Commercial Roofing in Indianapolis, IN

From downtown offices and Mass Ave retail to the warehouses and distribution centers along I-70, I-65, and the airport logistics corridor, Indianapolis runs on buildings that depend on flat and low-slope roofs. Those systems face a tough Indiana climate: ponding water after heavy rain, hail and high winds from spring and summer storms, and repeated freeze-thaw cycles that work seams and flashings loose over the winter. Left unaddressed, a small membrane failure becomes interior damage, inventory loss, and downtime.

SPG Roofing & Exteriors installs, repairs, and maintains commercial roofing systems for property managers, building owners, and general contractors across Marion County and Central Indiana — with a focus on keeping your operation running while we work.

We are certified to install leading low-slope and flat-roof systems, and we help you match the system to your building, budget, and energy goals:

• TPO membrane: Energy-efficient, reflective single-ply roofing well suited to warehouses and large retail footprints.
• EPDM rubber: Proven, durable single-ply membrane that performs through Midwest temperature swings.
• PVC membrane: Strong seam welds and chemical resistance for restaurants and buildings with rooftop grease or exhaust.
• Modified bitumen and built-up systems: Multi-ply protection for low-slope roofs with heavy foot traffic.
• Metal and coatings: Standing seam systems and restoration coatings that can extend the life of an existing roof.

We install manufacturer-backed systems from Duro-Last, Versico, Johns Manville, and Elevate, which means access to strong, fully backed warranties.

• New installation & re-roofing: New construction and full system replacement scoped to your building and timeline.
• Repair & leak detection: Fast diagnosis and repair of membrane punctures, failed seams, and flashing leaks.
• Preventive maintenance programs: Scheduled inspections and upkeep that protect your warranty and catch problems early.
• Storm damage & insurance work: Documentation and repair after hail and wind events, including insurance claim support.

Every project starts with a free, no-pressure roof inspection and a clear written scope.

If you are weighing a repair, restoration coating, or full replacement, our inspection gives you the information to decide — not a hard sell.

Commercial work lives or dies on logistics. We schedule around your operating hours, keep the site clean and safe, and communicate at each milestone so there are no surprises.
