Artificial Turf for Rooftops and Patios: A Complete Guide

Not every turf installation goes on dirt. Some of our most impressive projects have been on concrete patios, rooftop decks, and other hard surfaces where traditional landscaping isn’t an option. If you’ve got a patio that feels like a concrete desert or a rooftop with unrealized potential, turf can completely transform the space.

Why Turf Works on Hard Surfaces

Concrete patios and rooftops are functional, but they’re not comfortable or inviting. They get scorching hot in Georgia summers, they’re hard on bare feet, and they look industrial. Turf installed over these surfaces provides a soft, comfortable walking surface that’s pleasant barefoot. It reduces surface temperature compared to bare concrete in direct sun, creates a green, inviting aesthetic that feels like an outdoor living room, and adds cushion for kids playing, pets lounging, or adults relaxing.

The transformation is dramatic. We’ve turned sterile concrete patios into spaces where families actually want to spend time, and rooftop decks into urban oases that feel miles away from the city below.

Installation on Concrete Patios

Installing turf on an existing concrete patio is one of our most straightforward projects—if the concrete is in good condition. Here’s the process:

Step 1: Assess the Concrete

The concrete needs to be structurally sound with no major heaving, cracking, or settling. Minor surface cracks are fine—they’ll be hidden under the turf. The critical factor is drainage: the patio must have adequate slope (at least 1% grade) to move water off the surface, because water will drain through the turf and hit the concrete below.

Step 2: Clean and Prep

We pressure wash the concrete to remove dirt, mildew, and debris. Any low spots that could pool water get filled with self-leveling compound. The surface needs to be clean and reasonably smooth for proper adhesion.

Step 3: Install Drainage Mat

This is the key layer. A specialized drainage mat (typically a dimpled polypropylene sheet) goes over the concrete. The dimples create channels that allow water to flow laterally across the concrete to the edges, where it drains off naturally. Without this layer, water gets trapped between the turf backing and the concrete, leading to mold, mildew, and odor.

Step 4: Lay and Secure the Turf

The turf is cut to fit, positioned, and secured using outdoor adhesive applied to the perimeter and seams. On concrete, we don’t use landscape spikes (there’s nothing to drive them into)—adhesive and weight do the job. For smaller areas, some installations use interlocking turf tiles instead of rolled turf for even simpler installation.

Installation on Rooftops

Rooftop installations are more complex because of structural and waterproofing considerations.

Weight Load

Artificial turf with infill weighs approximately 2-4 pounds per square foot—much lighter than soil and natural grass (which can weigh 20+ pounds per square foot when wet). Most rooftops that are designed for foot traffic can easily handle turf. However, we always recommend having a structural engineer verify the load capacity, especially for older buildings or large installations.

Waterproofing Protection

The existing roof membrane must not be compromised during installation. We never penetrate the roofing membrane with screws, nails, or stakes. Instead, turf is secured using perimeter weight bars, adhesive applied to designated attachment points, or ballasted edge systems. A protective layer goes between the roof membrane and the drainage mat to prevent any abrasion.

Wind Uplift

Rooftops experience higher wind loads than ground-level installations. The turf, infill, and drainage system need to be heavy enough to resist uplift. For high-rise rooftops, we may use heavier infill or additional perimeter anchoring to ensure the turf stays put during Georgia’s occasional severe thunderstorms.

Drainage Solutions for Hard Surfaces

Drainage is the most important consideration for any hard-surface turf installation. Options include drainage mats that channel water laterally to edges, perimeter drains that collect water around the turf border, connected drain systems that tie into existing roof or patio drains, and slight slope built into the sub-surface to direct water flow.

For patios with zero slope (completely flat), we can sometimes install a thin layer of self-leveling compound with built-in slope before the drainage mat goes down. This adds cost but ensures proper water management.

Best Turf Products for Hard Surfaces

Not all turf products work equally well on hard surfaces. For patio and rooftop installations, we recommend shorter pile heights (1.25-1.75 inches) which feel better underfoot on hard surfaces and don’t trap as much heat. Products with built-in drainage backing perform better than those relying solely on drainage holes. Softer fiber types like polyethylene provide more comfort when the underlying surface is concrete rather than a cushioned aggregate base.

Design Ideas

• Outdoor living room: Turf as the "floor" with outdoor furniture, string lights, and potted plants creating a cozy living space.
• Rooftop entertaining: Turf area for lounging next to a hardscape zone for dining, with a bar area and views of the city or mountains.
• Kids’ play surface: Turf over concrete creates a safer, softer play area. Add a play structure with proper fall zone coverage and you’ve got a backyard playground on a previously unused patio.
• Pet relief area: For condo and apartment dwellers, a turf patch on a balcony or patio gives dogs a familiar surface for bathroom breaks.
• Yoga and exercise: A turf section provides a comfortable, non-slip surface for outdoor workouts.

Cost Considerations

Hard-surface installations typically cost $10-$18 per square foot, compared to $8-$15 for ground installations. The premium covers the drainage mat system, adhesive instead of traditional anchoring, and the additional labor involved in working on elevated surfaces (especially rooftops where material has to be carried up).

For a typical 200-square-foot patio, expect to invest $2,000-$3,600. For a 500-square-foot rooftop, $5,000-$9,000. The investment transforms unusable or underused space into functional outdoor living area—which, in Georgia’s climate, is like adding another room to your home for 8-10 months of the year.
