These guys are awesome, they get the job done right, I had no issues after they fixed the roof and they made sure that the roof didn't have any holes. If my camera was working I would definitely post them but looks new and there are no leaks. These guys are awesome I know I would recommend them to anyone. On top of that the inspection was free and the payment was just roofing materials and labor!!

Common Questions About Hiring a Flat Roof Contractor in Northwest Indiana
How do I know if my flat roof needs repair or a full replacement?
A flat roof that has isolated seam failures, a puncture, or minor blistering is usually a repair candidate. Once moisture has saturated the insulation layer or more than 25 percent of the membrane has lost adhesion, replacement typically delivers better long-term value. A free inspection from Indiana Roofing Company gives you a written assessment so you can make that decision with real information.
Does Indiana Roofing Company handle both residential and commercial flat roofs?
Yes. Indiana Roofing Company installs, repairs, and replaces flat roof systems on residential homes, commercial buildings, and industrial facilities across Northwest Indiana. The same licensed crew handles every property type — there is no separate residential division and no subcontracting on commercial work.
What flat roof materials do you install in Hammond and Northwest Indiana?
Indiana Roofing Company installs TPO (thermoplastic polyolefin), PVC (polyvinyl chloride), EPDM (ethylene propylene diene monomer rubber), and modified bitumen systems. Each material suits different building types and budgets. We explain the trade-offs for your specific roof during the free inspection so you can choose with confidence.
How quickly can Indiana Roofing Company respond to a flat roof leak?
For most Northwest Indiana locations, we can have a licensed roofer on-site the same day you call, depending on the time of day. After-hours calls are welcome. Our Hammond base puts us within 30 minutes of most Lake County addresses, so response times are short compared with contractors travelling from Chicago or Indianapolis.
Are estimates and inspections really free with no obligation?
Every inspection and written estimate from Indiana Roofing Company is completely free. There is no service call fee, no diagnostic charge, and no pressure to proceed. We inspect the roof, document what we find, and explain the options. The decision is yours.
