Pool House Expansion Project, Day Forty, 20/11/15

All of a sudden, it looks like a house.

Day Forty, 20 November, 2015

Just This morning, the house magically transformed. All it took was the addition of the zinc roofing pieces to actually be up on the roof.

To get to that point took a lot of work, due, in no small part, to Omar's expert leadership and direction. Here, he's taking a final measurement to figure out the desired overhand of the zinc pieces.
Omar Measuring Roofing Panel Spacing
 Early in the morning, well, around 8:00 AM, the crew is still working to finish the eave extensions.
Working On the Eave Extensions
I just stepped out on the porch of our current house, the Mennonite house, and here's what I saw. The first piece of zinc going up on the roof.
First Panel Going Up
 A little adjustment here and there and it's ready to be screwed into the trusses and cross braces.
Checking the Panel
 Once the first one is up and in position, the others follow along rather quickly, as you can see below.
Three Panels Up
 And, just like that, another one is hoisted up into place.
And Another One Gues Up
Here's a view of the roof from the underside. It's amazing that it's already starting to feel cooler under the roof. That was kind of the idea in the first place. It's nice to see our design actually taking shape and beginning to function the way we hoped it would as we were drawing it in the first place.
Looking At Roof From the Underside
Here, Errol is ready to grab the next piece of zinc as it is pushed up to him. Each piece weighs on the order of 75-pounds.
Errol Waiting For the Zinc
Here they're fitting the underneat foam to the underneath side of the zinc. It actually is adhered to the drip rail, so that it fits snuggly and conforms to the shape of the zinc piece directly above.
Fitting the Inside Foam
The indiviual pieces of zinc, heavy as they are, still have to be manhandled on their way up onto the roof. Even though they're 26-gauge, as they're being carried and positioned, care still has to be taken not to bend or crease them.
Another Piece is on the Way
That piece is working its way up the roof. One slip could spell disaster for the workers down below, so concentration to the task at hand is paramount.
Magically Up On the Roof
And a few tugs to get the piece into the correct position, overlapping its neighbor by about two-inches, it's then ready to be screwed down.
Giving It Some Last Minute Tugs
Even up on the roof, care must be taken so as not to damage the pieces. Once they're screwed down, they then become fairly strong and resistant to damage.
Twisting and Turning It'll Get There
From underneath, watching the zinc move up the roof into its final position, also gives a good view of the diagonal bracing. This really helps make the trusses very rigid.
More Diagonal Bracing
 We pretty much have a roof over the house now.
Almost A Complete Roof
From up on our Mennonite house porch, it looks outstanding. A real roof.
Looks Like A Real Roof
There's many more photos than appear in each posting. You can see all the photos of the construction project on Flickr at: https://www.flickr.com/gp/winjama/0wVc3s. There will be new photos added each day of the project.


  1. That blue color is very smart looking. The roof definitely makes it "real", what a transformation. Are you going to add insulation? The foil-backed thin foam insulation that comes in rolls worked wonderfully well for us.

  2. Hi Wilma,

    Thanks for the suggestion about the foil-backed insulation. I'm assuming you mean the foil-backed bubble wrap sort of insulation? We have that in our Mennonite house - 2 layers in the attic and one in the outside walls.

    I really don't know at this stage what insulation Carl is contemplating. We've been really happy with the foil stuff. I'll mention it to him. Thanks for the reminder.

    Roof is almost completely done now. They're throwing stone-dust mortar at the outside walls, so that' looking good already. Hopefully, progress will continue.


  3. Dave, looks great! The insulation Wilma and I used is similar to Reflectix solid gel insulation in a 2 layer aluminum sandwich. If you search on Home Depot you can find this, although I got much larger rolls from an industrial supplier (who/where I cannot recall). In any case it dropped the temperature in the second floor loft at least 10 degrees immediately.


  4. Hi Dennis,

    Thanks for the comment. A gel insulation, eh? That temperature difference is huge. Sounds intriguing. We've been heading over to Home Depot, Chetumal every week or so since this project started, so I'll look it up. Thanks for the information.


    1. Here is a link to the post I did about the effectiveness of the foil insulation. It is amazing! http://southenglishtown.blogspot.com/2015/09/sunshine-in-rainy-season.html

    2. Hi Wilma,

      Thanks for the link. Carl and I will be going over to Home Depot in a few days. Insulation is one of the things we'll be looking at. We have similar insulation in our Mennonite house, using the bubble plastic insulation just under the zinc. We didn't do that here (mistake), but I'm going to definitely look at the foam for between the rafters, and maybe they're have the other in a wide enough sheet that we can staple it to the trusses up near the zinc. Better late than never.
      Thanks again.
