Understanding Building Permissions and Structural Capacity
Before selecting any materials, the first step for any elevated deck tile project is to understand the local building codes and obtain necessary permissions. In Salt Lake City, this typically involves contacting your building department to inquire about permits required for exterior modifications, especially on rooftops or balconies. You may need to provide drawings and specifications for your proposed installation.
Crucially, you must verify the structural capacity of your existing rooftop or balcony. Elevated structures are designed to bear a specific live and dead load. Adding deck tiles, furniture, planters, or occupants increases this load. Consult with a structural engineer to confirm that the existing structure can safely support the additional weight. This step is non-negotiable for safety and compliance.
Your building management or homeowner's association (HOA) will also likely have specific rules or design guidelines for exterior changes. Confirm any restrictions on materials, colors, or installation methods before making product selections.
Measuring Door Thresholds and Vertical Clearance
One of the most common challenges on balconies and rooftops is navigating door thresholds. The finished height of your deck tile surface must be below the bottom of any exterior doors to prevent water ingress and allow for proper door operation. Measure the available vertical clearance from the existing surface to the bottom of the door threshold.
Deck tiles typically come in two main sizes: 12 x 12 inches and 24 x 24 inches. Both have a specific thickness. When combined with a support system (such as sleepers or pedestals), the total assembly height can vary. For example, a 12 x 12 inch tile or a 24 x 24 inch tile will have a base thickness that adds to the overall height. Account for this total height when comparing it to your door thresholds.
A common solution for low thresholds is to use a low-profile pedestal system or directly lay tiles on a protective membrane if the surface is perfectly level and drainage is assured beneath the tiles. Always ensure sufficient slope for water to drain away from the building and door openings.
Planning for Drainage and Waterproofing
Proper drainage is paramount on any elevated outdoor space. Rooftops and balconies are designed with a slight slope to direct rainwater to drains or scuppers. Your deck tile installation must not impede this critical water flow. The assembly beneath the tiles needs to allow water to pass freely to the existing drainage system.
Consider using pedestal systems that elevate the deck tiles, creating a void beneath for water to flow. This also allows for inspection and maintenance of the waterproofing membrane below. If laying tiles directly, ensure the existing surface has adequate slope and that the tiles themselves do not trap water.
For projects on a roof, the integrity of the waterproofing membrane is vital. Do not puncture or damage the membrane during installation. If using a pedestal system, choose pedestals with broad bases that distribute weight evenly and protect the membrane. Ensure that all drains, scuppers, and overflow points remain fully accessible and functional after the deck tiles are installed.
Selecting the Right Deck Tile Material
Lumber Plus offers deck tiles in various hardwood species, each with distinct characteristics suitable for outdoor use. Your choice will depend on aesthetics, desired durability, and maintenance preferences.
Ipe deck tiles are known for their deep chocolate tones and exceptional hardness. This material is a classic choice for a rich, durable appearance. Garapa deck tiles offer warm golden tones, ideal for creating a brighter, more open feel on terraces and balconies. Cumaru deck tiles feature a rich reddish-brown grain, providing strength and character similar to other tropical hardwoods.
All these hardwood options are designed for outdoor exposure. Consider how the natural color variation and grain will complement your building's exterior and the surrounding Salt Lake City landscape. Remember that all natural wood will weather and change color over time if left untreated. Regular cleaning and occasional reapplication of a UV-inhibiting oil can help maintain the original color.
Worked Example: Balcony Deck Tile Project
Let's consider a hypothetical balcony project in Salt Lake City with the following conditions:
Balcony Dimensions: 10 feet long x 4 feet wide. Existing Surface: Concrete slab with a slight slope towards a perimeter drain.
Project Goal: Install 24 x 24 inch Garapa deck tiles to create a uniform, elevated surface.
1. Area Calculation: The balcony area is 10 ft * 4 ft = 40 square feet. Since each 24 x 24 inch tile covers 4 square feet, we would need 40 / 4 = 10 tiles for full coverage.
2. Layout Planning: For a 10-foot by 4-foot space, a 24-inch (2-foot) tile fits perfectly across the 4-foot width (2 tiles). Along the 10-foot length, you would need 5 tiles (10 feet / 2 feet per tile). This results in a grid of 5 tiles by 2 tiles, totaling 10 tiles. No cuts would be needed for the main area.
3. Height Check: Garapa 24 x 24 inch deck tiles have a certain thickness. This means a very low-profile support system or direct-lay application might be feasible if the surface is truly level and allows for drainage.
4. Drainage: Even with direct-lay, ensure the existing slope of the concrete slab is maintained and water can flow freely to the perimeter drain. If using pedestals, verify that the pedestal bases do not block the drain and allow full water flow underneath the tile surface. In this example, the simple grid avoids complex cuts around the drain, but careful placement of pedestals is still required.
This example illustrates the importance of exact measurements and considering all components of the assembly before ordering.
Complementary Products for Your Project
Beyond the deck tiles themselves, consider these products to complete your elevated outdoor space:
Pedestal Systems: Essential for creating a level surface over sloped membranes and allowing for drainage and access beneath the tiles. Various heights are available to accommodate different threshold clearances and leveling needs. Ensure the pedestals are compatible with your chosen deck tile size and can support the expected load.
Edge Finishing: For a polished look, consider edge trim pieces or fascia boards to finish the exposed sides of your deck tile installation. This is particularly important for balconies where the tile edges are visible from below.
Hardwood Cleaners and Sealers: To maintain the beauty of your hardwood deck tiles, especially in Salt Lake City's climate, invest in appropriate cleaning and sealing products. These help protect the wood from UV exposure, moisture, and dirt, extending its life and preserving its appearance.
Outdoor Lighting: Integrate discreet lighting into your deck tile design to enhance usability and ambiance during evening hours. Consider low-profile fixtures that won't interfere with foot traffic or drainage.

Questions to help you decide
Can deck tiles be installed directly on a rooftop membrane?
While it's technically possible, it's generally not recommended to lay deck tiles directly on a rooftop membrane without a proper support system. A pedestal system elevates the tiles, allowing for crucial drainage and airflow beneath, which protects the membrane and prevents water pooling. Directly laying tiles can trap moisture, potentially damaging the membrane and voiding warranties. Always consult with a roofing professional and the membrane manufacturer.
How do I ensure proper drainage on my balcony with deck tiles?
To ensure proper drainage, the existing slope of your balcony or rooftop must be preserved. If using a pedestal system, the pedestals can be adjusted to create a level surface for the tiles while maintaining the underlying slope for water flow. Ensure that all existing drains, scuppers, and weep holes are not obstructed by the deck tile installation and remain fully accessible for cleaning and maintenance. Never create a dam that prevents water from reaching the intended drainage points.
What maintenance is required for hardwood deck tiles in Salt Lake City?
Hardwood deck tiles, like Ipe, Garapa, and Cumaru, are durable but benefit from regular maintenance. In Salt Lake City's climate, periodic cleaning to remove dirt, pollen, and debris is important. If you wish to maintain the original color of the wood, a UV-inhibiting oil should be applied annually or as needed. Otherwise, the wood will naturally weather to a silver-gray patina over time. Always follow the manufacturer's recommendations for cleaning and sealing products.
