On Roof-Gardens.com while caring your roof garden the first and the main concern is the load on the rooftop. Roofs that weren't constructed with gardening in mind must be checked for stability and leaks and then treated gently to avoid damaging the roof membrane. Once a roof is properly planted, the membrane can actually last longer than if it were left bare. The reason for this is that the membrane is insulated from damage. It is also insulated from heat loss and heat gain, making the building underneath easier to heat and cool.

Regardless of how strong your roof is, it's a good idea to use materials that don't weigh very much. Soil can be weighed per cubic foot. Most garden soils weigh approximately 160 to 170 pounds per cubic foot. If you mix 70% organic matter with 30% pumice, you can get the weight down to 60 pounds per cubic foot, and end up with a very light, well-drained mix. The depth of the soil and the soil used should also be kept at a minimum while ensuring plant health. This roof-full of perennial grass grows in only 12 inches of growing medium, using the above recipe for soil.

Some Tips to Keep in Mind
Though you may be ready to start planting soon, there are some little things to remember about your rooftop garden before you begin on Roof-Gardens.com:

First, you must have tough plants. On the roof these plants get the brunt of all the weather, year-round, so even with proper maintenance, the tougher the plant, the more productive the roof garden.

Second, make sure you have a flat or gently sloped roof. Otherwise there will be problems, not only with the plants themselves but with rainwater run-off as well.

Third, make sure everything is water tight and that your roof can handle the weight. Some roof gardens just use planters, and are therefore light. But if you're thinking of a more extensive project with pavers and stone, then make sure your roof is suitable for the installation.
