Commercial Roofing Systems: Duro-Last PVC, Metal & Coatings
Matched to the building: deck type, slope, what is happening under the roof, and how long you need it to last. We are a Duro-Last Platinum contractor and a metal fabricator — so we can recommend the right one without a bias toward either.
Commercial roofing systems we install
Five systems, one standard of installation.
Low-slope Duro-Last PVC is most of what we do. The rest covers the sloped, metal and coat-over cases a commercial building also throws at you.
- Duro-Last PVC single-ply (low slope)
- Prefabricated to your roof's measurements; most seams welded in a controlled plant. Resists grease, chemicals and ponding; highly reflective. 15- and 20-year NDL warranties. Ideal for food processing, manufacturing and warehousing.
- Metal retrofit
- Flute-fill insulation and a new single-ply membrane over your existing metal roof. Stops leaks at every fastener, adds R-value, no tear-off, no interruption.
- Metal roofing — R-panel & standing seam
- Standing-seam panels roll-formed on site to exact length; R-panel for pre-engineered and agricultural buildings. Sloped roofs, canopies, mansards and wall cladding.
- Commercial shingle roofing
- Architectural asphalt shingles for steep-slope sections — offices, clubhouses, churches and multi-building campuses that mix slopes.
- Acrylic & silicone coatings
- Fluid-applied restoration over sound existing roofs: seals seams and fasteners, adds reflectivity, and buys years before a replacement.
Roofing systems in the field
Three systems, three buildings.
A metal retrofit over a store roof, a tan Duro-Last membrane tied into a shingle roof, and a white Duro-Last roof after a hail claim.
How we choose a roofing system
How we pick.
Core cuts and a moisture survey first. Then: what runs under the roof (grease, chemicals, steam), the deck and its load capacity, slope and drainage, access, and how long you plan to own the building. The recommendation comes with the reasoning written down.
Commercial Roofing Systems Questions
Why Duro-Last?
Prefabrication. Up to 85% of seams are welded in the factory rather than on your roof, which is where most single-ply failures start. Our 2001–2006 Duro-Last roofs are 92% still in service as of 2026.
Can you go over my existing metal roof?
Usually, yes. A metal retrofit adds insulation and a new membrane over the existing panels without tear-off or interruption to operations.
Will you do work on TPO, EPDM, modified bitumen, ballasted roofs and built-up roofs?
Yes. We frequently repair and maintain those roof types. We can replace or go over top of them too, but we'll typically use Duro-Last PVC to do it.
