Two men will frame and put in place 600 linear feet of 2 x 6 inch or 2 x 8 inch rafters in one day on a plain gabled roof; in a hip roof, including framing for deck, when there is one, 250 feet, running measure, is a good day's work for one man. Does one want to use a professional, someone who already knows how to install torch down roofing, or should one try to do it themselves. Shakes are either hand-split or resawn (split on the side) or tapersawn (sawn on both sides) and shingles are sawn on both the sides. Here is my website: miami roof repair
