What is the best brand for problematic roof
I saw China product... But not sure
Nippon although very famous, I don't think they are good specifically for roof issue. Most are acrylic baswd

I'm looking for certain criteria
Can reflect sunray
Allow water to flow nicely like flow on the mirroe
Long lasting

Mapei

Best is jangan cat

best is change roof tiles lol i use jotun. so far its ok. but still its water based xD

China brand ?
No thanks

Go for sika

Put solar panel,
Solve ur heat n tnb bill .

Serious .. I hv spoken to a lot of painters and their advise is dont paint the roof ..

replacing is too expensive lor

Don't paint. No joke. Bad experience after painting will hit you probably after 1.5-2 years.
