On my next trip down I must bring the roofing material for the upper section. I am open to all possibilities and suggestions. Remember, this is just
a fish shack (I keep reminding myself over and over again) for occational use. The rafters are so out-of-level but was not noticeable when it was a
palapa roof. I am leaning away from rolled roofing or asphalt shingles or anything that will lay flat to the plywood as it will really show the sags.
Also, exactly where do I buy roofing material in TJ or Ensenada?
If you see anything that makes you say, "Boy, that guy really needs to fix this"; fire away.

well...here it goes
...rafters are spread too far a part
...plywood is not staggered and is up and down instead of sideways
...the beam for the patio is WAY too small
...there's no facia board to put a metal flashing on to "flip out" the water when it rains...
here's what i would do...
paint the ceiling inside first to hide the ulgy wood...
cover the roof with 30# black felt
nothing heavier because its not a strong base
then...
put new palapa leaves back on
cross your fingers and it will last ten yearsAl G - 11-13-2007 at 07:14 AM
Bob...you saved me alot of typingDENNIS - 11-13-2007 at 07:30 AM
Roll roofing comes in various weights. Before US roofing products were readily available in Mexico, the default product would cover two squares per
roll, 200 square feet. The newer products cover only one square and the roll is the same size. The old is half as thick, half as heavy, shorter
life span but, it'll keep the rain out. It's still available all over the place.
That roof of yours is really steep and will be a bear to cover. Roll roofing can go on vertically but, you have to make the seams water tight. I
know you don't want to hear it but, I'd be considering a new roof design. In the long run, maybe not so long, it will save you a lot of grief and
money.Russ - 11-13-2007 at 09:40 AM
Sorry to say this but, I think Dennis is right, you might want to lower the pitch. With the open air building you have, another way to go is 2x10 or
4x6 rafters with maxiteja over that. No plywood. But if you're in a high wind area Plywood is best. But treat the plywood with a sealer before you
nail it down. Maxiteja can be painted any color. I have it on my patio roof and used 4x6 rafters. It comes in up to 23 foot lenths (7meters). No
hurricane damage in 6 years without the plywood underlayment. Best of luck!Bajajorge - 11-13-2007 at 10:12 AM
The kind that keeps the rain out.Paulina - 11-13-2007 at 01:30 PM

Yeah...it sounds good. If that's the chosen option, somebody had better know all there is to know about building roofs. Even flat concrete roofs
have to be sealed. Water has to roll of a roof. The longer it sits there, the more leaks you WILL have. A small pitch with a level sundeck built
above will work.Santiago - 11-13-2007 at 02:17 PM

Arn't you glad you asked?

Dennis,
Most everyone in that camp has the type of roof/deck that Soulpatch was refering too. With the amount of construction types that have places there, it
should be pretty easy to follow by example.

Just look for the roofs that don't leak.Paulina - 11-13-2007 at 02:44 PM
Wind is the biggest problema. A year ago a portion of our deck finally took off like the air foil it was fashioned after. It only took a little over
10 years, but boy did it fly!Diver - 11-13-2007 at 02:51 PM
How about corugated metal ?
At that pitch, you could lay it horizontally and shim the low spots between the ply and the roofing so it wouldn't show inside.
They make the roofing in galvanized and some plastics and fiberglass.DENNIS - 11-13-2007 at 03:06 PM
Oh boy....When the wind gets ahold of that stuff, it flys around like knife blades. Besides, IF it rains, it's noisy.Santiago - 11-13-2007 at 04:00 PM
To be honest with you I was pretty much going to use roll roofing and put palm leaves back on but I just wanted to see what else was going on. I
only want to get 5 years or so and then I'm gonna rip the whole thing off and start over. I was quoted 5 pesos per palm frond for material only -
does this seem right? Little high I thought.
The 'plywood' is some combination of OSB and chip board. The weird thing is the dark stripes are paint over the span tables that are always printed
on plywood. Why would someone go to the trouble of covering it up? 16 sheets cost $2080 pesos which is pretty cheap 1/2" ply. On the front the
plywood does span across the trusses, but in the back the rafter length was exactly 8' long so I guess it was just a lot easier.....
Oh by the way - I think I did something that borders on genius: I was sitting under the old palapa roof cussing at the sparrows roosting on top of
the 2X6 rafters where they just have enough room because the cardon 'sheating' leaves about 1-1/2" space. Crap all over my new tile floor. When they
tore off the old palm fronds I had them cut extra cardons to sit on top of the rafters between the cardons that hold the palm fronds - thus removing
the roosting spot. Next evening the sparrows flew up and could not land. Went next door and roosted on my neighbor's and crapped all over their
floor. I felt very smug.Diver - 11-13-2007 at 09:18 PM
Striping over the span marks on ply or osb means that the product did not meet specs. They call them blows. Usually it's because the glue has not set
to an even uniformity or thickness. Not recommended for structural use.

I am glad Diver brought that up(blows)...a safe way to get it to last a little longer is to use anodized wood screws every 6 " before tar paper, and
make sure it lapped horizontal from the bottom up also double at ridge. Have never seen palapa over plywood, but I am sure it could be stapled down.

Kathleen.....
You should consider the dog activity on asphalt roofing. You have three active dogs and they could cut down the life of your roof by half or more.
Their clawed feet tear up the surface. I'm speaking from experience.bajabound2005 - 11-14-2007 at 08:07 AM
Only Barney does the roof -- and you can see what he does there. Let sleeping dogs lie!
