Green roofs, also known as living roofs, eco roofs, roof terraces or roof gardens, are a roof design of a building that is partly or entirely enclosed with vegetation and growing medium, therefore, the roof is planted over a waterproofing membrane and it has extra layers, for instance roof fence and drainage. He and Jim, (2010) states that green roof require the making of vegetated space on the top of artificial structures design. They can help to reduce the thermal properties of buildings to produce cooling energy conservation and increase social comforts. There are two main types of Green Roof-Intensive and Extensive.
Castleton and Davison, (2010) explains that intensive green roofs have a shallow substrate layer that tolerate deeper rooting plants, so that the trees and shrubs can remain alive. They are usually accessible and need regular maintenance such as extensive irrigation and fertilising. This type of roofs is generally thicker and can support a wider selection of plants and generally they are heavier systems, but therefore it has the highest demand on building structures. Fioretti and Palla, (2010) suggest that Intensive roofs are considered to be expensive to maintain and to build.
Nagase and Dunnett, (2010) debates that extensive roofs are not appropriate for plant growth, therefore it has inadequate water accessibility, extensive temperature variations, great exposure to wind and solar radiation that generates highly strained, and occasionally troubled environment. Due that reason, insignificant variety of plant types is generally used for extensive roofs. Sedum types are the most frequently used plant, Dunnett and Kingsbury, (2008) suggest that they are greatly adapted to dry environments. Extensive Green Roofs...

Biodiversity
An important feature of green roofs is their potential to provide habitation for urban wildlife, therefore many animal species such as rats and ants would benefit from green roofs. Coffman and Waites, (2008) explains that the urban development practices recognised as roof greening offers habitat for wild species within the towns and it also helps rise the home-grown natural diversity. However, roof greening is not a method restoration ecology, but it is method of reconciliation ecology, where entirely new habitation is formed for non-human species. In addition Green roofs certainly delivers some form of habitat, it is also possible that the properties of the roof could harm the wildlife diversity.
Every home has its own distinctive requirements, and roofing contractors offer many different services to help keep homes totally free from the elements, and to save owners on repair costs as a long-term solution. This can include repairs, insurance claims and roof inspections. A roof inspection can tackle issues, or perhaps be employed as a completely preventative measure for the peace of mind that the roof is working, and shielding the residence as designed.
Wood shingles are split pieces of wood used for roofing. What type of roofs are made of are very important to firefighting purposes because the can self-vent itself, and knowing which type of shingles and type the structure is, is going to decide if there is going to be ventilation operation. There are testing laboratories that rate wood shingles on a scale of A, B or C. A being the most fire resistant and C being the least. The test includes exposure, spread of flame, and resistance to burning brands or flying pieces of wood. Then some homes may have heavy clay tile roof instead of wood shingles. Or some structures could have a steel roof panel under the wood shingles. For example, La Grande Rural Fire District conducted a burn to learn operations for new and upcoming firefighters like myself, to see what it’s like to be in a structural fire. Getting towards the end, my duty was to make a ventilation cut on the D side of the structure. The type of roof was like a gable and valley roof. This roof was hard to make a thorough cut because there was a strong metal panel of roofing and then the wood shingles. Heavy clay tile roofs were popular in the 1920’s and 1930’s. There are reports of tile roofs collapsing from firefighters venting, to the roofs collapsing over them and having line of duty
The roof of your home is the first defensive aterial against many elements. The quality, shape and condition of your home's roof can directly effect on the value of your home and appearance. Now there are many choices available in the market ranging from traditional wood to eco friendly rubber. It is always recommended you to choose the roof which suits best to your home location, style, structure and climate. There are different roofing materials available which have pros as well as cons. The asphalt shingles roofs are very popular. The main pros of this roofing material are that it is economical and you can repair it easily. The other advantage is that this type of roofing material is available in different types of shapes, colors, and sizes. The asphalt
Tennessee Williams’ Cat on a Hot Tin Roof deals with various motifs and themes such as cats, masculinity, the crutch, alcohol, children, death, etc. It could easily be argued quotations including the phrase “a cat on a hot tin roof” represent the entirety of the play due to Williams’ repetitious use of the line, as well as of its use in the title. However, the plot of Cat on a Hot Tin Roof deals with tragedy being caused from miscommunication and lies, despite the exaggeration of cat-like women and the numerous mentions of cats. The quotation, “Wouldn’t it be funny if that was true?” unveils the sad disposition of the characters as they attempt to cover up the painful truth despite knowing “painful things caint always be avoided” (Williams,
Roof gardens – Taking advantage of every square inch of the building, making a previously useless area habitable
The term ‘green roof ‘ is defined as a rooftop garden which provides both environmental and economic benefits to the building. Green roof consists of soil and vegetation that are planted over a waterproof membrane material. There are two different types of green roofs which are extensive green roof and intensive green roof. An extensive green roof system has an overall depth of 3 to 5 inches and is used as a living machine with restricted access to the public except for maintenance purpose (Green Roof Technology). The weight of an extensive green roof is about 60kg to 150kg per square metre (International Green Roof Association, 2014). On the other hand, an intensive green roof system has an overall depth of 7 to 24 inches and is best suited for being used as a garden or park for the consumers (Green Roof Technology). The weight of an intensive green roof is about 180kg to 500kg per square metre (International Green Roof Association, 2014).
Have you ever experienced frequent commercial roofing issues, shingles falling apart or mildew building up in your business due to moisture and you can not figure out why? Every so often a business owner will purchase a house with an existing roofing system in place or plan on repairing a damaged roof, and will end up coming to the conclusion that there is no proper or non existent roofing ventilation in place for your roof. Just as we need crisp air for humid days, our roofs need proper ventilation for the highest performance. Warfeather in Coweta, Oklahoma has seen first hand how absolutely no roofing ventilation or erroneous ventilation can cause premature deterioration of the shingles and commercial roofing system
Urban landscape has caused habitat fragmentation to various habitats by reducing wildlife areas to tiny sections, or has wiped out animal habitats, cause animals to cross dangerous areas like roads and train tracks, and has cause pollution and minimal animal wildlife activity in the fragmented areas. Due to the human population growing, more houses, apartment buildings, office buildings, etc. Every time each house or other building is built, the habitat size is reduced, even destroying habitats and removing any necessitative resources for animals in that ecosystem. As well, since urban landscapes reduce the size of wildlife areas through human developments like roads, animals
A dream home is never complete without an attractive roof that matches its exterior and interior décor. Many homeowners like customized roofs as they offer a personal taste of shade or design. Residential roofing is an integral part of every home since it protects all the items inside and maintains the value of your home. However, roofing should be carried by professionals considering that correct roofing is a huge investment. The following is a close at considerations when installing or replacing your roof.
The roofing industry is evolving, understanding that more of their customers will eventually request recyclable roofing materials, and that green roofing companies are the way of the
Green roof are defined as roofs that support vegetation, covering either full or partial of live plant material. At present, cities are now considering extensive planting as a mean of improving of air quality. Green roof can also be a good material tool in the environment. Most of the time, people would be confused to identify the green roof with rooftop garden, although the benefit of green roof and rooftop garden are quite similar but there are significantly differences between the two. Green roof is always put up with layered system unlike rooftop garden that has characterized by built-in planting areas for food production and can occupy a small proportion of roofs, but in other places, they made green roof as there garden. Through vegetation
A green building (also referred to as sustainable building or green construction) is a structure that employs an approach that is responsible for the environment besides being efficient in regard to resources all through its life cycle: This is from selecting the site to designing it, constructing, operating, maintaining, renovating and demolishing it. To achieve this, the client, the engineers, the architects and the entire design team closely cooperate at all stages of a project (Yan and Paliniotis, 2006). Practicing Green Building complements and expands the conventional building design areas of comfort, durability, utility and economy.
These motives are behind the current world’s 50% urbanization rate. Among all countries, Canada heads the urbanization process with 80% of its total area (Snell par.7). The ever-increasing urbanization rate is characterized by human-related destructive activities, which lead to creation of urban centers by destroying inherent biodiversity. The rate is increasing each passing day. However, one thing to note is that destructive activities embody the causes of urban biodiversity wicked problem. The easy way of identification provides land conversion, climate change, consumerism, land fragmentation, and invasive species as the main causes of the wicked problem of urban biodiversity. These causes constitute every aspect of urban life. For instance, there is no way that people living in urban areas can do without proper infrastructures (such as houses, roads, and communication lines). All kinds of infrastructure need space, and, in creating it, there is clearance of all natural vegetation and conversion of land to other uses. The result is annihilation of nature and predisposition of climatic changes. The only easy approach to identify an appropriate solution to the wicked problem of urban biodiversity is to decrease the rate of urbanization by
A greenhouse is a structure with a glass or plastic roof and side walls that is used for the production of ornamentals and food crops and may be used seasonally or year round. The closed environment of a greenhouse has its own unique requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Significant inputs of heat and light may be required, particularly with winter production of warm-weather crops. (Douglas Cox, ,. 2010)
Green Building may be defined as the processes of planning, designing, constructing and operating a building, while taking into consideration: the quality of the indoor environment, selection of the materials used, the way of using energy and water and the effect of the building on the site.
