"Long story short, hire Raindrop Roofing NW if you have a roofing job you need done right, consistent with manufacturer’s instructions. By contrast: the outfit that replaced the roof on our Dutch Colonial for the previous owners cut corners on the steep mansard slopes. As a result, the new roof which should have lasted 25 years, started failing in three. (I’ve been repairing drooping shingles ever since and have had to learn more about roofing than I ever envisioned or desired.) A few years back we hired a local company with an Angie’s List A-rating to re-shingle the problem slopes, but we had to let them go when we caught them taking the same shortcuts that caused the first roof to fail. Their excuse: the manufacturer’s instructions were excessive. (Yet these were the same instructions they had previously agreed to follow.) It’s worth noting that roofing product warranties are almost always dependent on installation consistent with manufacturer’s instructions. Nonetheless, it took several years to find another company that would agree in writing to do so at an uninflated price. Given the above experiences, we worked closely with Raindrop and watched their work with an eagle eye. They did everything we asked for and beyond! This included making extensive improvements to the roof’s ventilation, especially in the steep mansard regions. Further, the Taylor Metal standing-seam system they applied to the garage and patio looks and functions great. Their final price was consistent with their estimate, and right where it should have been given the size of our house and the materials requested. (Unlike many of their competitors, Raindrop doesn’t gouge the homeowner for requesting standing-seam metal in addition to composite roofing.) Bottom line: next time you’re walking down a street in Portland, look for the abundant tell-tale signs of roof repairs – visible patches of replacement shingles. It’s perhaps not surprising that in this sustained building boom, quality installation at a fair price is hard to come by. I'm happy to report Raindrop is the welcome exception."

"Pfeifer Roofing is courteous, professional and prompt. I was given a free evaluation of my roof, shown samples of the products they use and pamphlets for their policies and products. The free estimate was detailed with multiple options for various avenues for next steps. The installation foreman and crew itself were incredible and communicated with me multiple times throughout the four-day roofing/gutter install, sharing their noticings while working and asking me for my input and preferences. They worked hard to clean up after each day, and the final result is fantastic."

"Ricardo and his team are the best! We originally hired them to clean the moss off our roof. They were the only ones who got on the roof before providing a quote which was lower than all of the others we received. Ricardo took pictures to show us what was going on up there. After cleaning the roof he let us know about concerns they encountered while doing the job. He gave us his opinion and some options which included repairing the roof or replacing it along with the pros/cons of each. After they finished cleaning the roof we hired them to replace part of our fence. Once again, excellent job! A few months later we contacted Ricardo for quotes to repair or replace the roof. He once again provided us with fair quotes. We decided to replace the roof and Ricardo and his team started the job the next day. Once the shingles came off, the team found that some of the plywood needed to be replaced and most of what was up there wasnâ t nailed down properly. Ricardo kept us informed about other things they encountered and provided pictures and recommendations along the way. We really appreciated the thoroughness of the job they did and their attention to details. We are positive Ricardo and his team have saved us money in the long run. And we loved that they took pictures of everything as they encountered issues. The customer service, responsiveness, work ethic and thoroughness are outstanding. We will definitely hire Ricardo and his team again and will highly recommend them to anyone who has construction work that needs to be done."

"Rufus Aylwin and Aylwin Construction have been operating for years in the Portland area. We find they are easy to work with. This was the second time Rufus helped us out. He was strongly recommended by a friend and Realtor. The roof was leaking and Rufus immediately sent members of his team to tarp the leaking part of the roof It was an old roof and overdue for replacement. The new roof was applied after installing several damaged plywood sheets. We no longer live in the Portland area so this had to handled long-distance. We have confidence in their professionalism."

"We hired A&E construction and painting to put on a new roof, paint our entire home exterior, and install new gutters. Their bids were significantly lower than all others and they worked with us on our timeline. They were respectful of our budget and didn’t push us to do more than was necessary. We upgraded the vents in our roof for a very reasonable price. The neighbors stopped by frequently to comment on how wonderful it looks! I’m now hiring them for some inside work. I trust them to do quality work at reasonable prices. I highly recommend A&E !!!"
