Removing sprayed Insulation from Tiles

[kirkieb]

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

As as I know some reasons are to stop tiles slipping/leaking, and to prevent wildlife from getting into the loft space.

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.

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.

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

You can get the tiles off with some hard work. Should be able to get enough off for the fan.
