# Low-Slope Roof Systems > Low-slope commercial roof systems in Spokane, WA: TPO, EPDM, PVC, KEE, and built-up options, and how to choose between repair and replacement. Canonical: https://commercialroofersspokane.com/roof-systems Roof System ## System recommendations are tied to deck type, insulation, wind exposure, freeze-thaw cycles, rooftop equipment, and whether the existing assembly can be repaired, restored, recovered, or replaced. The right system follows from the deck, insulation, wind exposure, and freeze-thaw cycling on the building. Roof System ### [Black EPDM in Spokane](https://commercialroofersspokane.com/roof-systems/black-epdm) Black EPDM is a proven rubber membrane that flexes through hard freeze-thaw cycling, and its heat-absorbing surface can actually help shed snow on Spokane roofs where winter performance matters more than summer reflectivity.

[Open Scope](https://commercialroofersspokane.com/roof-systems/built-up-asphalt) Roof System ### [Fleeceback TPO in Spokane](https://commercialroofersspokane.com/roof-systems/fleeceback-tpo) Fleeceback TPO bonds a fabric backing to the membrane for puncture resistance and a strong adhered bond, making it a tough, reflective choice for Spokane roofs that face hail, foot traffic, and high wind uplift. [Open Scope](https://commercialroofersspokane.com/roof-systems/fleeceback-tpo) Roof System ### [KEE Membrane in Spokane](https://commercialroofersspokane.com/roof-systems/kee-membrane) KEE membranes hold their plasticizers far longer than standard single-ply, resisting the grease and UV that age ordinary sheets, which makes them a durable fit for Spokane restaurants and plants under strong summer sun. [Open Scope](https://commercialroofersspokane.com/roof-systems/kee-membrane) Roof System ### [Modified Bitumen APP in Spokane](https://commercialroofersspokane.com/roof-systems/modified-bitumen-app) APP modified bitumen is torch- or mop-applied into a rugged, UV-stable membrane, a redundant multi-ply system well suited to Spokane low-slope roofs that take regular service traffic and the region's summer heat. [Open Scope](https://commercialroofersspokane.com/roof-systems/modified-bitumen-app) Roof System ### [Modified Bitumen SBS in Spokane](https://commercialroofersspokane.com/roof-systems/modified-bitumen-sbs) SBS modified bitumen stays flexible in the cold thanks to its rubber modifiers, giving it the crack resistance Spokane's deep-freeze winters demand in a tough, redundant multi-ply low-slope assembly. [Open Scope](https://commercialroofersspokane.com/roof-systems/modified-bitumen-sbs) Roof System ### [PVC Membrane in Spokane](https://commercialroofersspokane.com/roof-systems/pvc-membrane) PVC's hot-air-welded seams create one of the most watertight and chemical-resistant single-ply systems available, a strong fit for Spokane buildings venting grease or chemicals where seam integrity is non-negotiable. [Open Scope](https://commercialroofersspokane.com/roof-systems/pvc-membrane) Roof System ### [Spray Polyurethane Foam in Spokane](https://commercialroofersspokane.com/roof-systems/spray-polyurethane-foam) Spray polyurethane foam delivers insulation and a seamless waterproof layer in one application, self-flashing around penetrations, which makes it ideal for irregular Spokane roofs fighting heat loss through long winters. [Open Scope](https://commercialroofersspokane.com/roof-systems/spray-polyurethane-foam) Roof System ### [Standing Seam Metal in Spokane](https://commercialroofersspokane.com/roof-systems/standing-seam-metal) Standing seam metal hides its fasteners and lets panels expand and contract freely, shedding snow cleanly and lasting decades, which suits Spokane buildings that face heavy winter accumulation and hard freeze-thaw swings. [Open Scope](https://commercialroofersspokane.com/roof-systems/standing-seam-metal) Roof System ### [TPO 60 Mil in Spokane](https://commercialroofersspokane.com/roof-systems/tpo-60-mil) Standard 60-mil TPO offers a reflective, weldable membrane at a sensible price point, a practical default for Spokane low-slope roofs where the budget favors a proven single-ply over a heavier-gauge upgrade. [Open Scope](https://commercialroofersspokane.com/roof-systems/tpo-60-mil) Roof System ### [TPO 80 Mil in Spokane](https://commercialroofersspokane.com/roof-systems/tpo-80-mil) At 80 mil, TPO adds extra thickness for puncture resistance and a longer service life, worth the upgrade on Spokane roofs that carry frequent foot traffic, rooftop equipment, and the abrasion of winter ice removal. [Open Scope](https://commercialroofersspokane.com/roof-systems/tpo-80-mil) Roof System ### [White EPDM in Spokane](https://commercialroofersspokane.com/roof-systems/white-epdm) White EPDM pairs rubber's freeze-thaw flexibility with a reflective surface, a niche choice for Spokane roofs that want EPDM's cold-weather durability alongside reduced summer heat gain under the region's intense sun.
