TPO, EPDM, or modified bitumen — which is best for my building?

It depends on slope, drainage, foot traffic, equipment loads, and budget. TPO is the most common for new replacement; EPDM has a 40-year track record; mod-bit is excellent for cut-up roofs with heavy traffic. We engineer the recommendation per building.

Will the building have to close during the install?

Almost never. We phase work to keep the building dry and operational. Some welding work may require fire-watch coordination, and overnight or weekend scheduling is available for sensitive operations.

What warranty terms are available?

System warranties up to 25 years (material + labor) are available on qualifying TPO and EPDM systems when installed by certified contractors. We hold those certifications and register every qualifying job.

Can you handle tapered insulation for drainage?

Yes — every replacement includes a drainage review. If the existing roof ponds, we engineer a tapered ISO package to direct water to drains and scuppers per code.

About Commercial Roof Replacement

Replacing a commercial roof isn't just a construction job — it's an operations problem. Tenants stay in the building, employees keep working, and the roof above their heads gets rebuilt without disrupting either. That coordination is what separates a real commercial roofer from a residential crew working out of their league.

We replace flat and low-slope commercial roofs across central Indiana — single-tenant industrial, multi-tenant office, retail strip, light manufacturing, and multi-family. Our standard systems are TPO (60 or 80 mil), EPDM (.060 or .090), and SBS modified bitumen, with tapered ISO insulation packages engineered for proper drainage to existing drains and scuppers.

Every project starts with a real engineering scope: existing condition, attachment method (mechanically attached, fully adhered, or ballasted), insulation R-value calculation, drainage check, and a phased plan that keeps the building dry and operational through the install. We don't open more roof than we can dry-in by the same evening.

Manufacturer warranties on commercial single-ply systems can run 15, 20, or 25 years with system warranty options that cover both material and labor. Those warranties require certified installers and documented installation — both of which we hold for Carlisle, Versico, GAF, Johns Manville, and Firestone product lines.

Tenant coordination is built into our schedule. We work with property management on parking displacement, loading-dock access, fire-alarm isolation when membrane is being torch- or hot-air welded, and after-hours scheduling when daytime operations can't tolerate noise or odor.

Our process

01
Pre-construction scope & drainage review
Existing condition documented, drainage analyzed, insulation package and system engineered to manufacturer spec and energy code.
02
Phased install plan
Building stays dry every night. We open only what can be dried-in by end-of-day and coordinate with tenants and property management.
03
Certified installation
Crews certified on Carlisle, Versico, GAF, and Johns Manville systems install per manufacturer spec for full system warranty eligibility.
04
Punch, inspection, & warranty registration
Manufacturer field inspection, owner walk-through, and warranty registration submitted within 30 days of completion.
