Commercial & Low-Slope
PVC, single-ply, membrane, cold-process, and cap-sheet roofing — suitable for commercial and low-slope applications.
Commercial Roofing
Commercial and low-slope roofs call for different systems than a residential pitched roof. Raptis Roofing installs, repairs, and maintains PVC, TPO, EPDM, and cold-process cap-sheet roofing systems for offices, retail properties, warehouses, and other commercial buildings in Merced and the surrounding area.

Why Systems Differ
A low-slope or flat commercial roof doesn't shed water the way a pitched residential roof does, which is why it needs a membrane system engineered for it — PVC, TPO, EPDM, or a cold-applied cap-sheet system — rather than tile or shingle. Ponding water, membrane punctures, and failed seams are the most common points of failure, and they're usually catchable before they become a full leak if the roof gets checked regularly.
Ongoing Maintenance
Commercial roofs represent a real capital investment, and membrane systems generally respond well to maintenance — seam repairs, flashing touch-ups, and drainage checks can extend a roof's service life well past what it would get with no attention at all. For property managers handling multiple buildings, staying ahead of small repairs is usually cheaper than an emergency replacement later.
FAQ
PVC, TPO, EPDM, and cold-process cap-sheet systems are all common choices for low-slope commercial roofs — the right one depends on the building, budget, and existing roof condition.
Commercial roofs generally benefit from at least an annual inspection, plus a check after major storms, to catch membrane damage or ponding water early.
Often, yes — membrane seam repairs, flashing repairs, and leak detection can extend the life of a commercial roof before a full replacement is necessary.
