# Low-slope and commercial roof systems > System pages compare how membranes, coatings, metal assemblies, insulation, attachment, drainage, and warranty paths affect commercial roof decisions. Canonical: https://commercialroofinglexington.com/roof-systems System pages compare how membranes, coatings, metal assemblies, insulation, attachment, drainage, and warranty paths affect commercial roof decisions. System pages compare how membranes, coatings, metal assemblies, insulation, attachment, drainage, and warranty paths affect commercial roof decisions. The same process is used across Lexington commercial buildings: confirm the condition, protect the building, and make the next roof decision visible before work begins.

Lexington owners get a written, roof-specific recommendation that accounts for local weather, rooftop equipment, occupied areas, access, and the cost drivers that can change a roof budget. ## Inspect Considerations Access Drainage Membrane Flashing Moisture Budget Schedule Close-In Separate temporary control, permanent repair, maintenance, coating, recover, and replacement paths. Lexington owners get a written, roof-specific recommendation that accounts for local weather, rooftop equipment, occupied areas, access, and the cost drivers that can change a roof budget. ## Plan Considerations Access Drainage Membrane Flashing Moisture Budget Schedule Close-In Stage roof work around weather windows, building operations, tenant routes, and close-in requirements.

[View Scope](https://commercialroofinglexington.com/roof-systems/built-up-asphalt-roofs) ## [EPDM Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/epdm-roof-systems) EPDM rubber membranes age predictably over Lexington flat roofs, so we re-adhere shrinking sheets, reseal the seams that cold splits open, and tell you honestly when the membrane is past restoration. [View Scope](https://commercialroofinglexington.com/roof-systems/epdm-roof-systems) ## [Fleeceback TPO Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/fleeceback-tpo-roof-systems) The fleece backing on fleeceback TPO adds puncture resistance and lets it be fully adhered over uneven decks, a durable choice for Lexington buildings where foot traffic and wind uplift are both concerns. [View Scope](https://commercialroofinglexington.com/roof-systems/fleeceback-tpo-roof-systems) ## [KEE Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/kee-roof-systems) KEE membranes keep their plasticizers far longer than standard PVC, which is why Lexington restaurants and chemical-exposed plants choose them; we install and weld-repair them to outlast ordinary single-ply. [View Scope](https://commercialroofinglexington.com/roof-systems/kee-roof-systems) ## [Modified Bitumen App in Lexington, KY](https://commercialroofinglexington.com/roof-systems/modified-bitumen-app) APP modified bitumen carries a tough, heat-welded surface suited to foot-trafficked Lexington roofs; we install and repair the granule loss and seam openings that the region's UV and temperature swings cause. [View Scope](https://commercialroofinglexington.com/roof-systems/modified-bitumen-app) ## [Modified Bitumen SBS in Lexington, KY](https://commercialroofinglexington.com/roof-systems/modified-bitumen-sbs) SBS modified bitumen stays flexible in cold, an advantage through Kentucky winters, so we use it where freeze-thaw movement would crack a stiffer membrane and repair the base-flashing splits that still develop. [View Scope](https://commercialroofinglexington.com/roof-systems/modified-bitumen-sbs) ## [PVC Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/pvc-roof-systems) Hot-air-welded PVC forms seams stronger than the membrane itself and resists grease and chemicals, making it a top pick for Lexington kitchens and labs; we install, probe-test, and weld-repair these roofs. [View Scope](https://commercialroofinglexington.com/roof-systems/pvc-roof-systems) ## [Silicone Roof Coating Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/silicone-roof-coating-systems) A silicone restoration coating seals a weathered but sound roof and shrugs off the ponding that plagues flat Lexington decks, extending service life and reflecting summer heat without a full tear-off. [View Scope](https://commercialroofinglexington.com/roof-systems/silicone-roof-coating-systems) ## [Standing Seam Metal Roofs in Lexington, KY](https://commercialroofinglexington.com/roof-systems/standing-seam-metal-roofs) Concealed-clip standing-seam panels expand and contract through Kentucky's temperature swings without backing out fasteners, so we install and repair them where exposed-fastener metal would leak within seasons. [View Scope](https://commercialroofinglexington.com/roof-systems/standing-seam-metal-roofs) ## [TPO 60 Mil Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/tpo-60-mil-roof-systems) Sixty-mil TPO is the workhorse white membrane for Lexington commercial roofs, balancing cost and durability; we install it with probe-tested welds and repair the seams that decide how long it actually lasts. [View Scope](https://commercialroofinglexington.com/roof-systems/tpo-60-mil-roof-systems) ## [TPO 80 Mil Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/tpo-80-mil-roof-systems) Eighty-mil TPO adds thickness and puncture resistance for Lexington roofs with heavy foot traffic or hail exposure, and we install and repair it where the extra membrane buys real added service life. [View Scope](https://commercialroofinglexington.com/roof-systems/tpo-80-mil-roof-systems) ## [TPO Roof Systems in Lexington, KY](https://commercialroofinglexington.com/roof-systems/tpo-roof-systems) Reflective white TPO is the default new flat roof across Lexington, but weld quality determines its lifespan, so we install and probe-test seams and repair the laps that separate as the membrane ages.
