Industrial-grade roof systems installed with minimal disruption to your operations. Gary manages commercial projects the same way he runs his business: personally, reliably, and on schedule.
A commercial roof failure does not just cost you repair dollars. It costs you inventory, equipment, business interruption, and tenant trust. Gary Thompson has been protecting Riverside businesses with commercial roof systems for over 35 years, and he understands that the stakes on a commercial building are fundamentally different from a residential home. Downtime is not an option. Leaks into occupied tenant spaces or over stored merchandise can escalate from a roofing problem to a liability problem overnight.
Gary works directly with building owners, property managers, and facility directors to deliver commercial roofing solutions that meet code, satisfy insurance requirements, and hold up under the punishing Inland Empire climate. He handles everything from single-tenant retail buildings to multi-unit apartment complexes, industrial warehouses, and strip malls.
Thermoplastic polyolefin is Gary's most-recommended commercial roofing membrane for Riverside buildings. Its white reflective surface meets California Title 24 energy code requirements for cool roofing, which is mandatory for most commercial reroofing projects in the state. Gary installs TPO in 60-mil and 80-mil thicknesses with fully adhered, mechanically attached, or ballasted application depending on the building's wind exposure, deck type, and foot traffic requirements. Every seam is hot-air welded on site for a permanent, watertight bond.
For warehouse, industrial, and storage buildings where reflective cooling is less critical than long-term durability, Gary installs EPDM rubber membrane systems. EPDM has the longest documented field performance of any single-ply commercial membrane, with installations still watertight after 40-plus years. It handles extreme temperature cycling, UV exposure, and building movement without cracking. Gary typically recommends EPDM for buildings with minimal HVAC loads or where the roof is not visible and aesthetics are secondary to pure performance.
Built-up roofing remains the workhorse of commercial roofing for buildings that need maximum puncture resistance and can support the weight. BUR systems consist of alternating layers of bitumen and reinforcing fabrics that create a thick, resilient membrane. Gary specifies BUR for industrial buildings, utility structures, and facilities where rooftop equipment creates concentrated loads and foot traffic is frequent. A four-ply BUR system with a gravel surface coat provides redundant waterproofing that no single-ply membrane can match.
Commercial roofs require proactive maintenance that most building owners simply do not perform until something leaks. Gary offers annual maintenance contracts that include biannual inspections, drain clearing, flashing re-sealing, and minor repair work. These contracts catch deterioration early, extend roof life by years, and create a documented maintenance history that protects property owners during warranty claims and insurance disputes. For property managers overseeing multiple buildings, Gary provides consolidated reporting and scheduling.
Commercial reroofing in California carries code requirements that do not apply to residential work. Title 24 energy standards mandate minimum reflectance and emittance values for most commercial roof replacements. Local building departments require permits, inspections, and engineering sign-off for structural modifications. Gary handles every code requirement as a standard part of his commercial scope. Permits are pulled before the first day of work, not as an afterthought. Inspections are scheduled proactively. The building owner never has to chase paperwork.
Apartment complexes, condominiums, and multi-tenant commercial buildings present logistics challenges that single-structure projects do not. Gary coordinates access through property managers, notifies tenants of work schedules, and stages materials to minimize disruption to parking and common areas. He has reroofed occupied apartment buildings while keeping every unit habitable and every tenant informed. The work happens in phases designed around occupancy, not around the fastest completion time for the crew.
Commercial roofing requires rigorous project management. Gary follows a structured process that keeps your business running while the roof gets replaced.
Gary inspects the existing system, documents damage with photos, evaluates drainage and structural conditions, and reviews HVAC equipment placement to plan around mechanical systems.
A detailed written scope covers materials, code requirements, and phased scheduling. Gary coordinates with property managers and tenants so work happens with minimal disruption to daily operations.
Crews work in planned sections to keep portions of the building protected at all times. Materials are staged to minimize parking disruption. Gary is on site daily managing quality and timeline.
Final inspection with the building department, warranty registration, and a complete project binder with photos, material specs, and maintenance guidelines delivered to the property owner.
Commercial building owners need a roofer who answers the phone, shows up when scheduled, and does not leave the property vulnerable overnight.
Gary does not hand commercial projects to a foreman and disappear. He is on your building daily during active work, personally inspecting seams, flashings, and drain tie-ins. The person who quoted the job supervises the job.
Gary phases commercial installations so your tenants stay operational, your parking stays accessible, and your building stays watertight at every stage. He schedules noisy work around your business hours when possible.
Permits, Title 24 calculations, building department inspections, and engineering sign-offs are all managed by Gary as part of the project. You never chase paperwork or coordinate with inspectors yourself.
Gary offers annual service agreements that include biannual inspections, drain clearing, re-sealing, and minor repairs. Proactive maintenance extends commercial roof life dramatically and creates the documentation trail insurers require.
Property managers with portfolios of buildings rely on Gary because he provides consolidated reporting, consistent quality, and priority scheduling across multiple properties. One call covers every building in your portfolio.
Storm damage to commercial roofs involves larger dollar amounts and more complex claims than residential. Gary documents damage systematically, communicates directly with commercial adjusters, and ensures the full scope of damage is covered.
Gary will survey your building, identify issues, and provide a written scope with honest pricing. No sales team, no high-pressure close.
Gary will survey your commercial building personally, assess the current roof condition, and deliver a detailed written scope covering materials, code requirements, scheduling, and pricing. No obligation, no sales pressure.
