Customer Reviews

"I would not recommend Oswego Roofing because it took over a year to obtain the GAF guarantee as promised."

"They repaired my chimney and roof. Very professional. Did the work in a timely manner. Cleaned up and the job looks excellent. I recommend them highly and without reservation."
"I have used this company in years past and the service has always been good. I understand that they have changed hands and now their customer service has gotten awful. They never returned my phone calls. When a neighbor scheduled service from them they never showed up."
"The entire experience working with Oswego Roofing was positive. Nephi was great to work with helping us determine the best solution for a new roof. The roofers did an excellent job - they were on time, extremely hard working, pleasant to have around and were respectful of our property. Highly recommend them."

- "I'm biased because I work here! But I can't say there's any place I'd rather work! Hardest working bunch of people I know(family)! We're not above making mistakes! But we own them! And we will do what it takes!"
- "Oswego Roof has been great this past year. We purchased a home in West Linn and sold a home in Oregon City. Oswego Roof gave us honest feedback on the status of the roof on our home we sold in Oregon City after the buyer's inspection turn up issues prior to the sell. On the home we purchased in West Linn they were great to work through in the bidding, selling, and installation phases of our new roof. Hats off to Nephi Bahr and the Oswego Roofing team."
- "Oswego Roofing replaced a failing roof system on my two story home. They worked hard, showed up on time and delivered a great job. They left no scraps or construction debris and were pleasant and eager to answer all questions. I'm happy to have selected this excellent company for my roof project."
- "Looking for a new roof? A roof repair? Upgrade? A fair price? I saw Oswego roof put a new topping on a nearby home, and I was impressed with the workers, the workmanship, and the final result. So I hired them to do their magic on the roof of my 115 year old farmhouse. I could not be happier with my decision. If you're in the market, look no further!"
