Commercial Metal Roofing Systems and Materials
Our Seattle metal roofing services for commercial properties include the planning, detailing, and installation required to deliver a roof built for long-term performance. Whether for new construction, replacement, or a larger building upgrade, we keep the process clear, organized, and aligned with your property’s needs. Below are the primary metal roofing systems we install.
Standing Seam — A premium commercial metal roofing system with standing seams and concealed fasteners designed to improve weather resistance and long-term durability. It provides a clean, modern appearance while reducing maintenance needs compared to exposed-fastener systems, and is well-suited for properties seeking long service life and a refined finished look.

It offers strong performance and straightforward maintenance, making it a practical solution for many commercial, industrial, and agricultural-style buildings.
Final Cleanup and Jobsite Reset
Ongoing daily cleanup throughout the project and a final walkthrough to ensure the jobsite is clean, safe, and ready for normal operations.
Drainage and Gutter Improvements
Ensuring water moves off the roof properly to prevent ponding and future issues.
Flashing and Edge Metal Upgrades
Replacement or integration of flashing, edge metal, and penetration details to strengthen perimeter protection and support long-term leak prevention on commercial roof replacements.
New Roofing System Installation
Installation of the new commercial roofing system using certified methods and manufacturer-approved details, completed by an experienced commercial roof replacement contractor.
Substrate and Deck Evaluation & Repair
During commercial flat roof replacement, decking, insulation, and structural elements are evaluated and repaired as necessary to support the new roofing system, whether installed as a tear-off or overlay.
Roof Preparation and Selective Removal
When we replace a commercial roof, our approach depends on existing conditions and system design. Projects may involve a full tear-off or selective removal to properly prepare the roof, with clean, controlled debris handling to protect the building and surrounding areas.

Step 1: Schedule Your Free Roof System Evaluation
We visit the property, evaluate the existing conditions or project plans, and document current conditions with photos while identifying what the commercial metal roofing project needs to move forward properly.
Step 2: Approve Your Scope and Project Plan
You receive a clear estimate, recommended scope of work, and timeline so expectations are established before the work begins.

Our crew completes the work, manages cleanup, and keeps you updated throughout the project. At closeout, you receive the documentation needed for warranty support and future roof planning.
Why Commercial Metal Roofing Is a Smart Long-Term Investment
Commercial metal roofing is valued for its durability, lifespan, and clean appearance, but long-term performance depends on more than the material itself. Proper planning, careful detailing, and precise installation are essential, particularly at drainage points, transitions, penetrations, and roof edges.
When properly planned and installed, commercial metal roofing supports better protection against rain and wind, a longer service life with fewer interruptions, stronger performance at seams, edges, and penetrations, and strong long-term value for owners and property managers — meaning fewer surprises and a more dependable roof over time.
Client Testimonials
Our work is measured not just in completed roofs, but in the confidence property managers, owners, and contractors feel throughout the process. These testimonials reflect that commitment.
I hired Ivan for a TPO roofing project, and I couldn’t be happier with the results. He stepped in on very short notice right before the rain was coming, which helped us avoid major issues. His work was professional, clean, and done exactly the way it needed to be.

Commercial Metal Roofing FAQs
What is the best roofing for commercial buildings?
There is no single best roofing system for every commercial property. The right choice depends on the building type, roof slope, exposure, budget, and long-term goals. Commercial metal roofing is often a strong option when durability, lifespan, and weather resistance are top priorities.
What is the biggest problem with metal roofs?
Most issues with metal roofs are related to improper detailing or installation rather than the material itself. Seams, flashing, penetrations, and edge conditions must be handled correctly to ensure long-term performance. When these details are overlooked, leaks and premature problems can occur.
What is the minimum R value for a commercial roof?
The required R value depends on the building type, roof assembly, and current code requirements for the project location. It is not one fixed number for every building. We review insulation needs as part of the planning process so the roofing system supports both performance and code compliance.
What type of metal roofing is best?
The best type depends on the property, the roof design, and the goals of the project. A good commercial metal roofing system should fit the slope, exposure, drainage conditions, and long-term maintenance expectations of the building.
What is better, a 24 or 26 gauge metal roof?
Both 24 gauge and 26 gauge metal panels are used in commercial applications. 24 gauge panels are thicker and may provide increased strength and resistance in more demanding conditions. The appropriate gauge depends on roof design, exposure, and performance goals rather than a one-size-fits-all approach.
How many layers of roofing are allowed on a roof in Washington State?
Washington State building codes generally limit roofs to a maximum of two layers of roofing materials. If a roof already has two layers in place, the existing roofing typically must be removed before installing a new system. Local jurisdiction requirements and existing roof conditions may also affect whether a tear-off is required.
How is a commercial metal roof installed?
Commercial metal roof installation can apply to new construction, full roof replacement, or approved layover (overlay) conditions, depending on the existing roof assembly and project requirements. For new construction, installation typically begins with preparation of the structural roof deck, followed by insulation and vapor control layers when required. In replacement or layover situations, the existing roof is either removed or prepared to create a suitable substrate for the new system.
The metal roofing system is then installed in accordance with manufacturer specifications, with careful attention given to drainage, flashing, penetrations, seams, and roof edges. Each roof assembly is designed to manage water, control heat and moisture, and protect the building from environmental exposure. Installation methods vary based on roof design, slope, structural conditions, and applicable code requirements.
Can a general contractor do roofing in Washington state?
In Washington state, roofing work must be performed by contractors who are properly licensed and insured for roofing services. Some general contractors may hold the appropriate licensing to perform roofing work, but many projects — especially commercial roofing — are completed by specialty roofing contractors due to the technical requirements, manufacturer installation standards, and warranty considerations involved.
What affects the cost of a commercial metal roofing project?
The cost of a commercial metal roofing project depends on several factors. Pricing is influenced by the size and condition of the roof, the type of metal roofing system selected, and the performance requirements of the project.
Common factors that affect cost include:
- Roof size (total square footage) and building configuration
- Type of metal roofing system selected
- Tear-off vs retrofit
- Insulation upgrades and code requirements
- Drainage improvements such as crickets, additional drains, scuppers, or ponding corrections
- Roof complexity, including curbs, skylights, parapets, penetrations, and rooftop equipment
- Site access and staging requirements, such as lifts, cranes, and material loading zones
- Occupancy considerations, including tenant coordination, work hour limitations, and protection of operations
- Warranty level and manufacturer system requirements for qualifying coverage
- Deck repairs if deterioration is discovered during tear-off or preparation
For the most accurate pricing, Washington Weather Shield recommends scheduling a roof inspection to evaluate your specific roof and project needs.
Do you offer written estimates and detailed scopes of work?
Yes. Washington Weather Shield provides written estimates and detailed scopes of work for commercial roofing construction, repairs, maintenance, and roof replacement projects. Our proposals clearly outline the recommended system, project scope, and warranty options so you know exactly what to expect.
How are contracts and payment schedules handled for projects, including new construction roofing?
At Washington Weather Shield, all commercial roofing contracts must be signed prior to the start of the project. Our standard payment schedule is 50% upfront to order materials and secure your installation dates on our calendar, with the remaining 50% due upon completion of the project. For larger commercial roofing projects, progress payments may be requested during the duration of the work, depending on the size and scope.
Are your commercial roofing contractors licensed and certified?
Yes. Washington Weather Shield is fully licensed, and our commercial roofing team is trained and certified to install roofing systems using manufacturer-approved methods for long-term performance and warranty compliance. We are certified with top commercial roofing manufacturers, including GAF (TPO & PVC), Versico (TPO & PVC), Duro-Last (PVC), and GE Enduris—and we’re especially proud to hold GAF GoldElite™ Commercial Contractor status, a highly selective certification level.
What training do your roofing crews receive each year?
At Washington Weather Shield, our commercial roofing crews complete ongoing hands-on training to stay current on the latest installation methods, safety standards, and manufacturer requirements. This includes training and education through top roofing manufacturers such as GAF (TPO & PVC), Versico (TPO & PVC), Duro-Last (PVC), and GE Enduris, helping ensure every roof we install meets professional standards and warranty guidelines.
Do you work with manufacturer-backed roofing systems?
Yes. Washington Weather Shield installs manufacturer-backed commercial roofing systems. All of our roofing systems are built using trusted, manufacturer-approved materials and installation methods to support long-term performance and warranty eligibility.
How do I know I’m hiring a qualified commercial roofer?
A qualified commercial roofer should have proven experience with commercial flat and low-slope roofing, proper licensing and insurance, strong safety practices, and the ability to provide detailed scopes, references, and warranty options. At Washington Weather Shield, we meet these standards through our commercial roofing expertise, manufacturer certifications, and our commitment to professional installation methods and long-term roof performance.
Do you handle commercial new construction roofing as part of larger builds?
Yes. We take on select commercial new construction roofing projects when they align with our scope and scheduling. We work with general contractors, architects, and other trades to coordinate installation with project sequencing and code requirements.
