Proven Commercial Roofing Contractor in the Pacific Northwest

A strong commercial roof protects more than just a building—it safeguards operations, tenants, and long-term investments. Guardian Roofing, Gutters & Insulation delivers proven roofing solutions across the Pacific Northwest, combining durable materials with decades of technical experience.

We partner with property managers, business owners, and facilities teams to install, maintain, and repair roofing systems that meet structural needs and exceed code requirements. Our approach is tailored for retail centers, offices, warehouses, and other commercial structures that demand precision, planning, and reliable performance over time.

Commercial Properties We Service

Guardian supports a wide range of commercial clients with roofing solutions that match the scale, structure, and operational demands of each property. Our experience covers buildings across the public and private sectors, all with unique occupancy patterns and roofing needs.

  • Retail Centers and Strip Malls: High-traffic buildings with visible exteriors benefit from weather-resistant, low-maintenance roofing that protects merchandise and storefronts.
  • Office Buildings and Campuses: Professional environments need quiet, clean installations with minimal disruption to daily operations or parking access.
  • Warehouses and Light Industrial Facilities: These structures often demand durable flat roofing systems, energy-efficiency upgrades, and reinforced drainage for wide roof spans.
  • Multi-Use and Mixed-Occupancy Properties: From live-work buildings to commercial plazas, we help owners manage complex roof layouts under one contract with centralized communication.

Each site is evaluated for traffic exposure, drainage patterns, insulation needs, and long-term value. Our team designs systems that meet building codes, climate demands, and your capital improvement plan.

Commercial Roofing Services We Provide

Guardian offers a full range of roofing services designed to extend performance, reduce liability, and meet operational demands across commercial buildings.

  • New Roof Installation and Replacement: We install flat and low-slope roofing systems with high-performing materials like single-ply membranes, modified bitumen, and reinforced asphalt. Our team handles tear-off, disposal, substrate repair, and full system installation with project timelines designed to minimize disruption.
  • Leak Detection and Targeted Repair: Commercial roofs can develop leaks around HVAC units, parapet walls, skylights, and transitions. Our inspection team locates the source of intrusion and performs durable, code-compliant repairs without unnecessary upsells.
  • Preventive Maintenance and Service Programs: Scheduled maintenance extends the life of your roof and helps avoid costly emergency repairs. We clear debris, check drainage, inspect flashing, and document roof conditions so building managers stay ahead of issues.
  • Emergency Response and Storm Damage Repair: When wind, rain, or falling branches compromise your roof, Guardian responds quickly with tarping, repair, and restoration services to secure the structure and keep businesses open.

Every service is documented with before-and-after photos, detailed reports, and invoicing tailored to meet internal review and compliance requirements.

Structured Project Management for Commercial Clients

Commercial roofing jobs demand more than strong installation—they require coordination, compliance, and professionalism throughout every phase. Guardian Roofing, Gutters & Insulation brings a structured project management approach to ensure timelines are met and stakeholders stay informed. Before work begins, we conduct a thorough site assessment, review access logistics, and confirm any permitting requirements. Our team establishes a single point of contact, shares a detailed work schedule, and provides safety documentation for internal teams or tenant notices.

During installation or repair, crews arrive in branded vehicles, follow posted site protocols, and respect business hours to minimize interruption. We maintain a clean worksite, protect surrounding structures, and keep management updated with regular progress photos and reporting. When the work is done, we walk the site, verify all punch list items, and provide a final report ready for audit or archive.

Where Precision Roofing Meets Operational Demands

A reliable roofing partner makes property management simpler. Guardian’s commercial services are built for longevity, code compliance, and minimal disruption—ideal for owners and managers balancing multiple priorities.

As a GAF Master Elite and Owens Corning Platinum Preferred Contractor, we bring nationally recognized standards to every commercial roof we inspect, repair, or replace. That’s the level of care your buildings—and tenants—deserve.

Our Valued Clients

We are very pleased with the work Jose and Victor did installing our four new skylights. This was a replacement of 25+ year skylights. They got the job done just before the rain started.

Andrew was familiar to me from my roofing experience in MAR 2020. He is a very friendly person and always gives me good advice. He fixed a small roof problem on the spot. I have done several large projects with Guardian and have always been very satisfied. And Andrew has been the main person on these projects that I can communicate with. Uriel was the tech who did the work. He is amazingly fast and efficient and the work looks very good. Cleanup was 100%

Josh, on behalf of Guardian Roofing, inspected my roof & discovered the source of a leak that I was experiencing. Three other companies had been unable to find it. Josh took pictures of the leak location to verify what he found. In addition, there were some issues with the installation of the roof vents which he recommended resolving while they were repairing the leak. I was very impressed with how thorough the inspection was and obviously very happy they found the source of the leak. Josh explained the repair process in a way that was easy to understand. I am very satisfied with the experience I had.

Awesome experience with Guardian Roofing, I unfortunately experienced some bad workmanship from a different company and wasn’t comfortable giving them any more of money to fix their mistakes. So I reached out to guardian with a very tight timeline to get the repairs done and they did a fabulous job. I will be sure to contact them again on my next roofing project.

Maison Becker. dude was legit. Explained everything I needed/wanted to know about the conditions of my roof and had no issues with any notices of the entire process and I was offered excellent choices of what to replace my shingles, plywood itself & gutters to reensure the safety and quality of the products ! Gotta hand it to the guy, with all the background knowledge I was given of the company and specialists, I am not surprised at all these guys are number 1 around the area with improvements to be involved with every step, I've learned they are willingly trying to exchange ethics for trust. I was also quickly breezed by the payment options with satisfaction especially here in Tacoma through this dramatic cost of living season. I highly recommend anyone who has problems with their roofing/gutters to give these guys a shot to check you out & get some knowledge behind it all. Thank you for the visit. Can't wait to get started.

Second time seeing Joe. Bought a new house and it was a pleasure to see Joe again. He's very professional and gets to the point. I like how he uses video to show you what's up with your roof. Gives me a sense of security knowing exactly what is happening.

Excellent job repairing my roof. Other roofers had said that we needed a full replacement. Guardian is honest and stated that my current roof still has 10-15 years of durability still remaining.
