One white sheet on top. Seven layers doing the work.
When a flat roof leaks, the real question is which layer failed. A bad seam is a repair. Wet insulation underneath can mean a new roof. Watch it come apart in 12 seconds.

Get back up to $2.56 million Section 179 for your commercial roof
For 2026 the Section 179 expensing limit is $2,560,000. Roofs on nonresidential buildings (offices, retail, warehouses, restaurants) can count as "qualified real property." That can mean expensing the roof in the year it goes on, not depreciating it over 39 years.
2026 limit $2,560,000; reduction begins once total qualifying purchases exceed $4,090,000 (IRS Rev. Proc. 2025-32). Roofs qualify as "qualified real property" only for improvements to nonresidential real property (IRC §179(e)–(f)); apartments and other residential rental buildings generally do not qualify. The deduction is also limited to your business taxable income. Repair King is a roofing contractor, not a tax advisor. This is not tax advice, so confirm with your CPA before you sign.
One contractor, clear reports, no chasing.
Property managers tell us the hardest part is getting a contractor to show up and communicate. We send photos, give straight timelines and keep you updated until the job is closed out.

Price vs. how long it lasts
One $ = lowest price. $$$$ = highest price. The bar shows how many years each flat roof system usually lasts.
$ = relative upfront cost; your real price depends on roof size, insulation, tear-off, drainage and access. Years = typical service life with proper install and maintenance (industry ranges; sources in the comparison table below), not a warranty or a promise.
Which flat roof system does my building actually need?
Pick your building and what matters most. You'll get a straight recommendation between PVC, TPO, EPDM, modified bitumen, built-up and coatings, and the reason why. Then we confirm it on your roof, for free.
Minnesota twist: the Twin Cities average 107 days a year that never get above 40°F, and 40°F is the installation minimum many flat-roof products list (Duro-Last PVC, SBS cap sheets, silicone coatings; sources ², ⁶, ⁸). Get your assessment done while there's still a warm-season window to install.
Book Before the Cold WindowTPO, PVC, EPDM… what's the real difference for my roof?
The honest version, in one table. More filled dots = better at that job.
| System | Typical life | Upfront cost | Grease & chemicals | Energy (white) | Seams | MN cold | Best for |
|---|---|---|---|---|---|---|---|
| PVCincl. Duro-Last, what we install | 25–35 yrs | $$$$ | Excellent: resists animal fats, grease, many chemicals ¹ | Heat-welded; Duro-Last up to 85% factory-welded ² | Good. Duro-Last installs at 40–115°F ² | Restaurants, grocery, hospitals & labs, schools | |
| TPOthermoplastic polyolefin | 20–30 yrs | $$$$ | Fair: can absorb grease and oils ³ | Heat-welded on the roof | Good; plan installs in the warm season | Warehouses, offices, budget white roofs | |
| EPDMblack rubber | 20–30 yrs | $$$$ | Poor: don't vent animal fats or oils onto EPDM ⁴ | Taped / adhered laps | Excellent cold flexibility ⁵ | Big, simple warehouse roofs on a budget | |
| Modified bitumenSBS, 2–3 plies | 20–25 yrs | $$$$ | Fair | Torched, mopped or self-adhered laps | Very good: SBS cap rated flexible to 0°F ⁶ | Small roofs, heavy foot traffic, rooftop decks | |
| Built-up (BUR)tar & gravel, 3–4 plies | 20–30 yrs · Twin Cities schools avg ~25 ⁷ | $$$$ | Fair | Continuous multi-ply, no single-ply seams | Proven on Twin Cities schools ⁷ | Schools & institutions built for the weight | |
| Coating / restorationsilicone or acrylic over your roof | Adds 10, 15 or 20 yrs (warranty terms) ⁸ | $$$$ | Varies by coating | Seamless over the existing roof | Apply only above ~40°F ⁸ | Sound, dry roofs; moisture survey first ⁹ |
Kitchen exhaust, grease traps, rooftop units: that's where flat roofs fail first.
On restaurant and food-service roofs we look hardest at the fan curbs and the path the grease takes. Even PVC should be cleaned of grease regularly ⁴, so we'll also talk about walk pads and grease containment.

What homeowners say.
As a property manager, I've worked with many other companies but their professionalism, timeliness, service and everything was great! I will keep using them.
Our new roof looks fantastic, and more importantly, we no longer have to worry about leaks! They are reliable, trustworthy, and deliver top-notch quality.
Mike came to do an assessment. He caught concerns others had missed. He was professional and polite but very kind. I would recommend him 100%.
Why we install Duro-Last on commercial flat roofs.
Duro-Last is a reinforced PVC membrane that is custom-fabricated to each building's measurements in a factory, then installed by our crews. It's on the Bloomington Lincoln dealership, the Forest Lake Chrysler Jeep Dodge dealership, HOPE Community Academy in St. Paul, The Marketplace in Cokato and the Coyote Moon Grille clubhouse in St. Cloud. These are the reasons owners pick it.
Seams welded in the factory
Up to 85% of seams are made in a controlled factory, not on a windy roof. On a 50,000 sq ft roof that's under 1,300 ft of rooftop seaming versus 7,500+ ft with rolled goods.
Solar reflectance, white membrane
CRRC-rated and ENERGY STAR qualified when new. A cooler roof in July for buildings with refrigeration, server rooms or big glass showrooms.
Grease & chemical resistant
Built to resist many oils and chemicals, the reason PVC is the usual pick for restaurants, grocery stores and industrial exhaust.
Hot-tar kettles
Quiet, flame-free installation with no fumes. Dealerships, schools, stores and hotels stay open while we work overhead.
Fire & wind approvals
PVC self-extinguishes once the flame source is removed. The system carries UL and FM approvals and is NSF/ANSI 347 Platinum certified.
Year warranty options
Duro-Last offers manufacturer warranties from 15 to 30 years, including hail and high-wind options on qualifying commercial installations. We'll walk you through what applies to your building.
