A flat roof is a roof which is almost level in contrast to the many types of sloped roofs . The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof . Flat roofs, or "low-slope" roofs, are also commonly found on commercial buildings throughout the world. The U.S.-based National Roofing Contractors Association defines a low-slope roof as having a slope of 3 in 12 (1:4) or less.
105-601: Bulimba Memorial Park is a heritage-listed park at 129 Oxford Street, Bulimba, Queensland , Australia. It was built from 1919 to 1980s. It is also known as Bulimba Soldiers & Sailors Memorial Park and Jamieson Park. It was added to the Queensland Heritage Register on 21 October 1992. Part of Bulimba Memorial Park may have been established by the Balmoral Shire Council as early as c. 1904 , as Jamieson Park. Following
210-587: A greenbelt . In some countries, especially the United Kingdom, country parks are areas designated for recreation, and managed by local authorities . They are often located near urban populations, but they provide recreational facilities typical of the countryside rather than the town. In 2021, following the 2020 Nagorno-Karabakh war , a Military Trophy Park was opened in Azerbaijan 's capital Baku , showcasing seized military equipment, as well as
315-517: A mixed-use path that is dominated by fast-moving cyclists or horses. Different landscaping and infrastructure may even affect children's rates of park usage according to gender. Redesigns of two parks in Vienna suggested that the creation of multiple semi-enclosed play areas in a park could encourage equal use by boys and girls. Parks are part of the urban infrastructure: for physical activity, for families and communities to gather and socialize, or for
420-500: A park ranger . Large parks may have areas for canoeing and hiking in the warmer months and, in some northern hemisphere countries, cross-country skiing and snowshoeing in colder months. There are also amusement parks that have live shows, fairground rides, refreshments, and games of chance or skill. English deer parks were used by the aristocracy in medieval times for game hunting. They had walls or thick hedges around them to keep game animals (e.g., stags) in and people out. It

Ministry of Foreign Affairs of Azerbaijan stated that such museums are a widely accepted international practice, and the country has a right to commemorate its victory through parades, parks, museums and other means. Azerbaijani authorities claimed that the helmets were left behind by retreating Armenian soldiers. When Azerbaijani historian Altay Goyushov, one of

The place demonstrates rare, uncommon or endangered aspects of Queensland's cultural heritage. The place is important as a Brisbane open space which, unusually, is available for both organised and informal recreational use. The place
735-586: A beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue grills. The largest parks can be vast natural areas of hundreds of thousands of square kilometers (or square miles), with abundant wildlife and natural features such as mountains and rivers. In many large parks, camping in tents is allowed with a permit. Many natural parks are protected by law, and users may have to follow restrictions (e.g. rules against open fires or bringing in glass bottles). Large national and sub-national parks are typically overseen by
840-411: A brick and glass, L-shaped structure. Near the 1923 grandstand are brick public toilets and a concrete block canteen, both with flat roofs . Bulimba Memorial Park was listed on the Queensland Heritage Register on 21 October 1992 having satisfied the following criteria. The place is important in demonstrating the evolution or pattern of Queensland's history. Bulimba Memorial Park is significant as
945-432: A building where it can be seen. Thus, it is not easy to find the source of the leak in order to repair it. Once underlying roof decking is soaked, it often sags, creating more room for water to accumulate and further worsening the problem. Another common reason for failure of flat roofs is lack of drain maintenance where gravel, leaves and debris block water outlets (be they spigots, drains, downpipes or gutters). This causes
1050-472: A canteen. During the 1980s the Brisbane City Council found that not all the subdivisions which comprised the park were Council owned. These were officially acquired, including the unformed James Street, and by 1990 the park contained over 4.6 hectares (11 acres). The park has been a venue for local cricket, rugby, soccer and other recreational uses since early this century. It is adjacent to
1155-550: A crack or puncture in the waterproofing membrane can quite readily lead to leaks. Flat roofs can fail, for example; when subsequent work is carried out on the roof, when new through-roof service pipes/cables are installed or when plant such as air conditioning units are installed. A good roofer should be called to make sure the roof is left properly watertight before it is left. In trafficked areas, proper advisory/warning signs should be put up and walkways of rubber matting, wooden or plastic duck-boarding etc. should be installed to protect
SECTION 10
#17327935146881260-449: A decorative and durable roof covering. Green roofs have been made by depositing topsoil or other growth media on flat roofs and seeding them (or allowing them to self-seed as nature takes its course). Maintenance in the form of simple visible inspection and removal of larger rooting plants allows these roofs to be successful in that they provide an excellent covering and UV light barrier for the roof waterproofing membrane. With some systems,
1365-427: A deeper profile roof sheet (usually 40mm deep or greater). This gives the roof sheet very high water carrying capacity and allows the roof sheets to be more than 100 metres long in some cases. The pitch of this type of roof is usually between 1 and 3 degrees depending upon sheet length. Any sheet of material used to cover a flat or low-pitched roof is usually known as a membrane and the primary purpose of these membranes
1470-514: A difference. Regular park maintenance, as well as programming and community involvement, can also contribute to a feeling of safety. While Crime prevention through environmental design (CPTED) has been widely used in facility design, the use of CPTED in parks has not been. Iqbal and Ceccato performed a study in Stockholm, Sweden to determine if it would be useful to apply to parks. Their study indicated that while CPTED could be useful, due to
1575-576: A faster installation. The addition of these tapes has reduced labor by as much as 75%. It is a low-cost membrane, but when properly applied in appropriate places, its warranted life-span has reached 30 years and its expected lifespan has reached 50 years. There are three installation methods: ballasted, mechanically attached, and fully adhered. Ballasted roofs are held in place by large round stones or slabs. Mechanically attached roof membranes are held in place with nails and are suitable in some applications where wind velocities are not usually high. A drawback
1680-465: A half-mile of a park indicated that in addition to safety park facilities also played a significant role in park use and that increasing facilities instead of creating an image of a safe park would increase use of the park. There are a number of features that contribute to whether a park feels safe. Elements in the physical design of a park, such as an open and welcoming entry, good visibility (sight lines), and appropriate lighting and signage can all make
1785-406: A hot liquid, heated in a kettle. A flooded coat of bitumen is applied over the felts and gravel is embedded in the hot bitumen. A main reason for failure of these traditional roofs is ignorance or lack of maintenance. The gravel coating protects the tar underneath from breaking down under UV rays from the sun. The gravel can shift from wind, heavy rainfall, or people walking on the roof. This exposes
1890-452: A lack of standards allowed a manufacturer to produce the product with insufficient APP, requisite to enhancing the system aging characteristics. A bitumen is a term applied to both coal tar pitch and asphalt products. Modified bitumens were developed in Europe in the 1970s when Europeans became concerned with the lower performance standards of roofing asphalt. Modifiers were added to replace
1995-509: A plastic or rubber ingredient and combined with a reinforcement. The final modified bitumen sheet goods are typically installed by heating the underside of the roll with a torch, presenting a significant fire hazard. For this reason, the technique was outlawed in some municipalities when buildings caught fire, some burning to the ground. This problem was alleviated by strict specifications requiring installation training and certification as well as on-site supervision. Another problem developed when
2100-446: A portion of the park's area eliminates or reduces the burden of managing active recreation facilities and developed infrastructure. Passive recreation amenities require routine upkeep and maintenance to prevent degradation of the environment. The general principle of how parks and greenspaces assist in the conservation of biodiversity is by creating natural environments for animals in urban areas. Biological diversity, or biodiversity ,
2205-464: A pressure head of water (the deeper the water, the greater the pressure) which can force more water into the smallest hole or crack. In colder climates, puddling water can freeze, breaking up the roof surface as the ice expands. It is therefore important to maintain your flat roof to avoid excessive repair. An important consideration in tarred flat roof quality is knowing that the common term ' tar ' applies to rather different products: tar or pitch (which

By buffering rainfall, such as by fitting green roofs, floods can be reduced or avoided:
2415-428: A sheet good, cut in manageable lengths for handling. SBS is used as a modifier for enhancing substandard asphalt and provides a degree of flexibility much like rubber. It also is applied to a myriad of carriers and produced as a sheet-good in rolls that can be easily handled. Styrene ethylene butadiene styrene (SEBS) is a formulation increasing flexibility of the sheet and longevity. Styrene-isoprene-styrene (SIS)
2520-488: A simple respite. Research reveals that people who exercise outdoors in green-space derive greater mental health benefits. Providing activities for all ages, abilities and income levels is important for the physical and mental well-being of the public. Parks can also benefit pollinators , and some parks (such as Saltdean Oval in East Sussex ) have been redesigned to accommodate them better. Some organizations, such as
2625-409: A specially made soakaway. Gutters on larger roofs usually lead water into the rainwater drainage system of any built up area. Occasionally, however, flat roofs are designed to collect water in a pool, usually for aesthetic purposes, or for rainwater buffering. Traditionally most flat roofs in the western world make use of felt paper applied over roof decking to keep a building watertight. The felt paper
2730-416: Is a growing concern. UV-rays oxidize the surface of the asphalt and produce a chalk-like residue. As plasticizers leach out of the asphalt, asphalt built-up roofs become brittle. Cracking and alligatoring inevitably follows, allowing water to penetrate the system causing blisters, cracks and leaks. Compared to other systems, installation of asphalt roofs is energy-intensive (hot processes typically use LP gas as
2835-473: Is a reserve of land, usually, but not always declared and owned by a national government , protected from most human development and pollution. Although this may be so, it is not likely that the government of a specific area owns it, rather the community itself. National parks are a protected area of International Union for Conservation of Nature Category II . This implies that they are wilderness areas, but unlike pure nature reserves, they are established with

The ground floor is constructed of concrete bricks while the first floor is weatherboard, and there is an extensive timber deck at first floor level. The Girl Guides' Hall is a two- storeyed weatherboard structure with a gable roof of corrugated iron. The senior citizens' club, at the corner of Stuart and Barramul Streets, is
3045-879: Is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments , fountains or playground structures. Many parks have fields for playing sports such as baseball and football , and paved areas for games such as basketball . Many parks have trails for walking , biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise
3150-441: Is an area of open space provided for recreational use, usually owned and maintained by a local government. Parks commonly resemble savannas or open woodlands , the types of landscape that human beings find most relaxing. Grass is typically kept short to discourage insect pests and to allow for the enjoyment of picnics and sporting activities. Trees are chosen for their beauty and to provide shade . Some early parks include

Type III, is considered to be "steep" asphalt but is limited to slopes up to 2 in 12 (1:6), and Type IV is "special steep". The drawback is, the longer it is processed, the shorter the life. Dead-level roofs where Type I asphalt is used as the flood and gravel adhesive perform nearly as well as coal tar. Asphalt roofs are also sustainable by restoring

Some of these products appear to have been interchanged in their use and are sometimes used inappropriately, as each has different characteristics, for example whether or not the product can soak into wood, its anti-fungal properties and its reaction to exposure to sun, weather, and varying temperatures. Modern flat roofs can use single large factory-made sheets such as EPDM synthetic rubber, polyvinyl chloride (PVC), thermoplastic polyolefin (TPO) etc. Although usually of excellent quality, one-piece membranes are called single plies and are used today on many large commercial buildings. Modified bitumen membranes which are widely available in one-meter widths are bonded together in either hot or cold seaming processes during

A park primarily intended for adults may feature walking paths and decorative landscaping. Specific features, such as riding trails, may be included to support specific activities. The design of a park may determine who is willing to use it. Walkers might feel unsafe on
3990-413: Is manufactured from oil as the intended purpose, and this is limited to high-quality asphalt produced for longer lasting asphalt built-up roofs (BUR). Asphalt ages through photo-oxidation accelerated by heat. As it ages, the asphalts melt point rises and there is a loss of plasticizers. As mass is lost, the asphalt shrinks and forms a surface similar to alligator skin. Asphalt breaks down slowly in water, and
4095-544: Is not readily available. In areas where the roof could become saturated by rain and leak, or where water soaked into the brickwork could freeze to ice and thus lead to 'blowing' (breaking up of the mortar/brickwork/concrete by the expansion of ice as it forms) these roofs are not suitable. Flat roofs are characteristic of the Egyptian, Persian, and Arabian styles of architecture. Around the world, many modern commercial buildings have flat roofs. The roofs are usually clad with

Water from some flat roofs such as on garden sheds sometimes flows freely off the edge of a roof, though gutter systems are of advantage in keeping both walls and foundations dry. Gutters on smaller roofs often lead water directly onto the ground, or better, into

7980-405: The more exposure the more rapid the degradation. Asphalt also dissolves readily when exposed to oils and some solvents. There are four types of roofing asphalt. Each type is created by heating and blowing with oxygen. The longer the process the higher the melt-point of the asphalt. Therefore, Type I asphalt has characteristics closest to coal tar and can only be used on dead level surfaces. Type II,
8085-399: The most common solution is removing and replacing the damaged area. If the problem is detected early enough, the insulation may be saved by repairing the leak, but if it has progressed to creating a sunken area, it may be too late. One problem with maintaining flat roofs is that if water does penetrate the barrier covering, it can travel a long way before causing visible damage or leaking into
8190-640: The nature of a park, increasing the look of safety can also have unintended consequences on the aesthetics of the park. Creating secure areas with bars and locks lowers the beauty of the park, as well as the nature of who is in charge of observing the public space and the feeling of being observed. Parks can be divided into active and passive recreation areas. Active recreation is that which has an urban character and requires intensive development. It often involves cooperative or team activity, including playgrounds , ball fields, swimming pools, gymnasiums, and skateparks . Active recreation such as team sports, due to
8295-586: The need to provide substantial space to congregate, typically involves intensive management, maintenance, and high costs. Passive recreation, also called "low-intensity recreation" is that which emphasizes the open-space aspect of a park and allows for the preservation of natural habitat. It usually involves a low level of development, such as rustic picnic areas, benches, and trails. Many smaller neighborhood parks are receiving increased attention and valuation as significant community assets and places of refuge in heavily populated urban areas. Neighborhood groups around
8400-405: The older ones having a larder variety of breeds and greenery. Vegetation in parks can indirectly reduce air temperature and directly reduce levels of carbon dioxide by storing it as a biomass and due to the trees’ ability to absorb over 95% of ultraviolet radiation the aid in the reduction of skin cancer is a factor that is largely considered when new greenspaces are build. A national park
8505-440: The park include a shelter shed ( c. 1920 s) near the corner of Oxford and Stuart Streets, Girl Guides' Hall (1950s), former Scout Hut (1950s – now a soccer club), senior citizens' club ( c. 1983 ), public toilets (1980s) and canteen (1980s). The c. 1920 s shelter shed is an open-sided structure, with timber posts with winged brackets supporting a short-ridged roof of corrugated iron. The soccer club
8610-430: The park is grazed by animals, but they are excluded from the garden. Flat roof Flat roofs exist all over the world, and each area has its own tradition or preference for materials used. In warmer climates, where there is less rainfall and freezing is unlikely to occur, many flat roofs are simply built of masonry or concrete and this is good at keeping out the heat of the sun and cheap and easy to build where timber
8715-627: The past hundred and seventy years, but these authorities have no statutory duty to fund or maintain these public parks. In 2016 the Heritage Lottery Fund 's State of UK Public Parks reported that "92 per cent of park managers report their maintenance budgets have reduced in the past three years and 95 per cent expect their funding will continue to reduce". Another early public park is the Peel Park, Salford , England opened on August 22, 1846. Another possible claimant for status as
8820-460: The plasticizers that had been removed by advanced methods in the distillation process. The two most common modifiers are atactic polypropylene (APP) from Italy and styrene-butadiene-styrene (SBS) from France. The United States started developing modified bitumen compounds in the late 1970s and early 1980s. APP was added to asphalt to enhance aging characteristics and was applied to polyester, fiberglass, or polyester and fiberglass membranes to form
8925-475: The principal influences on Olmsted and Calvert's design for New York's Central Park of 1857. There are around an estimated 27,000 public parks in the United Kingdom , with around 2.6 billion visits to parks each year. Many are of cultural and historical interest, with 300 registered by Historic England as of national importance. Most public parks have been provided and run by local authorities over
9030-592: The product, followed within a couple years by nearly every major manufacturer. As a result, CSPE and CPE are no longer available in the US as a full roof membrane, and repair materials are extremely rare or expensive compared to other membranes. Modified bitumen membranes are hybrid roof systems that combine the high technology formulation and prefabrication benefits of single-ply with the traditional roofing installation techniques used in built-up roofing. The membranes consist of factory-fabricated layers of asphalt, modified using
9135-487: The public. Hunting parks were originally areas maintained as open space where residences, industry and farming were not allowed, often originally so that nobility might have a place to hunt – see medieval deer park . These were known for instance, as deer parks (deer being originally a term meaning any wild animal). Many country houses in Great Britain and Ireland still have parks of this sort, which since
9240-428: The rain is absorbed into the soil/roof medium and runs off the roof bit by bit as the roof becomes soaked. A modern (since the 1960s) development in the construction of decks, including flat-roof decks, especially when used as living area or the roof of a commercial structure, is to build a composite steel deck . Asphalt is an aliphatic compound and in almost all cases a byproduct of the oil industry. Some asphalt
9345-435: The reality). A linear park is a park that has a much greater length than width. A typical example of a linear park is a section of a former railway that has been converted into a park called a rail trail or greenway (i.e. the tracks removed, vegetation allowed to grow back). Parks are sometimes made out of oddly shaped areas of land, much like the vacant lots that often become city neighborhood parks. Linked parks may form
9450-526: The roof membrane. On some membranes, even stone or concrete paving can be fitted. For one-off works, old carpet or smooth wooden planks for workers to walk or stand on will usually provide reasonable protection. Modernist architecture often viewed the flat roof as a living area. Le Corbusier 's theoretical works, particularly Vers une Architecture, and the influential Villa Savoye and Unité d'Habitation prominently feature rooftop terraces . That said, Villa Savoye's roof began leaking almost immediately after
9555-844: The roof. Detailing of these systems also plays a part in success or failure: In some systems ready-made details (such as internal and external corners, through-roof pipe flashings, cable or skylight flashings etc.) are available from the membrane manufacturer and can be well bonded to the main sheet, whereas with materials such as tar papers this is usually not the case – a fitter has to construct these shapes on-site. Success depends largely on their levels of skill, enthusiasm and training – results can vary hugely. Metals are also used for flat roofs: lead (welded or folded-seamed), tin (folded, soldered or folded-seamed) or copper. These are often expensive options and vulnerable to being stolen and sold as scrap metal. Flat roofs tend to be sensitive to human traffic. Anything which produces
9660-555: The roofing industry as "IRMA" roofs, for "inverted roof membrane assembly". "IRMA" as a roofing term is a genericized trademark . Originally, "IRMA" was a registered trademark of the Dow Chemical Company and stood for "Insulated Roof Membrane Assembly" and referred to PMRs assembled using Dow brand extruded polystyrene insulation. Grass or turf roofs have been around since the Viking times if not far earlier and make for
9765-467: The roofing, preventing water from running underneath the roofing and preventing the gravel surfacing from washing off in heavy rains. In some microclimates or shaded areas felt roofs can last well in relation to the cost of materials purchase and cost of laying them. The cost of membranes such as EPDM rubber has come down over recent years . If a leak does occur on a flat roof, damage often goes unnoticed for considerable time as water penetrates and soaks
9870-715: The safe confines of villages and towns. The most famous US example of a city park that evolved from this practice is the Boston Common in Boston, Massachusetts (1634). With the Industrial Revolution parks took on a new meaning as areas set aside to preserve a sense of nature in the cities and towns. Sporting activity came to be a major use for these urban parks. Areas of outstanding natural beauty were also set aside as national parks to prevent them from being spoiled by uncontrolled development. Park design
9975-639: The sub-national levels of government. In Brazil , the United States , and some states in Mexico , as well as in the Australian state of Victoria , these are known as state parks, whereas in Argentina , Canada and South Korea , they are known as provincial or territorial parks. In the United States, it is also common for individual counties to run parks, these are known as county parks . A park
10080-564: The surviving memorial trees are located along Oxford Street. The grandstand on the Godwin Street side was built about 1923 through local fund raising efforts. It has been suggested that the architect was George Henry Male Addison , who designed the nearby Bulimba ferry wharf building. In 1925, the park became the property of the Brisbane City Council , following the creation of Greater Brisbane. A shelter shed near
10185-456: The tar to weather and sun. UV rays lead to material failures such as cracking and blistering, and eventually water gets in. Roofing felts are usually a 'paper' or fiber material impregnated in bitumen. As gravel cannot protect tarpaper surfaces where they rise vertically from the roof such as on parapet walls or upstands, the felts are usually coated with bitumen and protected by sheet metal flashings called gravel stops. The gravel stop terminates
10290-546: The world are joining to support local parks that have suffered from urban decay and government neglect. Passive recreation typically requires less management which can be provided at lower costs than active recreation. Some open space managers provide trails for physical activity in the form of walking, running, horse riding, mountain biking, snowshoeing, or cross-country skiing; or activities such as observing nature, bird watching, painting, photography, or picnicking. Limiting park or open space use to passive recreation over all or
10395-417: The world for flat and low-slope roofs due to its exceptional durability, flexibility, and waterproofing capabilities. Key Features of Butynol Roofing Butynol Roll Sizes and Weights Butynol roofing membranes are available in different sizes and weights to accommodate various needs: 17.86m roll x 1.0mm (30 kg) Black 17.86m roll x 1.5mm (45 kg) Black and Grey Butynol Roofing Usage Butynol
10500-470: The world's first public park is Boston Common (Boston, Massachusetts, US), set aside in 1634, whose first recreational promenade, Tremont Mall, dates from 1728. True park status for the entire common seems to have emerged no later than 1830, when the grazing of cows was ended and renaming the Common as Washington Park was proposed (renaming the bordering Sentry Street to Park Street in 1808 already acknowledged
10605-487: Was Mackinac Island , gazetted in 1875. Australia 's Royal National Park , established in 1879, was the world's second officially established national park. The largest national park in the world is the Northeast Greenland National Park , which was established in 1974 and currently protects 972,001 km (375,000 sq mi). In some Federal systems , many parks are managed by
10710-529: Was closely followed by Princes Park in the Liverpool suburb of Toxteth , laid out to the designs of Joseph Paxton from 1842 and opened in 1843. The land on which the Princes park was built was purchased by Richard Vaughan Yates, an iron merchant and philanthropist, in 1841 for £50,000. The creation of Princes Park showed great foresight and introduced a number of highly influential ideas. First and foremost
10815-436: Was enhanced by landscape architects such as Capability Brown and Humphry Repton . The French formal garden such as designed by André Le Nôtre at Versailles is an earlier and elaborate example. As cities became crowded, private hunting grounds became places for the public. Early opportunities for the creation of urban parks in both Europe and the United States grew out of medieval practice to secure pasture lands within
10920-400: Was strictly forbidden for commoners to hunt animals in these deer parks. These game preserves evolved into landscaped parks set around mansions and country houses from the sixteenth century onwards. These may have served as hunting grounds but they also proclaimed the owner's wealth and status. An aesthetic of landscape design began in these stately home parks where the natural landscape
11025-503: Was the provision of open space for the benefit of townspeople and local residents within an area that was being rapidly built up. Secondly it took the concept of the designed landscape as a setting for the suburban domicile, an idea pioneered by John Nash at Regent's Park , and re-fashioned it for the provincial town in a most original way. Nash's remodeling of St James's Park from 1827 and the sequence of processional routes he created to link The Mall with Regent's Park completely transformed
