    I have a cubicle house with the old style curved roof on it. I want to increase the ventilation by raising a few of the central sheets. Has anyone done this and what is the best way to go about it?
    Would a Cherrypicker (raised platform) from outside be the best option?
    I would like to do it myself, if I can but want to do it safely.

    Raised the center sheet on round roof shed here, took off sheet, 3*3 timber under each end. Sure it was done from the top, so long ago can't remember, lean to on eiher side.

    Done here with two sheets on each span, they are just a different curve than the others.

    Ya ,VERY STRAIGHT FORWARD. Done all the work from the top of the roof. Have all your materials in place so as not to be up and down like a yoyo! Treat your 5*3 timbers ....easily forgotten. Enjoy

    Ok, you lift off the center sheets, but the top of the lower side sheets are there over the timber purlins underneath. Did ye just nail down the new timber on top of the old side sheets?

    What we did is to raise the sheeting up maybe 300mm( long time since it was done) fixing an angle iron bracket to existing purlins by 2 no. bolts and fixing the new timber on top in the same manner as above. We bought new sheets that were longer than we took up and an extra sheet to extend an overlap over the opening. This allowed for increase air movement and avoid driving rain which we have alot in our yard.:(

    That's how we did it too using 2 inch angle. Put a stick across on top of the angle and buy a new bigger sheet that will extend over the gap left by the sheet you took out. Helps keep rain out. Id say we raised ours about a foot but that would be up to yourself.
