sead Posted February 25, 2021 Share Posted February 25, 2021 So now im on with my roof but i seems to calculate something wrong or the builders are. The tiles are fibercement. 1,2m x 0.5m= 0.6sqm roof is going to be 13m x 18m and hight 2.5. ive calculated 18x13x0,6=140 tiles. With overlapping about 200. And someone calculated 468 tiles. Someone give me some help here please Link to comment Share on other sites More sharing options...

Someone give me some help here please My advice if you haven't started to build yet go for terracota tiles Fibercement is cheaper and lighter however the tiles are more fragile and need to be replaced after a while.. The heat insulation is pretty bad too. For your calculation it seems the builder or the shop have planned very large it could be also a mistake. Ask to the shop if you can return the tiles you don't use at the end of the build, Most of the shops are ok with that. (It could be also someone around you ermm errmm wanting to have a new roof for free thinking you will not notice the diference) Link to comment Share on other sites More sharing options...

Someone give me some help here please should be the total area divided by the area of the tile i.e. (18 x 13)/0.6 = 390. THis is the absolute minimum with no overlapping which you will of course need. Looks like the contractor is probably right Edited February 25, 2021 by upu2 1 Link to comment Share on other sites More sharing options...

steve187 Posted February 26, 2021 Share Posted February 26, 2021 i make it 468 18 x 13 = 234 each tile allowing for overlap will cover .5m so 468 Link to comment Share on other sites More sharing options...

With overlapping about 200. And someone calculated 468 tiles. The 0.6 m2 is not the cover area, deductions of side lap and overlap are required. 13 M x 18 M = 234 m2. need slope and width of roof to calculate exactly, any ridge.? 468 sounds about right at a guess and you always need overs to allow for breakage and cuts if any. With 200 mm lap your m2 coverage of the roof sheet is aprox 0.3 m2 intermediately. Edited February 26, 2021 by Kwasaki Link to comment Share on other sites More sharing options...

Ty for answer You are welcome as i said the terracotta tiles are heavier so this requires a reinforced framing i build 2 houses in Thailand, one with fibrocement tiles and one with terracota, the first one was an oven inside the second was ok, even without aircon. plus i had to replace most of the fibrocement tiles after the first violent storm so at the end of the day the cost was the same if i had to build a 3 third house i will go for terracota without any hesitation And yeah for the ''standart practice'' you need to oversee absolutely everything here and be present on the site at every minute of the built, every time i was absent even for only few hours. the Thais tried to cut the corners on something Edited February 26, 2021 by kingofthemountain Link to comment Share on other sites More sharing options...

The terracotta tiles don't retain heat after the sundown for as long as fibrocement tiles do, making them a better option in a hot climate. But still are not the best option thermally for a hot climate roof. Link to comment Share on other sites More sharing options...
