kirkieb Posted November 18, 2017 Share Posted November 18, 2017 Have a Townhouse and after a little research realise the very stuff used to keep heat out is in fact been sprayed entirely over the under side of my roof. All vents,have been sealed. Just found out Tiles in Thailand are designed to allow ceiling heat to escape. Why these clowns sprayed the entire Roof is beyond me. Having lived in Tropical Queensland most of my life know two things need insulation and need heat to escape. Insulation on roofs should be on the ceiling especially if the tiles are designed to allow air flow. Alum foil or sisalation are great if the roof isnt designed to have air flow. So How do you remove this stuff OR Any ideas short of replacing the entire roof and starting again. Stuff is like concrete Link to comment Share on other sites More sharing options...

As as I know some reasons are to stop tiles slipping/leaking, and to prevent wildlife from getting into the loft space. Link to comment Share on other sites More sharing options...
maxpower Posted November 18, 2017 Share Posted November 18, 2017 My brothers neighbor near Pattaya has the same problem and is in the process of installing new tiles and steel work that got corroded by trapped water in pockets created by the foam.

Kwasaki Posted November 18, 2017 Share Posted November 18, 2017 What shape is your roof. ? What roof tiles are they. ? Have you got soffits. ? Link to comment Share on other sites More sharing options...
carlyai Posted November 18, 2017 Share Posted November 18, 2017 I have sprayed roof in the Pattaya house and it makes the place a lot cooler, in my opinion.Another good thing about it is it makes the tiles nearly impossible to remove which stops the robbers gaining easy access to your house by just removing a few tiles.One thing you learn is never go into the roof space of a old house in Thailand. Mine is just a mess of bad building practices and sub standard wiring.I think to remove the insulation you need to put on a new tiled roof.

kirkieb Posted November 28, 2017 Author Share Posted November 28, 2017 Problem is they sprayed all the venting aswell. So now Im looking at installing a solar Exhaust Fan for the Attic area . Cheaper than retiling the roof as roof is in excellent condition just not ventilation Link to comment Share on other sites More sharing options...
carlyai Posted November 28, 2017 Share Posted November 28, 2017 You can get the tiles off with some hard work. Should be able to get enough off for the fan.Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...
