Not the answer to your question I know, but if this is DIY, then replacing a whole roof is notifiable to your local building control.. as they want to see that the insulation has been properly and adequately upgraded.

so you will need to factor in the cost of a minimum 100mm insulation as well if you are replacing the boards.

That site is scaremongering and out of date. It makes no mention of the 15 year payback, nor the fact that if a roof is repaired and not replaced, insulation is not required by the regs as laid down in Part L and its revisions. HIPS also no longer exist.
Yep hips out of date.
Yes no mention of repairs.. But original poster didn't refer to a repair they referred to replacement.
I can't remember now but it's something like if 75% of the roof is changed then the notification and insulation regulations apply.. Those do still stand as they are in the building regulations.
Those rules have not been dropped, due to government targets of reducing carbon emissions and eu commitments, which is why DIY window and door replacement is also notified, as a minimum rating of C is required
