Henry's Tropi-cool is a very good product but it's white.

When you say roof 'deck', does that mean it needs to hold up to foot traffic and furniture?
If you are not living on the edge, you are taking up too much space!
"Could do better if he tried!" Report card comments from most of my grade school teachers. Sadly, still true!

This is about the best "high security" lock for a steel door.

That being said, thieves will get into anything you put up. I had these on two outside storage rooms and they used a hand grinder to just cut the
whole thing off the door and frame. The game is to make it as difficult as possible to discourage the less than professional thief.
Living Large in Loreto. Off-grid and happy.

Yes, locks are to keep honest people honest.
Better to have a space in the garage with a "false" front to hide the most valuable stuff.
Alarms, lights and dogs help....

A really good product if your concrete isn't poured yet is Xypex C1000. This is an admixture that will self heal cracks up to 1/16" even years after
the concrete has set. We have used it in Baja and the states with good results, it is available from Hub and I think Whitecap.

Have the roof deck carefully chipped and prepped and then add a layer of cement with fiberglass additive and ensure the layer has proper level to
allow water drainage, do a final decorative coat or finish with tile.

Great question, due to the fact that 90% of people that pay for a roof deck, roof finish, etc., have issues in Baja, especially at locations such as
inside corners, areas that hold and drain water to other locations. #1 be smart and create the deck to have good drainage ( prior suggestion ) #2
design the deck to be counter flashed with sheet metal at the area where water can accumulate ( sorry if this is subjective, but heed my warning ie
make sure it runs off the deck / flat area ) #3 dont screw around with this particular phase, pay to have it completed properly and #4 the most
important - use a product call " West Coat " sold in San Diego and transport the product to your house, they have specific videos indicating exact
installation instructions, even if you are not up to the task of doing the installation, show the video to the locals who will complete the
installation. I have extreamly good fourtune with my contractor n Mexico when I have taken the time to do my research, and then take the time to
either show a video or explain a step by step process. Granted I am in the construction industry and may have an advantage to describe specific tasks,
but for what its worth, the problems in Mexico, borne of bad construction are no more simple of the fact that they are learning what gringos want and
request. Kind of long and drawn out here, but, have patience and don't have the " need it done yesterday " mentallity, remember, your in Mexicoooo. By
and large, most workers in Mex want and strive to do a good job, unless of coarse you make a bad desicion with who you hire, Bien suerte amigo

gnukis and chumlee have good ideas
remember on a flat roof you need 1 inch for every 8 feet for drainage
1 inch every 4 feet is even better
never assume your builder will get this right
you NEED to check it before the pour
as for cement roofs...they ALL crack...
the earth moves and the building sways
there is ALWAYS maintenance
if you are not commited to a flat roof I would get a regular roof
mine are cement but are covered with 90 pound felt and Mexican tiles
they don't leak
the felt is the barrier...the tiles protect the felt
don't think you'll use that roof for a patio...that's a dream...you wont
in the summer its too hot
in the winter its windy
and you have to climb stairs to get there
its a dream to think you'll sit up there and have a drink...it wont happen...
build for the storms
hurricanes and thunder storms are not easy on the house
the sun is even worse
remember ALL cement cracks
don't ever assume a product topping will stop that because
it wont

Correct about it seldom getting used. I had ours covered with black tar, the kind used for under showers, and than had the whole area tiled. Did this
26 years ago and never had a problem.

1)The classical Mexican roof coating works fine and consists of
Tar coating covered by polyester fabric then coated with white roof elastomer. Best white coating is made by Henry and not available in CA, but can
be purchased in AZ. It is very resistant to pealing due to small water puddles. Expect to re coat every 5+ years or so.
2) Good luck the Mexican bad guys know how to get inside any garage door. A metal roll-up door is probably the most secure. After that all kinds of
DIY methods for any door would be acceptable since your method may be unfamiliar to the bad guys? A metal fabricated foldup would be unique and could
be made pretty secure?

One way to waterproof it is to put a roof over it. We had a second story concrete deck (but no room under it) for 10 years before Hurricane Odile.
Hardly ever used it. Way too hot in the summer and not fun at all in the wind.
We lost that patio and 1/3 of our house to flash flooding from the Hurricane. We rebuilt, but this time the patio has low walls and a roof over it.
The plan is to screen it in, but for 2 years now we have used it as is. It is perfect. It gives actual and psychological protection. Not much water
makes it to the floor (wooden decking this time). We use it most every day. About 4 o'clock with a deck of cards and a cool drink.
Just a thought...

Here a photos of the completed roof deck. I agree that Baja is often too hot or too windy and cool, so a partial covering made of metal frame that is
strong and secure makes it all come together.

Fireplace chimneys on ocean front homes need to be designed properly.
I have seen houses filled with smoke by renters that try to use the fireplace during winter storms.

Henry's tropicool
o.k. probably going to use this product on a roof deck that will be constructed soon. Having it sloped 2" per it's 10 ft as suggested, with
drainage channels. Thanks to all of your advisements. Others actual experience with longevity of this product? Henry's tropicool, that is. Fir
instance, suggest reapplying every how many years?
Best concrete caulk or glue to ship down with the load and keep on hand for roof cracks? Looked at others'torch down system and hated it, and
can't afford tiling.

Polyester white coatings have a variable life. Mine gets redone every 5 years for the roof with less than proper slope The steeper slope roofs are
good for much longer.
The thing to note is the poured concrete roofs will have areas with low spots. So the coating you choose must be able to deal with the puddles and
not peal up when getting wet. The only Henry product that meets that situation is #587. The Henry web site gives all the specs for each product for
you to review. #587 is not available in CA so I get mine in Yuma.
Concrete cracks are not an issue if a tar coating is used per Henry application instructions. Those details are also on the Henry web site.

Two or more coats of "empermeabilizante", sold in paint stores and some brands have they're own stores.
14 years, no leaks, (need to re-coat soon).
I walk on it, but not frequently.
