how do i erect a roof?

simple answer?u cant,even the description would run into several a4 pages.i cant even think of a single book that covers this in all but either the most basic or extremly complicated terms. no offence but what ur asking is the equivalent asking an apprentice to make a roof and then expecting it to be done when u get back.however if u are determined then THE MODERN PRACTICAL CARPENTER.by GEORGE ELLIS is as good a place to start as any.dont be put of by publish date .
