"Javier and team did an amazing job with our roof replacement; very timely, efficient, and professional. New vents were installed, and they took the time to replace a couple beams that were rotted out. Including painting. We are very happy with our roof & highly recommend J Roofing LLC. Thank you, guys!"

"Their assessment of our issue felt pretty comprehensive and their price to Fix It seemed pretty fair for what they offered. They were efficient in their timeline without feeling overly pushy about making a sale or anything and they have offered us a very solid warranty, especially important given the problem we needed to help with is one we first thought we mitigated last year. Honestly will have to see if there's still any leaking going on, since that's just the way Portland is, but as of yesterday, at least on the initial stuff everything was completed in a manner that seemed comprehensive and effective."

"Ricardo Gallegos responded quickly to my request to bid on a low slope PVC membrane roof repair. His bid was reasonable and clear, better than several other companies. The Job: My roof was installed incorrectly around the chimney by the original installer which caused the decking underneath to rot out. Ricardo repaired the roof in September 2025 and I am writing this review in December 2025 after several very rainy days and am happy to say the job is holding up very well! It was a very pleasant experience working with Ricardo and United Construction, I highly recommend them!"

"Osiel and his crew work hard, hardest I’ve seen. As a real estate sale professional, I’ve come to rely on having a team of professionals that can be there when I need them. Osiel has proven invaluable in his expertise, experience and a calm approach to some pretty difficult jobs. No hesitation on who I’d call when it comes to roofing! 👍🏻"

"My roof needed to be replaced and I had four contractors come look at my house. Not only was Matt the only one who did not insist on talking to my husband, he was professional and gave the lowest bid. If you are a woman looking for repairs or a new roof, this is the best company in Portland! We are very happy with the roof and now that it has better ventilation my house is much cooler! They also got the roof done within two weeks of signing the contract while we were out of town on vacation, so bonus points for being fast and convenient!"

"Got it done promptly and on schedule but costed more due to needing more siding materials which I authorized. Challenges with matching color between new and old siding, as expected. Wish there were better industry solutions for color matching, but hard to replicate weathering. "

"The tear off and install took a week which was longer than we expected."

"Jon and his crew came highly recommended from our friends and neighbors, and they are the best contractors I've ever worked with. We have had an extremely difficult leaking issue with our roof, which multiple companies have attempted to fix. When the leak came back during Portland's sudden monsoon rains, Jon dropped everything and came out to do a quick patch. When that didn't work, he came back two days later with a co-worker, on zero lead, to find the leaks and do a full reshingling. The two cheerily worked into the early dark to fix the roof that day. His rates are by far the best we've seen, and he's just naturally a gregarious guy and an obvious good person who will do whatever it takes for his customers. That's the kind of contractor I want on my side and I cannot recommend him enough."

"Great! The team were punctual, professional, courteous, tidy AND great value for money. They could also get the job done months before other companies I called."
