Location is Miami Florida. I am going to repaint my house. Single story CBS (Concrete Block Stucco) with a concrete tile roof.
The concrete tile roof was partially damaged during hurricane Wilma, the roofing company came out and repaired with some new tiles - same size same model but different color, since that was all they had in stock I was not in a position to be picky (roofing contractors are hard to find and book in our areas). So anyways I have now a roof with 80% old tiles, a little faded gray color and 20% new bright white tiles. I am considering repainting the roof.
After doing some research on the net, it seems there are a significant amount of people who thinks this is not a good idea because the paint will eventually break down and decompose after a short time under the extreme heat and rain in Florida.
SOMAY Product No. 992 - SOMAY Elastomeric "PATCH & SEAL" (Caulk) to seal all joints
Intermediate and Finish Coats:
SOMAY Product No. 842, SOMAY Elastomeric "ROOF MASTIC", Sealer & Protector Apply at 20 mils dry film thickness for each coat Color: White
Total: 40 mils dry film thickness for all 3 coats
So what I don't understand is this. When they said "Intermediate Step ... seal all joints" do they mean they seal the edge of each tile? So that there is no water to go under any tile? and 40 mils of all 3 coasts is very thick! This is like covering the roof completely with one continuous layer...right?

I think you're on the right track
far as one continuous layer..
i don't see the need
2 things
right! I agree.. 3mil is thick second, why not just goback to your original plan of sealing the concrete
you're not looking to waterproof the roof, just seal the concrete
sealers are super thin and soak into the block.. fuck all that prep shit.. i mean sure.. remove leaves and sticks and stuff.
crete sealers have a watery property.. hell! spray it on!
why not just tint the sealer.. make several applications and be done with it.
I'm in Hawaii [heavy UV] with a concrete shake-style tile roof. If you are simply adding a color coat to even out the look, skip the heavy prep. 1/3 the work and 1/3 the price. I've had fine results from simply applying a quality elastomeric coating with a heavy nap roller. Don't apply after a rain - you'll tend to get bubbles. [Of course, no better way to get a drizzle than to start a roof project.] Colors will fade in a few years [darker colors faster] but the results should be uniform.
Living in florida, same setup concrete block house, older tile roof. I'm of the mind if it aint broke dont fix it, paint it once you'll always be painting it. I look at this way, my roof is 15 years old, the original glazing which was baked on was baked off by the florida sun a long time ago. I would seriously doubt painting or sealing which I also considered would last more than a few years...figure baked on original coating maybe lasted 10 years, surely any other wont last but 5 years maybe which then will have to have it done again.
I've decided with these tile roofs its best to leave them alone, depending on how the tiles are put up there (sometimes they're nailed, sometimes held with a blob of morter) if morter, the more you're up there the more you're going to loosen them and the more that will want to slide down from vibrations,etc from storms, thunder, hurricanes, etc.
When I redid my house I contemplated coating the roof as it was pretty dirty. I decided against painting because I just dont see it lasting more than a few years. I had it pressured washed and wish I hadn't even did that, broke, loose tiles,etc. Anyways after pressure washing it it looked good, I thought about sealing it with concrete sealer because with the glazing gone all of the tiles are just dirt magnets since its open pore concrete now, but I doubted that stuff would last 1 summer so I didn't bother.
Though....my roof is the red stuff. White would drive me nuts, red when it gets dirty looks like dirty red, white just looks dirty...but doesn't absorb the heat as much.
My neighbor had his tile painted or coated after a partial replacement and it looks good. But I coat my pool deck (some type of acrylic modified cement kooldeck stuff) with a concrete stain...its birdcaged in from full sun exposure but with the heavy rains and sun it doesn't last more than 2 seasons before I have to recoat it again. I could be wrong, but I just dont see this kinda of stuff lasting ..

I would like to leave it alone, but the grey + white color is too distinct and it look bad. I have to do something...I wonder if I should use concrete stain or Elastomeric waterproofing paint.

I would give it a couple of years. I suspect that the colors will begin to match in time. I suspect that any paint or other product you use will be regretted in time. Consider the two different colors as a badge of courage of living through it all and a conversation item.
If you do decide to paint stain or whatever, do all the prep work very carefully. It is the most critical part of the whole project. BTW you do risk the change of damaging the roof doing this work, which is another reason not to do it.

it's an old joke, when its trying to rain you pencil in a circle on the roof.. if you get more than 25 drops in the circle you get to come down. of course a good rain dance never hurts
heyah heyah heyah.. you gotta raise one hand and do a slight shimmey - works every time
Are you sure the original tiles aren't white?..my neighbor has a white roof and everytime he has it pressured washed i'm amazed that it was actually white. No idea how they paint them, it would seem like concrete acid wash, then concrete stain would be longer lasting, but if your new tiles have some type of ceramic coating seems you would need something more paint like it would seem.
I think you're going to have to do some calling around on this. I just went out and looked at that nieghbors roof who had thiers painted or coated or whatever, its been 2 years and still looks very good...so i dunno maybe they can get 8 years or so out of whatever it is they do? Theres alot of houses arond here who do it, i'm just nervous of creating another major chore..

that's a good idea
pressure wash them first maybe they're actually white
