replacing a facia advice please

[gillsboy2010]

Hello all,i need to replace my facias,i want to do the rear one myself as it looks more straight forward,iam adding some pics so that if anybody can point in the right direction as to what i should do.The rear facias are just wood boards fitted flush to the back of the proprty as you can see from pics,I have the main facia,and a smaller one to he right hand side,i have looked at a plastics supplier close to me and the materials are cheaps,just need to higher a scaffold tower,not sure if i should replace the original boards with new woodand then fit the plastic that goes over the top,or fir a solid barge board,but the boards that they sell dont seem to be as thick as the wood facias that are up there at the moment?any advice would be welcomed,thanks pete

ps
not sure where the pics are,i have done a album??

You can overclad retaining the existing facings if they are sound/free from rot.

there quite rotten mate,they got to come off,as its just a flush fit straight on to the existing joists do you think the solid plastic barge boards would be ok,or replace the wood with new timber board and over lap with the plastic covering? pete
