Can't find your answer? We're here to help.

Services & Pricing

How much does a new roof cost?

The cost of a new roof depends on several factors including size, pitch, materials, and complexity. For a typical Portland-area home, roof replacements generally range from $10,000 to $25,000+. We offer an Instant Price Estimate tool on our website for a close estimate, and all on-site quotes are completely free with no obligation.

How much does an inspection or quote cost?

Nothing. All inspections, consultations, and quotes are provided completely free. We believe in earning your business through education and transparency, not pressure tactics. We'll give you an honest assessment of your roof's condition and explain all your options.

What areas do you service?

We serve the Portland, Oregon metropolitan area, including Portland, Beaverton, Hillsboro, Lake Oswego, Tigard, and Aloha. If you're nearby and not sure if you're in our service area, give us a call!

Do you offer financing options?

Yes! We understand a roof replacement is a significant investment. We offer flexible financing options through our lending partners, with loans typically funded within 1-2 business days. This allows you to get the roof you need now and pay over time with manageable monthly payments.

Qualifications & Trust

Are you licensed, insured, and bonded?

Absolutely. We carry $1,000,000 in liability insurance, are fully licensed with the State of Oregon (CCB # 251336), and are bonded for the required $25,000. We're happy to provide proof of insurance and licensing upon request — any reputable contractor should be.

What sets Evolution RoofWorks apart from other roofers?

We're built on education over sales. Most homeowners only deal with a roof a couple of times in their life, so we walk you through your options in plain language — no industry jargon, no high-pressure tactics, no same-day closing pitch, and no incessant follow-up calls. Beyond that: we're CertainTeed-certified and install CertainTeed shingles exclusively, we bring your attic ventilation up to current code (something most roofers skip), we send daily updates during your project, and we keep the job site clean from start to finish.

How do I know I can trust you?

We understand the roofing industry has trust issues. That's exactly why we operate differently. Check our 5-star Google reviews, ask for references from recent jobs in your neighborhood, verify our CCB license (#251336), and notice that we'll never pressure you into a decision. We believe if we do right by our customers, the business follows.

The Roofing Process

What's included in your free inspection and estimate?

A real, on-the-roof inspection — not a drone flyover. We get on the roof to check the shingles, granule loss, broken seals, and all the flashings, and we always go into the attic too, since leaks, mold, and ventilation problems usually show up there first. For replacements, we draw up a written proposal the same day and sit down to walk you through it — including four different pricing options so you can choose what fits your home and budget. We'd rather you understand exactly what you're buying than feel rushed into a decision.

How long will it take to replace my roof?

A typical average-sized residential roof is completed in 2 to 3 business days. More complex roofs with multiple levels, steep pitches, or extensive flashing work may take longer. We'll give you a clear timeline upfront and keep you informed throughout the process.

What kind of weather can you work in?

We can work around almost any weather conditions common to the Pacific Northwest — and trust us, we're used to it! Rain doesn't stop us from completing most projects safely. However, for your roof's best performance, we time certain critical installations (like underlayment) during appropriate conditions.

Do I need to be home during the roof inspection?

Not necessarily. As long as you give us permission to access your roof, you don't need to be present. However, many homeowners prefer to be there so they can ask questions and see any issues firsthand. We're happy to work around your schedule either way.

Do I need to be home during the roof replacement?

You don't need to be home for the entire project, but we recommend being available (or reachable by phone) at the start of the job and for the final walkthrough. We'll protect your landscaping, clean up thoroughly, and leave your property better than we found it.

What should I expect on installation day?

Our crew typically arrives between 7-8 AM. We'll protect your landscaping with tarps, set up materials efficiently, and work systematically across your roof. Expect some noise — roofing isn't quiet work! We clean up daily and do a thorough magnetic sweep for nails. At project completion, we'll walk you through everything we did.

Warranty & Maintenance

What kind of warranty do you offer?

Two layers of coverage. First, a 10-year transferable workmanship warranty on our installation. Second — and this is the big one — because we're CertainTeed-certified, we can offer their extended warranty that is fully non-prorated for 50 years. That matters because a standard shingle 'lifetime warranty' is largely a marketing term: it's typically only non-prorated for about 10 years, then loses value, and it usually only covers the replacement shingles themselves — not the labor to tear off and dispose of defective shingles, or the flashing and accessory components. With a standard warranty, you could be on the hook for roughly 60% of the cost even in year one. The CertainTeed extended warranty covers all of it. CertainTeed is also the only manufacturer that warranties cosmetic issues like color mismatch and uneven fading.

What does 'transferable warranty' mean?

A transferable warranty means if you sell your home within the warranty period, the coverage transfers to the new owner. This adds value to your home and gives buyers confidence in the roof's quality. We provide documentation to make the transfer process simple.

Do you recommend preventative maintenance?

Absolutely! Proper maintenance is the single best way to extend the life of your roof. We recommend annual inspections, regular gutter cleaning, and moss treatments (especially important in the Pacific Northwest). These simple steps can add 5-10 years to your roof's lifespan. We offer professional maintenance programs to make this easy.

How often should I have my roof inspected?

We recommend a professional inspection at least once a year, ideally in late fall before the rainy season hits. You should also have your roof inspected after any major storm with high winds or hail. Catching small issues early prevents expensive repairs later.

Pacific Northwest Roofing

What roofing materials work best in Portland's climate?

We specialize in residential asphalt shingle roofing and install CertainTeed shingles exclusively. CertainTeed has a long-standing reputation as one of the highest-quality shingle manufacturers, and they're the only manufacturer that warranties cosmetic issues like color mismatch and fading. Their architectural shingles offer excellent moss and algae resistance and strong wind ratings — well suited to the wet Pacific Northwest climate.

How do you handle moss and algae issues?

Moss and algae are common in our wet climate and can significantly shorten your roof's lifespan if left untreated. We offer moss treatment services, and all the shingles we install include algae-resistant technology. For existing roofs, we can apply zinc strips and treatments to prevent future growth.

Is ventilation really that important in Oregon?

It's one of the most overlooked parts of a roof — and one we take seriously. Oregon's attic ventilation code actually doubled in the last decade (from 1 square foot of ventilation per 300 square feet of attic to 1 per 150), and the vast majority of homes we inspect don't meet today's standard. Proper ventilation keeps heat and moisture out of your attic, which prevents mold (a real health concern in our wet climate), lowers both your heating and cooling bills, and extends the life of your shingles by an estimated 7–15%. Many roofers treat ventilation as 'not their problem' because it isn't technically part of the roof. We bring every roof we install up to current ventilation code.

What about ice dams in winter?

While Portland doesn't get as much snow as other regions, ice dams can still occur during cold snaps. Proper attic insulation and ventilation are your best defenses. When we install a roof, we ensure your ventilation is set up correctly to minimize ice dam risk. For existing problem areas, we can install ice and water shield barrier protection.

Repairs

Can you repair just part of my roof?

Often, yes. If damage is localized and the rest of your roof is in good condition, targeted repairs make sense. However, we'll always give you an honest assessment. If repairs would be a bandaid on a roof that needs replacement, we'll tell you that too — and explain why. We'd rather earn your trust than make a quick buck.
