About This Service
Commercial Roofing Requires a Different Level of Expertise
A commercial roofing project is not simply a larger version of a residential job. The structural loading requirements differ. The drainage design is more complex. The membrane systems used on flat and low-slope commercial roofs are entirely different from pitched residential shingle systems. The code compliance documentation requirements are more rigorous, and the consequences of an error or inadequate installation are more far-reaching because of the scale of the building and the business operations conducted beneath the roof.
Rivendale Roofing Service has dedicated commercial roofing capacity in Lake Shastina, CA with teams trained specifically in commercial membrane systems, large-scale project coordination, and the documentation requirements of commercial property management. We work with building owners, property managers, facilities directors, and general contractors to deliver roofing projects that meet every technical, code, and schedule requirement.
Our commercial division handles projects ranging from small retail strip centers and single-building warehouses to multi-building industrial campuses and large-format commercial complexes. Every project receives a dedicated project manager, detailed pre-installation planning, and formal completion documentation including all warranty registrations and as-built records.
Commercial Roofing Systems We Install and Maintain
We install and service the full range of commercial roofing systems approved for use in Lake Shastina, CA. Each system recommendation is based on your building's specific slope, structural capacity, drainage design, and performance requirements.
TPO Single-Ply Membrane
Thermoplastic polyolefin is the most widely specified commercial roofing membrane for new construction and replacement projects. TPO offers excellent heat-weld seam strength, superior UV resistance, and energy-efficient white reflective surfaces that reduce cooling loads. We install TPO in fully adhered, mechanically fastened, and ballasted configurations.
EPDM Rubber Membrane
Ethylene propylene diene monomer provides exceptional flexibility in extreme temperature ranges, making it an excellent choice for buildings in climates with wide seasonal temperature variation. EPDM has a long performance track record in commercial applications and is available in both black and white-coated versions for heat management.
Modified Bitumen Systems
Modified bitumen roofing provides a robust multi-ply system with excellent puncture resistance and the long installation track record of asphaltic roofing. We install APP torch-applied and SBS cold-adhesive systems appropriate to the structural and thermal requirements of each commercial building, including systems approved for rooftop equipment zones.
Built-Up Roofing (BUR)
Traditional built-up roofing remains appropriate for certain commercial applications where its multi-ply redundancy and ballasted installation provide the structural performance required. We install BUR systems using hot-mopped asphalt or cold-process adhesive methods with appropriate ply counts and surfacing materials for the specified exposure conditions.
Spray Polyurethane Foam
SPF roofing is a seamless insulation and weatherproofing system applied as a liquid that expands and hardens into a continuous insulating layer. It is particularly effective for re-roofing over irregular or complex existing surfaces and delivers exceptional thermal performance. We apply SPF systems with compatible protective coatings for UV resistance and durability.
Metal Roofing for Commercial
Standing seam and structural metal panel systems are increasingly selected for commercial applications due to their exceptional longevity, low maintenance requirements, and compatibility with rooftop solar and mechanical equipment installations. We install structural metal systems engineered for commercial loading and span requirements specific to your building structure.

Frequently Asked Questions
Commercial Roofing Questions
How do you minimize disruption to our business operations during a commercial roofing project? +
We begin every commercial project with a detailed pre-construction planning meeting with your facilities or operations team to understand which areas of the building are most sensitive to noise, dust, or debris, and to establish work hours that accommodate your business schedule. We can stage work to proceed in sections, leaving portions of the roof system intact and watertight at the end of each work day. We use containment systems to prevent debris from entering HVAC intake systems and take all precautions necessary to maintain a safe environment for building occupants and visitors throughout the project.
What commercial roofing warranties does Rivendale Roofing provide? +
Our commercial projects are covered by two types of warranty. First, our written labor warranty covers the quality of our installation work for the period specified in your contract. Second, manufacturer material warranties cover the roofing system components for their rated service life. For major commercial projects, we can qualify for manufacturer-backed system warranties that cover both material and labor, which are only available through certified contractors like Rivendale Roofing. These system warranties are the strongest available coverage for commercial property owners and provide significant value for property asset management purposes.
Can you work with our property management or facilities team on an ongoing maintenance program? +
Yes. We offer structured commercial roof maintenance programs designed around the specific systems installed on your property and the inspection and maintenance requirements of your manufacturer warranty. Regular professional maintenance is required by most commercial roofing manufacturers to keep warranty coverage active, and it is also the most cost-effective approach to extending roof service life and avoiding the large unplanned expenses that result from deferred maintenance. Our maintenance programs include scheduled annual inspections, written condition reports, and priority response for any repair needs identified during or between inspections.
