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.

Ron Otis did an excellent job representing Guardian Roofing. He arrived on time, he did a thorough (and videotaped) inspection of the roof, he provided a clear and pragmatic roofing solution that would best serve the realities of our particular structure, and finally, he gave us a clear and helpful overview of various payment options. Thank you, Ron!

Phase 2 (gutter cleaning, moss abatement, and final finishing of the chimney) is now complete. I can say that Guardian Roofing, Gutters and Insulation continued to meet or exceed my already high expectations. This company receives my tip top recommendation. Guilmar Alarcon, my last technician, continued the professional and efficient performance each person who worked on my project exhibited. A shout out to Joey Harman, who was my direct contact with Guardian. Excellent communication is one of my hallmarks of a great company. Joey kept me in the loop on who would be coming to work, when, and what they would be doing, as well as returning any emails or calls I made promptly and pleasantly. Guardian Roofing is the way to go for all your roofing, gutter, and insulation needs!

Today Gabriel Solano did above and beyond any expectations we had regarding our repairs. He's incredibly knowledgeable, reliable and respectful. Explains the process clear with pictures. Safety first is always the most important, he was tied off always. :) he spoke with my husband over the phone explaining what was taking place while hes not here. Just an overall excellent experience.

I can’t recommend Guardian Roofing, and especially Jose Luis Corona Rios and his crew, highly enough. Communication was clear from start to finish, they showed up when they said they would, and they kept me informed throughout the entire repair process. Their safety protocols were excellent and very professional, and they were consistently respectful of my property while working. They repaired my chimney crown, completed shingle repairs, and fixed flashing, and the work looks great. What I appreciated most was the photos they shared of the work in progress and the completed repairs, since everything was up very high and nearly impossible to see clearly from ground level. The whole experience was smooth and stress-free. I also want to highlight Ryan, the roofing specialist I met with initially for my quote. He had a friendly, low-pressure approach, explained everything clearly, and the photos he provided were incredibly helpful in understanding what was needed. Finally, Deimar, the project engineer, was wonderful to work with. She was attentive, kept us up to date on scheduling, and followed up promptly whenever we had questions. Everyone I interacted with at every step was genuinely friendly and professional. I highly recommend them!

Everyone from Guardian Roofing and Gutters was very helpful after a tree fell on our roof. We needed to replace the garage roof and gutters. Josh worked with our homeowners association and insurance company to help cover the costs. They were efficient and completed the work in a timely manner. It looks great and we have not had any problems. We have used them before and I would not hesitate to use them again.

PNW storm season hits hard... So I called up Guardian Roofing and talked to Deimar, who was fantastic to work with! Of course, this was during the worst PNW torrential rain storm of the century, and my roof started leaking! After talking with them, they had someone come out asap to check it, and then tarp it until they could get to it (because everyone else's roof was leaking too) .. Then they came out to start the job they found some other problems, rotting wood under shingles that were not put on properly ... so I ended up having more work done... BUT, it is done so well, and in a two day time frame, (once they started the job) from rip off, to new wood, to shingles, and proper roof venting (PLUS they fixed my overhang that birds were getting into), to clean up and haul away of all debris!!!! I will not be worrying about this roof leaking or anything for many years to come!!!! Thank you to Deimar for facilitating the job and thanks to the worker, Uriel Rico, who went above and beyond on this job! What a great worker he is, and a pleasant person to deal with. This was for a larger almost flat roof dormer on top of my house. They added in proper venting on the top ridge and at the bottom, or low end too. Job well done!

Guardian Roofing is an amazing company. I had a broken downspout I needed repaired and wanted an exact match to my previous downspout, they immediately answered my call and were so helpful. I spoke with Alicia and she was kind, understanding, well informed and was able to deal with the complexities and difficulties of my job extremely smoothly. They also are extremely good about following up, offer flexible scheduling, and send text messages as well as calls to ensure communication is at its best. I highly recommend this company for your roofing and gutter needs!
