We had such a great experience with L&L Doors and learned that Elmer’s son(s) also own L&L Roofing Systems. If the roofing company is anything like the quality, professionalism, and pride we experienced with this family, they’re definitely worth recommending! We love supporting family-owned businesses, and it’s clear that hard work and quality craftsmanship run in this family. Wishing L&L Roofing Systems continued success!

I can't say enough good about the entire L&L team. They put a high quality roof on our flat roof office building about 6 years ago and when they came for the yearly inspection they found severe hail damage from a storm. It was a complicated process mainly due to the insurance adjuster, but Josh greatly assisted me in speaking with the adjuster many times advocating for the full and complete replacement to be paid for, and he helped me to understand all involved with multiple aspects of the job. Wendell helped to coordinate the various steps in the installation of the flat roof, shingles portion, portico and gutters, and was very helpful asking where the vehicles, dumpsters, trailers and tools could be placed at a busy office building prior to the arrival. The men worked hard in extreme heat and even some in hard rain. They left the job site impeccably clean each night. They literally were running to keep a steady pace of their hard work. There was one issue and Wendell was there within 40 minutes of my call working to resolve the situation, and it was fully resolved. They should give seminars on how work should be completed from step 1-100. I could not be more pleased with the L& L Roofing team.

We had an intermittent leak in our rubber roof that I had several people attempt to repair. L&L came out promptly and sealed all potential leak spots. We have had several extreme rainstorms since their repair, and the leak is fixed! Thanks a bunch!

We have used them at several of our locations for a variety of roof situations. Top 4 things I loved: 1) Reliable service – they showed up on time every day and finished the job as promised. 2) Responsive communication – they answered my calls quickly and kept me updated throughout the commercial roof replacement. 3) High quality workmanship – the new roof looks great and the material feels solid. I hired L and L Roofing Systems for a flat roof repair on our building and was impressed by their punctuality and professionalism. Iwould recommend them to anyone looking for a commercial roofing contractor. 4) These are genuinely friendly and down to earth people.

I had a great experience with L and L Roofing Systems. The price was fair, the crew was professional and responded quickly to my calls. They showed up right on time, worked neatly and left the job site clean. I especially appreciated how they handled my commercial roof repair with no hassle. They have done multiple roof coatings. Always prompt and professional.
