Yes I also had similar issue. Hairline cracks.... which is like the beginning of
leakage(ceepage) problems. They say "a stitch in time saves nine". So if you keep maintenance of the roof on yearly basis.... you safe from a lot of other problems... down in your house.
Elastomeric coating is bright on the first day, but in our case too much construction around and too much dust falling on the roof. That coating did a good job at sealing the cracks. It is not that elastic so they appear after a year. Then we get a litre more of this stuff and seal up the hairline cracks every year.
