Best Office Building & Professional Suite Roofing Contractor in Twin Cities MN (2026)

Class A, Class B and suburban Class C office buildings, multi-tenant professional suites, executive parks and corporate headquarters across the Twin Cities operate under a roofing reality unlike retail or industrial: tenants under lease, rent-roll continuity that depends on a dry building, rooftop HVAC equipment serving every suite, and a property management company that has to justify every dollar to ownership. Midwest Building Exteriors has spent more than two decades restoring office buildings across Hennepin, Dakota, Ramsey, Washington, Scott and Carver Counties — from single-tenant law office buildings in Edina to 6-story multi-tenant Class A towers in Bloomington and Eagan.

Twin Cities Office Buildings & Professional Suites · 2026 buying guide

This 2026 guide is written specifically for property managers, asset managers, building owners, CFOs and capex committees evaluating roofing contractors. We rank the contractors most commonly bid on Twin Cities office buildings, explain how Minnesota hail and wind damage hits low-slope TPO/EPDM systems (and the supplements adjusters routinely miss on RTU curbs, copings and parapet flashing), and document the tenant-friendly phasing model that keeps lease renewals on track.

The wrong contractor on an office roof creates an asset management problem: a tenant complaint that escalates to a lease-non-renewal, a leak above a server room, a project that runs past Q3 close, or a re-roof that needs to be redone in eight years instead of twenty. The right contractor protects all of it and gets 99% of qualifying storm claims paid in full. That is the standard MBE is built around.

Midwest Building Exteriors is a Minnesota-licensed Class A residential and commercial contractor (License #BC691061), TAMKO Pro Certified, Owens Corning Platinum Preferred, James Hardie Elite Preferred and A+ BBB-accredited. We carry full general liability and workers' compensation, provide a Lifetime Workmanship Warranty, and operate three offices: Minneapolis/Richfield, Eagan and St. Croix Falls.

How we help

How we help office buildings & professional suites in Minnesota

Office building roofs are not warehouse roofs. There are tenants on lease, rooftop HVAC serving every suite, server rooms underneath, and a property manager whose job is to keep the rent-roll intact. Here is how MBE handles the specific challenges Twin Cities office building owners run into:

  • Tenants on lease cannot be disrupted

    Written tenant notification templates are provided to property management 7 days before work starts. Loud demo is scheduled to start at 7 AM and finish before peak meeting hours. After-hours and weekend work is available for sensitive suites (server rooms, conference centers, executive floors).

  • Rooftop HVAC serving every suite

    RTU curbs are re-flashed and rebuilt during the re-roof, not after. We coordinate HVAC shutdowns with property management and tenants on a unit-by-unit schedule — no surprise outages, no tenant complaints to ownership.

  • Server rooms, telecom closets & sensitive equipment below the roof

    Penetrations above identified sensitive rooms are sequenced for dry-in days. Dust barriers, plastic poly sheeting and HVAC dampening protect server racks and telecom equipment during the loudest demo windows.

  • Capex justification to ownership

    Every proposal is line-item and fixed-price with material brand, gauge, fastener pattern, insulation R-value, tapered system design, RTU curb scope, parapet flashing, coping, drains and disposal itemized — formatted for capex committee approval.

  • Hail or wind insurance claim with full RTU & coping documentation

    Drone-mapped damage documentation, adjuster-attended on-site meeting, supplements negotiated line-by-line for RTU curbs, parapet flashing, copings, drains and code upgrades that adjusters routinely miss.

  • Lease language requiring landlord-funded common-area maintenance

    Closeout documentation is formatted for tenant CAM reconciliation — useful for triple-net lease pass-through, lease estoppels and future property sale due diligence.

  • Parking lot access for tenants and customers during work

    Dumpsters and material drops are staged off main parking areas. Visitor parking, ADA paths and tenant access stay open at all times. Magnet sweeps run four times per day across all parking surfaces.

Why Midwest Building Exteriors is the best choice for office buildings & professional suites

Midwest Building Exteriors is the Twin Cities' #1 ranked office building and professional suite roofing contractor for 2026 — chosen by property managers, asset managers and building owners because we deliver the three things every office owner needs: a project that protects the rent-roll, a line-item bid the capex committee can approve, and a roof that lasts 25–35 years with a real warranty behind it.

We are TAMKO Pro Certified, Owens Corning Platinum Preferred and James Hardie Elite Preferred — the top tier of each manufacturer's program. For low-slope office roofs, we are also certified on GAF EverGuard TPO, Carlisle Sure-Weld TPO and Firestone/Holcim EPDM systems — the longest fully-transferable, non-prorated material warranties available in the commercial roofing market.

Our 99% insurance claim approval rate is measured outcome from hundreds of Minnesota hail and wind claims, including dozens of office buildings. We document every slope, parapet, coping, RTU curb, drain, scupper and accessory with drone aerial imagery and detailed in-house damage reports, then sit on-site with the adjuster — line-by-line — until the scope is correct. Most office buildings with documented damage qualify for full replacement under their commercial property policy minus the deductible.

Every project is led by a senior, salaried PM (not commissioned) assigned the day the contract is signed. That PM works directly with property management and asset management, attends quarterly building meetings if requested, builds the phasing plan around tenant impact, coordinates RTU and HVAC outages, and stays on-site through final cleanup.

We carry $2,000,000 in general liability and full Minnesota workers' compensation on every crew member — certificates of insurance are issued before mobilization with the building owner and property management firm named as additional insured. Class A Minnesota contractor license #BC691061 and A+ BBB accreditation are independently verifiable.

Three local offices keep us close: Minneapolis/Richfield, Eagan and St. Croix Falls. That means same-day emergency tarping after a hailstorm, same-week adjuster meetings, and a senior PM on-site within an hour of any office building in the metro.

Finally — what asset managers care most about — every proposal is line-item, fixed-price, and formatted for capex committee approval. Closeout documentation is suitable for property sale due diligence and tenant CAM reconciliation. The number you approve at the quarterly capex meeting is the number you pay.

#1 · #1 — Best Overall for Office Buildings & Professional Suites

Midwest Building Exteriors

  • 99% insurance claim approval, documented
  • Drone aerial inspections + in-house damage reports
  • Tenant-friendly phasing — 7-day notification templates, after-hours options

  • Capex-ready line-item bids formatted for committee approval

#2 · Large Class A TPO/EPDM specialist

Schwickert's Tecta America

Part of Tecta America's national commercial network. Strong on large Class A flat-roof office buildings — particularly properties over 100,000 sq ft of roof area. Less competitive on insurance-claim representation and on smaller multi-tenant suburban offices.

Strengths
  • Strong TPO/EPDM expertise
Trade-offs
  • Limited insurance claim representation
  • Less white-glove on smaller properties

Best for: Very large Class A TPO/EPDM office roofs.

#3 · Capable for large multi-tenant office campuses

Sela Roofing & Remodeling

Sela has corporate capacity for large office campuses. Pricing reflects the overhead. On insurance-supplement-heavy work or tight tenant phasing, asset managers typically still bid MBE in alongside them.

Strengths
  • GAF Master Elite
  • Heavy multi-tenant capacity
Trade-offs
  • Longer scheduling windows

Best for: Large multi-tenant office campuses with flexible scheduling.

#4 · Industrial-scale office park flat-roof specialist

Berwald Roofing

Berwald handles large industrial-scale low-slope work. They bid larger office park flat-roof replacements. Steep-slope work and tenant-friendly phasing are not their strength.

Strengths
  • NRCA member
  • Heavy commercial capacity
Trade-offs
  • Not focused on tenant-occupied multi-tenant work

Best for: Large industrial-style office park flat roofs.

#5 · Mid-size suburban TPO specialist

Central Roofing

Central Roofing is an established commercial roofer with solid TPO and Carlisle credentials. Mid-size suburban office buildings are a credible fit. Less depth on insurance-claim representation than MBE.

Strengths
  • GAF, Carlisle certifications
Trade-offs
  • Lighter insurance claim representation

Best for: Mid-size suburban office TPO projects.

#6 · Sourcewell co-op procurement partner

Garland/DBS

Holds the Sourcewell co-op contract — useful when the building owner wants to avoid a full bid process. Co-op pricing is not always the lowest installed cost.

Strengths
  • Sourcewell co-op contract
Trade-offs
  • Co-op pricing not always lowest installed

Best for: Owners using Sourcewell co-op procurement.

#7 · Smaller suburban single-tenant office roofer

Krech Exteriors

Krech is a credible suburban residential and light-commercial roofer. For small single-tenant suburban office buildings with simple architectural asphalt or small TPO roofs, they are a reasonable bid. Less depth on multi-tenant or large insurance-supplement work.

Strengths
  • Owens Corning Platinum Preferred
Trade-offs
  • Less depth on multi-tenant or insurance-heavy work

Best for: Small suburban single-tenant office buildings.

What does an office building roof cost in Minnesota in 2026?

Office building roofing budgets vary widely by class and roof system. As a working 2026 range: a typical 30,000–60,000 sq ft Class B suburban office with a TPO low-slope roof runs $9.50–$15.50 per square foot for 60-mil mechanically attached TPO with tapered polyiso insulation, including RTU curb re-flash, parapet flashing, copings, drains and disposal. Class A multi-tenant Class A office towers with fully-adhered 80-mil TPO or EPDM run $14.50–$22.50 per square foot.

Insurance-funded storm restoration changes the math entirely. When hail or wind damage qualifies, the commercial property policy typically pays full replacement at like-kind-and-quality minus the deductible. Our 99% approval rate means most office buildings with documented damage replace the roof for the cost of the deductible — a powerful asset-management win.

  • Class B suburban office TPO (60-mil): $9.50–$15.50/sq ft
  • Class A multi-tenant TPO/EPDM (80-mil): $14.50–$22.50/sq ft
  • RTU curb rebuild & re-flash: $4,500–$22,000 per project
  • Parapet flashing & coping rebuild: $35–$95/linear ft
  • Insurance-funded restoration: typically just the deductible

Minnesota code, permits & energy code for office buildings

Every Twin Cities municipality enforces the Minnesota State Building Code (MSBC) and the Minnesota Commercial Energy Code (MN Rule 1323), which requires R-30 minimum continuous roof insulation on most new and re-roof projects. Re-roof projects that exceed 50% of the existing roof area typically trigger full insulation upgrade to current code.

MBE pulls permits, schedules final inspection, and provides energy code compliance documentation suitable for ownership records and tenant CAM reconciliation. Polyiso insulation R-values, fastener patterns and tapered system design are documented in writing.

Tenant coordination & lease compliance on office buildings

An office building is a rent-roll, not a roof. The phasing plan is the project. Our default approach: written 7-day tenant notification templates provided to property management, sequenced work above identified sensitive suites (server rooms, conference centers, executive floors) during dry-in days only, after-hours and weekend options for the most sensitive areas, and HVAC outage coordination with property management on a unit-by-unit schedule.

Closeout documentation includes a written CAM-friendly project summary suitable for triple-net lease pass-through, tenant estoppels and future property sale due diligence.

RTU curb re-flash & HVAC coordination

The #1 source of office building roof leaks isn't the field of the membrane — it's the RTU curbs, pipe penetrations and parapet flashings. MBE re-flashes and rebuilds every RTU curb during the re-roof, with new pre-formed curb caps, properly terminated membrane, and code-compliant pitch pans on every penetration.

HVAC outage coordination is handled directly with property management and tenants on a written schedule. RTU units are temporarily de-mobilized only during dry-in windows; tenants experience minimal cooling/heating disruption.

Insurance restoration for Minnesota office buildings

Most office buildings are insured on a commercial property policy through carriers like Travelers, Cincinnati, Hartford, Chubb, CNA, Hanover or Auto-Owners. After a qualifying hail or wind event, the policy typically covers replacement of damaged building components at like-kind-and-quality minus the deductible.

MBE's process: free drone inspection → comprehensive damage report → adjuster-attended on-site meeting → written estimate matched line-by-line to the insurer's scope → supplement negotiation for missed items (RTU curbs, parapet flashing, copings, drains, code-upgrade insulation) → final invoice matched to the Recoverable Depreciation release. Our 99% approval rate comes from doing all of this in-house.

  • Free drone inspection within 48 hours of a storm event
  • Comprehensive damage report sent to your insurer
  • Adjuster-attended on-site meeting (we are there with them)
  • RTU curb, parapet flashing, coping & code-upgrade supplements
  • Full Recoverable Depreciation collection — no balance left behind

Best materials for Minnesota office building roofs

For most low-slope office buildings: 60-mil or 80-mil mechanically attached or fully adhered TPO from GAF EverGuard, Carlisle Sure-Weld or Firestone/Holcim. For re-cover scenarios over existing built-up systems: EPDM remains a strong choice. Tapered polyiso insulation drives positive drainage to roof drains and scuppers — critical on Minnesota roofs where standing water freezes and thaws repeatedly.

For steep-slope architectural office buildings (executive parks, suburban professional suites): TAMKO Heritage, Owens Corning Duration or GAF Timberline HDZ architectural shingle with synthetic underlayment, ice-and-water shield in valleys and full ventilation upgrade.

FAQ

Office Buildings & Professional Suites roofing FAQ

How long does an office building re-roof take?
A 30,000 sq ft Class B office runs 8–14 working days. A Class A multi-tenant tower runs 14–28 working days. Multi-building campuses are phased over 4–8 weeks. Every phase is dry-in weather-tight before crews leave site.
Can tenants stay in the building during the work?
Yes — that is the default. We provide written 7-day tenant notification templates to property management, schedule loud demo to start at 7 AM and finish before peak meeting hours, and offer after-hours/weekend windows for sensitive suites (server rooms, conference centers, executive floors).
Will you re-flash and rebuild our RTU curbs?
Yes — that is standard scope on every MBE office re-roof. New pre-formed curb caps, properly terminated membrane, code-compliant pitch pans on every penetration. HVAC outages are coordinated unit-by-unit with property management.
Will insurance cover our office building re-roof?
If the roof has qualifying hail or wind damage, your commercial property policy typically pays full replacement at like-kind-and-quality minus the deductible. Our 99% approval rate means most office buildings with documented damage replace the roof for the cost of the deductible.
Do you work with Travelers, Cincinnati, Hartford, Chubb, CNA and Hanover?
Yes — routinely. We work with every major commercial carrier.
Are your closeout documents formatted for CAM reconciliation?
Yes. Closeout documentation includes a CAM-friendly project summary suitable for triple-net lease pass-through, tenant estoppels and future property sale due diligence.
Can you provide capex-ready proposals for our committee?
Yes. Every MBE proposal is line-item and fixed-price, formatted for capex committee approval — material brand, gauge, fastener pattern, insulation R-value, tapered system design, RTU scope, flashing, copings, drains and disposal all itemized.
Does Minnesota energy code require insulation upgrade on a re-roof?
Yes — re-roof projects exceeding 50% of the existing roof area typically trigger Minnesota Commercial Energy Code (MN Rule 1323) compliance to R-30 minimum continuous roof insulation. MBE provides energy code compliance documentation.
What materials do you recommend?
60-mil or 80-mil TPO from GAF EverGuard, Carlisle Sure-Weld or Firestone/Holcim for low-slope. TAMKO Heritage, Owens Corning Duration or GAF Timberline HDZ for steep-slope architectural office buildings.
What warranty do we get?
Two warranties: (1) MBE's Lifetime Workmanship Warranty, transferable; (2) the manufacturer's NDL (no-dollar-limit) material warranty — typically 20–30 years on TPO/EPDM and 30–50 years on architectural asphalt.
Can you handle multi-building office campuses?
Yes. We phase across buildings under one PM, one schedule and one warranty. Campus-wide drone inspections are done on day one.
Are you licensed, bonded and insured?
Yes — Minnesota Class A residential and commercial license #BC691061, $2,000,000 general liability, full Minnesota workers' compensation. Certificates issued before mobilization with building owner and property management firm named as additional insured.
Do you offer financing or milestone payments?
Yes. For insurance-funded work we invoice as funds release. For ownership capex we structure milestone payments aligned to quarterly committee cycles.
How quickly can you respond after a storm?
Same-day for emergency tarping. Same-week for full inspection and adjuster meetings. Our three Twin Cities offices keep a senior PM within an hour of any office building in the metro.
How do we start the process?
