Extend the life of your commercial roof without tearing it off. Rivas Roofing restores aging systems using high-performance liquid-applied systems (LAS) that seal seams, stop leaks, and improve reflectivity. We evaluate your roof in person and apply coatings precisely, giving Pasadena-area buildings a cost-effective, long-lasting upgrade you can trust today.
Extend Roof Life Without
Full Replacement
Roof restoration and coatings extend the life of a commercial roof without a replacement. Instead of tearing everything off, liquid-applied systems (LAS) are installed over the existing membrane. These coatings help create a seamless, fully adhered layer that seals cracks, reinforces weak areas, and restores waterproofing performance across the entire roof surface.
Roof restoration is often used when the structure is sound but aging, weathered, or leaking at seams and penetrations. Coatings can be acrylic, silicone, or polyurethane, each chosen based on slope, drainage, and exposure. When applied correctly, LAS systems can improve reflectivity, reduce heat gain, and help extend service life while minimizing disruption to your business. It’s a smart option for many low-slope commercial roofs when conditions and existing materials allow.
Signs Indicating You May Need Roof Restoration & Coatings:
- Recurring leaks at seams or penetrations that keep coming back after basic repairs
- Widespread surface cracking or membrane wear but the roof structure is still solid
- Aging commercial roof nearing the end of its warranty yet not failing system-wide
- Water ponding on low-slope areas causing faster material breakdown over time
- Rising cooling costs due to poor reflectivity and heat absorption
- Blistering, peeling, or exposed substrate on the existing roof membrane
- Frequent patchwork repairs that are no longer cost-effective long term
How We Handle Commercial Roof
Restoration & Coatings
Roof restoration only works when it’s done methodically. Our approach is hands-on, detail-driven, and tailored to how your building actually performs day to day. We evaluate whether restoration makes sense, choose the right system, and install it the right way.
Perform a Full Roof Inspection and Moisture Evaluation
We start by walking the entire roof surface, checking membrane condition, seams, flashings, penetrations, drains, and ponding areas. We look for saturated insulation, trapped moisture, and structural issues that would disqualify the property for restoration. If needed, we perform core cuts or infrared scanning. This confirms whether a liquid-applied system is appropriate and helps us define prep requirements, coating type, and thickness before any work begins.
Prepare the Existing Roof for Proper Adhesion
We power-wash to remove dirt, oils, and loose material, then address all defects before coatings are applied. That includes reinforcing seams with polyester fabric, repairing blisters, tightening fasteners, and sealing penetrations with compatible mastics. Any wet insulation or deteriorated sections are removed and replaced so the coating system bonds to a clean, stable substrate.
Apply the Liquid-Applied Coating System
Once prepped, we install the selected coating (acrylic, silicone, or polyurethane) based on slope, drainage, and exposure. Coatings are applied at manufacturer-specified mil thickness using rollers or spray equipment to ensure optimal coverage. We detail edges, seams, and penetrations first, then coat the roof field to create a seamless, waterproof membrane.
Complete Final Inspection and Performance Check
After application, we inspect the entire system to confirm uniform coverage, proper thickness, and clean detailing. We verify that drains and scuppers are clear and review cure times before the roof is put back into service. You’ll get a clear breakdown of the installed system, including maintenance expectations and how to maximize the lifespan of your restored roof.
