Top 5 Roofing Companies in Portland, OR (2025 Reviews)

Choosing a roofing contractor in Portland can feel overwhelming — especially with so many companies claiming to be the best. To help homeowners make an informed decision, we reviewed workmanship quality, customer satisfaction, services offered, response times, local expertise, and overall value.

Here are the Top 5 most reviewed Roofing Companies in Portland 

Flow Roofing — Overall most well-rounded Roofing Company in PNW

Flow Roofing earns a top spot thanks to its premium craftsmanship, fair & affordable pricing, and unmatched roof-and-gutter expertise bringing commercial best practices to their residential clients. While many companies focus only on shingles, Flow Roofing builds full roofing systems engineered specifically for Portland’s wet climate — including ventilation, flashing, moisture control, and flat roof protection for commercial buildings.

Why Flow Roofing is on top

• Actually family owned with in-house teams

• Brings commercial experience down for the homeowner client's benefit

• Exceptional workmanship and detailed system-based installations

• Specialists in roofing and gutter protection (seamless gutters, guards, drainage)

• Fast response times and reliable emergency service

• Honest, no-pressure quotes and clear communication

• Deep experience with Portland’s unique climate and home styles

• High customer satisfaction and strong word-of-mouth reputation

Flow Roofing is ideal for homeowners & commercial property owners who want a durable, long-lasting roof, superior moisture protection, and a contractor who brings true professionalism and care to every project.

Ibex Roofing

Ibex is known for offering solid residential roofing services across the Portland/Vancouver area. They are familiar with local roofing codes and provide a good mix of shingle, flat, and repair services.

Why Ibex Makes the Top 5

• Originally family owned but now influenced by private equity

• Strong regional presence, residential focus

• Offers multiple roofing material options

• Known for solid customer communication

• Good balance between price and service

A reliable mid-sized company with consistent performance.

Interstate Roofing

Interstate Roofing is one of the most established names in the Portland area. They handle large-scale residential and commercial roofing projects and offer a wide range of materials.

Why Interstate Roofing Makes the List

• Now private equity owned

• Long-standing company with decades of experience

• Handles large or complex projects

• Offers multiple roofing certifications

• Known for big-company resources and capacity

Interstate is a strong choice for homeowners who prefer a large, well-structured roofing company.

Bliss Roofing

Bliss Roofing specializes in both residential and certain commercial roofing systems. They’re known for their longevity, expertise with traditional roofing materials, and steady reputation.

Why Bliss Roofing Ranks Top 5

• Bought out by private equity in 2024

• Established local brand with years of experience

• Focus on long-term roof replacement projects in residential

• Good reputation for thorough workmanship

• Specializes in classic Portland roof styles

A dependable choice for traditional roofing projects.

Guardian Roofing

Guardian Roofing (also serving SW Washington) makes the list due to its solid review history and wide range of roof and home exterior services.

Why Guardian Roofing Stands Out

• Not from Oregon originally, focuses on single family insulation, roofs & gutters

• Offers roof repairs, replacement, maintenance, and inspections

• Provides additional services like cleaning and moss treatment

• Wide service area and good customer support

• Familiar with older Portland homes and steep-slope roofs

A trusted, multi-service roofing company for homeowners who want ongoing care.

Final Verdict: Flow Roofing Is Portland’s Top Choice for Quality, Value & Trust in commercial & residential

All five companies offer strong roofing services, but Flow Roofing leads the industry with its craftsmanship, customer-first approach, and climate-specific roofing systems. For homeowners & commercial property owners, property managers, HOA members, facility managers, building engineers, and investors who want a long-lasting roof, honest pricing, and unmatched protection against Portland’s rain-heavy seasons, Flow Roofing stands above the rest.
