A Lawn on Your Roof

February 15, 2013 | Gardening, Lawn Care

Already common in Scandinavian and other European homes, grass rooftops are slowly gaining ground here in the States. Grass rooftops have long been celebrated for their energy-saving qualities but are gaining popularity today for the way they soften the harsh lines of urban landscapes.

Grass rooftops, sometimes called eco-roofs, have successfully been installed on commercial and residential structures alike, with the twin goals of minimizing bills and maximizing beauty.

Inspired? Check out the benefits of installing a lawn on your rooftop:

  • Absorbs heat and sound
  • Minimizes bills by insulating roof against swings in temperature
  • Helps manage stormwater
  • Extends the life of your roof: grass protects the roof membrane from sunlight, which breaks down the material over time
  • Can be much lighter than the same thickness of shingles
  • Produces oxygen and reduces carbon dioxide levels
  • Adds a serene beauty to the home

If seriously considering a grass rooftop, there are some complications to keep in mind, however:

  • They require specialized installation and maintenance (watering, cutting)
  • An additional drainage system must be in place before the grass is installed
  • The roof must be able to support the weight of the soil and grass (it is necessary to get a structural evaluation from an architect or engineer before proceeding)
  • Best on flat or slightly sloped rooftops
  • Some insects may invade your home


It is typical for homeowners to choose a variety of sod that only grows to a low height, such as our
Tifway 419 Bermuda grass, thus cutting out the need to mow.
