Finding The Ideal Vegetative Roof Here are factors to consider when specifying planted-roof systems.

The functional design of a rooftop makes a difference not only in the sort of materials used to construct the space, but in the types of plants installed. For example, will a patio, garden, or other usable space be incorporated? V egetative roofs are not a new concept, but it is new to many architects and designers who are approaching their first planted-roofing project. These green roofs are progressively catching on with building owners, as they offer a variety of benefits. Here are several reasons to pursue a vegetative roof.

MANDATED/EXTERNAL REASONS Various cities, such as Toronto and San Francisco, require or heavily incentivize vegetative roofs to deal with larger problems affecting the area, such as excessive stormwater runoff or urban heat-island effects. • Stormwater runoff is a major issue in municipalities where aging sewer systems can be overwhelmed and chemicals/waste can end up in waterways. Some sewer districts tax stormwater runoff as a result, and cities sometimes require new buildings to have water-retaining roofs to mitigate the problem. Vegetative roofing not only slows the rate of runoff during storms but can remove as much as 95% of heavy metals in rainwater. • Urban heat islands, where cities become especially hot when sunlight is absorbed into hard, dark surfaces, are another long-standing problem. Planted roofs alleviate this by absorbing sunlight instead of reflecting is as happens with nonporous surfaces. Vegetative roofs typically emit a temperature of only 95 F on a 90 F day. A traditional roof might exceed 160 F. • Green roofs can also help combat CO 2 and smog levels, actively converting CO 2 to O 2 to improve air quality.

BUILDING-SPECIFIC REASONS In other cases, a building owner might choose a green roof because of the benefits such a system grants to the owner. • A vegetative roof can help save energy by absorbing sunlight that

would otherwise raise the temperature in the building and tax the HVAC system, which is part of why its inclusion in a design can contribute points toward LEED credentials. • If a building has solar panels on the roof, green roofing can help the panels perform more efficiently. • Vegetative rooftops also protect the roofing membrane from UV radiation, heat aging, extreme temperature fluctuation, and physical damage. • Planted roofs simply look good, making them attractive in situations where the rooftop is visible to occupants or is an occupied space featuring useful overburden, such as pavers, flanked by plant life.

ASK CORRECT QUESTIONS There are a number of factors to consider when determining the proper design and construction of a planted roof. The following questions offer information to aid in the selection of a vegetative-roofing solution for a variety of needs.

What is the intended use of a vegetative rooftop?

Is the rooftop going to be a generally unoccupied space, chiefly designed to absorb rain and solar rays, or will it have visitors? Will a patio, garden, or other usable space be incorporated?

The functional design of the rooftop makes a difference in the materials used to construct the space and in the types of plants installed.

Work with a landscape architect to determine which plants are best, based on the desired use, climate, and how much time and resources can be dedicated to upkeep. Then, select the correct type of planted-roofing system to meet the requirements of those plants and the needs of the mixed-use design.

What value is to be received from the planted roof?

If you simply want the rooftop to look attractive, that is one thing. But if you want to derive more utility from the roof design (for instance, carbon dioxide/ greenhouse-gas management or stormwater management), that can affect vegetation choice and construction decisions.

Using a green roof for stormwater management is partially influenced not only by the ability of plants to soak up water through their roots, but also by structural factors below the soil layer of a planted rooftop.

Is storage space needed that allows water to collect below the soil level, minimizing the amount flowing off the roof during heavy rains? The construction of the drainage layer and choice of moisture-retention mats will depend on the answer to this question.

Based on the performance expected from the roof, is a traditional vegetative-roof construction or a traybased system needed?

Traditional vegetative roofs have various layers installed as part of their design, and the composition of those layers depends on the performance one is seeking, the weight-carrying capability of the roof, and other factors. Traditional vegetative-roofing constructions typically include: • Growing medium with custom soil depth on top with plants embedded

• A drainage layer with water-retention mats underneath to let plants absorb the needed amount of water • An insulation layer under the drainage layer to insulate the building against the elements • A root barrier designed to prevent penetration of roots into the waterproofing membrane • A waterproofing-membrane system to protect the building.

Tray systems can be used for smaller, multifunction spaces where water retention is less of a priority and vegetation is installed around patios, pavers, or designated garden areas. These reportedly easy-toinstall systems, such as the Sopranature modular tray system from Soprema Inc., Wadsworth, OH, are all-in-one systems that include a drainage layer, filter fabric, and pre-installed vegetation. They offer

How extensive/intensive a green- roof system is planned?

If a tray-based system is chosen, there are fewer decisions to make. A contractor simply installs what was purchased. If the roof is a traditional approach with a built-in-place system, the consideration process is more complex. What type of system will be created? • An extensive system is designed for projects requiring lightweight vegetative roofing. This typically includes sedum, herbs, or other low-maintenance plants that may not require an irrigation system and are installed more for utility than aesthetics. • A semi-intensive system allows more plant diversity, including small shrubs, grasses, and flowers. This design means more maintenance and irrigation is needed than an extensive system but provides better stormwater retention. • An intensive system requires the most maintenance and irrigation, but allows the creation of on-structure landscapes with deep soil profiles that can sustain large shrubs and small trees. These systems are often used to facilitate rooftop vegetable gardens or park-like spaces for multifamily residential buildings. This sort of system can retain the largest quantity of stormwater.

What is the real cost of the project?

Material choice is one factor infl uencing vegetative-roofi ng costs, based on the intensity of the project and which material options are chosen for each layer. Maintenance is another consideration, as certain plants require more care than others, especially when diverse, intensive plantscapes are designed.

Also consider what government incentives and tax abatements may be available. These can vary from city to city and state to state, and there could also be federal incentives for implementing green-roofing options. One can begin by reviewing some of the current offers listed at the following link to get an idea of how net costs of implementing a planted rooftop may be lower than anticipated.
