Klam Construction was an absolute pleasure to deal with. From the initial quote by Abel to the completion of the job everything was top notch and professional. It is so rare to deal with a company as wonderful and professional as Klam. I would highly recommend them!!

Shannon A of Troutdale, OR | 2020-07-31

It was a pleasure working with Able and Katie at Klam Construction. They were great at communicating and kept me informed throughout the whole process. Able went over and beyond to make sure everything was done to the highest standards.

Great product and service

Lori E of Beaverton, OR | 2020-05-26

From the first visit from Abel to inspect the roof replacement project to the completed project, we were very happy with the overall experience that we had with Klam Construction, LLC. They were not the least expensive and not the most expensive....we selected them due to a trusted friend's recommendation as well as the thorough plan that was provided with the estimate for the project along with the professional interaction we had with Abel. I would highly recommend them for a roofing project and happy to provide a high level recommendation for them.

Tim M of Hillsboro, OR | 2020-05-20

Was given two bids with with different levels of service, both were competitive with other contractors. Chose them off good recommendation of two previous customers.

Tamara W of Portland, OR | 2020-05-20

Abel and his crew are professional in all respects; timely, efficient, hardworking and careful. Abel and Katie are great communicators and I would not hesitate to recommend this company!

Dale & Maria C of Portland, OR | 2020-05-12

The owner of Klam Constr. was extremely thorough in checking my old roof and in explaining what the new one would entail. Everything was done as promised, the workers did a great job and everything was done on time. The roof looks good and I'm glad I chose them to do the job.

Paul S of Welches, OR | 2020-05-12

Everyone at Klam Construction was professional and friendly. We are very happy with our new roof.

Niraj R of West Linn, OR | 2020-05-12

The entire experience with Abel was smooth and satisfactory. As noted by others, Abel comes across as a man if his word, and I experienced it first hand. He is very fair in his pricing, explains details of all the features, why they are needed, doesn’t oversell. He even helped put better quality gutter guards at a reasonable price when I mentioned our prior ones were overflowing. His crew is also very professional, works very hard, keeps things clean, don’t clutter around and clean up at end of every day. Abel and his team went above and beyond in helping with few miscellaneous items around the house. Would definitely recommend getting your roof done with Klam construction. We get many compliments for our new roof from neighbors.

Tim H of Hillsboro, OR | 2020-05-12

The Klam team responded to all my questions, did a great job on the shingles replacement and left the job site clean. Even painted the metal chimney to make it look new and match the new black roof.

Verna L of Portland, OR | 2020-05-07

We were very happy with the professionalism of Klam Construction. He took the time to explain their process and the new roof gave our home a nice look. They cleaned up well after their work. We have no complaints at all over the work they did.

Kathy P of Portland, OR | 2020-05-07

We would highly recommend Klam Construction for roofing. Abel Serrano was thorough and complete in describing our roofing problems and needs. His foreman came on a Saturday to set everything up for the crew to start on Monday. The crew was hard-working, efficient and courteous. They finished the job in 2-1/2 days.

Nancy V of Tualatin, OR | 2020-04-21

They were extremely professsional and I was impressed at how they cleaned up every day, it was pristine. They did a wonderful job.

Joe B of West Linn, OR | 2020-04-21

Abel and his crew were professional and outperformed any of our expectations.

William T of West Linn, OR | 2020-04-17

Klam was great to deal with throughout the whole process. From the very competitive estimate to quick quality work from crews on site. We appreciate the very good experience we had with Klam Construction.

Bill K of Beaverton, OR | 2020-04-17

This was a major expense and I did a lot of research, and only considered well-recommended companies, of which Klam Construction was one. A key reason I selected Klam for the full replacement project was their detailed bid and analysis of where my roof issues were, and what was necessary to address these issues. The bid was very competitive on the dollars and cents. The project itself was commenced and completed timely, with the job site well policed every day. The core crew on my house had worked together for several years and it was easy to see they worked well together and enjoyed working together. I am happy to recommend this company without any reservations.

Sandra & Gary M of Boring, OR | 2020-03-30

Klam Construction has earned our five-star rating. From beginning to end, each Klam employee with whom we worked provided stellar service in every aspect of our roof project. They gave us a beautiful new roof in a timely manner. Everyone was polite, respectful of our property and clearly interested to provide a quality product with quality service.

Russell F of Tualatin, OR | 2020-03-25

We chose Klam from a competitive among the top rated roofing companies in our area. From the very beginning of the process, it was clear that Ablel and his team had the vision and the experience to do the job right the first time. The project was completed in the allocated time, for the bid amount. No issues at all. They used superior materials and the craftsmanship is top notch. I would recommend them without hesitation.

Bruce M of Beaverton, OR | 2020-03-24

Our 20-year roof started leaking after 35 years (go figure). I checked the Nextdoor app and asked friends for roofer recommendations, and chose three from whom to get bids. The first one took a 10-minute walk around our house and sent a bid. He didn't seem that interested in our business. The second one got on our roof and checked it out. He sent a bid that was identical to the first person's bid but warned us that there definitely would be rotten plywood underneath the shingles that would need replacing, and possibly damage in the attic, but he wouldn't know how much (and at what cost) until he started replacing the roof. I would have gone with him, because I trust the realtor who recommended him, but I wanted one more bid.KLAM Construction had outstanding reviews on several sites, so I scheduled an estimate. Abel, the owner, first did a thorough inspection of the roof. He explained where the water was leaking, where the original roofer had cut corners, and what a modern roof would consist of. Then he did an equally thorough inspection of the attic, taking pictures to show me some sheets of plywood that would need replacing, and saying that there might be more under areas of the roof that weren't visible. Fortunately, there was no other damage. He told me to add some insulation strips to the edges of the attic hatch. Then he gave me a detailed explanation of the entire roofing process, including technical details (I have an engineering background and wanted to hear them), and told me about the platinum-level warranty offered by Owens Corning. Abel's bid was somewhat higher than the other two, but the warranty more than made up for that, and the roof would some extra ventilation features that the other two roofers hadn't offered. Also, I wanted to give our business to Abel because he had gone far beyond what the other two had done in terms of his inspection and explanations.After that, Katie, his coordinator and assistant, took care of the contracting and scheduling. She was a pleasure to deal with during the entire process! We thought it would take a couple months to get on the schedule, because it was the busy (rainy) season, but our roof is simple, and there was a three-day break in the rain, so Katie was able to schedule a crew for that week. The crew was polite and professional. The process took two and a half days, and the crew cleaned up everything at the end of each day.On the last day, one of the crew members told us that he had accidentally punched a hole in our ceiling, and was very apologetic. These things happen, and Katie scheduled a ceiling-repair person to come fix the ceiling. He did an excellent job, and we can't even tell where the damage had been.Our new roof is beautiful! I can't recommend KLAM Construction highly enough. I'd use them again if my wife and I ever need a new roof, but if we stay in this house, the roof will outlive us. :-)

Cary & Cathy G of Portland, OR | 2020-03-24

We were extremely happy with Klam and their employees. Their knowledge and experience in the roofing industry is very evident. The staff was wonderful to work with, from initial quote to final inspection. We were impressed with their attention to detail and organization on-site. We would definitely recommend this business!

John P of Portland, OR | 2020-03-24

They did a wonderful job!

Seth S of Portland, OR | 2020-02-24

I was so happy to have found Klam Construction. After taking bids from several other companies that often failed to fully address our roof's ventilation issues, we got a complete bid and a well explained proposal from Klam Construction. Our small roof needed a lot of work and it was done to a very high standard. The "designer" shingles that we choose look great. We were happy with the process from start to finish.

Klam Construction is probably one of the most professional companies I have worked with in 45 years in the construction industry.

Response from Klam Construction LLC

Ben M of Portland, OR | 2020-02-19

Klam construction is the best. Abel, Katie and the team are fantastic. No-brainer, Klam should be your roofer

Response from Klam Construction LLC

Thank you for sharing another KLAM success story. "Our customers are the heart of our business. Without them KLAM would not exist, so we work very hard to take care of them, to answer their questions, to keep them informed on their job’s progress, to make sure they are happy with their new roof." - Abel. Thank you for choosing KLAM

Brian T of Portland, OR | 2020-02-03

I received 3 estimates for my roof. Abel spent the most time of anyone and provided the most detailed description of the project. He even noticed we'd had problems with squirrels and addressed how he would squirrel-proof my roof. When the 3 estimates came in, we were pleasantly surprised that Klam's was the lowest. Based on how much time Abel had spent with us and the warranty offered, my wife and I assumed Klam's estimate would be much higher than the others, and I would have been willing go with Klam if it had been a little higher than the others. They offered the best warranty by far with no extra cost. Klam contacted me 1 month earlier than they estimated to let me know they were ready to schedule. When the weather delayed the first day of work, Katie left messages keeping me appraised how they intended to proceed. The crew did a great job tiding up after the work was done. Overall, I'm very happy with Klam Construction.

Response from Klam Construction LLC

Thank you for your business and your review. Glad we achieved our goals of another happy customer. - KLAM

John & Gail J of Gresham, OR | 2020-01-31

Abel provided us with the information that we needed to make an informed decision and never brushed off any of our question or concerns. The job was done quickly with a minimum of disruption. The cleanup afterward was almost perfect and when one piece showed up later, they came promptly to verify that everything was okay.

Easily the best decision we've ever made in the contracting/home improvement area for our home. From Abel to Katie, plus every employee in between, total professionalism, reliability, and quality. A roof is a large and expensive project (we received five full bids), and we couldn't be happier we chose KLAM! You won't be sorry if you do too!

Response from Klam Construction LLC

Greg, Thank you for taking the time to give us this review. And we are glad to have you as another happy customer. Thank you for choosing KLAM to handle your roofing project. Enjoy your new roof. - KLAM

Steve M of Oregon City, OR | 2019-09-20

I had three companies come out to give me a quote and feel very fortunate that Klam was one of them. Abel was the only one to go up into the attic and educate me on venting problems that are common to homes of the period of which ours was built. They didn’t just put on a new roof, they upgraded what would eventually become underlying problems.

Response from Klam Construction LLC

Abel takes great pride in being thorough. We want nothing less then a quality roof at a fair price and happy customers. Thank you for choosing KLAM do handle your roofing project and for taking the time to give us this review. - KLAM

Peggy S of Portland, OR | 2019-09-12

I was so pleased with this team that replaced our roofing, was impressed with the care they took to protect plants, and bushes around our house, even forming a wooden tent over container plants in front. Each night the grounds were gone over all debris picked up, finding only 4-5 nails totally hidden in one area. Totally amazed & so appreciate the time & care taken. The end results look so good, and have brought rave reviews from our neighbors. The ole adage “you get what you pay for” is once again proven true???? Huge kudos to Klamath Construction.
