We will review green roofs not only from Eco-friendly perspective, but also from a roofer’s point of view, as it is the roofer that make green roof work. We’ll also discuss recent technological breakthroughs in green roofing industry, which simplify design, installation and greatly reduce costs.

Cost issues associated with Green Roofs:

Green roofs are expensive – no doubt about that. Main reason being the relative difficulty of building and maintaining a green roof, while making sure the water-proofing membrane is intact and performs for its specified life-period. Another reason is that all the components of a green roof (of which there are many) are expensive, and only a handful of suppliers offer them. Green Roof vegetation is also a concern a these plants must be able to survive in a limited amount of soil and if the drought hits, these plants might not survive. It may also be necessary to set up some kind of sprinkler system to maintain the required moisture level.

Technological (installation) issues associated with Green Roofs:

When all is set and done, a green roof will create a beautiful roof-top-garden and should significantly increase, if not double the life of your roofing membrane, as it protects the roof from sun and elements. Green roof will also make your building a lot cooler, as it absorbs most of solar heat.

Despite all these benefits and improvements, it is of the utmost importance to use the best available flat roofing membrane such as 80-mil IB Roof and to have a quality installation performed by a certified flat roofing installer. Just imagine that your new green roof is installed and some time later the roof begins to leak – now you have to disassemble the green roof: remove the vegetation and soil, moisture retainers and water-flow base, while the leak may not even be where you think it is. That is why from the installation perspective everything must be installed to the highest standard as well as all seams must be checked and double checked in order to ensure a leak-free roof functioning.

IB Roof and GreenRoofBlocks – the perfect combination for a Green Roof:

To make the installation and maintenance of green roof as simple and inexpensive as possible, we chose to combine our IB Pvc roofing products with a simple, modular approach of Green Roof Blocks. These green roof sections come in 2×2′ aluminum boxes with specially formulated light-weight soil. Green Roof Blocks offer a quick installation, ease of roof repair – if there is ever a need to do some roof maintenance, all you need to do is to simply lift up the sections where you suspect the leak may be. Green Roof block are also the most cost-effective green roof you can find. Vegetation can be planted and grown before the roof is installed or right on the roof-top.
