5 Questions to Ask Commercial Roofing Contractors Before Hiring

• Are You Licensed, Insured, and Bonded?

Why This Matters

Not all roofing contractors are properly licensed or insured. Without these protections, you could be on the hook for damages or injuries during the project.

What to Look For

• A valid contractor’s license in Oregon.
• General liability insurance to cover property damage.
• Worker’s compensation insurance to protect workers.
• A surety bond to ensure the contractor completes the job as promised.

Follow-Up Question

Can you provide documentation for your license, insurance, and bond? A reliable contractor will be happy to share proof. If they hesitate or dodge the question, that’s a major red flag.

• What Experience Do You Have with Commercial Roofing in Portland?

Commercial roofing is different from residential roofing. It requires specialized knowledge, other materials, and an understanding of how Portland’s climate affects roofing systems.

What to Look For

• Experience with commercial buildings, not just houses.
• Knowledge of flat and low-slope roofing systems like TPO, EPDM, and metal.
• Familiarity with local building codes and permitting processes.

Follow-Up Question

Can you show examples of similar commercial roofing projects you’ve completed? Seeing past work or speaking with previous clients gives you a better idea of their experience level.

If you’re searching for reliable commercial roofing contractors in Portland, look for companies that have worked on buildings like yours before. The last thing you want is a contractor who’s never installed the type of roof your business needs.

• What Roofing Materials and Systems Do You Recommend?

Choosing the roofing material affects durability, energy efficiency, and maintenance costs. Portland’s weather means you need something that can handle rain, wind, and temperature changes.

What to Look For

• Recommendations tailored to your building type and climate.
• Roofing materials have a good balance of cost, lifespan, and maintenance needs.
• Systems that offer energy efficiency, such as cool roofs that reflect sunlight.

Follow-Up Question

What are the pros and cons of different materials? A knowledgeable contractor will break down the benefits and drawbacks of options like:

• TPO Roofing – Lightweight, energy-efficient, and durable.
• EPDM Roofing – Cost-effective and long-lasting.
• Metal Roofing – Highly durable and weather-resistant.
• Built-Up Roofing (BUR) – Provides multiple layers of protection.

The right contractor won’t push the most expensive option. Instead, they’ll help you find the best fit for your business.

• What’s Included in the Estimate?

A vague estimate can lead to unexpected costs and disputes. A detailed breakdown helps you understand exactly what you’re paying for.

What to Look For

• A clear list of materials, labor, permits, and cleanup costs.
• Any potential additional fees for unforeseen repairs.
• A payment schedule so you know what’s due and when.

Follow-Up Question

Are there any hidden costs or additional charges that might come up? Some contractors offer a low initial quote but add surprise costs later. A trustworthy company will be upfront about all potential expenses.

If you compare commercial roofing contractors in Portland, ensure their estimates include everything—so you don’t get hit with unexpected bills.

• What Kind of Warranty Do You Offer?

A roof is a significant investment. A solid warranty protects you if something goes wrong after installation.

What to Look For

• A manufacturer’s warranty on materials (typically 10-30 years).
• A workmanship warranty that covers installation errors (often 5-10 years).
• Clear terms on what voids the warranty, such as lack of maintenance.

What happens if I have a problem after installation? A reliable contractor will have a transparent process for handling warranty claims and repairs.

• How Will You Handle Weather-Related Delays?

Portland’s weather is unpredictable. Rain, wind, and even unexpected temperature drops can affect roofing schedules. You need a contractor who has a solid plan for dealing with delays.

What to Look For

• A contractor who monitors weather conditions and adjusts the schedule accordingly.
• A clear communication plan so you’re not left wondering what’s happening.
• Steps were taken to protect materials and work-in-progress during bad weather.

Follow-Up Question

What’s your policy for rescheduling due to weather delays? A professional contractor will be upfront about handling unexpected weather and how it affects your timeline.
