If the roof is not a very simple roof, you have to measure each roof section individually and do the geometry for each roof section. Then add up all the sections for a total number of squares.

If the print doesn't have a roof plan, I suggest creating your own by examing the floor plans and elevations.

BTW I have 6/12 @ 1.11 and 7/12 @ 1.16

The roof is is a simple 4 sided hip, the print does have a roof plan scale is 3/16= 1' , I'm alittle confused because of the elevation plan is 1/4 = 1' so therefore if i scale on the roof plan from the eve to ridge i come up with 30' and on the elevation plan from the eve to the ridge is 15'. SO i want to know if iam correct on the 67' x 80' =5360 x pitch 6/12 =5949.60 around 60 squares correct. THats the total number of squares he needs for the roof then right then add some more squares for the ridge cap correct, overall he is building a 5000 sf building.

So in other words do i just add 67'x 80 = sf or do i mutilply it twice 67'x 80' = 5360 x 2.thanxherm said:The roof is is a simple 4 sided hip, the print does have a roof plan scale is 3/16= 1' , I'm alittle confused because of the elevation plan is 1/4 = 1' so therefore if i scale on the roof plan from the eve to ridge i come up with 30' and on the elevation plan from the eve to the ridge is 15'.

If you do it the hard way you will be 100% correct each and every time.

so i guess i'll just go off the roof plan in the blueprint then once again thanx alot for the info it is greatly appreciated.Grumpy said:

Take the width x length x pitch factor. Add 5%, give or take, for the waste. Ignore the dimensions on the elevations. What throws you off is the elevation is showing the difference in height between the eave and the ridge. Just use the square footage. I look at several prints a day.
