1. this one is a retro fit.
    we lathed it out with 1x4s over the shingles And insulation, fastened into underlying framing 20″apart

  2. I am so glad I am not a roofer, I don’t think I’m smart enough to figure out all thoes cuts and folds. That is a beautiful job, I am so glad that one fella is a far better roofer than a camera man.

  3. oh I just love crap like this. those guys are obviously well salted pro’s. I wasn’t that familiar with metal roofing systems. 1) I didn’t know it was so complicated to get that professional,finished look 2) I didn’t know that if you listened carefully and payed attention you could learn so much. maybe not so much to give it a go like I’m going to ,but enough to enjoy sitting and watching it again. Huge tremendous Qaalpla’s to America’s backbone. The tradesmen. subbed. thanks for the educational fun guys.

  4. I am curious on where you bought your sheet metal edge folding tool? I would like to buy one and try it out. I looked and cannot find that exact one you use in your video

  5. Nice roofing but i just want to point out the problem i’m currently facing. From the research i’ve been doing it looks like an air gap between the insolation and the roof is necessary, to both stop thermal bridging from the insulation to the tin (heat loss) and also to stop radiant heat transferring from the underside of the tin into the insulation (heat gain in the summer). However it is also recommended that tin roofing is fixed to a flat board, if your going to walk on it it is defiantly a good idea IMO. Solutions i have seen are either to add another layer of baton and then another deck (more osb) so the air gap is under the final layer of deck and the insulation is beneath that or to use 1×4 baton perhaps diagonally or horizontally with notching under the baton to provide a vertical airflow.
    If heat is a real problem then it looks like you should consider an extra later with foil and another air gap.
    There is no simple solution, all solutions are expensive but to avoid general condensation, ridge rot or ice dams some of the above techniques should be applied.
    It depends if the loft space is conditioned (house tempreture) or if it is ventalated and insulated above the top floor ceilings. I have been trying to get my head around this the last few days, there are also underlayments air tight barriers and breathable membranes to consider. It’s no wonder so many people are doing it wrong especially when you combine all of that with cost, time and the clients budget.
    Our house needs a new roof but we have large overhangs and we live at 1000M so climate is very variable. Now just to decide how to do this, i’m still lost!
