Framework
Repair, maintain, replace
Modex works commercial membrane roofs in three lanes. Each has its own timeline, cost, and best-fit scenario. We help you pick the one that fits the building.
Fix what's broken
Repair — leak fixes and storm damage
Localized failures — seam splits, flashing gaps, drain failures, hail or wind damage — get patched and re-sealed. Per-incident repair runs $500 to $15,000 depending on scope. Lowest-cost lane. Best for buildings 2 to 15 years into a mostly-intact membrane where the problem is local, not systemic.
Decision
What drives the choice
Property managers and building owners evaluate roofing decisions on four criteria — cost, maintenance, longevity, and warranty. Modex builds every quote around all four.
Cost
Capital vs operating expense
Repair costs less upfront — $500 to $15,000 per incident. Maintenance spreads cost across years — $1,500 to $8,000 annually. Replace is highest capital — $4 to $14 per square foot — but eliminates the drumbeat of emergency calls.
Maintenance
Predictable annual budget
Annual maintenance programs run $1,500 to $8,000 depending on building size and inspection frequency. Budgetable. Predictable. Catches small issues before they escalate.
Longevity
20 to 40+ year membrane life
Mule-Hide TPO and PVC carry 20 to 30 year service lives. EPDM and modified bitumen reach 25 to 40+ years with active maintenance. The right system on the right building stretches the reroof window decades.
Warranty
10-year workmanship plus Mule-Hide material coverage
Modex backs the install for 10 years on commercial scope (residential lifetime workmanship does not apply to commercial). Mule-Hide manufacturer warranties cover the membrane material and transfer to the next building owner — depth of coverage varies by system. The combination is what gives the warranty paperwork its real teeth.
Warranty
What the warranty actually covers
Warranty depth
Modex 10-year workmanship warranty covers labor and installation on commercial scope. Mule-Hide manufacturer warranty covers the membrane material — coverage period varies by system.
Transferability
Mule-Hide manufacturer warranties transfer to the next building owner. Useful when the property changes hands — protects asset value and reduces buyer-side roof contingency on the sale.
Single-source accountability
One contractor handles repair, maintenance, and replacement. No finger-pointing between the roofer and the manufacturer when an issue surfaces — we own the whole system.
Payment
Escrow payment structures for replacements
On full replacement projects, Modex offers escrow payment structures. Funds release on milestone completion verified by the property manager. Protects building owners from deposit-fronting tactics and ensures work quality before final payment.
Systems
Why Mule-Hide systems stand out
Mule-Hide membranes come with factory-backed material warranties that layer on top of Modex's 10-year workmanship coverage. TPO, EPDM, modified bitumen, and PVC — material warranties transfer to the next building owner per Mule-Hide's terms, and the systems hold up through Minnesota's freeze-thaw cycles.
Advantage
Why Modex for commercial roofing
One contractor handles repair, maintenance, and replacement. No switching vendors or managing multiple warranties. We own the outcome from first inspection to final invoice.
