What is the typical lifespan of a commercial roof?

As general industry figures, well-maintained EPDM, TPO and PVC roofs commonly last 20 to 30 years or more, built-up roofs 20 to 30 years, and metal roofs longer. Maintenance makes a big difference; a neglected roof can fail early.

What's the difference between TPO and EPDM roofing?

TPO: usually white and reflective, with heat-welded seams, so it can lower cooling loads. EPDM: a rubber membrane with a long track record, usually black, with taped or adhered seams. It often costs less up front. The right choice depends on budget, roof complexity, rooftop traffic and energy goals.

How often should commercial roofs be inspected?

Twice a year (spring and fall) and after severe storms is a common recommendation. Regular maintenance includes debris removal, drain cleaning, sealant and flashing checks. Many manufacturer warranties also require documented maintenance.

How much does commercial roof repair or replacement cost in Indianapolis?

Most commercial roof repairs SPG sold from 2024 through 2026 ran $1,300 to $3,800. For replacement, as general industry ranges (not SPG quotes), TPO and EPDM typically run $4 to $8 per square foot installed, PVC $6 to $10, and metal $8 to $12 or more. Roof size, tear-off, insulation and details move the price. We give a written quote after an on-site assessment.

Can you repair our existing roof or do we need replacement?

Many commercial roofs can be repaired, especially when the damage is localized. We check membrane condition, seams and flashings. If the roof is near the end of its life or wet insulation is widespread, replacement or a recover is usually the better investment. We will give you an honest assessment.

TPO Roofing Systems

Thermoplastic Polyolefin (TPO) is a single-ply membrane, usually white, with heat-welded seams. The reflective surface absorbs less heat than a dark roof, which can lower cooling loads, and TPO resists UV exposure and stays flexible through Indiana's temperature swings. TPO is the system we quote most often on commercial flat roofs. It suits warehouses, retail centers, offices and multi-family buildings. See our TPO roofing page for more.

Why SPG

A Commercial Roofing Company Indianapolis Property Managers Use

131 of our commercial jobs since 2018 were for property management companies, and 166 of our commercial roofing jobs were in Indianapolis. Property managers use us because the same company can handle the roof, gutters, siding and windows on a building, and because we document what we find with photos before we quote anything.

Every commercial job starts with a roof assessment: membrane condition, seams, flashings, penetrations and drainage. You get the photos and a written scope, and we recommend a repair when a repair will do the job. Certificates of insurance are available on request.

EPDM Rubber Roofing

EPDM (Ethylene Propylene Diene Monomer) is a rubber membrane with a long track record on commercial roofs. It is usually black, so it absorbs more heat unless it is coated, and its seams are adhered with tape or adhesive rather than welded. EPDM handles weathering and foot traffic well and works on roofs with many penetrations. We install, repair and recover EPDM roofs. See our EPDM roofing page.

Commercial Roof Repair and Coatings

Many commercial roof leaks come from a few places: open seams, failed flashing at walls and curbs, punctures, and ponding water around clogged drains. A targeted commercial roof repair often fixes them without replacing the roof. Most commercial roof repairs SPG sold from 2024 through 2026 ran $1,300 to $3,800.

When a membrane is aging but still sound, a roof coating can be an option before full replacement. We have applied acrylic and silicone coating systems on commercial roofs, and we will tell you whether your roof is a good candidate.

Preventive Flat Roof Maintenance

Routine inspections catch small issues before they become leaks. Maintenance visits include debris removal, drain cleaning, sealant and flashing checks, and repairs to blisters, punctures and seams. We document each visit with photos so you can track the roof's condition and plan for replacement. See commercial roof maintenance.

Storm Damage and Emergency Leaks

Wind-lifted seams, hail damage and storm leaks can disrupt a business. Our answering service takes calls 24/7. Most emergency calls are handled the next business day, and after major storms our crews have come out sooner. We document the damage with photos and a written scope, and if you file an insurance claim we meet the adjuster on site. See commercial storm damage.

What Our Customers Say

Forest B.

“SPG is my go-to roofing company. As a commercial real estate broker with many options for roofing companies, Dustin is always my first call when I need a roof checked on. I have had him hop on many roofs between my personal rentals and countless clients. They are always professional, competitively priced, and very responsive. I highly recommend SPG for any residential or commercial roofing needs.”

Rhonda R.

“Chris Sheets showed up at my home and was a breath of fresh air with his professional demeanor after the horrible HVAC installation I experienced. Chris walked my home to visually inspect the install and the damage done and gave a quote with detailed explanation of what he said needed to be done to resolve the issues, starting with the roof where the furnace jack was installed incorrectly causing water damage. He was very detailed as he walked my entire roof to find any issues and has resolved them all at this time. I would recommend SPG, as Cameron was very helpful also. Job well done, SPG Roofing!”
