请问大家,有用monier瓦片屋顶的么,上个房东留下来一张50年的保证书,是保证瓦片不腐烂不风化。房子是92年的,我惊讶的是,我在他们网站看到,他们的理论是苔藓从任何方面都不影响瓦片。还美曰其名add character。原文如下: Does lichen growth affect the durability of roof tiles?
In some climates, moss and lichen can grow on your tiles. They will not affect your tiles in any way, and can add character to your roof. However, if you prefer the clean lines of your tiles, both moss and lichen can be easily removed with high pressure water jet cleaning or by using other commercially available cleaning products. (Always consider the environment when using chemical products)
这个房顶目前很多地方是苔藓了,难看死了。不少公司都生产清除苔藓的清洁剂,而且都说苔藓影响瓦片,这真是公说公有理,婆说婆有理了??
另外当初帮我检查房子的公司是说,unglazed concrete and clay tlie roofs should be sealed with silicone at three to five-yearly interals to maintain waterproofness,但是我在monier公司网站看到,公司说他们的瓦片本身不需要保养,即使很多年基本不会porous(渗水)。作为屋顶保养,应该检查gutter, downpipes等等,言下之意,也不用每三到五年sealed with silicone来防水??
究竟我应该相信谁的啊,看的我这个外行一头雾水。谢谢指点。
