Roof top keys: wind water and weight

Wind

Wind speed doubles every ten stories, small containers should be avoided, midsized containers need to be weighted down with gravel drainage at the bottom of the container

Windy conditions dry out soil and pull moisture from plants

Select plants for wind tolerance, or install a wind block so plants won’t be harmed by strong winds

Trees and shrubs need to be closely monitored and pruned yearly to prevent any risk of falling branches

Drains and gutters need to be kept clear of plant material

Water

Make sure you have a way to water your plants, wind and the urban heat island effect and wind dry out rooftop plants quickly, depending on rain is often a risk unless you are collecting rainwater utilizing rainwater storage

Sub irrigated planters are useful but water chambers will have to be filled frequently

Irrigation systems on a timer are highly recommended

Drought tolerant plants are good for roofs you will be unable to water

Plants native to your area will be more likely to be able to live off rainwater, however, climate change is changing water conditions quickly

Plants without a watering system often require watering multiple times a day

Weight

If your will be growing many very large containers, or installing a green roof, consult with a structural engineer, most new building s are fine to carry the weight of plants, but older roofs often have weaker areas, different parts of the roof will be able to hold different amounts of weight

Additional considerations

Access

Getting on the roof: how you’re going to get your plants on the roof should be considered before planting the garden

Soil

Dirt gets very heavy when wet, this shouldn’t be an issue with container gardening a mix of compost and potting soil is a good start

Green roofs utilize specially formulated lightweight soil mixes that are often a mixture of compost and recycled material

Safty

In addition to the risk of plants flying off the roof in high wind, you could slip and fall off your roof, be safe!

Build a fence. This will stop you or your gear from falling and be a great wind block for your plants, most cities will want you to get a permit for your fence

Avoid leaving loose tools on the roof, as needed, tie items down
