Warning Signs
Signs Your Commercial Roof Needs Attention
- Standing water or ponding after rain
- Interior leaks or ceiling water stains
- Blistering, bubbling, or cracked membrane
- Failed or deteriorating roof seams
- HVAC unit penetration leaks
- Visible cracks or splits in flat roof surface
Catching problems early saves money. Small membrane cracks and failed seams are inexpensive to fix. Left alone, they become full-replacement jobs.

What We Provide
Commercial Roof Repair, Replacement & Inspection
Property managers and owners hire PRC 13 for commercial roofing services when flat or low-slope systems need diagnosis, focused repair, or a planned replacement—not a one-size residential approach.
Commercial Roof Repair
Hire commercial roof repair here for leak diagnosis, seam and membrane repairs, flashing fixes, and penetration work when the rest of the system still has service life—including commercial roof leaks on flat and low-slope roofs.
Commercial Roof Replacement
Full-system replacement of failed flat or low-slope roofs, with a written scope, a materials plan for TPO, EPDM, modified bitumen, or built-up when that system fits, and a schedule around occupied buildings.
Commercial Roof Inspection
Documented commercial roof inspection of membrane condition, drainage and ponding, seams, flashings, and HVAC penetrations before any repair or replacement decision.
Roof Systems
Flat & Low-Slope Systems We Work On
Commercial and light-commercial buildings in the Sacramento area commonly use these membranes. We inspect the system you have, then recommend commercial roof repair or replacement based on condition—not a default product pitch. Comparing membranes? Read TPO vs EPDM.
TPO Roofing
Thermoplastic membrane often chosen for reflectivity and welded seams on flat and low-slope commercial roofs.
EPDM Roofing
Rubber membrane systems common on low-slope buildings. We inspect seams, flashings, and penetrations before recommending repair or replacement.
Modified Bitumen
Multi-layer modified systems used on many Sacramento-area commercial and light-commercial roofs. We evaluate existing layers, drainage, and flashings before scoping repair or replacement.
Built-Up Roofing
Traditional layered asphalt systems. We evaluate existing plies, drainage, and flashings before scoping repair or replacement.
Repair vs Replacement
How We Decide What a Commercial Roof Needs
Leak diagnosis starts with where water enters—seams, flashings, HVAC curbs, drains—not only where it shows up indoors. Localized membrane or seam failures can often be repaired when the surrounding field still has life.
Widespread membrane failure, repeated leaks across the field, failed drainage that keeps ponding, or an end-of-life system usually points toward commercial roof replacement planning after a documented inspection.
Residential flat-roof leaks that are not a commercial hire still belong on roof repair or a roof inspection first. Occupied commercial buildings get the same honesty with scheduling that protects operations.
Inspection findings drive the scope
Membrane condition, seams, drainage, and penetrations are documented before any repair or replacement recommendation.
Repair when the system still works
Focused commercial roof repair stops active leaks without tearing off a roof that still has useful life.
Replace when the field is done
End-of-life membranes and chronic ponding get a written replacement plan timed around your tenants or business hours.

Our Work
Flat & Low-Slope Roof Projects
Three gallery records show PRC 13 flat-roof work. None of them records a city or a membrane product name. One is a completed flat roof restoration. The other two show a crew installing a flat roof membrane, including a white membrane in the wide view and a closer installation detail.

Common Questions
Commercial Roofing FAQs
We work on flat and low-slope commercial roofs, including TPO, EPDM, modified bitumen, and built-up systems. PRC 13 primarily serves small to mid-size commercial properties in the Sacramento area.
Ponding water after rain, interior leaks or ceiling stains, blistering or cracked membrane, failed seams, and leaks around HVAC penetrations are common warning signs. Schedule an inspection when any of these appear rather than waiting for the next storm.
Many properties benefit from at least an annual inspection, plus checks after major storms. High-traffic roofs, older membranes, or buildings with past leaks may need more frequent reviews. PRC 13 can recommend a cadence after seeing the roof.
System type, roof size, membrane condition, insulation and deck findings, drainage corrections, and how much disruption the schedule requires all affect cost. We provide a written scope after inspection rather than a generic published rate.
Yes. We can schedule commercial roofing work before or after business hours, or on weekends when needed, to reduce disruption to operations.
Yes. We document storm damage and can work alongside your commercial insurance adjuster. Coverage decisions remain with the insurer.
That is what the inspection is for. We document what can be repaired and what has reached end of life. We do not push replacement when a focused repair is sufficient.
Timeline depends on roof size and system type. Smaller commercial roofs are often completed in a few days; larger jobs are scoped with a firm schedule before work begins.
