Roof Framing Calculator.

Joe | Posted in General Discussion on September 2, 2009 03:04am

Some of you guys know I’ve been working on an on-line roof framing calculator for awhile now ;-). Well I’ve made some more “improvements” to it and would appreciate any feedback you might have. Here is the link: http://www.josephfusco.org/Calculators/Simple%20Roof%20Calculator.html

Thanks.

    When I looked at the page you linked to, the left 1/2" or so of the calculator frame was chopped off....  From a glance at the page you are far more advanced that I on this web page stuff, but I have always found it best to look at the page on several different computers just to check that it shows up properly....

    BTW - I know you are a really smart guy, but for some reason I pictured you as having hair. :-)  BTW - I don't have much either - too much time "in the wind".... :-)

      Matt,Thanks for the feedback. You might need to increase your screen resolution a bit to see the whole calculator. It's setup to view on at least 17" screen with 1024 x768.As far as my hair goes, I just figured one to shave it off. The up side is it's easy to maintain ;-)

        19", 1024x768. 

        Sorry - I'm not changing my screen settings for just one web site.

        I used to have hair myslef.  It got so thin that I was blad when long hair kinda went out.  Now it's just a "#3 all over: Please" - when I get around to it.

          Matt,Didn't mean to imply you should. Just that that's the way it's setup. with your screen and resolution you should be able to see it just fine, maybe ;-). Anyway if you could maybe increase your res one click I'd like to know if that helps, if not, no problem.

            I upped the resolution a coupla notches to 1280x960.  Same thing.  Here is your clue:  The calculator is displayed properly when the page first comes up but then when the adds, etc on the left side of the page are filled in it clips the left side of the calculator frame.

            Afterwards, I set the resolution back to 1024x768 as those fonts and icons are too small for me to see comfortably. 

            Attached is a screen shot of what I'm seeing.

            Thanks Piffin,I test the page on a few "up to date" browsers, FIREFOX 3, IE8, FLOCK2, OPERA (great browser) and SAFARI 4. About 80% of the viewers to my site are on IE and I don't know why, although IE8 is a pretty good browser.

  2. jimAKAblue | Sep 02, 2009 05:29am | #8

    Joe, I looked at it and I think it's a wonderful tool. I'd probably use it myself if I was framing.

    I did try to change the "NO" to a "YeS" in the square fascia section but nothing happened. I probably had to do something else but since I was just testing, I really didn't try too hard. I can only remember doing one house, maybe two, in my thirty years of framing.

    I quickly browsed some of the terms. I notice you've included sections of "fixed ridge" heights and "fixed sloped" ridge heights. It kinda made me laugh thinking about how the two of us went round and round about that....maybe five or more years ago?

    Just a techical note about the use of the word "heel". First, the disclaimer: I know you can't include language for every tiny segment of the world, and I don't expect, nor ask for any changes in your work. With that said....in Michigan (Metro Detroit), we never used the term HAP or any variation of that. We always referred to the HAP as the "heel". We also never referred to the birdsmouth as a "heel cut". That just doesn't add up. We did, however, teach the young bucks to NOT CUT INTO THE HEEL! lol.

    My hats are off to you for putting up a wonderful resource. If I was framing, I'd insist that any apprentices that wanted me to teach them anything about roofs, would have to go to your site and thoroughly study and review all the terms and instructions there. You have put together a very interesting collection of information and the trade is better off for you effort.

    Milkbones to you!

      Joe | Sep 02, 2009 05:48am | #11

      Jim,Yes we did go round a few times ;-). Thanks for the feedback it helps make it a bit better. When you click "yes", the script updated the numbers immediately, you just needed to scroll down to see the change (I hope) ;-).I also think about updating the nomenclature as well to make it a bit more "region" friendly. There is a fairly large javascript running doing all the calculations, it's like a spreadsheet in away.

    I forgot to ask you.

    Is that a basic spreadsheet running in the background giving you the data?

  4. jimcco | Sep 02, 2009 09:37pm | #18

    Joe,

    My first run was for a reciently completed "L" floor plan with gable roofs with the wing of the house narrower so ridge was lower.

    What do you use to get jacks & valleys from that?

    What do use for dormers etc?

    1. User avater
      Joe | Sep 02, 2009 10:02pm | #19

      Jim,I wish this calculator was at the stage where you could enter your floor plan data and press a button ;-) But, it's not. You'd need to enter your roof as sections to get, well each section.Like entering the run and width of the first section of gable, get the calcs and then the next or "L" with the smaller run/width and then that those calcs.Whenever the calculator generates a gable it doesn't produce jacks because there are not suppose to be any ;-). The program assumes a "straight" run so, in your case with an ell you'd need a work around to get the valley and jacks that connect the ell.Give me a bit to think about that. . . And thanks for the input.

        Et al,

        Since we got into a good conversation on square cut rafter tails it prompt me

        to make yet another improvement to my Roof

        Framing Calculator. I've add the inch

        values for the conversion of the angles for the square cut tails. So now you'd

        be able to just use them to set your square to, to scribe the angles needed.

          Joe, Firefox, and the top left is cut off by the google ad box.It's cool and quick. Am I missing the 1x in the fascia drop down? All I see is 2x I've never even seen that for fascia.The hip/val members, are there any numbers for LVLs?I just saw an iPhone app construction master calculator, only it seemed even easier. Don't know if they've got a rafter deal, and those apps are pretty popular. May be a market for you?And, that piece doesn't help you one bit LOLhttp://www.tvwsolar.com

    I know you! Well, sort of. I had spent two days with a carpentry crew building dormer roofs. I liked the lead man's method of using a string and 2x4 for getting his angle and length for the rafters, so I looked it up on-line. I've already got your "Block and String" site saved on to my favorites. When I get a minute, I'll go over the new one.

    Keep up the good work! Guys like you help guys like me learn more about what they love to do!

    Joe,

    A whole lotta work went into that page!

    BUT!

    My resolution is 1024x768 and the calculator <Table> is still too narrow, even though it's width is set to 100%. See attachment.

    I think it's cuz' the google form table's two <TD>'s use a combined 656 px's. I think if you change the calc-table's width to a fixed width of maybe 500px  it should be OK.

    This will, of course put a scroll bar on bottom, but that ain't no thang.

      Hi Sam,Thanks for your feedback.The first thing I did when I clicked on your image was to go use the scroll bar lol.I designed the page at 1440p and at your res it's doing what it should be. The design center div collapses and the left and right div's remain constant to deal with different screen res. Sadly, I have to give the ads room because they help keep the lights on at my site. I'm working on. . . . a rework of that page but I don't see me implementing it very soon. I've got some more improvements to the calculator that I want to get in it and working first.The next big improvement will be to do different shaped roofs like ell's and U's and some different height stuff as well. Maybe by Xmas ;-)
