Flat roof advice
Andy Warrant 30/06/2026 - 7.59 AM
Hi. I have managed to now get the joists on fixed to the timber wall plate but not every joist is bang on level either due to natural defects in the timber or the wall plate not sitting 100% level due to me not having all the tools available and first time trying a diy flat roof. Will this cause me untold problems later down the line or can I make sure the firing strips are fitted with packers where recess before installing the osb? I’m wondering how much more money I waste before I give in and pass to an expert?
Are you a tradesperson and able to answer this question?

Once you fit the furrings to offset the roof you would be ok

These days your lucky if any timber is level tbf , but as long as your not talking "major " height differences, the roof will still run towards your drip edge because of the fairings, but keep in mind that the underside of the joists is the ceiling, hope that helped
