Understanding Your Elevated Surface: Balcony vs. Rooftop
While both balconies and rooftops are elevated, their underlying structures and intended uses often differ, impacting your deck tile project. Balconies are typically cantilevered or supported extensions from a building, often with a finished underside visible from below. Rooftops, especially flat roofs, are primarily structural elements designed to shed water and protect the building, sometimes with an additional membrane system.
For balconies, key considerations include the existing floor material (often concrete or a waterproofed surface), the height of door thresholds, and the weight capacity of the structure. Rooftop projects, particularly those over occupied spaces, require careful attention to the waterproofing membrane, drainage systems, and the potential need for a pedestal system to protect the membrane and create a level surface over a sloped roof. Always consult with a structural engineer or building professional to confirm the load-bearing capacity for any deck tile installation on an elevated structure.
Your project's specific location within Saint Paul, MN, and the building type (e.g., residential condo, commercial building) will influence the applicable building codes and approval processes. Start by understanding the existing conditions and consulting with your building's management or a qualified contractor.
Measuring Door Thresholds and Vertical Clearances
One of the most critical measurements for any elevated deck tile project is the door threshold height. The finished height of your deck tile surface must allow for adequate clearance beneath any doors opening onto the balcony or rooftop. Insufficient clearance can prevent doors from opening fully or cause them to drag, leading to damage or safety issues.
Measure the vertical distance from the existing surface (e.g., concrete slab, waterproof membrane) to the bottom of the door sweep or the lowest operable part of the door. This measurement dictates the maximum permissible height of your deck tile assembly, including any support system (such as pedestals or sleepers).
Also, consider any other fixed elements like railings, low walls, or existing drainage grates. The deck tile system should ideally finish below the top of these elements, or integrate cleanly with them, to maintain functionality and aesthetics.
Drainage and Water Management
Effective drainage is paramount for rooftop and balcony deck tile installations. Water must be able to flow freely off the surface and into existing drains or over the edge without pooling. On sloped rooftops, deck tiles often require a pedestal system to create a level walking surface while allowing water to flow underneath along the original slope to the drains.
Ensure that the deck tile layout does not obstruct existing drains or scuppers. Access to these drainage points for cleaning and maintenance should be preserved. If using a pedestal system, verify that the pedestals are designed to maintain proper water flow beneath the tiles.
For balconies, where the surface might be flatter, ensure any standing water can evaporate or drain away. Avoid creating areas where water can collect under the tiles, as this can lead to moisture issues or accelerate wear on the underlying surface. Consider the prevailing weather patterns in Saint Paul, MN, including snowmelt and heavy rainfall, when planning your drainage strategy.
Selecting Deck Tile Species and Sizes
Lumber Plus offers hardwood deck tiles in various species and sizes, each with distinct characteristics suitable for different project needs. The choice of species can influence both the aesthetic and the long-term performance.
Ipe deck tiles are known for their deep chocolate tones and exceptional hardness, offering a classic hardwood look. Garapa deck tiles provide warm golden tones, suitable for bright terraces and balconies. Cumaru deck tiles feature rich reddish-brown grain, combining strength with character. These tropical hardwoods are naturally dense and can withstand exposure to the elements common in Saint Paul.
Deck tiles are available in two common sizes: 12 x 12 inches and 24 x 24 inches. The 12 x 12 inch format is compact, suitable for smaller areas or layouts with more edges and transitions. The larger 24 x 24 inch format is often preferred for more expansive terraces and open surfaces, resulting in fewer tile seams. Consider how the tile size will impact the visual scale of your balcony or rooftop and the number of cuts required for your specific layout. (S1)

Worked Example: Balcony Deck Tile Planning
Let's consider a hypothetical balcony project in Saint Paul. Your balcony measures 8 feet wide by 10 feet long (80 square feet).
You decide to use 24 x 24 inch Garapa deck tiles. Each tile covers 4 square feet. To calculate the number of tiles needed: 80 sq ft / 4 sq ft per tile = 20 tiles. However, this is just the area coverage. For a precise fit, you must consider the layout.
The balcony width is 8 feet (96 inches). With 24-inch tiles, this means 96 / 24 = 4 tiles across perfectly. The length is 10 feet (120 inches), so 120 / 24 = 5 tiles long perfectly. This ideal scenario means you would need 4 x 5 = 20 tiles, with no cuts if the dimensions are exact and edges are finished without overhang.
Always verify the exact thickness of your chosen deck tile and the height range of your selected pedestal system.
Remember to account for a small gap around the perimeter for expansion and drainage, as well as any edge finishing pieces. It's often prudent to order a few extra tiles to account for cuts, potential damage during installation, or future repairs. For this example, ordering 22-24 tiles (10-20% overage) would be a reasonable approach.
Before you order
- Confirm structural load capacity of balcony/rooftop with a professional.
- Measure all door thresholds and vertical clearances accurately.
- Identify existing drainage points and plan for unobstructed water flow.
- Select deck tile species (Ipe, Garapa, Cumaru) based on aesthetics and performance.
- Choose appropriate deck tile size (12x12 or 24x24) for your layout.
- Determine the assembly method (e.g., direct lay, pedestal system) compatible with clearances and drainage.
- Obtain any necessary building permits or approvals from building management.
- Account for perimeter gaps and edge finishing in your layout plan.
- Calculate required tile quantity, including a reasonable overage for cuts and spares.
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 special permission to install deck tiles on my Saint Paul balcony or rooftop?
Yes, for most multi-unit buildings or commercial properties in Saint Paul, you will likely need approval from your building's management, homeowners' association, or condo board before installing deck tiles. This is particularly true for rooftops, where structural integrity and waterproofing are critical. Always consult with them first to understand their specific requirements, including potential permits or engineering reviews.
Can deck tiles be installed directly on a waterproof membrane?
It depends on the specific membrane and manufacturer's recommendations. While some deck tile systems can be laid directly, it's often advisable to use a pedestal system, especially on rooftops. Pedestals lift the tiles off the membrane, protecting it from abrasion, allowing for better drainage, and creating an air gap for ventilation. This also helps in leveling the surface if the membrane is sloped for drainage. Always verify compatibility with your membrane manufacturer.
How do I ensure my deck tiles don't shift or blow away in strong winds?
For elevated installations, especially on rooftops or exposed balconies in Saint Paul, wind uplift can be a concern. Hardwood deck tiles are generally heavy, which helps with stability. However, for added security, especially with pedestal systems, consider options like perimeter fastening, using heavier pedestals, or incorporating a system that allows tiles to be mechanically secured to the pedestals. Consult with your installer or system manufacturer for recommendations specific to your project's exposure and local wind load requirements.
