Restore confidence in your building with a commercial roof replacement done right. At Rivas Roofing, we replace aging, damaged, or failing commercial roofs with durable systems built for performance, efficiency, and long-term value. You’ll get straight answers, hands-on inspections, and workmanship we’re proud to put our name on.
Upgrade Your Building’s Roofing System
Roof replacement is the process of removing an existing roofing system and installing a brand-new one when repairs are no longer enough. This typically happens when a roof has reached the end of its service life, has widespread damage, or no longer meets performance or safety standards. Instead of patching isolated issues, replacement addresses the entire system, from insulation and underlayment to flashing and drainage, so everything works together properly.
For commercial buildings, roof replacement is about more than stopping leaks. It’s a chance to improve energy efficiency, correct flaws, upgrade materials, and ensure durability. A properly installed new roof helps manage water, withstand heat and weather exposure, and reduce ongoing maintenance issues. When done right, roof replacement provides a reliable, code-compliant system that supports your building and business for years to come.
Signs Indicating You May Need Roof Replacement:
- Persistent leaks across multiple areas, even after repeated repairs
- Widespread membrane cracking, blistering, or separation
- Saturated insulation causing soft spots or ponding water
- Excessive granule loss, exposed substrate, or deteriorated seams
- Frequent repair calls that no longer solve the underlying issues
- The roof system has reached or exceeded its expected service life
- Rising energy bills due to poor insulation or heat gain
Popular Roofing Types in Pasadena Businesses
PVC & TPO Roofing
PVC and TPO roofing are popular choices for Pasadena businesses with flat or low-slope roofs. These single-ply systems are heat-welded at the seams, creating a watertight surface that holds up well against UV exposure and high temperatures. They’re energy-efficient, low-maintenance, and ideal for office buildings, retail centers, and other commercial properties.
Metal Roofing
Metal roofing is often chosen for commercial buildings that need strength, longevity, and a clean architectural look. Standing seam and corrugated metal systems perform well in Pasadena’s sun-heavy climate because they can reflect heat and resist fire, wind, and moisture. When properly installed, metal roofs offer decades of service with minimal upkeep.
How We Handle Commercial Roof Replacement
Commercial roof replacement is a big investment, so our approach is simple: be thorough, be honest, and do it right the first time. We focus on understanding your building, your roof system, and your long-term goals before any work begins. From inspection to final walkthrough, you’ll always know what’s happening, why it matters, and what you’re getting.
Perform a Hands-on Roof Inspection
We start with a detailed, on-site inspection. We evaluate the membrane, insulation, decking, flashing, penetrations, and drainage points. Core samples may be taken to check moisture intrusion and insulation conditions. This step helps us identify system failures and structural concerns and determine if a full tear-off or partial replacement makes the most sense.
Design the Right Roofing System
Once we understand the condition of your roof, we design a system that fits your building and usage. This includes selecting the right materials, along with insulation thickness, attachment methods, and proper drainage slope. We also account for energy efficiency, local codes, and long-term durability so your new roof performs the way it should for years.
Remove and Prepare the Roof Properly
We remove the existing roofing system down to the appropriate layer, whether that’s the membrane, insulation, or deck. Damaged decking is repaired or replaced, surfaces are cleaned, and the substrate is properly prepped. This step is critical: skipping prep leads to premature failures. We ensure the foundation of your new roof is solid before installation begins.
Install and Seal Every
Detail
We install insulation, membranes, and edge systems in accordance with manufacturer specifications, paying close attention to seams, flashings, penetrations, and terminations. Seams are heat-welded or adhered correctly, drainage components are reinforced, and transitions are sealed watertight to ensure everything meets our standards.
Complete a Final Walkthrough and Inspection
After installation, we perform a final inspection to make sure every component of your new roof is installed correctly. We check seams, flashings, edges, penetrations, and drainage to confirm everything is sealed and functioning as designed. Then we walk the roof with you, explain the system, and make sure you’re confident in the work before we consider the job complete.
