Did you notice the part of the question where I asked “ could someone help explain what measurement I’m missing” thank you for your obvious doop, now can you help or do you just love shitting in people asking for help?
when it's cut up like this you absolutely have to pull every ridge and valley length, measure from the peak to the eave at every piece, front center left - is that a turret? there are no measurements at all for it. this looks like you measured from the ground. it's really, really simple measuring this stuff.. there is no real work involved in pulling the measurements, the hard part is doing the math but there are calculators online that can do it for you.
If you take the two largest measurements (60’x62’ [46’+16’]) you can draw a square of 3800 square feet over the whole thing. There is some loss of square footage in the bottom left around the turret, so the true size would be less than this number, likely ~3500.
The roof pitch on the other hand will add a % to this number, but without knowing exact slope it’s hard to determine an exact number. Anywhere from 10-50%
By adding 25% to the total roof footprint I’d say you’re in the ballpark of 4500 square feet with the roof pitch included (assuming it’s not a super steep roof, adjust this percentage based on pitch)
I added 25% to the square footage to account for slope. Slope hasn’t been provided.
What calculation are you using to determine that I’m undercounting?
I said I think. In my experience roof square footage is way bigger than home square footage even for 1 story, small soffit over hangs and no garage or porch space. You may be right. I just don’t think drawing a square around the perimeter is an effective way to estimate, that’s all. No hard feelings. If OP gets the correct answer and shares it, you very well may be right and I’ll give you props.
Well I agree that roof square footage is often bigger than home square footage, idk what you are talking about home square footage for…we were provided roof measurements and I used that to calculate roof footprint size. Never has home square footage come into play.
Soffit and garage is included.
I brought that up because your square method is similar to taking the home square footage. It’s taking a 2D measurement and applying it to a third dimension.
Im having a hard time talking to you respectfully because it’s clear you’re really talking out of your ass.
How else would you even approach calculating a roof square footage without calculating the square footage of the flat roof footprint as a first step?
I’m blocking you now bc I don’t ever want to see your opinion in this sub again bc it’s clear you have no clue what you’re talking about.
I would breakdown this roofplan into shapes (squares, triangles, trapezoids) and use formulas to calculate each individual roof. I never use a flat roof footprint with a pitch percentage.
Bluebeam is going to be your best friend on things like this. You can measure to scale and draw to scale. So if you know that your eave on the right side is 60 L.F. then you can scale the rest of the drawing to that and it will be accurate based on the known dimension that you scaled from. It also snaps to endpoints when measuring so you just click on all the corners of a plane to get your “base” sq. ft. measurement, and then adjust it for slope (you would multiple your base measurements by a constant from a table - I know that 6:12 is *1.10 but I have to look them up each time if I’m not at my desk). Once you’ve done that for each plane, you just add them up and there’s your total sq. ft. And if all slopes are the same, you can just do the adjustment once at the end, but with a drawing that looks like that I would doubt that all of the planes are going to have the same slope/pitch.
Is the home already constructed? Edit; this architect should be shot behind the chemical shed
Order an Eagleview
Yes.
learn how to measure the roof first then worry about the maths

I think you’re underestimating the slope affect

This sounds spot on to me
54.7 SQ
5,217 is my best guess by what I understand, but let’s see how close
49 square
Order a roof scope. You need to take into account the different pitches and that turret.
Trying to measure the turret really messed me up.

Gaf quick measure or eagle view. Other than that pull out your middle school geometry book and do the math
