Our Focus

We are exclusively a company with a focus on large metal roofing contracts.

Interstate Sheet Metal specializes in working on public works projects within the $100,000 to $5,000,000 range including both Preformed Metal Roofing and Siding. We do not install HVAC, metal counters or any other small jobs. We are exclusively a company with a focus on large metal roofing contracts.

We can fabricate just about anything you need. Most metal roofing, siding, flashing, caps, pans, hidden or exposed custom gutters, etc. Available in a variety of materials and colors. All standard and custom colors/finishes/anodizing of factory painted, galvanized, cold roll, aluminum, stainless and copper. We sell flat sheets, or you can provide the material to be fabricated.


You should know that our people’s comments to me concerning the performance of your company on this project have been consistently positive and appreciative. On my many visits to the project since you began your work I have time and again heard our people speak of your company as one of our finest subs. It is apparent that you too are committed to providing premier construction services, and without subcontractors such as ISM, there is no way we would be able to fulfill our Mission.

Thanks again for doing a great job for us on the MRHS project and for the very nice comments you’ve made concerning Mike and your experience with the Lydig team on this project. I hope we have the opportunity to work together on many future projects.
