Hi there,
I have a traditional roof tile (I think they are of cement but am not sure of a specific name for it).
I would like to put some oil or paint that can extend my roof lifespan.
Also, some of my roof tiles are broken and I want to know how can I fix the.
Please suggest me something cheap and best I can get to put on my roof that will be advantageous and won't change the existing roof tile color as I live in a townhouse in Victoria.


Thankyou,
