Why Portland roofs fail the way they do
Portland has the oldest houses in the metro. A lot of them went up between 1950 and 1995, and a lot of those roofs are 18 to 25 years old right now.
42 inches of rain a year end up somewhere. Moss shows up on the north side, someone sprays it every year, and nobody opens the attic hatch.
The crew comes up from our shop on River Road in Keizer. Same trucks, same red shirts, every job.
What we do differently
Your roof doesn't tell you it's failing. Your attic does.
On the roof, we measure every square and photograph the pipe boots, flashing, valleys and vents. The places cheap jobs leak first.
In the attic, with a light and a camera: moisture, mold, ventilation, insulation, daylight through the deck. Nobody else goes in.
In your hands within 24 hours: the Attic-First Roof Report. Photos, video and a straight answer. Yours to keep, whether you hire us or not.

case scenario and another based on their best estimation after an inspection. No other roofing company gave me the same care during the bidding process.” — Jenn Lackey NikiApril 2026 No pressure, no salesy vibe, just straight-up honest and helpful. He walked me through what needed to be done, explained things in a way that actually made sense, and was always quick to respond. He kept me updated, showed up when he said he would, and made sure the job was done right.
Cindy MeyerJune 2026 Black Diamond Roofing did a complete tear off and replacement of my shingle roof. I got bids from 8 companies and Black Diamond's bid was in the middle but the warranty they offer was exceptional. The project took 2.5 days. They did a fabulous job on the roof and left the property as clean as they found it. I would definitely recommend.
Kevin BiggersApril 2026 My experience with Black Diamond was fantastic. I went with them after getting a number of bids. The product they use and the addition of a ridgeline vent set them apart and they were also cheaper than some of the other quotes I got. The installation crew was fantastic and completed the entire project in 2 days, even after being down a guy on the first day. All in all,a great experience.
Eddie BrambilaFebruary 2026 I had a leak coming through a pipe flashing on a cold, windy, rainy night in January. I called Black Dimond Roofing at 7 PM, and Rodrigo had his team at my house by 8:30 PM. They quickly identified the issue and secured the area with a tarp that same night. After comparing their quote with three others, I found them very reasonable. Most importantly, Rodrigo showed up when I truly needed help. I highly recommend Black Dimond Roofing.
Jim DunsheeJune 2026 Great job, they more damage than expected and kept us updated on all the necessary repairs I would recommend Black Diamond to anyone who is wanting a quality roof
Cheri PapiniApril 2026 Blackb Diamond Roofing and their staff did an excellent job on meeting their deadline, quality of their work and clean up after completion.
Fernando Lopez2025 Black Diamond came out to give me an estimate on roof replacement, it's something I had been wanting/needing to do for a bit. They were able to work with me and my time lone to get it done. They were professional and very helpful. My roof looks great and I am glad I don't have to worry about that for the next 30 years.😅 Thanks BDR Team.
Michael Hseih2025 Had the free inspection appointment from a cold call since they were coming to the neighborhood to work on a neighbor's roof. Erick Cruz was the one that came. He was punctual and clear in communication on ETA ahead of the appointment, gave me an honest feedback on the status of my roof, and some tips on safety if I'd want to go on the roof myself. Overall had a pleasant experience with Erick and Blackdiamond roofing.
