Shipping Container Metal Roof - Episode 017

Well, to assemble the metal roof was simple. The hardest part about this task was to choose the roof.

We spent days and days going to stores to try to find a solution for the drainage on the top of our shipping container. We have seen polycarbonate roof, recyclable materials roof (the quality of these ones in Brazil in our opinion isn’t that good), galvanized sheet, among others. In the end, the best cost benefit and easy installation was the aluzinc roof. Even better, we could have a good material and we could have a perk of having the choice to add EPS under the roof to reduce the noise and the heat inside the shipping container (and it’s not that expensive). With this decision made it was time to call some stores and to visit some others. We finally found the best place to buy it, the same place where we buy the metals for the building.

Another decisions we needed to make were about the painting of the roof. We needed to decide if wanted to buy it already painted with epoxy paint that is was expensive or if we want to buy it with no painting and to paint it by ourselves with synthetic enamel, but we knew it would take a lot of our time to paint and the quality wouldn’t be the best one. In the end the seller told us that painting is not necessary and we decided not to paint it as this material should be rust proof and even without a paint it should last for many years. The final decision was: would we like to have the EPS already glued on the roof? It was a U$100 dollars extra for that. We decided to by the glue online to be cheaper and to glue it by ourselves. But, in our opinion, it was a terrible choice.

The glue gets hot and dry really fast and we have heard that 30 minutes later it was possible to move the pieces of roof around. The day we glued the EPS on the main pieces of the roof was the first day after daylight saving time (DST) or summer time (as we call in Brazil). So, it started getting dark 1 hour before. We didn’t realize that and we started gluing and it started getting dark and the plastic bag that we have the glue inside started ripping off, we needed to exchange plastic bag 3 times and in the end the glue was really dry. It was dark when we finish it. In the end Duca was applying the glue on the EPS while I was illuminating with the cell phone flashlight. To get worse, the forecast was saying that the next day it would be raining and we were afraid of getting the EPS wet. We tried to take the roof up to the top of the shipping container on the same day, but it wasn’t totally glued, we could listen to the noise of the EPS  falling apart off the roof. We decided to put one on the top of the other and put some joists on the top and another extra roof on the top of it.

Next day we tried to get there early to put a plastic on the top of everything in case of rain. We got, there, put the plastic, the rain came, stopped, came, stopped…  At the end this day the rain was coming and going and we put the roof for the top of the shipping container anyways.

The last decision was about how to move the roof into the top of the shipping container. We use a C clamp on each side of the roof and we tied a rope in them, this way we would hold the rope and to drag the roof up to the shipping container. It worked!

The tip we can give is: before taking the roof to the top of the shipping container think really well were each piece of the roof is going to be and give some names to decide which one you need to take first. Otherwise it can be really hard to organize them on the top of the shipping container as there is no much space to work.

After deciding every single material and solution for the installation it was really simple to instal.

So, to install our aluzinc roof the steps were: we measured the width of the roof and cut the sheets of metal to fit on place; we used the angle grinder to clean the edge that we had cut; cut the EPS; cut the EPS to leave space to put the roof on the top of the wood that will support the roof; we waited 12 hours and put the roof to the top of the shipping container ; we drag the roof into the top of the shipping container putting one on the top of the other; we organized the first and second one on place leaving some space without roof to work around without stepping on the top of the roof (it can bend the metal); we screwed the roof of the west container and then the roof of the east container going to the east to the west; we put some self adhesive asphalt on the top of the screws and on the edges between the roof and the wood.

And that was it!! The roof was finally on place!!! And it’s working!!! The water is going out of the top of our shipping container. We are sooooo happy that we finally made it!!!
