We were throughly satisfied and impressed with Klam Construction, LLC, starting with Katie in the front office, meeting with the owner Abel, and the men who performed the roof replacement. From the very beginning Katie jump started the whole process, explaining the installation of the Port-a-pottie, where they would need to park the trailer for the throw aways and supplies needed to replace our roof. Klam Construction, LLC came highly recommended, however, we wanted to make sure we did our due diligence and looked at three different companies for quotes. Klam was the only company that actually got into the attic and on the roof to survey the damage. The other two companies just did a visual inspection from the street, never got on the roof or in the attic. One of the other companies spent close to three hours talking about how great their company was and basically wasted my time. Abel showed us where the problems were, what he was going to do to solve the problems, how long it was going to take, when the crew was going to show up and the process involved. Able answered all my questions in detail and I felt very informed concerning who, what, when, how. There were no "flashy" sales gimmicks, he was in the house no more than 30 minutes. The men that did the work were very knowledgeable, cleaned up each day after finishing the days work, with the roof replacement taking three days, just as quoted. We had a couple of nails that came through our roof, because of how the home was built, a portion of the interior ceiling was right up to the roof line. When I saw what was happening, I made the person in charge aware and he immediately came inside, took pictures and sent them to Abel. There was a sheetrock specialist out first thing the next morning and repaired the damage. Once the job was complete, Abel came out and got on the roof to inspect the work performed. Abel then sat down with us, explaining the warranty, and basically "what's next" and not to hesitate to call him right away with any issues that may pop up. Ultimately, the decision to go with Klam Construction, LLC was based on their detailed information concerning the problems with our roof, how they would correct the problems, their professionalism starting with the front office, Abel the owner and the men who worked on the roof replacement. I cannot say enough good and we would most definitely recommend Klam Construction, LLC for any of your roofing needs. I dreaded dealing with the roof replacement and Klam Construction, LLC made the whole process a wonderful experience. read more

Exceptional end-to-end service, support, and quality! We recently had Klam Construction do a full roof replacement on our home that also included replacing all of our skylights. I can't say enough how incredible Abel, Katie, and the entire Klam Construction crew was from beginning to end. From the very start, Abel showcased a level of knowledge & expertise, attention to detail, and sheer pride in his work, that all truly stood out when compared to the other bids we received. That was then coupled with a world-class level of support and follow-up provided by Katie (clear & transparent details in the bid/pricing, quick response to all our questions, and an incredibly genuine & honest level of communication), which made the rest of the bidding & commitment process seamless. When it came to the project itself, WOW!...as we were blown away by the level of skill, craftsmanship, and efficiency the entire Klam crew displayed. From start-to-finish, the highly skilled Klam crew met every milestone and expectation in a very timely manner. In fact, they were able to finish the project a bit early, without compromising any quality, to help avoid rain that had unexpectedly come into the forecast for the last day, which we so greatly appreciated! It was also very clear that prioritizing the protection of our property (and neighbors' properties), and overall safety, throughout the project was of utmost importance to the crew. They also did a fantastic and thorough job making sure all of the demo, debris, and total work site was cleaned up throughout the project (our property was spotless, actually looked better after the project than it did before!). Most importantly, there were zero surprises throughout the project, and Katie checked in consistently to provide added updates and details as the project progressed. Overall, we are SO happy with our new roof and skylights! The quality is out of this world and we've already had every one of our neighbors compliment on how incredible our new roof and skylights look! Again, I can't say enough how thankful we are for Abel, Katie, and the entire Klam Construction crew! Thank you Klam, you've definitely won a lifetime customer and endorsement from us, we appreciate you so much! read more

We had about 5 different roofing companies come out and give us bids on a new roof. My friend had Klam Construction do his roof and highly recommended him. Abel with Klam Construction came out and spent over an hour on the roof and inside the attic looking to see what exactly what we were looking at. After his inspection he spent time explaining what was needed and recommended. He was the only one, out of all the contractors to do this. To me, this means he cares about what his company does and what his potential customers want. Roofs aren't cheap. We got all the bids in and talked it over and decided to go with Klam Construction. Mind you, they weren't the cheapest, but as soon as Abel left I knew it was his company that I wanted to do our new roof. They were out about 4-5 weeks out when we signed the contract. They showed up exactly the day they said at about 7:30 am and started work. They worked that whole day in 95+ degree heat until about 8:30 pm ripping off and replacing a bunch of sheeting that needed replacing. I think they replaced about 30 4x8 sheets of plywood. So it was a significant tear off and replacement of bad sheeting. Our yard and property looked like a tornado hit it that first day. I left for work at 2am the next day and was on my way home at about noon when Katie called and said that they were done and cleaning up. I couldn't believe what I was hearing. Because when I went to bed at 6pm, I could see sky through a huge portion of my roof, from the garage, not my bedroom lol. I got home about 10 minutes later after Katie called and they were gone. I couldn't believe what I saw, my roof looked incredible and my yard and property on the sides of the house were left in better condition than from when they got there! I was absolutely impressed!!! They even raked the bark dust in the dog run. Everything was back in the exact place they moved it from. We definitely highly recommend Klam for your new roof. What a great experience with Abel and his company. Thank you to everyone that worked on our project. read more

We had our 27-year-old cedar shake roof replaced by Klam Construction in June. Owner Abel personally came out to inspect our roof and give us a quote. While inspecting the attic he noticed several things that were not up to code when the roof was installed. We got 5 quotes and Abel's quote was the most detailed, including list of all materials and services necessary for the job. Although Abel's quote was not the lowest, it was a fair quote and unlike a couple other roofers who pressured us to commit that day for a lower price, Abel gave us quotes for 4 options that were good for 2 weeks with no pressure to sign immediately. He also did not push more costly options that other roofers did and explained to us why they were not necessary for our roof though he would gladly upsell us if we really wanted them. We have a large roof which took 5 1/2 days to complete. The crew consistently worked 12-hour days and cleaned up the site at the end of each day. On the first day, the crew stripped off half the roof and covered it. They couldn't work the next couple of days due to rain. Late Friday afternoon, we noticed some water leaking and called the office. Nobody answered so we left voicemail. Within 10 minutes, we received a callback that a crew was on their way to fix the leak. When they arrived, they inspected the entire attic for leaks and added additional tarps. We were very impressed with the fast response. Abel has very high standards for himself and his crews and takes responsibility if anything goes wrong. We HIGHLY RECOMMEND Klam Construction. read more

After the 30-year-old roof on our small church sprang a leak, we decided to replace it instead of repairing it. Among several companies contacted, we chose Klam Construction for the following reasons. Able Serrano, the friendly estimator and owner of Klam, did a very thorough exploration of our attic and roof. He explained to us in detail all the necessary changes and improvements, and even created a color graphic of the proposed work that was easy for us to understand. The detailed written estimate was pricewise similar to other estimates. From then on, our contact was mainly with Katie in the office, who was very responsive to our questions and emails. She was also very experienced in organizing the legal paperwork, and kept us well informed of scheduling timelines. By pulling several crews together, Able used a window in the rainy weather to complete the entire job within a short time. The crew was very careful in protecting our front and side plants. They worked very harmoniously and carefully, dedicating up to 12 hours per day, and did a fantastic cleanup at the end of the job. Altogether, it was a very positive experience for us working with Klam Construction. On their brochure handed to me at the time of Abel's estimate, it says: "Being honest, respectful and fair with people is how I like to do business." I can attest to the truth of this statement and the integrity of Klam, and I will certainly recommend them to friends. read more

KLAM was recommended to me by my sister, they were recommended to her by a neighbor. Abel, Hyram and crew did an awesome job on our roof. From the initial consultation to the final walkthrough they were excellent. Great communication with Katie at the office. After researching dozens of companies and reading literally hundreds of reviews including KLAM's I realized no other companies reviews mentioned an interior inspection of the roof from the attic. Not only did Abel go through my attic from one end to the other he took pictures as he went and showed us several issue that we would not have know about until the tear-off which would have resulted in additional cost above the original quote. We had several unusual issues - abandoned stack from a long ago removed furnace, bathroom fans exhaust exiting through roof together and fan ducting which was too long, both of which were not to code. We also had insulation blocking the soffet vents causing moisture damage. With such a thorough inspection I feel we got a more accurate quote than we would have otherwise. The crew showed up on time and called ahead as requested so we could make sure our dogs were in. They were organized, professional, helpful and polite. They respected our property and cleaned up all debris on completion. The did a very large roof in just 2 days which was amazing and beyond expectations. KL read more

KLAM Construction replaced our roof in April of 2024. They exceeded expectations in all areas. Starting with the free estimate, they were very up front about what would be needed to do the job right and discussed areas that might require additional work/expense depending on what was found under the existing shingles. And their up front rates for extra work are reasonable. After the job was complete, there were no surprises in the final price (it ended up being the quoted price for us). Due to trim and flashing they added (items the original builder should have installed), our roof is now better than when the house was first built. We have a large roof, and the demo and replacement took 2-1/2 days. The workers went out of their way to protect our paver driveway, and their final cleanup was exceptional (the area where they staged the material was cleaner than when they first arrived). I selected KLAM because our neighbor had their roof replaced by KLAM a couple of years ago. Our neighbor doesn't like working with contractors, but appreciated the experience with KLAM. I also don't enjoy the process of finding general contractors, but working with KLAM Construction was stress-free. I just wish KLAM did painting and other miscellaneous home repairs. They'd be my go-to contractor every time. read more

I interviewed 3 roofing contractors and Abel was the only one of the three that went up into our attic. There was considerable damage found there due to lack of ventilation that had not been installed when the roof was first done as new construction. Abel thoroughly explained the issues caused by the lack of adequate ventilation and what he recommended to manage the problem. We had mold on multiple sheathing boards, lifting of the edges of the sheathing where theymet up against other boards and water stains. Our roof was only 21 years old and we had been told that it was a 40 year roof when we purchased the house. If we had chosen one of the other contractors, both of whom had MUCH higher bids, when this damage was found our "change orders " would have been huge on top of an already bigger bid. Abel is a platinum preferred contractor with Owenings-Corning and he and his team are ABOSLUTELY THE BEST!!! The team and foreman are professional, knowledgeable and hard workers. The cleanup at the end of each day looks like they weren't even there! The coordinator of the work, from delivery of the dumpster to the finish day and everything in between, is super and always just a phone call away as is Abel. If you need a new roof, HIRE KLAM CONSTRUCTION WITH ABEL AND HIS TEAM! read more

Klam Construction came out on top when we researched roofing contractors on Better Business Bureau, CCB, Angie's List & Owens Corning. We did take 3 bids and all were within a reasonable range of each other. We went with Klam after meeting Abel, the owner. His enthusiasm and detailed description of the work he intended to complete were some of the selling points. He spent lots of time with us explaining the process and our options to replace our home's roof. The project is now complete. We found Klam to be a highly professional group of craftsmen who were very organized and hard working. They made sure our roof was watertight overnight and cleaned up everything each day. The communication from everyone at Klam was spot on. We were kept up to date on the schedule every step of the way. After the project was completed and the crew had cleared, Abel came back out to inspect and make sure we were happy with the work done. Having spent 45 years in the construction industry myself I can truly say that Klam Construction is a real 5 star outfit. I doubt seriously you'll find a better contractor to deal with. read more

Klam Construction owner Abel Serrano was highly recommended by our financial advisor to replace our roof. He had his roof replaced by Klam and was very impressed with the quality of their work. We are very glad that we decided to go with Klam Construction to replace our 22 year old roof as they did a fantastic job beginning to end! Abel thoroughly examined our roof and even took pictures of inside our attic which had water damage. He then explained in complete details, including drawing diagrams of how he would replace our roof. Abel is extremely knowledgeable and confident in the roofing business. After initially meeting with him, we felt confident in going with him. And he did deliver! No corners were cut and the whole process went very smoothly. And the crew were great! They were friendly, efficient and hard working! And they left our yard clean and debris free. And fact, several neighbors watching them are so impressed that they will consider Klam Construction to replace their roofs when they are needed! Thank you Klam Construction!! read more

Actually I would rate Klam constructions with a 5 plus rating as they went far and beyond the normal work of roof replacement. When Abel came out to access the job he was very meticulous and went onto the roof and inside the attic to see in person what needed to be done instead of leaving to a computerized aerial mapping and quote. He found several cases of potential leaks including a recent chimney job that left large cracks and dry rot, a set of plastic vents with cracks that he intended to replace with stainless steel, and spaces between the roof and siding that could allow pest to enter etc etc. He recommended putting gutter screens that his crew would install after cleaning the gutters. The roof tiles he recommended were highly rated yet economical. Work was completed in 3 days, just in time for the rainy season. Cleanup was exemplary and nothing was damaged. I can't recommend the staff at Klam construction enough for their professionalism and high quality work. John Flinn Nov 6, 2025 read more

I got bid proposals from a few other companies but, Abel was without a doubt the most thorough in his inspection of my attic and my roof. The other companies just sent out sales people who weren't interested in going into my attic and relied almost exclusively on aerial satellite photos. Abel was also the most thorough in explaining to me both verbally and on paper exactly what they would do, where the new vents would be placed and a few small fixes to the prior roofing job. Abel just inspired confidence and I would much rather deal with the owner directly than a sales person. The crew also did a good job daily, of cleaning everything up and not leaving one big mess to clean up at the end of the 4 days. Katie coordinated all the field work and was a great communicator. As far as the roof itself, it was very well done and I'm extremely pleased with the work. Abel, Katie and crew were great to work with. Thanks Abel. Yer the man! read more

Our experience with Klam Construction was absolutely fantastic from start to finish. From the initial reach out for a quote to replace our roof until project completion the customer service and response time was fast and very helpful. The inspection for the bid was very thorough and did not feel pushy, It was informative and felt very honest; as well as very fair priced from the other quotes we received. The crew who showed up to do the project were very kind and respectful of us and our need to come and go. They cleaned up well each day and I have yet to find even a single nail left behind. Their quote to final price did not change, which I hear is common in the industry. Overall we were very pleased with how everything went from start to finish. I would wholly recommend them to anyone looking. They are truly the best company I have ever worked with for anything in my home. read more

It was a pleasure doing business with such an honest, professional company. Abel's inspection before making the bid was thorough and his explanation of our options for the job was clear. We appreciated the education about roofs and roofing he offered. We were out of town during the work and Katie kept us informed of the process and project status. She was efficient and personable. Also, we had several neighbors watching the project and commented on the speed and professionalism of the crew. KLAM Construction came highly recommended to us by two different friends living in different parts of the Portland area, and the company surpassed our expectations (and they were high). Along with a job very well done, KLAM Construction holds itself to high standards of integrity and service. From start to finish, we were in good hands with KLAM Construction. Thanks! read more

I began my search for a new roof by getting three estimates. I was surprised by the wide range in price for the same roof. After reading all the reviews online on the BBB, yelp and other sites. One company stood out, Klam construction. I setup a estimate (my sixth) with Katie. Abel showed up, inspected my roof and attic. Abel is not just a good salesman, ex roofer but someone who believes in his company, team and product. The company was very transparent on how things would be done, and what to expect. You could tell alot of thought had go into their processes. The result was a very fast demo and installation of the new roof. At the end Abel showed up to do a final inspection himself. If your getting a new roof, I'd recommend adding Klam construction to your list of companies to get estimates. A very impressive owner and company. read more

We had Klam Construction install a new roof, gable boards, additional venting and attic baffles on our home. The whole process of working with Klam was great. Abel, the owner, spent two hours with us inspecting our roof inside and out, and also explained roof ventilation and the need for it. Katie, in the office was a pleasure to work with as well. She offered to have some materials delivered ahead of the job so that they could be painted before installation. She was also very knowledgeable in the roofing process and was able to answer my questions. The crew that did the installation was very respectful of us and our property. It was a one and a half day job. The crew was hard working and thoroughly cleaned up after leaving each day. Would definitely recommend Klam to anyone needing a new roof! read more

Klam was a delight to work with at every step of the way. We appreciated the friendly, professional, and timely manner in which they responded to any and all questions. We also appreciated Able's personable manner, the time he took to explain the process with pictures and drawings, and how he took time out of his day to drop off/pick up shingle samples. From the initial walkthrough to the final, we felt confident that we knew what to expect and that the services provided were the appropriate ones for our roof. The people that actually replaced the roof were thorough, quick, and kind. They were very accommodating to our need to come and go. The roof is beautiful and we are so pleased with the workmanship and the products they used. read more

Klam replaced the roof on our mid-century ranch house, garage and shed. We highly recommend Klam!! We had bids from nine companies. On the first meeting with Abel, he was very thorough, full of advice, and the bid was reasonable. Klam has a great reputation, so our job had to be scheduled a few months out. However, they sent someone to inspect the roof for potential leaks and repair them to last through the weather until the job was scheduled. We enjoyed working with Abel, Katie, and the entire crew. They were very fast, protected the plants well, respectful of the property and neighborhood, and were in and out in two and a half days. read more

Abel came out to quote the work (FULL REPLACEMENT OF ROOF) and was extremely helpful and thorough. He was able to draw out the work needed and provide details on what the work would look like. The crew was punctual and respected our home and surrounding areas while working. They did an amazing job and took extra care to ensure they left the home clean and in better shape than when they arrived. After the work was done Abel came out to do a walkthrough of the work done and took lots of pictures to show us areas we could not normally see. I would highly recommend KLAM construction for your Roof replacement! read more
