If you manage a commercial building in the Puget Sound region, you already know how important your roofing system is to the overall health of your property. From protecting tenants and equipment to keeping energy costs down, the right roofing solution makes a big difference. But with so many options available, how do you choose the best commercial roofing contractors in Seattle?
At Orca Roofing & Exteriors, we specialize in commercial roofing for businesses, multifamily buildings, and HOAs throughout Seattle. In this guide, we’ll break down your roofing options, share tips for choosing a contractor, and explain how regular maintenance can help extend the lifespan of your roof.
Why Commercial Roofing Requires Specialized Expertise
Unlike residential roofing, commercial roofing in Seattle demands unique considerations:
- Larger square footage
- Flat or low-slope structures
- HVAC systems or other rooftop equipment
- Compliance with local codes and energy regulations
You’ll want a contractor that not only understands these challenges but also offers long-term solutions—especially in Seattle’s rainy, wind-prone climate.

Popular Types of Commercial Roofing in Seattle
Whether you’re maintaining a warehouse, retail space, apartment complex, or HOA-managed property, the right roofing system depends on your building type and budget. Common options include:
TPO and PVC Membranes
Durable, energy-efficient, and ideal for flat roofs. These systems resist UV rays, chemicals, and water infiltration.
Torch Down Roofing
A common solution for low-slope roofs, torch down systems offer excellent waterproofing and weather resistance.
Metal Roofing
Sleek, long-lasting, and sustainable, metal roofing is often used for commercial buildings that want minimal maintenance.
Composite and Synthetic Tiles
For HOAs or multifamily buildings seeking aesthetic appeal, synthetic roofing materials like Brava offer high-end looks with lower maintenance.

FAQ – Commercial Roofing Seattle

What is commercial roofing?
Commercial roofing refers to the materials and installation methods used to protect non-residential buildings like offices, warehouses, retail spaces, and apartment complexes. Unlike residential roofs, which are typically pitched and use shingles, commercial roofing systems often feature flat or low-slope designs and use materials like TPO, PVC, metal, or torch down membranes. At Orca Roofing & Exteriors, we specialize in tailored solutions for commercial properties across the Seattle area.
Why do commercial buildings have flat roofs?
Flat roofs are common on commercial buildings for several practical reasons. They’re more cost-effective to construct over large areas, easier to access for maintenance, and allow for equipment like HVAC systems to be installed directly on the roof. Flat roofing systems also make it easier to install solar panels or green roofing features. Our team at Orca Roofing designs commercial roofing systems in Seattle that take full advantage of these benefits while ensuring long-term performance and durability.
How to choose a good commercial roofing contractor?
When searching for commercial roofing contractors in Seattle, look for companies with proven experience in flat and low-slope systems, proper licensing, and strong local reviews. A quality contractor will:
- Be licensed, bonded, and insured
- Offer detailed, transparent estimates
- Have experience with commercial-grade materials
- Provide preventative maintenance plans
- Use in-house crews (not just subcontractors)
Orca Roofing & Exteriors checks all these boxes and is trusted by property managers and HOAs throughout the Puget Sound region.
How to fix a commercial roof leak?

- Conduct a detailed inspection
- Remove damaged material
- Seal or replace affected membrane sections
- Check for additional vulnerabilities nearby
