I met Michael Lallier (owner) and he was very personable and "Did what he said he was going to do". In this industry it is hard to find someone that you can trust. I would recommend Lallier Construction!

  • We worked with Christopher Stevenson to resolve issues with our house. He has been very profesional and has gone out of his way to help us.

  • This review is for Chris Stevenson. Chris is a salesman for Lallier and is the reason I'm taking the time to write this review. Chris is one of those persons that does right by the customer even if the company won't. If the roofers damage the paint or if the roofer has to cut into the siding to replace the flashing, they just tell the customer that is their responsibility to fix. Well not Chris. He put on his painting hat brought out his ladder and got to work taking care of what mess the roofers left for me and that’s just the kind of person Chris is. When he tells you he is going to take care of everything and you won't have to worry about anything that’s just what he does. Without Chris this would just be another roofing company but with Chris this company turns into a cut above the rest. If you want someone you can trust. to handle your roofing needs. pick up the phone and call Chris. And give him a chance to show you what how great it is to have a friend in the roofing business. That you so much Chris.

  • Needed a repair on roof to be done as quickly as possible. Chris was able to complete in two months time. Gutters and roof were redone but was told about installation of vents which never occurred. Still sitting in garage. Otherwise timely and professional

  • We could not have asked for a more professional and expert completion of our roof and gutters! From initial bid, to dealing with the insurance company, to working with other subcontractors, to helping us understand our options, and to making sure all details were attended to, Chris Stevenson was on top of the project every step of the way. He was responsive to every question and suggestion. Most importantly, Chris took time to understand and comply with our special circumstances. The LCI roofing crew was courteous, efficient, professional and thorough. We very highly recommend Chris and LCI Construction!

  • I contracted with LCI to have my roof replaced after the great Boulder County hailstorm of June 2018. They were very prompt and fast, did an excellent job. John Bates did a fantastic job making sure everything was taken care of and working with my insurance.

  • Lallier Construction really went the extra mile when it came to get the job done and working with my homeowner’s insurance. Andy and Page went to bat for us when our insurance kept creating road blocks in processing our claim. They took the stress out of something that was extremely daunting for a first-time homeowner. I have high expectations when it comes to my home and the service I expect. Andy and Page met and surpassed all my expectations. Lallier Construction is truly a company that takes pride in their work and taking care of their customers.

  • Great people! Would most definitely recommend!

  • Lallier did an awesome job replacing my roof after being hit by a destructive hailstorm.
    Bob initially brought samples to my house and went over the process and gave me an estimated start date. I was given a call ahead a couple days before for the scheduled start date. The job took a couple days and I never knew they were there. The finished job looks great.
    Since the job was finished, we have had several high wind days and a few snow days. The roof still looks perfect and there is no sign of a leak (neighbors had a leak). Thanks again Lallier.

  • Our experience with Lallier Construction was absolutely refreshing. We have had very serious issues with many contractors this past year. We were very pleased to meet an honest company run by an honest man. The crew that installed our gutters and downspouts are above all other crews that we have dealt with this past year. They were professional, courteous, and respectful. They cleaned up everything on our property before leaving. I highly recommend this company!

  • John and Chris held true to their word and focused on the commitment they made to me at our initial consultation to control project costs to within the confines of the original budget. My roof replacement project was completed very quickly and efficiently upon delivery of the materials to our SFR and the finished product turned out great. I would highly recommend you reach out to them for a consultation.

  • LCI replaced my roof after a hail storm and did an excellent job! They were timely, professional, safe, and did high-quality work. I really appreciate them taking care of everything without me having to make a hundred calls or take hours to organize the job. They were great and I would highly recommend them!

    Melissa M.
  • John Bates and others at Lallier were great to work with. They got me a new roof in a complicated situation where they had to work with the former owner and his insurance company as well as me, as the new owner, and my insurance company. They did excellent work and even repaired the roof of a shed too while they were at it.

  • First, right after the big hail storm of May 8 here in Golden, I researched and then called LCI because of the reviews and their reputation. I was not disappointed. John B**** headed our project and was very kind, thoughtful and honest. He stuck with us until everything was back as it was before the storm. He even came one Saturday on his own time! Such an awful storm is never a pleasant experience, but we were well taken care of.

  • Did an excellent job! I am happy with everything that happened!

  • Two years ago, LCI replaced my roof in preparation for solar panels. They did an excellent job of coordinating their work with the solar company and installing a high quality roof. After the hail storm in May 2017, I had to have another roof replacement. I contacted LCI without hesitation. Again, they did a good job on the roof, as well as coordinating with the insurance company and contracting with a solar company to remove and replace the panels. My only frustration arose when there was a long delay in correcting a few minor issues in order to appease the city inspector. However, John Bates remained diligent for as long as it took to get it done. Further, LCI gave me a discount to compensate me for the inconvenience. I would definitely recommend LCI to others needing a roof replacement

  • We were hit by a storm this summer and needed to have our roof replaced along with many other homes in our community. LCI was great to work with on our replacement. They were in and out in one day, very clean and efficient with the work they completed.

  • My initial contact with LCI was via referral from a coworker. Then, I met Louis M., who was an amazing homeowners claim rep for LCI. He was very responsive, answered emails and calls very timely, and was wonderfully communicative through the whole process of an Insurance Claim Roof Replacement (my first ever home claim). He was there for the insurance adjuster inspection and fought to get what we needed from the insurance company. The roof looks fantastic and is now up to current codes. Installation took one day, with minor fixes/touch ups occurring afterwards. Thank you Louis for all your hard work and making this otherwise stressful event a pleasant experience.

  • I'm a retail property manager with 10 years experience. Working with LCI has been a unique experience. They really go the extra mile for their clients. The roofing experience made it so much easier with absolutely NO change orders or hidden fees.

  • No hidden costs. Met all commitments. Super clean up, very efficient. I don't give 5 stars easily but these guys deserve it!

  • Due to a recent hail storm, I was in need of having to replace my roof shingles. My brother recommended Lallier Construction Inc. He said they had done a good job with his roof 3 years ago and that I should call them, so I did. I sent them an e-mail after hours on their web site and they promptly called me the next morning. We set up a time to meet at my house the next morning and the contractor was right on time. He explained the process of replacing the roof shingles, the different type of shingles available, and the different warranties each shingle carried, depending on life expectancy. The contractor inspected the roofs and told me they could have the house and both garages re roofed in one day. He suggested putting in roof vents to help keep the house cooler in the summer, which he said would be no extra labor. We set up a time that was convenient for me the following week. The day of the job the crew was here and working by 7 am. My swamp cooler was bad and Lallier's contractor told me if I bought a new one they would install it for me at no extra charge. By 6 pm they were done completely with the job, cleaned up and off the property. It has been really an enjoyable experience to work with a company that did what they say they would do! I made all decisions on what product I wanted, the time I wanted them to do the work and they fulfilled all my requests. No stress, no pressure, just a load off my mind on one more thing that I had to deal with. I remember the day it hailed and how all I could think about was the amount of trouble it was going to be to get the roof replaced. Now that Lallier Construction has finished the job, I found out what it is like to work with a good company and how easy they made it for me. When it comes to home improvement I would recommend Lallier Construction Inc. to anyone in need of help. They were prompt, courteous, polite and took very good care of me.

  • Chris from LCI helped me replace my roof which had been damaged by hail in May. He walked me through the whole process and was really knowledgable about how to deal with the insurance company. A few weeks later the crew replaced the roof on my house and shed. I was very impressed by the craftsmanship of the installers and they were very thorough about clean up - no trash or material was left behind.

  • Responsive, clean and efficient. While selling my home the inspector found some damaged and defective shingles, I called LCI and was put in touch with Jeff Quimby. He was exceptionally understanding to my urgency of a timely roof replacement due to a pending sale. His crew showed up promptly at 7 a.m and went straight to work. The job was done and cleaned up in a day and a half, no debris from the roof being replaced on the property. Just a beautiful new roof for the buyers, I'm a little sad I'm not going to get to enjoy it. Anyway, Jeff kept me up to date through texts and phone calls before, during and after completion of the work. He was great to work with and I am planning on using LCI again in the near future for some minor repairs on my new home.

  • Due to hail damage we were in the market to have our roof replaced. We had wood shake shingles and wanted to replace them with more durable and three dimensional looking laminate shingles. We chose Lallier Construction to help us accomplish this. We could not have been happier with this company. Our representative, Andy Coria came out to our house and helped us decide on what type of shingles to select. He also provided us with a list of houses to look at so we could see certain shingle colors on a roof rather than just a sample. He was extremely knowledgeable on all of the products and what would be best for our house. He was also very thorough in explaining how the roof would be taken off and replaced. If we ever had any questions he was always available to assist us. The crew that came out to install the new roof was very friendly, reliable and professional. They did beyond quality work and took care of issues that needed to be fixed that we did not know about prior to the roof coming off. Andy was also there during the installation to answer our questions and oversee the project. With such a mess of pulling off the wood shake shingles and installing a new roof the yard did not even show they were there. They did an excellent job with clean up. We have already referred many people and without a question would recommend Lallier Construction to help you with your roofing needs.

  • Kudos to Lallier Construction and Justin for my recent reroof project. They were able to accommodate my needs, timeline and financial arrangements (cash job)! The roofing crew and trailer arrived as expected, they were polite and professional and the cleanup was awesome. You'd never know they were here. After 30 years in the Roofing industry myself, I appreciate a job well done!! Thank you Justin and Andy.

  • We had Lallier construction Inc. do our roof and skylights' Chris and Andy the boss both came through with what they promised us. Most company’s will promise you things and not go through with it, but this company, made us very happy and did what they said. Lallier Construction Inc. said that it was important that the customer is happy.

  • I called two different roof companies that did not call back after several days of waiting. Finally, I called Lallier construction and they contacted me a day or two later. They fixed a leak in our roof and improved other areas as well. They also made a no-cost visit to review the issue (crawl into the attic) before I agreed to anything. They performed much work, left the house, not knowing whether I would want their services or not. Five star performance in my book. Very friendly also.

  • We were trying to sell our house and the inspector brought up items on our roof that we may want to have looked at. LCI came over and took care of various items on the roof as well as gutters. They did a great job and really knew what they were talking about. Having a letter from them stating the roof was good helped the selling process along. We are planning on having LCI do some work on our new house as well.

  • From estimation to walk-through at completion, my roofing and gutter project exceeded my expectations. I saw the LC team working on roofs in my neighborhood (Potter Highlands) and contacted Jeff Q for an estimate. He was my contact throughout the process: scheduling, picking materials, re-scheduling due to wet weather. He was always keeping me posted on scheduling, without me having to track him down. Tear off, re-sheath, dry cover, vent covers, flashing and shingles all in 1 day (8 man crew). Site was very clean when completed, some asphalt granules but that is to be expected when tearing off 3 layers. Arranged for warranty through Owens Corning, provided transfer documents to buyer while under contract. Very professional, very communicative, and very affordable. Great experience.

  • Colorado is Mother Nature's playground. This summer she dealt some fairly severe storms that required we replace our damaged '3 tab shingle' roof. Chris Stevenson from LCI (Lallier Construction) managed the replacement of our roof on Fillmore St. This is a local Colorado company that’s been replacing roofs for decades. Chris was extremely professional from start to finish. The initial inspection, insurance, permits, roofing crew, and final inspections were all seamlessly managed by him. The roofing crew was amazing. They completed the job in just under 2 days. Their cleanup was superb and the roof looks awesome.

  • LCI, was amazing and extremely helpful from the beginning until the end. The crew and the project manager (Ty Corbett), were very friendly and spoke normal people jargon, they explained everything very well. Even with the weather against us, they were still able to complete the projects on time. Our new roof is suburb and the paint job is illuminating. I have recommended this company to my friends and family.

  • Hail storms did my roof. Had never replaced a roof, but I worked with Chris and it was great. He walked me through everything & helped make the process make sense. He handled nearly everything with my insurance, kept me updated, and was flexible when my schedule was tough. Every time I had a question or concern, anyone I talked to at LCI was polite, understanding, and helpful. The workers were fast and cleaned up the yard well. Love my new roof & gutters.

  • On time as advertised as well as the price that was quoted. Few issues with the post job inspection with city inspector and they were rectified immediately. I highly recommend them to my friends and family.

  • They did our roof for us. They were spectacular from the beginning to the end. Page Dyer was fabulous. He walked us through everything, on point, he worked every day with us from the beginning to the end. He was truly incredible and they did a great job. The works were courteous and kind and addressed our concerns and really appreciate what they did. They cleaned up well and they did a very good job. Lallier construction has such great employees.

    Lynda N.
  • I thought they did an excellent job. They included what I requested which was an air vent/attic venting system and that was the product I had researched and really wanted that product. They were one of the very few roofing companies that I looked at that used that product and were able to install it. I appreciated that I had the roof prepared for solar panels and they were willing to work with the solar company in order to be subcontractors so they build for the cost of the roof through the solar company. That was great because I use the cost of the entire project to get a larger federal tax credit. I really appreciate working them.

  • This was the second time that I worked with Lallier Construction to repair hail damage to my house. Just like the first time the work was detailed, high quality, and a great value. My project coordinator Jeff Quimby was really easy to work with and did a super job of communicating with me every step of the way to make sure the work got done right and with no unpleasant surprises. I hope I don't get any more hail damage any time soon, but if I do, Lallier Construction will be first call I make.

    James M.
  • We were extremely pleased with the work performed by Lallier Construction this summer. Not only did the company provide a beautiful new roof, but they also assisted us with miscellaneous items, some of which they were paid for by insurance, and some we handled ourselves. New gutters, screens and painting touch ups were all done on schedule. The communication happened seamlessly, always receiving our call backs promptly.
