I think it's less about using the skills you learned in high school and more about learning, period.
The ability to learn what you need know to accomplish what you are trying to do Is more important than any given subject matter.

Hmmmm....
Feeling a little old fashioned here. I do a lot of roofing within my contr acting business, and I get on the roof and measure it. If it is a shotgun roof, no need.
But if it has a gable or two that intersect the main roof (which are probab ly at a different slope) you will pick up the exact measurements you need. This will also allow you to consider large "saddles" or diverters behind c himney,and pick up any considerations for any other structural features.
You can check your skylights, measure valleys for sheet metal, count your p ipe jacks and make sure any other sheet metal features and venting (think s quare vent hood caps) are still serviceable as well as measure for storm ca ps, etc. Also, the number of valleys (and their sizes) as well as differen t features will require that a factor is added for the shingles needed to p roperly roof/seal the valleys. You can also look for damage to the existin g surface to make sure that unseen leaks that haven't presented inside the house have not caused decking or structure damage.
Yep... it's on the roof for me.

Argh. hypotenuse = cos(90) x adjacent
It takes two these days.
Carlos gets on the roof and measures. Calls the numbers down to me. I write them down and do the math.
Thought I'd never get to this point ... ;)
Sorry, that should have been "four semesters".
I don't agree. Secondary school should be about learning things that you will need to become a productive citizen. That includes learning how to learn but it also includes at least "business" math, some history and civics. Unfortunately it's now more about indoctrination.
I didn't have any "calculus" in high school, though. We were taught all of the foundations for it but not the grind. ;-)
The foundations are pretty important. Without arithmetic (and I'll include at least beginning algebra) you're toast in any technical field (everything is now). Without learning some sense of history and civics, we're doomed (they don't and we are - hopefully I won't see it but I'm not so sure).
That's unnecessarily complicated. It's a 5/12 roof pitch therefore the roof area is 13/12 the base area. Simple! Graham
Explain that in detail again, if you don't mind.
I don't get on them anymore unless they are no more than 7/12. I won't get on a metal roof unless it is 5/12 or less without some safety gear. I hav e alternative ways of measuring a high slope roof from taking detailed phot os (standard shingle is 36" wide with a 5" reveal), but can also include ha ving Hector (if needed) measure them for me if it is something nasty. If i t is one of those gawdawful Tudor styles with the 12/12 feature roofs on to p of high slope hips, I pass.
I slid off a 6.5/12 sheet metal roof about 10 years ago and went all the wa y to the ground after sliding about 40 feet. I didn't break anything, but thought I was killed. I hit like a bag of wet sand, and stayed in place fo r about 5 minutes after impact to make sure I was OK. Lesson learned?
Don't bounce like I used to. That falls in line with a lot of other lessons I am learning along the way like the fewer 12 hour days the better, don't eat too much at lunch or I will be sleepy all afternoon, not too much hot s auce when going back out to work on the job followed by keeping a jumbo bot tle of antacids in the truck, bring my glasses to the job, stand on a ladde r not a paint can, don't overreach from the ladder, make a list for the day 's goals so I don't forget things to do, don't stop for a late lunch as I m ight not go back to work... how things change.

My previous house had a 15:12 pitch on the main house (12:12 on the garage). Might just as well be vertical. I was surprised at the high pitches but found that it was code for the area. No idea why. My current house is probably at least 12:12 but I've never bothered to measure.
Ouch! Sound like you were living right!
The slope length on a 5/12 ratio roof is 13 (5x5 + 12x12 = 13x13). In other words the roof distance from crest to wall is 13/12 (1.0833) the size of the floor measurement So if the floor area of the garage plus overhang is LxW, the roof area is LxW x 1.0833 for a 5/12 roof pitch.
I was watching ATOH a few weeks ago. A (young) chimney guy was putting a cap on what appeared to be a double chimney, so you know the cap was fairly wide.
It was an older 2 story house with full attic, so he was pretty high above the street. He had a step ladder leaning up against the peak-side of the chimney, i.e. the narrow side of the chimney in this picture.
He was not secured by any straps. He lifted the cap over his head and simply walked up the step ladder, plopping the cap on top of the chimney. One gust of wind as he was walking up the step ladder and he would have been on the street.
I almost crapped my pants just watching him.
Since I posted I pictures last year, I didn't mention it this year, but I made my 2nd pilgrimage to Colonial Williamsburg a few weeks ago. The antique furniture in the museum is starting to feel like old friends and I spent enjoyable time in the cabinetmakers shop. Recommended, if you're on the eastern side of the country. This time, my wife brought plenty of apples for some of the horses (the ones that weren't currently working).
But back to history, after my visit above, I became more curious about the related history prior to the mid 18th century. Wikipedia contained the following reference which I found interesting (Note: I didn't finish it yet).
In a nutshell, it describes some of the dynamics between the new "settlers" and the indigenous (Indian) population. Wikipedia, of course, contains a lot of historical facts in bite-size pieces. I owe credit Williamsburg for fostering my interest (making me a slightly more-informed individual). I still have a lot of catching up to do, I suppose. ; )

The angle of a 5/12 roof is arctan (5/12) = 22.62 degrees; 13/12 is *exact* (as has been pointed out by several others in this thread, 5-12-13 is a Pythagorean triple).
Perhaps you meant to say that a 5/12 pitch approximates a 22.5 degree angle?
Don't I know it! I was pretty sore from it, but I have one guy that I know that broke his back when he fell off a lower eave roof and another that sm ashed his shoulder to the point if being in a body cast to hold it in place . Dumb luck, nothing else.
I am wondering if the reason you have such a tremendously high slope roof i s because of deed restrictions (trying to maintain some continuity of style in your area) or if you have a lot of snow and ice? Even for snow and ice the requirements are much lower, say 8/12 or so.
We have very little to no snow, rarely any ice on roofs, so unless it is fo r architectural purposes, we never see those super high slope roofs.
Nasty business, those.
Robert
Must be. No snow or ice to worry about in AL or GA. ;-)
I thought it really weird since wind can be a problem (hurricanes). I never expected to see high pitches in the South but it's the norm.
Well, they shingle walls, too. ;-)
show what you tried so far
The past few years the roofing contractor I use uses these guys, and presents their bid based on satellite imagery/Aerial Measurement Technology:
When I meet them onsite to discuss material, style, etc, they're already ahead of game, just have to plug in the numbers.
