Leaky Tile Cement Fibre Roof.

[Issangeorge]

I have a roof composed of cement fibre tiles 65cm by 55 cm. My roof is very high and it is difficult to find someone willing to go up on it. It leaks badly at the ridges (there are four) I was wondering if there was some sort of foam that could be sprayed from the attic that would stop the leaks?

I'm sure that you can locate a roofing contractor who can sort the leaks, for a price.

The problem with the foam solutions (which are primarily sold as insulation) is that they tend to re-direct the water so that it simply appears elsewhere to cause damage

hello for small leaks made by screw you can use flintkote and use a paintbrush. 1kg about 140baht

for larger gaps which you mentioned at the ridge can buy Sika PU foam. about 300baht per 500ml can.

these repairs can be carried out from inside the attic
