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.

Called Guardian with urgent roofing repair after a storm. They called early next morning, and had someone out later that morning for bid and tarp the hole. Dallas was very professional, efficient, took video of the repairs needed with detailed explanation while he was walking on our roof. The deposit for urgent tarping included in bid. The bid was very reasonable. All over good experience. They are able to come repair the roof in a few days.

Guardian was very responsive, setting our appointment for the day after we called (serious leaks in garage roof). Josh came out and did an extensive and professional job of checking for the leak points. He examined all of the attic space even though it seemed the leaks were in a limited area. Found at least one spot I hadn't found. He then went on the roof (in the heavy wind) and took pictures of the areas of the leaks, identifying the problems we needed to address. He presented us with his findings (with video), walking us through the issues. He worked up our contract and we are awaiting scheduling to get the work done. All in all a great experience. We are sure the work will be high quality also. Would definitely recommend Josh and Guardian.

Roofing is 7 years old and there is leaking behind the gutters all the way around. Been happening for years. Drew determined that there should have been a metal flange installed under the edge of the roof that angles down over the inside edge of gutter.

Justin came out twice and finally found a mysterious roof leak that did not stain the wall. He was thorough, considerate and patiently walked me through the entire process.

They came and did a thorough evaluation. They did the work they said they would do. My only complaint is that there were too many contacts. I would prefer one responsible person from start to finish. However, they did get the job done, on schedule: competent and courteous. New roof (down to wood: new underlayers, vents, etc.) and new attic insulation.
