TOA Roof Sealing Paint.

[JeffersLos]

We're helping to fix up and renovate our old neighbor's house. The roof is leaking in places as the tiles (3mm) are old, and from underneath can see indirect light where they meet. Can see dark water marks on the wooden beams, but no real damage to the wood.

 

We recommended having it all retiled, but they're old and don't want to spend the money.

 

Other options are to try to seal it with either sealing tape or a paint sealer. 

 

TOA have this roof seal paint.

1. How good is it at sealing up old roof tiles that have small leaks coming through where they meet?

 

2. They are sold in 4Kg tubs. On average how many sqm would a 4Kg tub cover?

 

The roof is probably around 100sqm.

 

TIA.

Another option is for them to use a roof seal tape along where the tiles join.

Thanks.

 

For 100sqm they calculate it as needing 200kg of roof seal paint. 

 

50 tubs for 32000THB may be a bit much for them.

The main leak seems to be from a part of the ridge, would cementing the ridge tiles also be an option for them?

You might try again.  I used the calculator and got half that.  Same result with both products identified as roof sealer.

Look carefully at that product, I think it is for flat concrete roofs not tiles.
