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.

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.
