Mounting PV panels on flat roof

[fatbob]

Billericay, Thanks for the additional info on the ballast weights, I agree, I'm with you on the try it and see technique to prove the theoreticals are right.  At 16st I'm not far off your test loading capacity !

Sandra, you reply is very well timed, thanks for dipping on the thread, it seems as though you have gone through the same process I'm planning with both roof repairs and PV installation, will send you a PM.

Cheers,  Bob.
