Why D.I.?

Green D.I.


Our Roof Seamers and other products are constructed from high quality aircraft aluminum and are incredibly durable, reinforced by anodization. We currently have roof seaming machines that have been in use for over 20 years and are still going strong. Our products are proving themselves to exceed any known standards of excellence in our field. The products that we manufacture help us continue to be committed to a cleaner environment by engineering parts and machines that are long lasting and durable, therefore creating less waste. Every metal or aluminum item that is used by our facility is recycled.

D.I. Roof Seamers is committed to leading the industry in minimizing the impact of its activities on the environment. The key points of its strategy to achieve this are:

  • Minimize waste by evaluating operations and ensuring they are as efficient as possible.
  • Minimize toxic emissions through the selection and use of its fleet and the source of its power requirement.
  • Actively promote recycling both internally and amongst our customers and suppliers.
  • Source and promote a product range to minimize the environmental impact of both production and distribution.
  • Meet or exceed all the environmental legislation that relates to the Company.
  • Use an accredited program to offset the greenhouse gas emissions generated by our activities.

Quality Control Process


Our in-depth QC Processes set us apart from any other Roof Seamer manufacturer. We don't just pull a dusty roof seamer off of the shelf from the last job and send it to you. Every time you receive a D.I. Roof Seamer, it will look and perform like new.

When you place your order, D.I. takes a machine that has been broken down to its bare parts, cleaned, maintenance and re-assembled. We use custom tooling specifically designed to work with your roof panel and clip combination and that has been approved by the roof panel manufacturer. Then, we simulate your project's environment by re-creating the substrate and roof pitch that you specify during ordering in our test facility. This isn't something that we do for special customers; this is something that we do EVERY TIME a Roof Seamer goes out to a customer.

From here, the exact roof panel and clip combination that you are working with is applied to the test roof. The Roof Seamer that you will be working with is used to create an exceptional seam on the roof. From here, we know that the machine will perform on your jobsite and it is sent to Final Inspection. The seam that was produced doesn't get discarded. A sample is removed from the core of the seam, inspected, tagged and cataloged. We will keep a sample of your seam thorough the duration of your project. This is for easier reference for one of our TSR's in case a problem occurs on the jobsite.

At Final Inspection, every Roof Seamer is gone over with intricate detail. The smallest flaw in a piece of tooling or a loose sprocket will cause the machine to be rejected and the entire process will have to begin again. The entire contents of your order is put together and photographed. This includes the Roof Seamer, any Hand Crimpers, a field tool kit, your user's manual, the Roof Seamer Certification (to be kept of the jobsite) and an extra copy of your paperwork.

We go the extra mile before your Roof Seamer leaves our facility on its way to you. This is the reason we require 48 hours from the time the order is placed before your machine ships out. When you can, always order a Roof Seamer in advance! Just let us know when you need the machine on your site and we'll take care of the rest!

D.I. Employee Training


D.I. uses a very intense training program for our employees. Since we are the only company that does what we do, it is very difficult for a person to prepare for or actually get a job at D.I.

On your first day on the job, you immediately begin training for your Associate I Certification. This process will take as long as 30 days to actually complete and make you eligible to advance through D.I.'s training program. If you fail to meet the requirements during the Associate I training program, your journey with D.I. will most likely come to an end.

The Associate II Certification will take an additional 30 days of training to complete. From there, you graduate to the Technician Program. The level of Technician is a 90 day window to prepare you for the next evolution of training. This is a very intensive couple of months in which you are presented with endless scenarios and real-world situations that a Certified Lead Technician can face every day. Lead Technician is a very difficult position to obtain. This person is in charge of every Roof Seamer that leaves the building going directly to a customer. They can easily identify and correct modulation and set-up problems without slowing production. As with each level of training a lengthy written exam must be passed, but with Lead Technician there is a grueling practical exam that can last for hours on end. The Journey from your first day on the job to Lead Technician can be accomplished in as little as 1 year and 6 months, but usually takes much longer.

When you deal with most businesses today, a Customer Service Representative is an entry level position that is given to a person that is lucky to know how to answer the telephone. When you speak with a CSR at D.I., you are speaking with a highly trained individual that has accomplished the level of Lead Technician in addition to a one year apprenticeship program. A CSR will be able to help you with ANY problem or question that you may have.

A Technical Service Representative is similar to a CSR, but with a different discipline in training. This TSR Program is also a one-year venture beyond the level of Lead Technician and encompasses a 'field' approach to problems. A TSR is the person that shows up when a problem should occur on your roof. TSR training is a very extensive program that includes many jobsite visits and problem solving situations that occur on a roof 100' in the air on a 7/12 pitch. This program is not for everyone, but the elite people that have accomplished this position are ready to help you in any way that you will need it.

As you can see, a D.I. employee is not something that you just casually introduce yourself as. A D.I. employee is a competent team member that is able to serve you. With training programs that can take almost 4 years to accomplish, each member of D.I.'s team is proud of their decision to offer superior products and services better than anyone has before.

Roof Seamer Anodization


When you see a D.I. Roof Seamer, you will immediately recognize it due to its unique black and yellow color scheme. This is no accident! Several years ago, we decided that we needed something more to set us apart as the best Roof Seamer available. Anodization was the answer.

D.I. uses a process called anodization to ensure that the parts that make up a D.I. Roof Seamer are long-lasting and strong. During this anodization process, the components of the machine are tinted to the trademark black and yellow colors that you see on the Roof Seamer. The process actually changes the microscopic structure of the aluminum making it stronger, corrosion resistant and protecting it against wear.

D.I. installed our in-house anodization system in early 2008. When the components that make up a D.I. Roof Seamer leave the production line and go through Quality Control, they then proceed to Anodization. Here, personnel equipped with Class C Hazardous Material suits and respirators begin the detailed process of repeated acid washes, dyes, and chemical rinses. After the anodization process is complete, the finished product is a stronger, cleaner and longer lasting part to help build the best Roof Seamer for you.
