Repairs to shared roof

there was a report i think in il centro... regarding people with second homes in the L'aquila area... whats is important is that the house is in one of the designated primary damaged comunes... the list used to be 49 or so but that might have changed... in that area even second home owners will be entitled to a sum of 80,000 if there home has suffered considerable damage and lesser sums assigned depending on each case... the first step even if you are not in the primary area is to get your friend or his neighbour to report the damage to the comune and have a technician visit and asses damage and register it ... in that case whatever is done will then have a record of damage and the government is giving people the option to use there own contractors ... so its not a question of waiting fro the comune to do the work... sorry its not a clear reply... the other point that might make the neighbour a bit worried is that if they say the place is too unstable ...he might not be allowed back in the house...the comune could stick a prohibition notice on it...anyway il centro has a good search system online... maybe try and find the article i read that way...as trying to wade through all the earthquake news would be a bit muchthe other thing is i posted something the other day on the other place...its to do with public administration help...http://www.lineaamica.it/its a new site...well to me anyway but it will be worth a look as its covering earthquake issues too...as for responsibilities over roofs this is often shared out on a divided property... but that would have to be answered after reading the property details... ie the final act and if that contains any conditions about shared responsibility for the roof and or maintenance of the buildingsorry not a clear reply ... but maybe a place to start looking
