This is the most common type of roof. The pointed roof is composed of two sides sloping down from the same starting point, forming two triangles on either side of the house. Pointed roof houses are suitable for countries with weather conditions with a lot of rain or snow because the slope of the roof makes it easier for snow and rain to fall, making the roof less heavy. The pointed roof has a simple design, requires less materials, and is easy to construct, so the cost is low. At the same time, the space below the pointed roof is wide and airy, so it can be used as a storage space or an attic bedroom. However, the pointed roof is easily affected by strong winds, if not firmly reinforced, it is easy to fall because the wind is easy to blow into the space under the roof, causing the roof to fall. 2. Tower roof This is a type of roof with 4 sides sloping down, with the same slope and relatively light slope to create balance for the building. Usually a tower-shaped roof will have 2 triangular faces and two trapezoidal faces. The tower-shaped roof is common in European countries as well as Vietnam and architects often use this roof for villas or garden houses. Tower roofs are recommended for areas frequently affected by storms. However, because of the complex structure, this type of roof is difficult to maintain. 3. Rubber roof Rubber roofing is a cheap, green, and durable option. Rubber roofs are usually large panels, easy to install. Waterproof surface, perfect for areas with humid climates. However, the aesthetic of rubber roofing can be too simple for some homeowners who want a difference for the home. 4. Flat roof Flat roofs are a popular design for homes in warm or dry climates. This type of roof protects homeowners from heat and sunlight. However, it is not ideal for areas with a lot of rain. In addition, you can create a living area, garden or mini sports field on the roof. 5. Roof falls This type of roof slopes in one direction. It can continue the slope of an existing roof, or separate, similar to a shed roof. The roof seems to be raised, making the work very noticeable. This is a permanent roof because water, dust and particles roll off more easily. The construction also makes it tough, able to face the harsh elements. Skillion roofs are ideal for contemporary urban homes, galleries and other small commercial buildings. The shape of the roof will immediately catch the eye. 6. Butterfly roof The butterfly roof looks like an inversion of the standard pointed roof. The basic design looks like a letter “V” (or butterfly) when viewed from a distance. This roof was popular in the twentieth century and many architects liked to experiment with this unusual roof shape. 7. Salt box roof The salt box roof is a type of pointed roof in which one side of the roof has a much longer slope than the other. Buildings with this type of roof usually have two floors in the front and one in the back; adding a sloping back porch is a structure that simply extends the building. The salt box roof is ideal for various modern and contemporary homes. You can create a patio under the higher roof, turning it into a cozy sitting area. 8. Curved roof Curved roofs are not a contemporary design. It appeared in the early 1920s as a solution to maximize storage space in barns. Curved roof is back in the modern world because of its unusual shape. It has a simple construction, is perfect for windy areas, and is easy to customize. 9. Dome Based on the curved design, the dome has a high visual impact. It is commonly used for the construction of buildings of worship, but variations of it appear in residential houses. This roof is unique, energy efficient and provides a great surface for decoration. 10. Pyramid roof The pyramid roof is a variation of the pyramidal roof. This roof is common in modern Victorian homes. The pyramid roof is well suited for windy areas and comes with its own insulation benefits. It also drains quickly when it rains. 11. Serrated roof The serrated roof looks like a series of ridges when viewed from a distance. This roof is popular in warehouses and factories because it allows natural light in. In the 21st century, serrated roofs are gaining popularity thanks to the trend of bringing natural light into the home. 12. Canopy roof The bonnet roof is a variation of the pyramidal roof. The edges of the roof extend beyond the walls, creating a shaded area resembling a bonnet. Some bonnets have a slight slope at the bottom. In modern homes, the bonnet is extended further to create a terrace or patio. 13. Roof with metal roofing The metal roof provides durability and strength. This roof can last from 50 to 100 years if well maintained. Metal roofs are perfect for windy areas, lightweight and ideal for reinforcing old structures. However, when it rains, the sound on the roof will make homeowners extremely uncomfortable. 14. Asphalt roofing sheet Asphalt shingles are popular roofing materials, especially in North America. They are cheap, easy to install, and can reflect sunlight better to reduce heat inside the home. But asphalt roofs are prone to damage from hail and water, so it’s not a good solution in the long run. 15. Slate roof The slate roof is made of natural stone, creating an expensive and luxurious look. It lasts a long time and doesn’t catch fire too easily. However, the combination of weight and fragility makes slate roofs more difficult to maintain. 16. Green roof Green roofs act as a means of planting trees, a growing trend in environmentally conscious architecture. It helps to create insulation, absorb water and deliver more oxygen in your environment. Green roofs can be applied to traditional houses and modern buildings.

Chinese Truong Chinh 5B missile leaves its launch pad. According to this map, anywhere between 41 degrees North and 41 degrees South can be affected by the rocket’s debris. He said the boosters will enter Earth’s atmosphere as early as May 8. According to ROSCOSMOS, “a portion of the rocket will no longer exist in the dense gas layers of the atmosphere” but “individual non-flammable structural elements can reach the surface of the Earth”. Meanwhile, the Aerospace Corporation non-profit aerospace organization predicts, the time of the Chinese missile crashes to Earth will occur at dawn on 9/5 (international time), the error plus – minus in 28 hours. They also published a map of the potential impact area – relevant to the area provided by ROSCOSMOS. The Chinese missile’s orbital tilt is currently 41.5 degrees, meaning it could fall anywhere from the north relative to New York, Madrid and Beijing and as far south as southern Chile and Wellington. New Zealand, these are all regions with the highest population densities in the world. The ROSCOSMOS map shows the drop zone of the Chinese missile’s center. Speaking to the press, US Defense Secretary Lloyd Austin expressed his hope that the Chinese missile will fall into the ocean and it is estimated that it will fall between May 8 and 9. On May 6, Mr. Austin said at this time, the US has no plans to shoot Chinese missile debris that is expected to fall back into the atmosphere this weekend. Since the missile is traveling at an average speed of 7 km / s, it is difficult to predict where it will hit. US Department of Defense spokesman Mike Howard said the US Space Command was monitoring the missile’s trajectory. However, the US was only able to determine the exact point within a few hours before it fell. According to Howard, the 18th Space Control Squadron will provide daily updates on the missile’s position on the Space Track website. Ted Muelhaupt, an expert in space debris at the US-based nonprofit Aerospace Corporation, told ABC News that the central floor of the Truong Chinh 5B rocket was probably among 10 large objects. can fall to the planet into 1 piece. The bulldog has a central floor weighing 22 tons. China’s Long March 5B missile hull areas are likely to fall over the next few days. Photo: Aerospace Corporation According to SpaceNews, the 22-ton central deck of the Truong Chinh 5B missile is in a state of out of control and could fall to Earth. Instead of falling to the intended location at sea like the previous rockets, the central stage of the Truong Chinh 5B boosters began to rotate around the globe in China’s helplessness. On April 28, the China National Space Administration (CNSA) launched a Long March 5B booster rocket carrying a core module called “Thien Hoa” weighing 22.5 tons into space (part of the space station. Heavenly Palace). The launch went quite smoothly until the core of the missile suddenly deviated from its intended flight trajectory. It is known that the core layer of the body (weighing 19.6 tons, 30m long and 5m in diameter) is currently flying around in the LEO orbit at an extremely fast speed. According to a SPACECOM representative, the Chinese missile is currently flying at 162-306km above the ground, indicating that it has begun to gradually decrease altitude from 170-372km. Essentially the drag of the Earth’s atmosphere sooner or later pulls the upper missile body out of the LEO orbit, but with its erratic speed and trajectory it makes it possible to accurately predict the location and The moment the rocket will hit the ground becomes difficult.
