1, flat to slope of the top
Flat to slope of the top floor, in the living actually have the effect of "sub-roof". Not only is the waterproof effect better, but also because of the existence of the sloping roof, summer air-conditioning costs are relatively less. Waterproofing and insulation are both better.
2, send attic or other things
Some developers in order to more convenient to sell the top floor, will build a small attic, or send terrace or sun room. Then these top floors are also available to buy. The reason is simple: waterproofing and insulation issues would not be important.
3, cheap enough to buy
Some of the top floor, the developer makes a lot of profits, a lot of cheap can also cover a lot of late costs. Now the house is very expensive, if the top floor is cheaper than other floors 5-10%, or 10% more, then of course you can buy.
What should I pay attention to when buying a penthouse?
1, look at the roof
Slope roof is now the international health of residential roof design advocated by the heat insulation, waterproof have a better effect. In addition to the advantages of not easily storing water and effectively preventing seepage and leakage of rain, the level of heat insulation of the top floor of the house is also very good because the sloped part is elevated.
2, look at the penthouse design structure and materials
The big taboo of the penthouse is the heat insulation and waterproof performance is not good, so want to buy the penthouse to pay special attention to the penthouse design structure and materials, you can ask the developer to provide the penthouse design, construction information to see whether it meets the building standards. If the roof is not sloped but flat roof, home buyers should pay special attention to the insulation of the house, the way to judge mainly for visual inspection.
3, look at the water seepage and drainage after the rain
Rainfall can test the quality of construction of housing, especially the top floor of the housing stock, it is better to go to see the house after a heavy rain. If the building quality of the top floor of the housing stock is not pass, drainage performance is not pass, the house windows of the airtightness is not good or the wall roof is not tight, may lead to the top floor of the house water seepage.
4, look at the water pressure
Many penthouses due to the height of the floor, water pressure is insufficient, the tap water flow is small, and affects the gas water heater ignition, so the water pressure problem must be concerned. The current building can go to the top floor directly release water to view, someone moved into the building, you can first to have moved into the top floor owners to understand the water pressure. If it is a period building, you should ask the developer to provide information on the materials used for water pipes.
