. Roof areas may be common property, and sequencing of association and city review varies.
We can discuss the drawings, structural reports and material specifications your HOA requires. Agree who prepares any professional stamps, then obtain the board’s review timetable before setting the construction dates.
Our Washington contractor registration is #DBSTTLE287G8; verify it with Washington Labor & Industries. It is also listed at the bottom of every page.
We carry $1 million in general liability insurance, with a certificate available for your rooftop deck project, and we are a BBB Accredited Business. Your written estimate spells out the scope before work starts.
Ask for written coverage of framing, ledger attachment, footing connections, railings and stairs, together with exclusions, claim steps and any transfer rights on sale. Talk with us about the workmanship coverage for your project. Only the contractor’s written warranty establishes the duration and coverage.
We can review Trex, TimberTech and IPE material coverage separately from workmanship coverage. Match the exact product, collection, purchase date and installation requirements to the manufacturer’s current warranty, then confirm the contractor’s written terms for the agreed work.
