I forgot to mention that you need to add in the eaves and other overhangs.
It's not just about the square footage of the building.

Well I did pay attention in class and found geometry to be fun and
made a good grade.

I tried to solve this by using a^2 = (B^2)+(C^2) to find the long
leg. The answer didn't seem right so I am looking to check it.

From the calculator above I made a mistake. Some where.

That will depend on how the roof is built. One plane sloping from one
side to other other will be less than a hip design. If you have gables
on one or both ends that will change a little too.

5/12 is a particularly convenient slope actually. It's one of the famous
Pythagorean Triples. Sides of 5, 12 and 13 make a right triangle. So if
your horizontal and vertical measurements were actually 12 and 5, the
"hypotenuse" length would be 13. If it's something else, just multiply
the horizontal measurement by 13/12.

Your equation should work. Use the numbers above as an example 13^2
(169) = 5^2 (25) + 12^2 (144)

I wonder if you added up the squares of the two legs but forgot to take
the square root of the result.

Don't forget that Pythagorus requires a right triangle.

Take the triangle formed by the roof (22.5/22.5/135 degrees),
bisect into two right-triangles, then use trig to calculate
the hypotenuse length, since you know the length of the
adjacent side (1/2 the length of the long side of the
original triangle - the long side is opposite the 135 degree
angle).

cos(90) = adjacent/hypotenuse

hypotenuse = cos(90)/adjacent

area = 2 x (hypotenuse x length of roof).

Shooting pool ain't just about geometry. Left spin, right spin, back spin, over the top spin, force of the shot, hard kiss, soft kiss, it all adds up to making the ball go everywhere but in the pocket. Doubt old Pythagoras ever shot a game of pool in his life.

Sometimes that is literally and by far the fastest way to get that
information!

Puckdropper

Hmmmm....

Feeling a little old fashioned here. I do a lot of roofing within my contracting 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 probably 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 chimney,and pick up any considerations for any other structural features.

You can check your skylights, measure valleys for sheet metal, count your pipe jacks and make sure any other sheet metal features and venting (think square vent hood caps) are still serviceable as well as measure for storm caps, etc. Also, the number of valleys (and their sizes) as well as different features will require that a factor is added for the shingles needed to properly roof/seal the valleys. You can also look for damage to the existing 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.

Thanks, Sonny. I do have the Windows character map, just too lazy to use it
most of the time.

About the only time I use it is if I'm writing to someone in Spanish. The
special characters can make a very big difference there. For example, if I
write...

Espero que tengas un feliz año nuevo

I've said, "I hope you may have a happy new year" but if I write...

Espero que tengas un feliz ano nuevo

I've said, "I hope you may have a happy new anus"

Sorry, that should have been "four semesters".

I think it's less about using the skills you learned in high school and more about

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 ability to learn what you need know to accomplish what you are trying to do
Is more important than any given subject matter.

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).

13/12 works because it is an approximation of the cosine of a 22.5
degree angle (which is the angle for a 5/12 roof). Saves roofers
from requiring trig functions on their calculator.

My previous house had a 15:12 pitch on the main house (12:12 on the

pitches but found that it was code for the area. No idea why. My

That's unnecessarily complicated. It's a 5/12 roof pitch therefore the
roof area is 13/12 the base area. Simple!

Explain that in detail again, if you don't mind.


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.

It takes two these days.

Carlos gets on the roof and measures.

I write them down and do the math.

Thought I'd never get to this point ...

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).

http://www.jstor.org/stable/659023

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. ; )

13/12 works because it is an approximation of the cosine of a 22.5
degree angle (which is the angle for a 5/12 roof). Saves roofers
from requiring trig functions on their calculator.

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?

Ouch! Sound like you were living right!

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 smashed 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 is 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 for architectural purposes, we never see those super high slope roofs.

Nasty business, those.

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. ;-)

How do I figure the area of the roof?

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.
