Deck Tiles for Rooftops and Balconies in Detroit, MI

Understanding Your Elevated Space: Balcony vs. Rooftop

While both balconies and rooftops are elevated, they often have different structural capacities, waterproofing systems, and access points. A balcony is typically an extension of a building floor, supported by cantilevers or columns, and often has a finished underside. Rooftops, especially those over living spaces, are primarily designed for weather protection and typically feature a membrane waterproofing system and a slope for drainage.

Before selecting deck tiles, identify if your project is on a true roof structure or a balcony. This distinction influences the type of support system needed for the deck tiles, the required clearance for door thresholds, and how drainage will be managed. For rooftops, verifying the existing roof membrane's condition and ensuring it can accommodate the tile system without compromising its integrity is crucial. Balconies might have less variability in their base, often being a concrete slab, but still require attention to drainage and height transitions.

Choosing the Right Deck Tile Material and Size

Lumber Plus offers deck tiles in various hardwood species, each with distinct characteristics. Ipe deck tiles are known for their deep chocolate tones, offering a classic hardwood appearance. Garapa deck tiles feature warm golden tones, suitable for brighter outdoor spaces. Cumaru deck tiles present a rich reddish-brown grain with notable strength.

Deck tiles are available in two primary sizes: 12 x 12 inches (1 square foot per tile) and 24 x 24 inches (4 square feet per tile). The 12 x 12 inch format is often chosen for smaller areas or layouts with more intricate edges and transitions, such as around columns or planters. The larger 24 x 24 inch format can be suitable for more open terraces or rooftops, potentially resulting in fewer tile seams across expansive surfaces.

The choice of material and size should align with your design aesthetic, the project's scale, and practical considerations like weight and handling during installation. Consider requesting samples to see how the natural color and grain appear in your project's light conditions.

Navigating Building Permissions and Structural Review in Detroit, MI

Any alteration to a rooftop or balcony in Detroit, MI, particularly those involving new structures or significant weight additions, may require building permits. It is essential to consult with the City of Detroit Buildings, Safety Engineering and Environmental Department to understand local regulations and permit requirements before beginning your project. This often includes submitting plans for structural review to ensure the existing building can support the added weight of the deck tiles, support system, and any furniture or planters.

For rooftop projects, the structural capacity of the roof is a critical factor. The combined weight of the deck tiles, the pedestals or sleepers, and any live loads (people, furniture, snow, etc.) must not exceed the roof's design load. Balconies also have weight limitations that must be respected. A qualified structural engineer can assess the existing structure and provide recommendations or certifications necessary for permitting. Neglecting this step can lead to safety hazards and code violations.

Addressing Drainage and Thresholds

Effective drainage is paramount for any elevated outdoor space. Deck tiles, especially when installed on a pedestal system, allow water to drain through the gaps between tiles to the underlying waterproof surface. This underlying surface must be sloped correctly towards drains or scuppers to prevent standing water.

For rooftops, ensure that the deck tile system does not obstruct existing roof drains or compromise the flow of water. Access to drains for maintenance and cleaning should be preserved. On balconies, check that water can flow freely off the edge or towards integrated drainage systems without pooling against the building facade or near door thresholds.

Door thresholds present another design challenge. The finished height of the deck tile surface must accommodate door swings and maintain sufficient clearance. Measure the existing threshold height carefully to determine the maximum allowable height for your deck tile system, including any pedestals or sleepers. In some cases, low-profile support systems may be necessary to achieve the desired finished height without impeding door operation.

Worked Example: Planning a 10' x 12' Balcony in Detroit

Consider a hypothetical 10-foot by 12-foot concrete balcony in Detroit, MI, where a homeowner wishes to install 24 x 24 inch Garapa deck tiles. The balcony has a door threshold that allows for a maximum finished tile height of 2 inches above the concrete slab. The slab slopes gently away from the building towards integrated scuppers.

First, calculate the area: 10 ft * 12 ft = 120 square feet. Each 24 x 24 inch tile covers 4 square feet. So, 120 sq ft / 4 sq ft/tile = 30 tiles. However, this is just area coverage. A precise layout sketch is needed to account for cuts and edge pieces. If we consider a straight grid, 10 feet is 5 tiles (120" / 24"), and 12 feet is 6 tiles (144" / 24"). This means 5 * 6 = 30 tiles with no cuts, assuming perfect alignment. Always add 5-10% for cuts and waste, so ordering 32-33 tiles would be prudent.

Next, address the height. Pedestals are adjustable, allowing for leveling and maintaining the necessary drainage slope. The pedestal system chosen must be compatible with the tile type and provide the required height adjustment.

This would involve a structural review, potentially by an engineer, to confirm the design load of the existing balcony.

Before you order

• Confirm if the project is a balcony or rooftop and understand its unique structural and waterproofing characteristics.
• Verify local building codes and permit requirements with the City of Detroit's relevant departments.
• Obtain a structural review by a qualified engineer for both rooftops and balconies to ensure load capacity.
• Measure existing door thresholds carefully to determine the maximum allowable finished height for deck tiles.
• Assess the existing drainage system and plan how the deck tile installation will maintain or enhance water flow.
• Select deck tile material (Ipe, Garapa, Cumaru) and size (12x12 or 24x24) based on aesthetic and practical needs.
• Choose a compatible support system (pedestals or sleepers) that addresses height, leveling, and drainage requirements.
• Create a detailed layout sketch to estimate tile quantities, including allowances for cuts and waste.
• Plan for access to roof drains or scuppers for future maintenance.

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.
