Expert Residential Roofing in Portland Metro & West Linn Areas

Kenai Construction handles residential roofing for Beaverton homes, from full replacements to targeted repairs and inspections. Beaverton averages over 40 inches of rainfall annually, and the city's tree canopy creates moss-friendly conditions that shorten roof life when left unchecked. Many homes in Beaverton were built in the 1970s through early 2000s, meaning a large share of the housing stock is at or near the end of its original roof's service life. Our process covers a full roof assessment first, checking shingle condition, flashing integrity, decking health, and attic ventilation before any work begins. We identify whether a repair adds meaningful life or a full replacement is the right call. Every project accounts for the specific pitch, age, and exposure of your home. If your roof is showing water stains inside, curling shingles, moss buildup, or granule loss in the gutters, contact Kenai Construction to schedule an inspection.

Residential Roofing FAQ

Common questions about residential roofing in Portland Metro & West Linn areas.

A repair is the right call when damage is localized, such as lifted shingles or a failed flashing section. Kenai Construction inspects your Beaverton roof and gives you a clear recommendation based on shingle condition, decking health, and how much of the surface is affected.

Water stains on ceilings, curling or missing shingles, granules collecting in gutters, and visible moss patches are common signs. Beaverton's wet winters can push small problems into larger ones quickly, so early inspection matters.

Yes, moss holds moisture against shingles and accelerates deterioration over time. Beaverton's shaded yards and long damp seasons make moss one of the most common causes of premature roof failure in this area.

Yes, we start every project with a full roof inspection in Beaverton before recommending any work. We check shingle condition, flashing, decking, and ventilation so you have a clear picture of what your roof actually needs.

We service the full roofing system, including shingles, underlayment, flashing, ridge vents, and decking. Beaverton homes with chimneys, skylights, or complex roof lines get special attention at those penetration points where leaks most often start.

Poor ventilation traps heat and moisture in the attic, which breaks down roofing materials from the inside out. In Beaverton's climate, where damp winters follow hot summers, ventilation directly affects how long your roof lasts.

Greg Furbee Google review · August 2026

Bryan and his team did a great job painting my house. I received multiple quotes; I chose Kenai because I felt they listened to me and shared the aesthetic of the job. When it was done, I was really happy. My house looked brand new! Bryan paid attention to the small details, and it felt great to see a bright, clean house every time I came home.

Paul Google review · August 2026

Got job done on time and a little below budget. Roof looks amazing. Didn't charge me to put gutter guards back in. Cleaned up yard better than when they started. Excellent all around job

Brian has been great to work with. We started working with him when we had some mold issue and his team could help fix the exterior of the house. We already needed a roof so we utilized him for that next. Months later I realized there was some nails left on the roof and gave him a call. He said no issue he would have someone over to clean them off. His care for his workmanship goes even further than that as when we had some gutters added they called out some boots that needed replaced. I called him up and even though it had been a couple years he fixed the issues. He has painted our house helped added a back patio and is our go to builder.

Bryan and his team were very responsive. They spent a lot of time answering our questions and providing options. We were having a mystery leak around a window and after some exploration determined our roof was compromised. I felt great about their attention to detail, follow-up and invoicing process.

Helen McKee Google review · July 2026

After multiple estimates I chose Kenai Construction because he was so helpful before I even asked for an estimate. My roof was leaking and he came and put a tarp down, cleaned out my gutters and did it just because he is kind. After meeting with other people, it was obvious that Brian was honest in his assessment and gave me a very fair price. He not only replaced my roof but also removed the rotting skylight, fixed my kitchen ceiling and put in recessed lighting. At the end of the project, my final bill was less than the estimate and that never happens! I highly recommend this company!

Michelle Mathes Google review · July 2026

Prompt, professional and friendly service at a great price. The roof replacement only took a few days and they left the place clean. Very happy with our experience from start to finish!
