Welcome to Framing Calc Roof Edition

Framing Calc Roof (FCR) has several methods for configuring or calculating your roof. One of which is the "Library Method". Another quicker method is its "Quick Solver". These are the two primary methods, but there are other less involved calculators like the pitch calculator and others.

Library Roof Configuration Method:

Please note: All the images below are actual screen shots from Framing Calc Roof Edition. The image quality has been for faster web page loading purposes.

With this method the builder may select a particular style or floor plan detail from a library of plans. The various plans are versatile enough to cover practically every roof foot print conceivable, though again, these are the basics, we're certain any architect or home owner could come up with roofs that do not fall into one of the categories 100%. The library that will be released in our first version may be upgraded by plugging in more roof conditions as we develop them. Thus far the roof plans in the library are:

1) Straight Roof Condition:A straight roof is simply a rectangle. Four sides, with one span and two runs. Each run may have a different pitch, and different bearing wall height. The builder basically just fills in the blanks, and enters dimensions in the lettered variables, and elevations in the numbered ones. The program acts like a solver in that as you enter data into the appropriate boxes, the program will fill in the ones it can calculate for you. Another option available is the ability to adjust the amount of bearing of the rafters seat cut on the bearing wall. Notice the two details below, which are (as all of the images below are) screen shots of the actual program. Changing the seat cut size changes the wall height, and Framing Calc Roof Edition can make it any amount you like.

2) T Roof Condition: Any combination of structures having a shape like a "T", or three gables with a pair of valleys. In a T shaped structure there are 10 variable building dimensions, and 6 variable elevation heights. Since there are two techniques for building the area where the two rectangles merge, they are included in the variables. The builder may select true valley beam construction or California Fill construction which is when one roof is built on top of another and there are no valley beams.

(True Valley Condition) (California Fill Condition)

3) L Roof Condition: Any combination of structures having a shape like an "L". Typical Hip / Valley combinations.

4) Additional Roof Conditions include: Z Structures, H Structures, and a combination of a "T" Structure, and an "L" Structure. All of which (excepting the L and Z structures) have the option of going with True Valleys, or California Fill methods. All the user need do to customize any of these templates is change the lettered values to suite, and the numbered values. The letters (A,B,C,D, etc) represent dimension, whereas the numbers represent elevation/wall heights. The ridges can be off center, and the pitches on each side of the ridge may be different as well. It is even capable of creating a "Bastard" hip or valley, where the pitch on either side of the hip or valley differs. The screen shot in the second row, first screen shot, shows two pitches in a single span in a T structure condition. 12/12 pitch on the left and a 5/12 on the right. Framing Calc Roof Edition can depict virtually any roof condition. The screen shot to its right, with the rafters removed, shows a "Bastard Hip and Valley" in an "L" Roof Structure.

Quick Solver Roof Calculation Method:

This is a very simple and quick technique for determining your roofs various components dimensions, and for developing a cutlist and material list. The builder simply enters variables into the appropriate boxes, and when the program has enough information, it begins to complete the remaining boxes for him. For example if the builder wants to determine the height of his ridge, but only knows the elevation of the lower bearing wall, the run, and the pitch. He enters the information that he has and by the time he gets to the third entry the program has already filled in the fourth, fifth, sixth, and so on. The Quick Solver will solve for all your roof components, including hips, valleys, jacks, commons, and it can take into account overhangs, beam sizes, etc. A great way to go when you are in a hurry, or the library does not have your particular roof design.

Misc. Software Tools:

Included in the program are various tools for quick information access.

1) Increment Converter: A conversion tool which converts virtually any unit of measurement to virtually any other unit of measurement. And using any amount for the value.

2) Pitch Calc: A quick angle finder for any pitch you can imagine.

Reports:

Now that all the calculating is complete, the program can produce and print out various customized reports. Including but not limited to:

1) Complete Material List from which the builder can use to fax to his lumber suppliers for bidding purposes. Materials included in the list are quantity, cost, and spec of the sheathing. Quantity, size, cost, and spec of the common rafters, hips, valleys, jacks etc. Quantity, size, cost, and spec of the blocking and sub fascia materials. Quantity, size, cost, and spec of the fascia.

2) Complete Cut List from which the builder can hand over to his forman or cut man. Cut List includes quantity, and exact lengths of Common Rafters, hips, valleys, jacks, and blocking etc.

3) Complete Cost Report , sheets, and square footage of materials required. Along with the user entered price per unit, and a total price for each material, sales tax, and grand total for the entire roof project.

Couple Framing Calc Roof Edition up with its little brother Framing Calc Wall Edition, and you would never have dreamed that estimating the cost of a project could be so easy. These programs pay for themselves the very first time they are used.
