If nails into wooden purlins, cut underneath with reciprocating saw,

We need to replace a roof on a 70s building sometime in the future. It currently has angle iron purlins with J bolts hooked to them. What’s the best thing to do to replace this, I’m guessing that tech screws won’t penetrate the angle purlins. We could bolt on timber purlins and screw into them or is there an easier way?

You can still get hook bolts. I have the same job to do next summer and was advised to used Tek screws, they'll certainly be less fiddly.

If the angle is meaty then be prepared for some graft on the drill. Those tek screws will do it and do it easy if you can get enough push behind them but without enough pressure you're in for a long job.

It’s a 100ft by 80ft roof, hundreds of screws do you need 2 people with J bolts to put them from the underside out?

You could use a sharp drill bit and pilot hole then tex screws

Teks will penetrate angle iron no bother .

Use self drilling tek screws for fibre cement. Make sure you get ones for steel not the ones for cold rolled Z purlins as those will burn out before they get through angle

Tek screws, get the heavy duty ones with the fine thread. Done one myself with them, not that bad a job if you can get enough pressure on the drill.

Left the 120x60 with rsj purlins to the professionals though. Must have been a savage job to do with tek screws.
