How do I find the information that DI requires for the Rental Order Form?
DI requires information during the order process so we can prepare your Roof Seamer for your job!
ROOF PANEL INFORMATION is required so we know what profile that you are working with and who made it. DI works with just about all panel manufacturers and is familiar with all roof panels that are available on the market today. However, to correctly setup your Roof Seamer, we need to know the following information:
Panel Manufacturer: We are looking for the name of the company that produces the roof panel. (Example: ATAS International, McElroy Metal, Firestone Building Products, etc.*)
Panel Name: Roof Panel Manufacturers give unique names to all of their products to set them apart from their competition. We are looking for the name that they have given the specific panel that you are working with. Keep in mind that you may have multiple types of panels on one job.
Roof Finish: There are many types of finishes available for roof panels today. We are wanting to know if your roof panel is painted or not. This is specifically designed so we will know what type of tooling to equip your roof seamer with. If a roof seamer's tooling has ever been ran on a panel with a galvaume finish, pitting can occur from the galvalume flakes embedding into the tooling. If the same tooling is ever ran on a painted panel, it can easily damage the paint finish. For this reason, DI segregates all of our tooling so if a roller has ever been used on a galvaume panel, it will NEVER be ran on a painted panel again.
Seam Height: Simply measure from the base (pan) of the panel to the top of the unseamed rib. This dimension is usually measured in inches such as 1.5" or 2". Commonly, if you are working with a trapezoidal style panel, the seam height will always be 3".
*-Although we work with all roof panel manufacturer's products, DI does not claim official affiliation with any company mentioned here.
GAUGE of the material that you are working with is critical to the setup of your roof seamer. When filling out the order form, all materials are assumed to be steel, unless you tell us otherwise. D.I. can work with many materials including steel, copper, aluminum, stainless steel and zinc. For steel panels, you may measure the gauge using a set of calipers. Use the reference chart below to determine your material's gauge.

SQUARE FOOTAGE (Sq. Ft.) is required to let us know how big your project is. This number does not have to be exact, but it needs to accurately represent the scope of your job. To determine the total square footage of a project, simply multiply the length by the width of the total roof. In the example below, the roof is 240' X 80'. When multiplied together, it shows us that the total square footage is 19,200 sq.ft.
To calculate the total square footage for YOUR project, please use one of the calculators below:
Please note: For your convenience, this calculation has been rounded up slightly.
Helpful Information: If an area is rectangular, the method is simple: Round each measurement up to the nearest foot or half foot. Then, multiply length times width. For triangular and circular areas, the calculation is typically more complicated.
To figure the area of a circle, multiply 3.14 (pi) times the square of the radius (the distance from the center of the circle to the circle's outside edge or circumference). To calculate the area of a right triangle (that is, a triangle with one 90-degree angle), multiply 0.5 times the base (the short line attached to the right angle) times the height (the long line attached to the right angle). Or, just fill in the blanks above. If an area is irregularly shaped, divide it up into rectangles and right triangles as precisely as possible. Figure the area of each rectangle or triangle, and add up all the figures.
SEAM HEIGHT is determined by measuring the height of the female leg of the roof panel. You should measure from the base of the panel (pan) to the top of the leg. This measurments does not have to be exact. Commonly, roll formers will form the dimension differently from panel-to-panel. The most common seam hieghts are 1", 1.5", 2" and 3".
ROOF PITCH is measured by "rise over run". This is a common civil engineering term meaning the "slope" or "pitch" of a roof. You can measure "rise over run" by taking a level and placing it horizontally from any point on the slope of a roof. Take a scale of your choice and allow it to hang straight down from the 12" mark (you can use a plumb-bob for reference if necessary). The distance from the roof surface to the level is your "rise". As a standard, "run" is always 12" when dealing with roofing. Therefore, your roof pitch will always be x/12 with the x representing your "rise" number.
RADIUS is measured by pretending that your curved roof panel makes a complete circle. The distance from the center of that circle to the panel, is the radius. In the diagram, "R" stands for the radius of the panel. D.I. has special machines that can seam a panel with only a slight curve to it down to a 48" radius!
PERIMETER CLIPS are used in various locations on a roof that may be affected by high winds. These are usually seen in the plain states or in coastal regions of the U.S. The decision to use perimeter clips is usually decided between the building manufacturer and your designer or architect as dictated by local building codes. The only difference between one of your regular clips and a perimeter clip is the size and UL ratings. A perimeter clip is utilized, as the name implies, around the perimeter of the roof to give it added strength. These are not used in the "field" of the roof.
END LAPS refers to the location where a roof panel may overlap another roof panel. This information is required so that we may equip your roof seamer to deal with sudden introductions of thicker materials. Any time that the machine is running along a rib and is suddenly given twice the amount of material to form as it was a second before, it can damage the machine if it is not prepared and adjusted for it when it leaves the factory and comes to you.
