Frequently Asked Questions

“We Lead the Pack in Commercial Roofing Services Across Indiana”

What areas do you cover?

As a full-service commercial roofing company, we offer a wide array of services in all areas of Indiana and in the surrounding states as clients’ needs arise.

Our South Bend office covers all of northern Indiana, parts of central Indiana, and southwest Michigan.


What Roofing Systems do you install and service?
  • EPDM (rubber)
  • TPO
  • PVC
  • Standing-seam metal
  • Surface-fastened metal panels
My roof has a leak and it is under warranty, what do I do?

If you have your warranty paperwork, it will have a Warranty Services contact section. Call the manufacturer and report the leak. They will dispatch someone to address the leak. (Usually the original installing contractor)

If the leak is caused by a workmanship issue or a failing in the material itself, this will be covered under the warranty. If the leak was NOT caused by one of these, then it is not covered under the warranty and you will be charged for the service call.

If a roof leaks, is it ready to be replaced?

Not necessarily. For the same reason that when your car needs a repair, that does not mean it is ready to be replaced, simple repairs can usually be performed to get your roofing system back to a functioning state.

Your roofing system must be maintained and repaired in a timely manner to assure it lives out it’s full life expectancy. Making sure that leaks are repaired quickly will keep water from being trapped in the roofing system and leading to a premature failure.

Does hail damage flat roofs?

It can, but usually not. The membrane that covers most flat roofs runs between 45mils and 90mils. These membranes are usually thick enough to take the hail without damage to the roof.

That said, it certainly CAN damage the roofing system. Excessively large hail can damage components and some roofing membranes get brittle with age and can become more susceptible to damage as they age.

What is the difference between EPDM, TPO and PVC?

EPDM (Ethylene Propylene Diene Monomer) or rubber, was developed originally as a pond liner. It comes in sheets that vary in size from 10’ wide to 50’ wide and comes in lengths of 50’-200’. EPDM is easy to repair and can last for more than 20 years.

PVC (Poly Vinyl Chloride) is a familiar material in all aspects of our lives from household items to lawn chairs. These membranes are heat-welded together to form an almost monolithic membrane to cover your building. PVC offers excellent chemical-resistance, but can become brittle with age and must be treated carefully in its latter years.

TPO (Thermoplastic Poly Olefin) is similar to PVC in that it is heat welded and offers some chemical resistance, but TPO does not brittle with age and can come I a variety of colors.

Can I get a free estimate?

Yes. There is never a cost for providing you with an estimate for a roof replacement or large-scale repair. Our service departments do not offer estimates for simple repairs but will gladly offer an estimate if the repair is larger than a simple T&M (time and materials) service call.
