Good price, quality workmanship, job done on time, everything cleaned up and no damage to my plants. Prettiest new roof in the neighborhood.
Our Work
Real roofs across the Portland metro. No stock photos.
Every photo here is a house we worked on. Including what we found in the attic first.
Before & after
Same roof. Same angle.
Every pair here is the same spot on the same house. Look at the edges and the lines, not just the color.

The work
Before you judge a roof, know what to look at.
These are our jobs. Read the captions, then look for the same things in any other roofer's photos.
Comp roofsThe standard roof in the Pacific Northwest.
Full tear-off and new comp system. Clean ridge, new chimney flashing. 
Comp replacement on a 1990s two-story. 
Comp over brick and siding. Drip edge and gutters reset. 
Steep pitch, three planes, one continuous ridge. 
Two gables and a shared valley. 
Older home, full tear-off down to the deck.
Details worth checkingThe parts a cheap bid skips.
Ridge venting balanced for 42 inches of rain a year. Ask any roofer to show you this. 
Valley and dormer. Ice & water shield runs underneath, where the water goes. 
New flashing, not reused. This is where cheap jobs leak first. 
Architectural grade up close. Thicker than a 3-tab, and it shows.
On the jobWhat it looks like while we're there.
Red shirts so you can see everyone from the street. Harnesses on the roof. 
Material delivered to the roof, not dragged through your yard. 
Disposal handled. Magnet sweep before we leave. 
From the ridge on install day. You get photos like this the same day.
How to read a roof photo
Any roofer can show you a photo of a finished roof. Here's what to look for in ours, and in theirs.
The ridge cap
Is it a double-layer cap, or a single cut shingle? A single cut shingle on the ridge is the visible tell of a cheap bid.
The pipe boots
New boots and new flashing, or the old jack pipes left in place? Old ones are where leaks start.
The valleys
Ice & water shield where the water runs, or standard felt? You can only see this in a photo taken during the job. Ask for one.
The ventilation
Intake at the eaves and a ridge vent on top, or nothing touched? Ventilation is the #1 reason roofs in the Pacific Northwest die early.
The decking
Ask for the photo of the rotten sheets before they came out. If there isn't one, ask why.
What people say
Reviews from these roofs
Sherri Stearns2023 Kevin BiggersApril 2026 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.
Israel J Bynum2023 It was very cold with a strong wind and a mix of rain, hail and snow, but they worked extremely hard and fast to get half torn off and recovered before any water got in.
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.
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.
