I just got my flat roof done back in October, my roofer told me I will have to wait 2-3yrs to silver coat it. Is that true?

What kind of flat roof?

I’m not sure what type it is but I was told it’s good for 12-15 years.

Here is a pic of it

I would think an elastomeric coating would be better than an oil base silver coating.

+1. I would look into something like hydrostop instead of henrys.

So do I have to wait before putting a silver/white coat?

It's probably a good idea to wait. With asphalt driveways you are supposed to let it weather for a year before you seal them. I don't know for sure about your roofing but would assume your installer knew.

Better Springtime project anyway. If the roof isn't leaking, do it in the spring when the temps are more ideal.

Well my roof is only about 3 months old, so no leak for sure. I just want to know why I needed to wait for a silver/white coat on a new roof that’s all.

There are probably chemicals or substances that will leach out of the new material as it ages. Those substances could affect how any coating bonds or looks.

Good couple of months in direct sunlight are burning off just about whatever is left in them from the manufacturing.

I know Neogard make a elastomeric coating that is white, and 90% or more reflective, even comes with a 30 year warranty. Is designed to go over epdm rubber roofs. Not sure what your roof material is. That might be something to look in to.

2-3 weeks, not years. Just gotta let it flash off decently for the silvercoat to adhere without the asphalt bleeding through. No need to use any expensive roof coating on a new roof. Just basic cheap silver coat and maintain it every few years and it will maximize the life of your new roof. All it needs to do is protect your membrane from it's worst enemies, weather and sun.
