Man on a Hot Tin Roof

I like the idea that this fellow is possibly fixing hi parents or his own roof!

He has no knee pads. Sort of looks “too slim and fit” to be a general laborer!

This guy, while not a general laborer in the sense of that's his day job, does do all the work on his many properties. Metal roofs (standing seam) are popular here as well as hurricanes rarely affect them.

Great link, Jérôme!

Asher Kelman: Ceiling Steel​

We have a metal roof welded to a steel frame and then on top of that a 10” framed wooden covering for insulation bolted to a steel girder at the periphery anf covered with nailed 5/8” plywood and then asphalt shingles. The latter, I guess would fly away in a hurricane, but the roof would be easily repairable

I thought the picture was self-explaining.

As a translation:
  • blue is the wind
  • "toît en tôle" is the metal roof. They chose a round roof to minimize wind forces
  • the actual invention is the dark grey part, made of reinforced concrete. It protects the side of the roof from the wind while letting the water gets through. In that design, that part is reinforced (it must be as it will still receive the wind efforts).

I suppose it could be easier to simply make the end of the roof go downwards for half a meter or so and then connect it to the wall.

Thanks, Jérôme!

I did get that idea, but still a few of the words were new to me and hence my request!

In my design, I made a 10” high laminate of 18 glued layers of 1/8” marine plywood and faced it with stainless steel. It also similarly covers a gutter with a second gutter underneath for leaks built inside. The laminate is connected to 10” high vertical beams over the roof and to a 2x4 bolted to to a steel beam at the edges.

The profile is again sloped as in the diagram you shared, (but not curved), and the edge of our asphalt roof tiles is similarly protected To some extent by the 10” high steel-faced laminated peripheral beam.

Overall, rather similar in concept!

But I designed it only for myself and did no engineering calculations, at that time, 25 years ago!

It looks brand new today!

Hello. My daughter and son in law need to have their roof redone. A very small back-split bungalow. about 1500 sq. ft roof. They would like to go to a metal roof and in getting prices for a metal roof, they were told that it is better to leave the shingles on and install the metal roofing over the shingles. Plus they will save about $2500. not having to remove the shingles. I wouldn't mind hearing some opinions on this from the experts on the forum. Thanks,

Apparently, wind protection of the roof edge against wind is essential. Here a solution suggested for the Caribbean islands:

Jérôme, I would love to have a simple translation of these technical French terms and a description of how it works!

I built what I though was strong but the picture here takes into account wind protection that I haven’t addressed.

But by good fortune, no big gust of wind has managed to damage even a square cm of the roof!

It all depends on what lifetime warranty you expect. You can have a qualified co tractor put anything on and it will last with close to 100% probability for 5 years.

I prefer to strip and old roof of shingles and that way the attachment will be to structure you have seen and are certain of.

It’s absolutely necessary to get several competitive bids for both steel roofing as well as a replacement of shingles.

As it takes into account the quality of the basic home construction, only licensed and insured workers should be used and my opinion is worth nothing without being present and claiming on the roof and looking at the condition.

So tgsts what needs to be done.

….and now, in return for my input as modest as it might be, please add a photograph or two of workman to return us to Photogrwphy!

Thanks Jérôme,

You do explain well and succinctly.

For that function, I use wood bolted to steel with bolts welded to a steel I-beam so it seems mine is roughly as strong or even stronger!
