The Roof Replacement Your Building Has Been Waiting For.
MAZE installs every major commercial roofing system — TPO, metal, modified bitumen, BUR, and SPF — and recommends the one that fits your building, your budget, and your 20-year plan.
Your roof is past its useful life. Repairs are recurring, energy costs are climbing, and the warranty expired years ago.
Every patch buys months, not years. Saturated insulation across 25%+ of the roof means you're paying to maintain a system that's failing at the assembly level.
MAZE evaluates whether replacement or restoration is the right call, recommends the system that fits, and phases installation so your building stays operational throughout.
MAZE Replacement Process
Every MAZE replacement follows a structured five-step process designed to eliminate surprises, match the right system to your building, and minimize operational disruption.
Condition Assessment
Comprehensive evaluation including core cuts, infrared moisture survey, structural review, and drainage analysis. We determine the true condition of every layer — not just the visible surface.
System Recommendation
Based on building profile, structural capacity, slope, operational requirements, and budget, we recommend a specific roofing system with supporting rationale and trade-off analysis.
Budget Proposal
Detailed proposal with material specifications, labor scope, phasing plan, project timeline, warranty options, and total cost. No hidden line items or surprise change orders.
Phased Installation
Section-by-section installation keeps your facility operational. Each zone is fully waterproof before moving to the next. Coordinated with your team on noise, access, and scheduling.
Warranty Activation
Manufacturer warranties registered, as-built documentation delivered, material certifications provided, and first maintenance inspection scheduled.

Replacement Projects
“MAZE replaced 120,000 square feet of TPO on our warehouse while we ran 24/7 operations. They phased the work section by section — we never lost a single day of production. The crew was professional and the site was clean every evening.”
Operations Director
Facility Management, 120,000 sq ft Warehouse
“We got three bids for our office complex replacement. MAZE was the only contractor who recommended a different system than what we asked for — and they were right. Two years in, the energy savings alone are covering the cost difference.”
Asset Manager
Capital Planning, 3-Building Office Complex
“The manufacturer warranty registration was handled before we even asked. Complete documentation package, as-built drawings, material certs — everything our insurance carrier needed was in one binder.”

Commercial Roofing Systems Compared
MAZE installs every major system. The right choice depends on your building, your budget, and your ownership timeline.
| System | Lifespan | Best For | Cost |
|---|---|---|---|
| TPO | 20-30 yr | Large flat roofs | $$ |
| Metal Panel | 40-60 yr | Industrial / warehouse | $$$ |
| Modified Bitumen | 20-25 yr | Office / retail | $$ |
| BUR | 25-30 yr | Heavy-traffic rooftops | $$ |
| SPF Foam | 20-30+ yr | Irregular shapes / high R-value | $$ |
Replace vs. Restore: The Decision Framework
Not every aging roof needs a full tear-off. The decision depends on four measurable factors: the percentage of roof area with saturated insulation (over 25% typically favors replacement), the condition of the structural deck, whether the existing system has exceeded its designed lifespan, and code compliance requirements that may mandate a full assembly upgrade.
If the substrate is dry, the deck is sound, and the membrane is structurally intact, a coating restoration can extend the roof's life by 10-20 years at significantly lower cost. MAZE evaluates both options on every project and presents a clear comparison — we do not default to the higher-revenue recommendation.
Phased Installation for Occupied Buildings
A roof replacement on an occupied commercial facility is an operational coordination challenge as much as a construction project. Tenants need advance notification. Loading docks may require temporary relocation. Noise-sensitive operations must be identified and scheduled around. MAZE develops a phasing plan for every replacement that accounts for your building's operational requirements.
We work section by section, ensuring that completed areas are fully waterproof before moving to the next zone. Material staging is planned to avoid blocking access points. Debris management keeps the site clean. Daily coordination with your facility team keeps everyone informed and reduces disruption complaints.
Warranty Structures
Commercial roof warranties are not all created equal. A standard manufacturer material warranty covers defects in the membrane or components but may not cover labor for repairs. Enhanced warranties — including NDL (No Dollar Limit) options — cover both materials and labor at no additional cost to the building owner for the warranty term. The availability and duration of these warranties depend on system type, mil thickness, and installer certification level.
MAZE is certified by multiple manufacturers to install warranty-eligible systems. After installation, we register all warranties, deliver complete project documentation including as-built drawings and material certifications, and schedule your first preventive maintenance inspection.
