Mould

More and more inquiries regarding moulds growing on ceiling linings. Most owners regard moulds on ceiling as signs of roof leaks.
In most cases moulds growing on ceiling lining has got little if any relationship with roof leaks and often caused by combination of a number of reasons such as:

  1. Lack of or insufficient or unevenly distributed ceiling insulation
  2. Poor home natural or mechanical ventilation
  3. Poor subfloor ventilation
  4. Poor ceiling lining material or coating
  5. Lack of general maintenance
  6. Excessive surrounding vegetation
  7. and other factors 
It normally associated with old houses and not too hard for owners to find out reasons by themselves.
In most cases the solution would be a combination of a total roof service by a roof maintenance professional, retro fit of new ceiling and under floor insulation, installation of heat pump and/or home ventilation system, general cleaning, landscaping maintenance and so on.

  1. 屋顶有霉斑的原因一般是几个因素的综合:
    棚顶保温棉级别小,或者没有保温
    缺乏自然或者其他通风设施
    地板下面缺乏保温
    天花板材料和涂漆的质量
    忽略平时的清洁维护
    房子周围树木过多
    还有其他可能的因素
    因此,解决方案往往不是一种措施
