Smart Commercial Roofing That Protects Your Bottom Line
TPO, EPDM, PVC, modified bitumen, and metal systems installed with zero business interruption for Northwest Indiana retail, industrial, warehouse, and office properties.
Northwest Indiana's Smart Choice for Commercial Roofing
A commercial roof failure is never just a roof failure. It's lost inventory, canceled leases, insurance headaches, and interrupted operations. Smart Choice Exteriors installs and maintains commercial roofing systems across Northwest Indiana engineered to keep water out and your business running — from Merrillville's Broadway corridor to industrial parks in Portage, Hobart, and Valparaiso.
Our commercial team specializes in low-slope and flat roofing systems, tapered insulation to eliminate ponding water, and rooftop equipment coordination with your HVAC and refrigeration contractors. Every commercial project is delivered with a documented pre-install condition report, weekly progress updates, and a preventative maintenance plan built into the closeout package.
What Makes Our Commercial Work Different
Zero Business Interruption
We schedule around your operating hours, stage material to keep loading docks and entrances clear, and use dust and debris containment so retail and office tenants never notice we're there.
Tapered ISO Fixes Ponding
Standing water is the #1 killer of commercial membranes. We add tapered insulation to correct slope so water reaches drains and scuppers instead of sitting for weeks.
Full Warranty Systems
15, 20, and 30-year NDL (No Dollar Limit) manufacturer warranties from GAF, Carlisle, Firestone, and Johns Manville. Coverage that a facility manager can actually rely on.
Preventative Maintenance Plans
Annual and semi-annual inspection programs that keep small issues small — seam integrity, flashing details, drain function, and rooftop equipment penetrations.

From Free Estimate to Final Walkthrough
We measure the roof, cut a core sample to identify existing layers and R-value, and document every penetration, drain, and equipment location.
You receive a written spec with the recommended system, insulation R-value, wind uplift rating, and a comparison of overlay vs. tear-off pricing.
Deliveries, staging, and crane picks scheduled around your business. Daily dry-in so an unexpected storm never puts your inventory at risk.
Final inspection, warranty registration, and enrollment in our optional preventative maintenance program — all delivered as a digital closeout package.
Smart Materials, Honest Recommendations
We install what makes sense for your home and budget — never what pays the biggest commission. Here's what's on the menu for commercial roofing.
60- and 80-mil mechanically-fastened or fully-adhered TPO — bright white, energy-reflective, and the most popular commercial system in NWI.
Time-tested single-ply rubber roofing in 45- and 60-mil thicknesses. Excellent for large warehouse and industrial roofs.
Chemical- and grease-resistant PVC for restaurants, food processing, and any building with rooftop kitchen exhaust.
Torch-applied and cold-applied modified bitumen systems for small commercial and multi-family low-slope roofs.
40- to 50-year architectural and structural standing seam metal for storefronts, government buildings, and industrial facilities.
Smart Answers For NWI Homeowners
+Can you install over our existing commercial roof?
In many cases, yes — an overlay is faster and less expensive than a full tear-off. We cut a core sample first to make sure existing layers, insulation, and moisture content allow it.
+Do you handle rooftop HVAC coordination?
Yes. We work directly with your HVAC and refrigeration contractors to disconnect, lift, and reset units so flashings can be properly built underneath.
+How do you keep our business running during install?
We schedule material deliveries early, keep loading docks clear, use debris netting, and coordinate crew access to minimize noise during business hours.
+What commercial roof warranties do you offer?
15-, 20-, and 30-year manufacturer NDL (No Dollar Limit) system warranties from GAF, Carlisle, Firestone, and Johns Manville, plus our 5-year workmanship warranty.

How We Approach Commercial In Your Town
Northwest Indiana isn't one market. Soils, wind exposure, housing stock, and permit rules change from town to town — and so does the way we build.
Retail strips along US-30 get low-disruption TPO recovers scheduled around store hours.
Older industrial buildings often need tapered insulation and drain rework, not just a new membrane.
Warehouse and logistics roofs near the port face relentless lake wind — we upgrade perimeter fastening accordingly.
Offices, churches, and schools get phased installs so operations never stop.
