Quick Answer: TPO Installation in Selma
TPO roof installation in Selma typically runs between $6.50 and $11.50 per square foot installed, depending on membrane thickness, insulation R-value, attachment method, and tear off requirements. Most commercial projects take 5 to 14 working days. Expect a 15 to 25 year service life when the system is specified and installed correctly.
TPO Cost Breakdown for Selma Buildings
Pricing varies based on roof size, deck condition, code required insulation, and whether the old roof stays or comes off. The table below reflects ranges we see on typical Central Indiana commercial projects.
| Cost Component | Typical Range | Notes |
|---|---|---|
| TPO membrane (material only) | $1.50 to $2.80 per sq ft | Varies by mil thickness |
| Polyiso insulation | $1.80 to $3.50 per sq ft | Code minimum R-30 in Selma |
| Cover board | $0.60 to $1.20 per sq ft | Recommended for hail resistance |
| Labor and fasteners | $2.00 to $3.50 per sq ft | Mechanical or adhered |
| Tear off and disposal | $1.00 to $2.50 per sq ft | Skip if recover is allowed |
| Flashings and edge metal | $0.50 to $1.20 per sq ft | Penetrations, parapets, drains |
What Drives Your Price Up or Down
- Roof size: larger projects gain efficiency, so cost per square foot drops
- Deck condition: rotted decking or wet insulation adds replacement labor
- Number of penetrations: HVAC curbs, vents, and drains each need flashing
- Attachment method: fully adhered costs more than mechanically fastened
- Warranty length: 20 and 30 year manufacturer warranties require specific specs
- Building height and access: cranes or extended boom lifts add staging costs
- Tapered insulation packages: required when ponding water is present, adds $1.00 to $2.50 per sq ft
Hidden Costs to Plan For
Selma Commercial Roofing provides line item estimates so owners in Selma can see exactly where dollars go. Common add ons that surprise first time buyers include lightning protection reinstallation, gas line re supports, satellite dish relocation, and skylight curb rebuilds. We flag these during the pre bid walk so they are budgeted, not invoiced as change orders later.
TPO Project Timeline in Selma
| Roof Size | Typical Duration | Crew Size |
|---|---|---|

| 10,000 to 30,000 sq ft | 7 to 12 working days | 6 to 8 |
| 30,000 to 75,000 sq ft | 2 to 4 weeks | 8 to 12 |
| Over 75,000 sq ft | 4 to 8 weeks | 10 to 15 |
Weather Factors in Central Indiana
- TPO welds require deck temperatures above 40 degrees F for reliable seam strength
- Adhesive applications need dry surfaces and no rain in the forecast
- Winter installs are possible with primer adjustments but pace slows
- Spring and fall offer the most predictable install windows
- Summer humidity can extend adhesive flash times, so crews stage smaller sections
Minimizing Business Disruption
For occupied buildings in Selma, we sequence work to keep tenants productive. That means staging materials at night for retail centers, isolating HVAC zones so dust does not pull into return air, and scheduling crane lifts before opening hours. Tenant notification letters are provided in advance so everyone knows when their section of roof is in progress.
The TPO Installation Process Step by Step
Our crews follow a consistent sequence so nothing is skipped and the roof passes manufacturer inspection. If you are still comparing systems, our TPO vs EPDM vs PVC comparison walks through which membrane fits which building type.
- Pre install inspection. Core samples confirm deck type, existing insulation, and moisture. Drains, scuppers, and parapet conditions are documented.
- Tear off or recover decision. Code in Selma generally allows one recover. If the existing roof is wet, full tear off is required.
- Deck prep. Damaged metal or wood decking is replaced. Fasteners are tested for pullout values.
- Insulation layout. Polyiso boards are staggered and mechanically fastened or adhered to meet R-value and wind uplift requirements.
- Cover board installation. A high density board adds puncture and hail resistance under the membrane.
- Membrane installation. TPO sheets are rolled out, fastened or adhered, and hot air welded at all seams.
- Flashings and details. Pipe boots, curbs, drain bowls, edge metal, and termination bars are installed.
- Seam probe and final walk. Every weld is probed with a cotter pin tool. Punch list items are corrected before sign off.
Repair, Recover, or Full Replacement
Not every leaking roof needs replacement. If your membrane has scattered punctures but the insulation is dry, targeted commercial roof repair often buys five or more years. If saturation is widespread or seams are failing across the field, replacement is the honest answer. We document moisture readings and core results in writing so you can make the call with real data, not pressure. For buildings actively leaking during a storm, our emergency roof repair crews prioritize tarping and dry in before scheduling the full installation.
Inspection Points Before Sign-Off
- All field seams probed and re welded if voids are found
- Drain bowls clamped and sealed
- Termination bars caulked with manufacturer approved sealant
- Walkway pads at access points and around RTUs
- Manufacturer warranty inspection scheduled within 30 days
- As built drawings and warranty paperwork delivered to the owner
Post-Install Maintenance Schedule
To protect the warranty and stretch service life toward the upper end of the 15 to 25 year range, Selma Commercial Roofing recommends semi annual inspections every spring and fall, drain clearing after heavy leaf drop, and a seam check after any major hail event. Small issues caught early, like a lifted T-joint patch or a loose pitch pan, cost a fraction of what a saturated insulation replacement runs later.
