Commercial Roofing
& Repair Services

Common indicators include ponding water that lingers more than 48 hours after rain, visible seam separation on TPO or EPDM membranes, lifted flashing at parapet walls or equipment curbs, cracked pipe boot seals, clogged or slow-draining scuppers and drains, interior water stains, and loose or damaged rooftop penetration seals. Many Minnesota commercial roof failures start silently — a small flashing gap or seam separation that only becomes visible inside weeks later. Exteriors Plus provides written condition reports with photo documentation on every maintenance visit, catching these issues while they’re still minor repairs. If your property hasn’t had a professional inspection in the last 12 months, scheduling one is the simplest way to know where your roof actually stands.

Preventative maintenance programs typically run $0.03–$0.08 per square foot annually, depending on roof system, size, access requirements, and visit frequency. On a 20,000 sq ft building, that’s roughly $600–$1,600 per year to protect an asset that costs $100,000–$240,000 to replace. Emergency commercial roof repairs typically cost $2,000–$8,000 per incident, not including interior damage. Exteriors Plus provides free baseline inspections and written quotes for Twin Cities commercial properties — no charge, no obligation. Our plans include biannual inspections, minor on-site repairs, debris clearing, drain cleaning, and post-storm evaluations. We’ll walk your roof, review your warranty, and give you a transparent quote based on what your specific property actually needs.

Industry standard is twice per year minimum — spring after freeze-thaw cycles have stressed the membrane and flashings, and fall before winter load and ice dam conditions arrive. Additional inspections are recommended after major storms, hail events, or any rooftop service work by HVAC or other trades. Minnesota’s climate makes biannual inspections especially important because freeze-thaw damage, ice dam stress, and hail exposure are cumulative year over year. Most manufacturer warranties on TPO, EPDM, and modified bitumen systems require documented inspections at specific intervals — skipping them can void coverage. Exteriors Plus tracks your inspection schedule, provides post-storm evaluations when needed, and maintains the documentation your warranty and insurance may require.

Most commercial roof issues are repairable when caught early. Heat-welded seam separations on TPO, adhesive failures on EPDM, flashing issues at penetrations, and isolated membrane punctures can all be addressed without replacement. Extensive membrane shrinkage across a large EPDM field, widespread seam failure on aging TPO, or saturated insulation underneath the membrane often indicates replacement is more cost-effective. Exteriors Plus inspects seam integrity, membrane condition, drainage, and penetration seals on every visit and gives you an honest assessment of remaining useful life. Many commercial systems get a 25–30% life extension from routine maintenance alone — meaning replacement can often be planned on your timeline and budget rather than forced by an emergency.

Exteriors Plus stands behind all commercial maintenance and repair work with warranties appropriate to the scope — and as a GAF Certified contractor licensed in Minnesota (MN LIC#BC637312), our work supports manufacturer warranty compliance on covered systems. This matters because nearly every TPO, EPDM, and single-ply warranty requires documented inspections and repairs by certified contractors. Unauthorized work or undocumented maintenance can void coverage you’ve already paid for. Our written condition reports, photo documentation, and invoice records give property managers and building owners the paper trail warranties typically require. We’ll review your existing warranty terms as part of your baseline inspection and confirm exactly what’s required to keep your coverage intact.

Yes. Storm damage, active leaks over occupied or high-value space, and post-hail emergencies require fast response to prevent secondary damage to interiors, inventory, equipment, and tenants. Exteriors Plus offers same-day inspections when commercial clients need them and prioritizes emergency response for properties on our maintenance programs. Our team has extensive experience with storm damage assessment and emergency repair across Savage, Minneapolis, St. Paul, and the Twin Cities metro. When you call, we’ll assess the situation, implement a temporary weather-tight fix to stop further damage, and develop a permanent repair plan. Property managers on our maintenance programs receive priority scheduling for emergency response — one of the tangible benefits of a structured program.

Exteriors Plus maintains the full range of commercial roofing systems common across the Twin Cities metro, including TPO (Thermoplastic Polyolefin), EPDM (rubber membrane), modified bitumen, built-up roofing, and metal systems. TPO is our most common commercial maintenance system — valued for energy efficiency and freeze-thaw durability, with most failures occurring at heat-welded seams, parapet flashing, and equipment curb penetrations. EPDM performs well in cold climates but is vulnerable to seam adhesive failure and shrinkage over time. Our inspections are tailored to the specific system, not a generic checklist — seam integrity checks for TPO, adhesive and shrinkage inspections for EPDM, coping and flashing reviews for modified bitumen, and fastener and panel condition on metal roofs.

Effective commercial leak repair requires identifying the entry point, not just the symptom — which is often several feet away from where water appears inside. Approximately 80% of commercial roof leaks originate at penetrations: HVAC curbs, vent pipes, skylights, drains, and parapet flashings. Exteriors Plus traces leaks to the actual source, repairs the underlying failure, and documents the fix with photos and written reports. We also identify secondary conditions — saturated insulation, compromised decking, adjacent seam weaknesses — that could cause the same leak to return in a new location. Our maintenance program catches the conditions that cause leaks before water ever makes it inside, which is the only reliable way to prevent recurrence.

Yes. Exteriors Plus is licensed in Minnesota (MN LIC#BC637312), GAF Certified, and carries full liability and workers compensation coverage for all commercial roofing work. Our technicians follow OSHA fall protection standards, manufacturer-specific installation procedures, and all applicable Minnesota building codes. For commercial property owners and managers, this matters — uninsured or unlicensed contractors expose your property to liability for workplace injuries, substandard work that voids warranties, and insurance claim denials. We provide certificates of insurance and license documentation on request for any commercial project. Our commitment to proper licensing, certification, and insurance reflects our dedication to professional standards and client protection across every Twin Cities commercial property we service.

Our commercial inspections examine every component likely to fail first on a flat or low-slope roof. We check seams and laps for separation or adhesive failure, flashing at every penetration (HVAC curbs, pipes, vents, skylights), drainage performance at all drains and scuppers, membrane condition for punctures or UV degradation, parapet walls and coping, and damage from rooftop foot traffic. Aerial drone inspection is included on Gold and Platinum plans for larger or hard-to-access roofs. Every visit produces a written condition report with photographs — suitable for building owners, property managers, insurance documentation, and warranty compliance. We don’t do 15-minute walkthroughs. A proper commercial inspection takes the time required to actually assess the roof.

Yes. Exteriors Plus provides the documentation commercial insurance claims require: detailed damage assessments, dated photographs, written condition reports, and professional estimates suitable for adjuster review. Minnesota’s hail and wind activity drives significant commercial insurance claims every year, and the difference between a paid claim and a denied one is usually documentation quality. Our maintenance program creates an ongoing record of roof condition — so when a storm hits, we can clearly demonstrate what was pre-existing versus what’s storm damage. We communicate directly with adjusters during claim reviews and provide the technical detail that commercial claims typically require. While we don’t handle claim negotiations, our documentation consistently gives property managers a strong foundation for successful claims.

Nearly every TPO, EPDM, and single-ply commercial warranty includes a maintenance requirement — typically documented biannual inspections performed by certified contractors. Skip the inspections and you risk voiding the warranty, meaning a manufacturing defect the manufacturer should cover becomes your expense. Unauthorized repairs by non-certified contractors can also void coverage. Exteriors Plus is GAF Certified and maintains the documentation, photo records, and invoices your warranty administrator may request during a claim. As part of your baseline inspection, we review your existing warranty terms so you know exactly what’s required to keep your coverage active. For many commercial property owners, this alone is worth more than the cost of the maintenance program.

Yes. Exteriors Plus offers three tiers of maintenance programs — Silver, Gold, and Platinum — structured around property type, roof size, and building use. All plans include annual or semi-annual inspections, priority emergency service, repair discounts, and documented condition reports. Gold and Platinum plans add aerial drone inspection, post-storm evaluations, and spot-seal of minor leaks at no additional charge. Commercial pricing is quoted per property because commercial roofs vary so significantly in size, system type, access, and complexity. Preventative maintenance typically costs 2–3x less than reactive repairs over a roof’s lifetime and extends serviceable life by 25–30%. For most Twin Cities commercial property owners, a structured program is the single highest-ROI decision in the building’s operating budget.

We’re insurance claim specialists, GAF certified, and offer same-day inspections when commercial clients need them. We serve Savage, Minneapolis, St. Paul, Eden Prairie, Burnsville, Lakeville, and the broader Twin Cities metro with local responsiveness you won’t get from out-of-state storm chasers. Most importantly, we give honest assessments — we’ll tell you when a roof can be maintained for another five years rather than pushing replacement.
