"Pfeifer Roofing is courteous, professional and prompt. They provided a free evaluation of my roof, showed samples of the products they use and pamphlets for their policies and products. The free estimate provided various options for next steps. The installation foreman and crew itself were thorough and communicated with me multiple times during the four-day 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 amazing. I certainly recommend their service."

"These workers were so professional it was a joy having Antonio, Willie and Alejandro here. They came prepared with a trailer and their gear. They even had their own port-a-potty!! Clean cut, hard working, worked their butts off with smiles on their faces. These fellows worked from the time they got here until it was time to leave AND they cleaned up after themselves EACH DAY leaving the yard looking pristine. As bad as it was finding out I had a river running through my attic and a ceiling coming down in a bedroom due to this leak, necessitating a new roof (Raindrop DID NOT install the old roof!), I was actually sorry to see them go. I can't thank them enough. And the job looks great. Even the neighbors say so! And a thank you to Tony, the supervisor. He would stop by wanting to make sure the job was to my liking. Questions or concerns just call him. I really appreciated his customer service! And last, thank you to Mac from Hammer and Hand who recommended Raindrop in the first place. They were a wonderful company to do business with."

": Professionalism, Punctuality, Quality, Responsiveness, Value Please please please do yourself a favor and recommend this gentleman to anyone looking for full roof replacement, repsairs, gutter cleaning, installation, power washing services, etc. If you'd need a personal reference please do contact me. First off let me first say that I am a stickler when it comes to business professionalism and their conduct and responsiveness and this company absolutely exceeded every expectation I could have had. Ramon is a delight and a pleasure to work with he is professional, responsive, upfront very transparent and gives you any kind of option that you might need to get the project done. He was able to complete my roof for a very reasonable price actually lower than a lot of competitors in the area. Ramon's company is locally based in Scappoose Oregon and he uses local folks for his Services. I love and appreciate that he uses folks from the area as well as products from the area like Malarkey Roofing which is manufactured right here in Oregon. His crew was able to do a complete tear off and install of my roof in one day! With only some final touch-ups needed the next day because it simply became too dark for them to see and be safe. I was having a couple days where my brain wasn't obviously working quite right and he was ever so patient with me regarding the quote that he had given me that was VERY clearly written in black and white yet I misread it. I had a myriad of odd questions and never once did Ramon not give me his full attention to answer questions in person, text, phone or email. His crew also did power washing for me as well as gutter services and I could not be more pleased his company truly embodies the quote-unquote spruce up factor and while it's not listed on their services it should be because his company does actual full roof installation. I hope that he adds this to his website because it's definitely a service that is to be recommended and commended. Services: Power/pressure washing, Gutter cleaning, Roof replacement"

"My experience with Aylwin Construction was 5 stars. They did the job in just three days and added copper-beaded shingles for moss control for only $100 more. Alywin's Crews were on time and cleaned up as they went, provided protection for our plantings, and did a complete sweep for nails and other debris when finished. My family is looking forward to having Aylwin do a full replacement this year or next with a full Tesla Roof. I was completely surprised to read the recent review regarding the quality of work done by Aylwin Construction at a local condominium. Over the past 20 years, as an owner of one of Portland’s larger boutique industrial real estate firms, I have recommended Aylwin Construction to my biggest and best real estate investors. Making a poor recommendation would reflect poorly on me and my company. I have recommended Aylwin Construction to friends with structurally difficult Mid-Century solid deck roofs, large REIT buildings throughout Oregon and Washington, medium Family-owned apartments, and my own family members for roof cleaning, on Mt. Hood, new gutter systems, and full roof replacements and repairs. Multi-million-dollar Multi-Family jobs have been completed Professionally and on time without fail. Aylwin their own fleet of dumpsters and roof cranes that protect the property, speed up projects, and reduce on-the-job injuries.

"We received 4 bids to replace our front porch roofing and Mike offered us advice that no one else did. The finished roof is absolutely what we wanted, and his crew of professional roof installers were fantastic! Mike and Pacific Ridge Roofing will be our go to company for any future roofing needs."

"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 !!!"

FAQs for flat, foam, or single ply roofing installation and replacement projects in Portland, OR

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
