Plano Roofing: Article About DIY Rooftop Garden
Rooftops are a great way to add visual interest to the home, create extra entertaining space and encourage the proliferation of different types of flora and fauna. While there are as many different varieties of rooftop gardens as there are rooftops, there is a basic formula that can be used to create a simple, do-it-yourself rooftop garden for a flat or sloped roof.
The first step is to ensure that the roof can support the weight of the garden. As a general rule of thumb, a rooftop garden can weigh up to 150 kg per square meter of roof space. A Plano roofing specialist can help homeowners maximize the size and scope of the garden without compromising the weight limitations of the roof.
Once the garden is planned, the first step is to lay down a pond liner over the space where the garden will go. This keeps roots, greenery and storm water from poking up through the finished garden. Tuck the liner into any leading around the roof to encourage storm water to run off. Trim away any excess edges, and repeat the process with a second pond liner.
Cover the second pond liner with two bags of gravel. Then, roll on a root membrane.

A root membrane is a substance that keeps dirt, mud and other debris from reaching the gravel. It can be purchased from the garden center of most home improvement stores.
Next, place a moisture blanket over the root membrane, leaving a 7-inch border on all sides. Cardboard or old bedsheets can be used as moisture. Sprinkle a thin layer of gravel over the top. Cover the 7-inch border with large gravel, pebbles or decorative stones. This encourages proper drainage and discourages plants from growing downward through the roof.
Sprinkle a bag of untreated wood chips over the moisture membrane to lock in extra moisture. Then, add a layer of compost substrate to feed the plants and top soil to enhance the compost. Stomp the soil down until it is solid and firm but not too tightly packed. At this point, paving slabs may be added if desired.
Finally, it's time to add the plants. Consult an almanac or local horticulture guide to determine appropriate plants based on geography and climate. Choose several different plant types, and install them in small patches, keeping in mind that the plants will spread over time. Water plants as necessary, and enjoy the garden frequently!.
