Our Residential Roofing Services in Lake Oswego
We cover the full range of residential roofing Lake Oswego homeowners search for: roof installation, repair, and maintenance, plus gutters, free inspections, and storm-damage support. Every inspection and estimate is free, and our roofing contractors recommend based on what the roof needs, not what sells the biggest job. When a leak or storm damage can’t wait, emergency service is available around the clock, and in many cases we can get a crew out the same day. You can read more on our main roofing services page, or start below.
Roof Repair
Roof repair fixes isolated problems before they become whole-roof problems. We handle active leaks, damaged or missing shingles, failed flashing around chimneys and skylights, and sealing at vulnerable penetrations where water finds its way in.
Most smaller repairs are completed in a few hours once we know the source, and urgent leaks can often be addressed the same day we inspect. The harder part is diagnosis, and that is where the inspection earns its keep. A stain on a ceiling rarely sits directly below the leak, especially on the valleys and additions common to older Lake Oswego homes. We trace water to its origin, repair the roofing system around it, and confirm the surrounding roof is still serviceable. Catching moisture early also helps prevent mold from taking hold inside the home. When the damage is contained, a focused roof repair protects your home without the cost of a full replacement.
Roof Replacement and New Roof Installation
Roof replacement means a complete roofing system, not a surface refresh. We tear off the old roofing, inspect and address the decking, then build back up with underlayment, proper flashing, ventilation, and new roofing materials. A full replacement includes tear off, so the new roof sits on a sound foundation rather than hiding old problems. Whether it is your first roof on a newer property or a whole new roof on a home you have owned for decades, the process is the same.
Our roof installation work covers asphalt shingle roofs, tile, metal, and flat roofs or single-ply systems, and we help you choose the one that fits your home’s architecture and slope. We install quality products including Owens Corning roofing systems for homeowners who want a trusted shingle line. Most residential roof replacements and roof installation projects run one to three days once scheduled, though size, pitch, access, and decking repairs move that window. We also handle commercial roofing when a property owner has larger needs. Our standard does not change: done once, done right, so you are not chasing callbacks a season later.
Metal Roof Installation and Full Replacement Options
A metal roof holds up well against the wet winters here and sheds moisture and debris efficiently on steeper pitches, while architectural asphalt shingles remain the most common choice for a new roof on most homes. If your project calls for a full replacement, we walk you through each material option so the choice fits your home, your budget, and your long-term plans. Where a roof’s geometry or structure must change, we explain any structural changes clearly before the work is approved.
Roof Inspection, Maintenance and Roof Cleaning
Inspection and roof maintenance catch small issues before they turn into expensive ones. We check the roof surface, flashing, penetrations, drainage, and ventilation, then tell you plainly what we found and what, if anything, needs attention.
This matters in Lake Oswego because the terrain includes steep wooded slopes, gullies, ravines, and the lake and river corridors that shaped how homes were built here. Shaded, tree-covered roof sections hold moisture and grow moss, and thorough moss management and roof cleaning are among the most important routines for a roof through the wet winters. We clear debris before it blocks drainage, manage moss without aggressive methods that shorten shingle life, confirm valleys and downspouts are flowing, and set a monitoring schedule so a serviceable roof stays that way. Regular roof cleaning also protects the shingle surface and keeps your roofing system performing the way it was built to.
Gutters, Storm Damage and Insurance Support
We install and repair gutters, handle gutter replacement, document storm damage, and help you communicate with your insurance provider. Gutters and downspouts carry water off and away from the home, and when the gutters fail, the roof and foundation pay for it, so we treat gutters as part of the roofing system rather than an afterthought. Keeping gutters clear is a small part of roof maintenance that prevents much larger problems.
After a storm, fast action limits the damage, and emergency service is available 24/7 for temporary protection before permanent work is scheduled. If you plan to file a claim, we photograph and document the visible conditions and walk you through the process. We do not promise approval, coverage, or a particular settlement. We give you a clear record and honest guidance so you can make your own decision.

Why Lake Oswego Homeowners Choose the Best Roofing Company for the Job
Homeowners choose us because we back our claims with structure, credentials, and proof rather than adjectives. We are a locally owned roofing contractor that runs in-house crews instead of subcontracting your roof to whoever is available, and we carry Oregon CCB #259776 through the Oregon Construction Contractors Board. BuildZoom places Cobex in the top 1% of California licensed contractors, a ranking we mention with its source attached because that is how trust should work. Customer satisfaction is the measure we care about most, and our customers tell us we do an excellent job.
The honest worry behind looking for roofing contractors near you is that a contractor will say anything to land the job. We understand that, and most homeowners have either lived it or heard the stories. So here is how we answer it with facts.
Lake Oswego permit applications require the listed contractor to provide an Oregon CCB number and to hold either a City of Lake Oswego or qualifying Metro business license. Those are baseline requirements, and we meet them. When you compare roofing companies, look closely at licensing history and customer references, and ask any company to show proof of insurance and warranty details in writing. A reputable roofer carries general liability and workers’ compensation coverage and provides that documentation on request. In our industry a ten-year workmanship warranty is a common standard, and manufacturer certifications can extend coverage on the roofing materials themselves, tied to the product system installed.
With a median owner-occupied home value of $932,200 in Lake Oswego, your roof protects a significant investment. We treat it that way, and it is why so many homeowners here call us when they want the best roofing company for the job rather than the cheapest bid.

Excellent Communication, No Surprises
You will not be chasing us for updates, because someone is assigned to keep you informed. Every roofing project runs through a dedicated project manager, supported by a Client Success Manager whose job is communication, not sales. Excellent communication is built into how we run each specific project, not left to chance.
Before work begins, we confirm your schedule and material delivery. As the job moves, we send progress updates and let you know when weather affects the plan. When it is finished, we do a final walkthrough with you, so you see the completed work and the cleaned-up site before we leave rather than finding surprises later. Your written estimate spells out the roofing materials going on your roof and who is responsible for cleanup, so nothing is left to assumption. This is our concierge model, and it exists because family is how we operate, not a slogan we print.
Fair Pricing and Financing
We do not publish a citywide roofing price because an honest number depends on your specific roof. Size, pitch, access, material, the number of tear-off layers, flashing, ventilation, and decking condition all move the quote, and no two Lake Oswego roofs are identical. Anyone advertising a flat price is guessing, and often the guess is wrong.
Instead, we inspect your roof and give you a detailed written estimate that outlines the full scope of work and the total cost. We encourage you to request multiple written estimates from different roofing contractors before you hire anyone, and to compare what each one actually includes, because a low bid that leaves out flashing, ventilation, or decking is not really lower. A clear original estimate protects you from change-order surprises down the line.
On payment: financing is available to help manage the cost of a roof replacement, and many roofing companies in the area offer similar options. A deposit is commonly required before work begins, and paying by credit card can carry a processing fee, so ask how any contractor handles that. We are not the cheapest, and we say so plainly. We install quality roofing materials at a fair price because fair pricing protects your investment, not because it pads a bill.

How Our Roofing Services Work, From First Call to Final Walkthrough
Our process is built so you always know what is next, from the first conversation through the entire process to the day we clean up and leave.
- 1. Free inspection. We come to your home, inspect the roof, attic, flashing, drainage, and ventilation, and tell you what we found. The inspection and estimate are free, with no obligation to proceed, and for urgent leaks we aim to get out the same day you call.
- 2. Written scope and estimate. You receive a detailed written estimate covering roofing materials, tear-off layers, flashing, ventilation, disposal, cleanup responsibilities, and how decking replacement is authorized if we find it. You approve before anything starts.
- 3. Permits and scheduling. Where the scope requires a permit, we handle the application through Oregon’s e-permitting system and schedule your roofing project around the forecast. Roofing work books up in spring, so earlier calls get earlier dates. We tell you honestly where you sit.
- 4. In-house crew installation. Our own roofing crew does the work, with your property protected first. We cover landscaping, stage roofing materials safely, and keep the site controlled. Rain can affect the schedule, and if weather shifts we protect exposed areas and let you know, rather than pushing ahead unsafely.
- 5. Final walkthrough and cleanup. We finish with a thorough cleanup, including a magnetic nail sweep across the grounds, then walk the completed job with you so you sign off on work you can see.
Weather delays are part of roofing in a wet climate, and we would rather tell you a date may move than promise a dry window we cannot guarantee. We would not count on a stretch of sunny days in a Northwest winter, and neither should your schedule. Clear expectations are the whole point.

Roofing in Lake Oswego: Neighborhoods, Permits and Climate
Lake Oswego’s housing changes block by block, which is exactly why an on-site inspection beats any citywide assumption about your roofing needs. A pre-1900 home and a 1980s infill house can sit on the same street and need entirely different systems. The sections below cover what that means for your neighborhood, your permit, and your property. Homeowners across the Oregon area and into Southwest Washington reach out to us for this same reason.
Neighborhoods and Housing Stock We Serve
We serve roofs across Lake Oswego’s full range of eras and architecture, from the city’s oldest blocks to its post-1965 developments. Here is how the housing shapes the work.
First Addition and Forest Hills include homes dating to before 1900, with Gothic, Prairie, Tudor, Craftsman, bungalow, and ranch forms side by side. Twenty-foot alleys run behind many properties, giving rear access that changes how we stage and deliver roofing materials. These blocks call for matching the roof design to the existing home, not dropping in one generic system.
Lake Grove centers on the Boones Ferry Road corridor, with Madrona Street and Spring Lane as local reference points. It mixes mid-century housing with newer infill, so ventilation and low-slope transition details can differ from one house to the next, and residential access often comes off busier streets.
Palisades and South Shore began with a 1926 plat near the lake, followed by significant late-1940s development around South Shore Boulevard, Greentree Road, and Glen Haven Road. Lake-adjacent exposure, mature vegetation, and hillside access make staging and property protection real concerns, and expanded homes bring more valleys, chimneys, and custom roof intersections that shape any roofing project.
Mid-century homes concentrate in Lakewood, Evergreen, Uplands, Palisades, Lake Grove, and the Country Club and North Shore area, where preserving horizontal rooflines and handling low-slope transitions, skylights, and chimney flashing matter. Neighborhoods like Mountain Park, Westlake, Westridge, and Oak Creek were largely developed after 1965 and carry comparatively little earlier stock, which means late-20th-century roofing assemblies and, in some cases, attached housing where you should confirm whether the roof is yours or the association’s before requesting work.
Permits and Building Code
In Lake Oswego, a building permit is expressly required when all old roofing is removed and new sheathing is installed. The city’s language does not make a permit automatic for every ordinary shingle replacement, so the trigger is the sheathing work. Any scope involving decking replacement, framing, or altered roof geometry should be confirmed with the Building Division before work begins. All roofs must be structurally sound and watertight under code, and roofing work has to meet local building code requirements.
The City of Lake Oswego Building Division issues these permits and runs its Permit Center at 380 A Avenue, Lake Oswego, OR 97034. The city participates in Oregon’s full-service e-permitting system, which handles applications, permit-status checks, and inspection scheduling online.
On fees, Lake Oswego does not use a flat residential reroof charge. Structural permit fees are valuation-based, with a 2026 minimum structural permit fee of $102.82 and a plan-review fee of 65% of the structural permit fee. The city also applies a 12% state surcharge to permit fees and a $31 record-retention fee to permits. Because the total cost depends on declared valuation and which reviews apply, we do not quote a “typical” permit figure without your project details.
Timing depends on scope and city workload. As of July 2026, the city estimates two to three weeks for the first review of residential structural permits. For inspections, requests received before 7 a.m. may be performed the same day, while later requests are generally scheduled for the following business day. We factor this into your schedule so the permit timeline does not catch you off guard.
Trees, Terrain and Protecting Your Property
Protecting your trees, landscaping, and property is part of the job here, and in Lake Oswego it can also be part of the permit. Where development activity may affect trees, the city may require tree-protection measures, an application, and a city inspection before it issues the building permit. That applies directly to material delivery, dumpsters, lifts, and access on wooded lots. Updated tree regulations took effect on October 1, 2026, so current application forms matter.
The terrain itself adds real staging challenges. Steep wooded slopes, gullies, ravines, and lake and river corridors mean limited room for dumpsters, harder driveway and hillside access, and heavy tree debris on shaded roof sections. We plan material staging, debris containment, and access before the first delivery.
The wet climate also drives how we build the roofing system. Proper flashing and ventilation manage moisture so water stays out when the surface is tested all winter, and proper attic ventilation is critical for controlling trapped moisture in a climate like this one. Before work begins we cover driveways and landscaping, protect windows and siding, and finish with a magnetic nail sweep so your grounds are safe to walk. Beyond roofing, our crews also handle window installation and other exterior upgrades when a home needs more than a new roof.
Frequently Asked Questions
Do I need a permit to replace my roof in Lake Oswego?
A permit is expressly required when all old roofing is removed and new sheathing is installed. If your project stops at the surface and does not involve new sheathing, the city’s wording does not make a permit automatic, but you should confirm your specific scope with the Lake Oswego Building Division. The permit fee is valuation-based rather than a flat reroof charge, so the final amount depends on your project. We handle the permit process for you where one is required.
How much does a roof replacement cost in Lake Oswego?
There is no honest citywide price, because roof size, pitch, access, material, tear-off layers, flashing, ventilation, and decking condition all set the number. That is why homeowners comparing roofing contractors should be cautious of any flat quote given sight unseen. We give you a free, no-obligation inspection and a detailed written estimate covering roofing materials and cleanup, and we encourage you to request multiple written estimates so you can compare what each one includes.
Can you repair my roof instead of replacing it?
Often, yes, and we inspect first to find out. Our roofing services cover installation, repair, and maintenance, and we recommend a roof repair when the damage is isolated and the surrounding roof is still serviceable. We recommend a full replacement when deterioration is widespread or a repair will not hold up long-term, and roof maintenance when the roof is sound but needs cleaning, moss management, or monitoring. You get the honest answer, not the biggest job.
What happens if you find rotten decking after the old roof comes off?
Decking condition and how replacement is authorized are addressed in your written scope before any work starts. A detailed bid outlines the scope and total cost, including how we handle concealed rot, so if we find damaged decking under the old roof, we show you, explain it, and get your approval before we proceed. That is the no-surprises standard we commit to in writing.
How long will the job take, and what if it rains?
Most roof replacement projects run one to three days once scheduled, though size, pitch, access, and decking repairs change that. Where a permit is required, the first review currently runs two to three weeks, so we build that into your timeline early. Rain can affect scheduling, and if weather shifts we protect exposed areas and adjust rather than pushing ahead unsafely. Weather delays can move a date, and we tell you honestly when they do.
Can you match the roof on an older or historic home?
Yes. On a designated landmark or contributing resource in Lake Oswego, replacing with the same roofing material, or a material in character with the original, can qualify as maintenance or repair. A visible material change may require Planning review first. We help you choose a roofing system that fits your home’s architecture and keeps you aligned with the city’s historic rules.
