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.

FAQs on Commercial Roof Replacement
What is the most common commercial roofing system?
The most common type of commercial roofing is a single-ply membrane system installed on flat or low-slope roofs—typically TPO (Thermoplastic Polyolefin). TPO is popular because it’s durable, energy-efficient, and performs well in many commercial applications.
How can I estimate the cost of replacing a roof?
To estimate the cost of replacing a roof, start with the roof size (square footage) and the type of roofing system needed, then factor in the roof’s condition, complexity, and any insulation or code upgrades.
How long is a typical commercial roof warranty?
A typical commercial roof warranty depends on the roofing system and manufacturer, but most warranties range from 10 to 30 years or longer. Coverage can vary widely by warranty tier.
Higher-tier warranties may include full coverage for materials, labor, tear-off, and workmanship for a set period of time, while standard or limited warranties often cover materials only and may be prorated or shorter in duration. The exact warranty terms depend on the roofing system selected and how it is installed.
What is the most expensive part of replacing a roof?
The most expensive part of a commercial roof replacement is usually labor and tear-off, especially when removing multiple roof layers, hauling debris, and safely preparing the roof for a new system. Costs can also increase when projects require insulation upgrades, tapered drainage, complex flashing details, or repairs to damaged decking discovered during tear-off.
Other major cost drivers include:
- Roof access and safety requirements (lifts, cranes, staging)
- High detail areas (parapets, curbs, skylights, HVAC penetrations)
- Warranty level and manufacturer requirements (ex: GAF, Versico, Duro-Last, GE Enduris)
How long will a commercial roof last?
Most commercial roofs last 15–30+ years, depending on the roofing system, installation quality, weather exposure, and ongoing maintenance. At Washington Weather Shield, we design and install commercial roofing systems built for long-term performance in Western Washington conditions.
Roof lifespan depends on factors like:
- Roofing material (TPO, PVC, EPDM, metal, coatings)
- Drainage and ponding water prevention
- Foot traffic and rooftop equipment
- Quality of flashing and roof details
- Routine inspections and repairs
Which roof is better, EPDM or TPO?
It depends on your building and goals—TPO (Thermoplastic Polyolefin) and EPDM (Ethylene Propylene Diene Monomer) are both proven commercial roofing systems, but they perform differently.
TPO is often preferred for many commercial buildings because it’s heat-reflective, energy-efficient, and highly resistant to UV exposure, making it a strong choice for flat and low-slope roofs.
EPDM is a cost-effective rubber membrane that can be very reliable and is often easier to repair, but it typically doesn’t offer the same reflective “cool roof” benefits as TPO.
What affects the price of a commercial roof replacement?
The price of a commercial roof replacement depends on your building’s size, roof type, and how much work is needed to create a long-lasting, watertight system. At Washington Weather Shield, we build pricing based on the real conditions of your roof.
Common factors that affect cost include:
- Roof size (square footage) and number of levels
- Roof system selected (TPO, PVC, EPDM, metal, or coatings)
- Tear-off vs. re-cover (installing over an existing roof when allowed)
- Insulation needs (code upgrades, tapered insulation, energy efficiency)
- Roof complexity (drains, skylights, curbs, parapet walls, penetrations)
- Access and staging requirements (cranes, lifts, parking, loading zones)
- Safety and occupancy needs (tenant protection, work hours, noise limits)
- Warranty type and coverage level (manufacturer warranties vs workmanship)
Repairs to decking or structural components if damage is found
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 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 do contracts and payment schedules work for commercial roofing projects?
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 each year 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.
