Commercial roofing demands a different level of planning, coordination, and technical expertise than residential work. The stakes are higher, a failed commercial roof can disrupt operations, damage inventory, and create liability. Integrity Roofing & Construction brings the same commitment to quality that drives our residential work to every commercial project, backed by the licensing, insurance, and experience that commercial property owners require.
We serve commercial property owners, property managers, and business owners throughout Greater Seattle, providing installation, replacement, repair, and maintenance services for flat and low-slope commercial roofing systems.

Commercial Roofing Services We Provide
TPO (Thermoplastic Polyolefin) Roofing
TPO is one of the most widely used commercial roofing membranes in the industry. It offers excellent resistance to UV exposure, punctures, and chemical exposure, and its white reflective surface contributes to energy efficiency. TPO is a strong choice for Greater Seattle commercial properties looking for a cost-effective, durable flat roofing solution.
EPDM (Ethylene Propylene Diene Monomer) Roofing
EPDM is a synthetic rubber membrane known for its exceptional durability and resistance to ozone, UV radiation, and temperature extremes. It’s particularly well-suited to the Pacific Northwest’s wet climate and has a proven track record of performance in commercial applications over multiple decades.
Modified Bitumen Roofing
Modified bitumen is an asphalt-based system reinforced with fiberglass or polyester matting, providing excellent waterproofing performance and durability. It’s a strong option for commercial properties that require a proven, redundant waterproofing layer.
Commercial Roof Repair and Maintenance
We provide repair services for commercial roofing systems of all types, addressing leaks, membrane damage, flashing failures, and drainage issues. Regular preventive maintenance contracts help commercial property owners in Greater Seattle extend the life of their roofing system and reduce emergency repair costs.
Common Commercial Roofing Problems in Greater Seattle
Ponding Water
Flat and low-slope roofs are susceptible to ponding water — standing water that remains on the roof surface for 48 hours or more after rainfall. Ponding water accelerates membrane degradation, increases structural load, and is one of the leading causes of commercial roof failure.
Membrane Punctures and Tears
Commercial roofing membranes can be punctured by foot traffic, falling debris, or HVAC equipment installation and servicing. Punctures create direct paths for water infiltration and require prompt repair.
Flashing Failures at Penetrations and Edges
Commercial roofs have numerous penetrations — HVAC units, vents, drains, pipes, and equipment curbs — all of which require properly sealed flashing. Edge and parapet flashing is also a common failure point.
Improper Drainage
Roof drains, scuppers, and gutters on commercial properties require regular clearing to function correctly. Blocked drainage leads to ponding, which leads to accelerated membrane wear and eventually leaks.
Frequently Asked Questions About Commercial Roofing in Greater Seattle
Can commercial roofing work be scheduled to minimize business disruption?
Yes. We work with commercial property owners and managers to schedule work during hours that minimize impact on business operations. For larger projects, phased scheduling can allow sections of the building to remain operational throughout the project.
How long do commercial flat roofs last?
Lifespan depends on the membrane type and maintenance. TPO and EPDM systems typically last 20 to 30 years with proper maintenance. Modified bitumen systems are similar. Regular inspections and preventive maintenance are the most effective ways to maximize commercial roof lifespan.
Does Integrity Roofing offer commercial roofing maintenance contracts?
Yes. We offer ongoing maintenance agreements for commercial properties that include regular inspections, drainage clearing, minor repairs, and detailed condition reports.
Is Integrity Roofing licensed for commercial work in Washington State?
Yes. We hold Washington State General Contractor Registration #INTEGRC841J1 and carry appropriate licensing and insurance for both residential and commercial roofing projects throughout Greater Seattle.
What should I do if my commercial roof is actively leaking?
Contact us immediately. Active leaks require prompt response to prevent water from spreading through the building envelope and causing secondary damage to interiors, insulation, and structural components.
