Why are roofs on new builds made out of wood and not steel?

    The issue is that have to be detailed properly, and installed properly, neither of which is particularly strong in Ireland. Maybe it's getting better, but in the past they weren;t even mentioning building design/architectural courses. Instead it was all Homebond guide.

    I'd prefer my house construction to be "better" for it's useful life rather than during its construction.

    Timber is good for nothing here in my own opinion it rots far too easily and Ireland has one of the worst miserable climates you can imagine for timber. The softwood crap that they plant here isn't worth a damn, fences and patio decking done during the boom have mainly rotted away now. Farmers on an never-ending journey of fencing with softwood stakes. Oak; the Brown oak is the only wood of any use I would use in structural timber because I am thinking longevity. More Concrete builds and Steel roofs should be encouraged I would say. Irish White Deal Spruce would be perfect for places like Dubai or Saudi Arabia where they are bone dry all the time but not Ireland.

    There is a world of difference between a fence post and a rafter. They're completely different applications.

    In a modern externally insulated roof the structural timbers don't even get cold, let alone wet.

    None of the issues I mentioned were construction benefits. That's the contractors area of concern.

    Speed, might seem like a construction issue. But it's actually a budget one. Building more faster reduces cost for the client/owner.
    Services benefit should be a no brainer. Much easier to reticulate increased amount of services that you find in commercial jobs.
    Also much easier to dismount and reconfigure over time. Which has obvious commercial benefits for a client.

    On the scale of a one off house, might not be of interest. As I said, on big jobs. Even the biggest house, is a very small job.

    If your rafters are getting wet you should confirm that you have them on the right side of the tiles! :D

    Timber is good for nothing? It's great if maintained. It rains more in the Pacific Northwest and they build their homes with timber frames and wooden facades. No brickwork there and those houses are fine.

    This is the classic outdated, old school response with not much thinking behind it.... although i agree the crap they plant is useless and very damaging environmentally
