Just give it a Name such as The Job Name or ? 1 Excel Template that FIGURES LENGTHS OF COMMON RAFTERS on a Gable Roof! 1 Excel Template that IS THE HOME ESTIMATING PROGRAM that will figure the Material Needs for 1 Single or Two Story Straight Home with Gable Roof! 1 Text Document that you may be reading right now! Even a First Time Builder shouldn't have any problems seeing how the spread sheet works! They are well commented and as simple as reading Dimensions From A Set Of Blue Prints and adding the data to the SS. BECAUSE SOME OF THE DIMENSIONS ARE CALCULATED DOWN AS MUCH AS A SQUARE INCH I RECOMMEND THE FOLLOWING!! I always recommend adding Ten Percent to the totals for items that you can't get a real accurate measurement on such as Basement Floors, Footers, etc!! You will also want to add a % to the lumber! I have never been on a job yet that you didn't unload some worthless lumber that had to be sent back!
