Deck Tiles for Rooftops and Balconies in Savannah, GA

Understanding Your Rooftop or Balcony Assembly

The foundation of any elevated deck tile project is the existing structure. Rooftops typically feature a waterproof membrane, insulation, and a sloped substrate designed to direct water to drains. Balconies, often concrete slabs, also have a slope for drainage and may have their own waterproofing.

Your deck tile system must respect these existing conditions. Deck tiles are a finish layer and do not provide structural support or waterproofing. Instead, they need an assembly that protects the underlying roof or balcony while allowing for efficient water drainage and airflow.

Common assembly methods include direct placement over a protective mat, or elevated systems using adjustable pedestals. Pedestal systems are particularly useful for creating a level surface over a sloped substrate, accommodating variations in height, and providing space for utilities or additional insulation. The choice depends on the specific site conditions, desired finished height, and local building codes.

Always confirm the load-bearing capacity of your rooftop or balcony structure before selecting any deck tile system. This often requires consulting with a structural engineer or the building management, especially for larger installations or if adding significant weight like large planters or hot tubs.

Navigating Building Permissions and Local Regulations

In Savannah, GA, as in many urban areas, projects on rooftops and balconies often require specific building permits or approvals from homeowners' associations (HOAs) or condominium boards. These regulations can cover aspects like material choices, total weight load, fire ratings, wind uplift resistance, and drainage plans.

Before purchasing materials or beginning any work, it is crucial to understand these requirements. Begin by contacting your building management, HOA, or the City of Savannah's planning department. They can provide guidance on necessary permits, required documentation, and any specific restrictions that apply to your property.

Be prepared to submit detailed plans, including material specifications, assembly methods, and a clear explanation of how the proposed deck tile system addresses drainage and structural integrity. Early communication can prevent costly delays or rework later in the project.

Critical Measurements: Door Thresholds and Drainage

Two of the most critical measurements for any elevated deck tile project are door thresholds and existing drainage points. The finished height of your deck tile surface must be below the bottom edge of any doors leading to the balcony or rooftop to prevent water intrusion and allow for proper door operation.

For drainage, it is essential that your deck tile system does not impede the flow of water to existing roof drains or scuppers. The design should allow water to freely pass beneath the tiles and reach the drainage points. This often means leaving a clear perimeter around drains or using specialized drain covers that integrate with the tile system.

When planning, measure the height from your existing substrate to the lowest point of your door threshold. This will determine the maximum allowable height of your deck tile assembly, including any pedestals or support mats. Also, meticulously map out the location of all drains and ensure your chosen tile size and layout can accommodate them without creating water pooling areas.

Choosing Your Deck Tile Material and Size

Lumber Plus offers a range of hardwood deck tiles suitable for elevated projects. Each species provides a distinct aesthetic and character:

Ipe deck tiles: Known for their deep chocolate tones and exceptional hardness, Ipe offers a classic, rich appearance. (Source: S1)

Garapa deck tiles: These tiles feature warm golden tones, ideal for creating bright and inviting outdoor spaces. (Source: S1)

Cumaru deck tiles: Cumaru provides a rich reddish-brown grain, combining strength with a distinctive tropical hardwood character. (Source: S1)

In terms of size, you can choose between 12 x 12 inch and 24 x 24 inch formats. The 12 x 12 inch tiles are a compact square format, often suitable for smaller areas or layouts that require more cuts and transitions. The 24 x 24 inch tiles offer a larger square format, which can be efficient for open surfaces with fewer tile seams, potentially reducing installation time. (Source: S1)

Consider how the tile size will interact with your overall layout, especially around obstacles, drains, and edges. Larger tiles might mean fewer cuts but could be challenging in very confined or irregular spaces. Smaller tiles offer more flexibility for intricate patterns but increase the number of seams.

Worked Example: Balcony Deck Tile Planning

Consider a hypothetical balcony project in Savannah, GA. The balcony measures 10 feet by 6 feet, and has a single door leading to it. The existing concrete slab slopes gently towards a perimeter drain. The critical door threshold is 3 inches above the concrete slab.

1. A 24 x 24 inch Garapa deck tile is approximately 1.25 inches thick. An adjustable pedestal system that can achieve this low height is necessary.

2. Calculate Tile Quantity: The balcony area is 10 ft x 6 ft = 60 square feet. Each 24 x 24 inch tile covers 4 square feet. Area-equivalent coverage is 60 sq ft / 4 sq ft/tile = 15 tiles. However, due to cuts, we need to plan for full tiles.

Layout: Along the 10-foot side (120 inches), we need 120 inches / 24 inches/tile = 5 tiles. Along the 6-foot side (72 inches), we need 72 inches / 24 inches/tile = 3 tiles. This is a perfect 5x3 grid, requiring 15 full tiles with no cuts. This is an ideal scenario. If dimensions were not exact multiples, additional tiles for cuts and waste would be needed.

3. Drainage Plan: The existing perimeter drain is critical. The pedestal system will elevate the tiles, allowing water to flow freely underneath to the drain. The pedestal spacing will be planned to maintain a slight gap at the perimeter to ensure water can exit.

4. Building Approval: Before ordering, the building management would be consulted regarding material specifications, proposed assembly, and weight load. Documentation on the Garapa deck tiles and the chosen pedestal system would be prepared for submission.

Before you order

• Confirm the existing structure's load-bearing capacity with a structural engineer or building management.
• Obtain necessary permits or approvals from your HOA, condominium board, or the City of Savannah planning department.
• Measure all door thresholds accurately to determine the maximum allowable height for your deck tile assembly.
• Map out all existing roof drains, scuppers, and other penetrations to ensure unobstructed water flow.
• Select a deck tile material (Ipe, Garapa, Cumaru) and size (12x12 or 24x24) that aligns with your aesthetic and functional needs.
• Choose an appropriate assembly system (e.g., pedestals, protective mats) that accommodates your site's slope and desired finished height.
• Plan your tile layout to minimize waste and ensure proper integration with drains and edges.
• Consider the long-term maintenance requirements for your chosen hardwood species.
• Request a material quote with exact dimensions, chosen profile, and your ZIP code to confirm availability and service options.

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.
