I would agree, it looks wrong. Almost looks like a spill and not a carefully applied coating. Maybe its the pics or the angle of them, but it looks like a spill not a coating at all to me.

Did you mix the buckets well prior to application? If not then you oiled your roof very nicely. Was this picture taken immediately after application?
Could just be the picture.

Basically, if your roof looks silver then yes, you did it correctly. Hard to mess up.

Does your roof look bright and shiny silver?

It looks like you need another coat. Did the installer use the recommended sqf application rate because it looks a bit thin or it was not mixed very well.

The white will reflect more of the heat and stay cooler.

Looks thin to me too. I'll ask about the sqf app rate. Contractor got very defensive when I told him it looked wrong.

Just looks like he never stired it up enough.
Takes more then just a stick to stir it up.

Good point. Almost looks like it was 'thrown' on right out of the container.

Not trying to defend a possible poor application but it almost looks like moisture (dew or frost) got on the coating before it was completely dry. In any event, another coat when the weather is favorable for the paint to dry would be the way to go.

It didn't rain after coating. But it was damp. Maybe that had an affect.

If it was damp then yes it's wrong, and no it doesn't look like it was mixed up at all, it should be bright. and it might be a bit thin.

Aluminum roof coating is basically aluminum flakes dumped into asphalt cutback. The flakes all settle to the bottom in big clumps. The best approach is to mix this stuff up with a commercial grade metal Propeller type paint mixer on a half inch electric drill, and you have to work it around the bottom of the can. It has to be mixed pretty much continuously during application, as the flakes sink to the bottom fast.

You can re-coat to even it out but what you have does not look too awful bad. It is a roof, not a piano.

That isn't the way it's supposed to look.
Looks like they didn't "stir"/mix it correctly - never seen those "streaks"/
discoloration - when it's done right!
Another coat!

"RF"

(Tell them to "roller" it on, using a "thick-napped" roller"!)
Heavy-duty drill with a mixer-head on it - mix the "crop" out of it!
