Completed Commercial Job — Merrillville, IN
Full commercial re-roof at a large storage facility complex on US-30 in Merrillville — multiple buildings, hundreds of squares of architectural shingles, hand-soldered flashings throughout.
Large-scale commercial re-roofing for storage facilities, warehouses, and multi-building complexes across Lake County and Northern Indiana. 29 years of roofing experience. Hand-soldered flashings on every job.
Merrillville is one of Northern Indiana's major commercial corridors — and the commercial roofing needs here reflect that. Large storage complexes, distribution warehouses, retail centers, and multi-unit commercial properties line US-30 and I-65. These aren't small residential jobs. They require a contractor with the crew capacity, material logistics, and project management experience to execute a large-scale re-roof without disrupting operations.
Great American Roofing has completed full commercial re-roofs on large storage and warehouse complexes in the Merrillville area. Every flashing is hand-soldered — pipe boots, wall junctions, valleys, and penetrations — using an old-school tin man technique that creates permanent waterproof seals. On a commercial roof with dozens of penetrations, the flashings are where most failures begin. We don't cut corners on them.
Commercial projects in Lake County get the same level of attention as our largest Greater Cincinnati jobs. We bring 29 years of roofing experience, a clean track record on large multi-building complexes, and honest, no-pressure project assessments.

We install architectural shingles, TPO, EPDM, and modified bitumen systems for commercial applications.

We evaluate each property and recommend the best system for the application and budget.
We hand-solder every flashing — pipe boots, wall junctions, valleys, and every penetration point — using old-school tin man technique. On a large commercial roof with dozens of penetrations, flashings are where most failures start. Soldered flashings create a permanent waterproof bond that outlasts the shingles. Combined with 29 years of experience on large-scale commercial jobs, it's a level of craftsmanship most regional contractors don't offer.
