Understanding Building Permissions and Structural Capacity
Before selecting any materials, confirm the necessary building permissions and review the structural capacity of your specific rooftop or balcony. Elevated structures, especially those on commercial buildings or multi-unit residences, often have specific load-bearing limits. Adding deck tiles, furniture, planters, and occupants contributes to the overall weight.
For any significant modification, consult with a structural engineer or the building management to ensure the proposed installation falls within safe load parameters. This step is critical for safety and compliance, particularly in urban environments like Des Moines where building codes are in place to protect property and people.
Navigating Door Thresholds and Vertical Clearance
Deck tiles, especially when installed on a pedestal system, will add height. Measure the available clearance carefully at all door openings.
Consider the height of the deck tile itself, which can be 12" x 12" or 24" x 24" squares (Source S1). If using a pedestal system, account for the pedestal base and any adjustable height components. The final surface of the deck tiles should be lower than the door threshold to prevent water intrusion and allow for easy door operation. In some cases, low-profile deck tiles or specific pedestal types may be necessary.
Drainage and Water Management
Proper drainage is paramount on any rooftop or balcony. Water must be able to flow freely to existing drains or off the edge of the structure without pooling. Deck tiles are typically installed with small gaps between them, allowing water to pass through to the underlying surface.
If you are installing over a waterproof membrane, ensure the membrane's integrity is not compromised and that it directs water efficiently to drainage points. Avoid creating obstructions that could lead to standing water, which can damage the waterproofing and create slip hazards. Regular inspection of drains and clear pathways for water are essential.
Choosing the Right Deck Tile Material and Size
Lumber Plus offers deck tiles in various hardwood species and sizes, each with distinct characteristics. Ipe deck tiles are known for their deep chocolate tones, while Garapa offers warm golden hues, and Cumaru presents rich reddish-brown grain (Source S1). The aesthetic appeal and natural durability of these hardwoods make them suitable for outdoor applications.
Deck tiles are available in 12" x 12" and 24" x 24" dimensions (Source S1). The 12" x 12" size is compact for smaller areas or complex layouts, while the 24" x 24" size is suitable for larger, open surfaces, resulting in fewer seams (Source S1). Consider how the tile size will interact with the dimensions of your specific balcony or rooftop, especially around fixed elements or edges.
Worked Example: Planning a 10' x 12' Balcony with 24" x 24" Ipe Deck Tiles
Let's consider a hypothetical balcony project in Des Moines measuring 10 feet (120 inches) by 12 feet (144 inches).
First, measure the precise dimensions. For a 10' x 12' balcony, the total area is 120 square feet. Using 24" x 24" (2' x 2') deck tiles, each tile covers 4 square feet (Source S1).
Along the 10-foot (120-inch) width, you would need 120 inches / 24 inches/tile = 5 tiles. Along the 12-foot (144-inch) length, you would need 144 inches / 24 inches/tile = 6 tiles. This means a total of 5 x 6 = 30 tiles for a perfect grid without cuts. In a real-world scenario, you may need a few extra tiles for cuts around obstacles or for future replacement.
Ensure the balcony has adequate slope for drainage and that existing drains are easily accessible and not obstructed by the new tile installation. Consider the natural color variation of Ipe, which offers deep chocolate tones (Source S1), and how this will complement your outdoor furniture and building facade.
Maintenance and Long-Term Considerations
Regular maintenance helps preserve the appearance and longevity of your deck tiles. Hardwood deck tiles can be cleaned with a broom or hose to remove debris. To retain their original color, some hardwood species may benefit from periodic application of a UV-inhibiting oil.
For projects in Des Moines, consider seasonal changes. While hardwood is durable, clearing snow and ice promptly helps prevent prolonged moisture exposure. Ensure that any cleaning solutions or de-icing agents used are safe for your chosen hardwood species and will not harm the underlying waterproofing membrane.
Before you order
- Verify building permissions and structural capacity for your rooftop or balcony.
- Measure all door thresholds to determine maximum allowable deck tile height.
- Assess existing drainage and plan for unobstructed water flow.
- Select deck tile species (Ipe, Garapa, Cumaru) and size (12" x 12" or 24" x 24") based on aesthetics and project dimensions.
- Consider the assembly method: direct lay or pedestal system, and its impact on height and drainage.
- Plan for edge transitions and any necessary cuts around columns or railings.
- Outline a maintenance schedule for cleaning and preserving the hardwood.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.

Questions to help you decide
Do I need a building permit for deck tiles on my Des Moines balcony?
It depends on the scope of your project and the building type. Minor, non-structural installations on private balconies may not require a permit, but any changes to a rooftop, common area, or modifications affecting structural integrity or egress almost certainly will. Always consult with the City of Des Moines building department or your building management before starting work.
Can deck tiles be installed directly on a waterproof membrane?
Deck tiles can be installed over a waterproof membrane, but it's crucial to ensure the membrane is protected and that water can still drain effectively. Pedestal systems are often used in these scenarios to elevate the tiles, allowing water to flow underneath to the existing drains and preventing direct contact that could damage the membrane.
What's the difference between Ipe, Garapa, and Cumaru deck tiles?
These are different hardwood species, each offering unique aesthetics and properties. Ipe is known for its deep chocolate tones, Garapa for warm golden hues, and Cumaru for rich reddish-brown grains (Source S1). All are durable for outdoor use, but their appearance and density vary. It's recommended to compare samples to see which best fits your design preference.
