Mackintosh Corporation supports the Quezon City Green Roof Ordinance. Quezon City Ordinance 1940 requires all New Building and Housing constructions to plant and maintain vegetation on their Rooftops. In terms of this Ordinance should a roof deck (or roof) be converted to a roof garden and maintained as such this area may be deducted from property taxes for 10 years.
Green roofs are the way of the future in that it is not only environmental friendly, an essential tool in combating the effects of global warming and climate change, combats the “heat island effect” but also translates into real energy savings.
The Benefits of a Green Roof include increased energy efficiency (from cooling in the summer and added insulation in the
winter), longer roof membrane life span, sound insulation and the ability to turn wasted roof space into various types of amenity space for building occupants. Green roofs filter particulate matter from the air, retain and cleanse storm water and provide new opportunities for biodiversity preservation and habitat creation. They generate aesthetic benefits and help to reduce the ‘urban heat island effect’ – the overheating of cities in the summer which contributes to air pollution and increased energy consumption.
Mackintosh Corporation has the products in Sika Sarnafil and K10 GRS 2000 to effectively waterproof green roofs. Sika Sarnafil is a hot air weldable PVC membrane and K10 GRS 2000 is a root resistant liquid applied polyurethane with Singapore Green Label Certification.
“Climate Change is the most serious and most pervasive threat facing humanity today. The Intergovernmental Panel on Climate 
Change (IPCC), the highest scientific body responsible for evaluating the risk of climate change, affirmed in its Fourth Assessment Report that the “warming of the earth’s climate system is unequivocal” and that this warming is attributed to the dramatic rise in human-induced greenhouse gas emissions since the mid 20th-century. The Philippines, an archipelagic nation of over 90 million people, now faces threats from more intense tropical cyclones, drastic changes in rainfall patterns, sea level rise, and increasing temperatures. All these factors contribute to serious impacts on our natural ecosystems—on our river basins, coastal and marine systems, and their biodiversity—then cascading to impacts on our food security, water resources, human health, public infrastructure, energy, and human settlements.” Climate Change Commission in its National Framework Strategy on Climate Change 2010-2022
No other architectural style provides such a wide range of positive effects for buildings, inhabitants, and the environment. Thus, Green Roofs meet one of the essential conditions of sustainable development, the reconciliation between economy and ecology.
Using green roofs as the site for an urban agriculture project can reduce a community’s urban footprint through the creation of a local food system.
