About the Owner

Klaus Larsen bought his first apartment building in Denmark at the age of 21, renovating every single one of the 13 apartments in it in less than three years. At the age of 32, he immigrated to the US with his tools and $300 in his pocket to live the American Dream.  Little did he know those metric tools would do him little good in a country that only used inches and feet. By 1998 he was able to start his own home improvement business, becoming a roofing-only company in 2010 and Owens Corning’s very first Platinum Preferred Contractor in Connecticut. Platinum Preferred Contractors make up the top 2% of roofers in the US, and the process for their selection is meticulous, and this was quite an accomplishment for Klaus, though not surprising if you know him.

Klaus is well known for his historic work, using his ingenious creativity to update antique homes so their roofs perform properly while maintaining their architectural integrity. His attention to detail and Old World craftsmanship have earned him a reputation for helping to maintain New England’s rich history while integrating state-of-the-art roofing technology into it’s homes.

Today, Klaus and Judi Larsen run Klaus Larsen Roofing as a small, friendly company, where employees and customers alike become part of the Klaus Larsen family.

    Saw you in the news, donating a roof too a veteran. Being a veteran myself, that touched me. Also, seeing the Klaus is from Denmark, touched home with me. I was born in Denmark, and came too the US, in 1953. I didn't get any other quotes.

    I saw the piece about what your company is doing for that veteran in West-port. I think that is awesome and I will definitely use your company when I need a new roof. I put the last one on myself having been a roofer but I am now 62 yrs old. Plus the next one will be a removal as I have two layers. I just want to say thank you for helping that elderly couple and I will be calling you in about 5 years. It is people like you that make the state a better place. Never change what you do.

    Researched a few companies that had exc. customer satisfaction, AAA+ at BBB, and good customer reviews. Came down to 2 companies. KL (Mike) was first quote. Told him I would talk to him before I made a final decision. He followed up and he worked with me on price and materials. I would say Mike got KL the job. I am very happy I chose KL.

    One thing I liked about Klaus, compared to others, was that his price included all materials and repairs which might need to be made. Other contractors would charge extra if they discovered damage to sub-roof.

    Replacement of a Leaky Roof in Newtown, CT

    The roof was only fourteen years old, but was experiencing leaking. We found that the primary source of water intrusion was originating from the bottom of a valley. Part of this project entailed removing all prior roofing materials from the bottom of the valley, as well as the bottom 3-4 courses of siding from the adjoining wall. We then covered all exposed decking with new Ice & Water shield, and ran the membrane up the side wall of the house. In addition to Estate Grey shingles, Klaus Larsen installed new drip edges, step flashing and replaced the siding.

There was ample damaged plywood decking that needed replacing as well as re-securing with ring-shank plywood nails. Then, we laid down Owens Corning Weatherlock G Ice & Water from all eaves, valleys, chimneys, skylights, and roof/wall intersections to ensure that no moisture passes through the roof and into the home. Then, we installed Started Shingles along the entire outside perimeter of the roof and followed with Owens Corning TruDefinition Duration Shingles in the color Estate Gray.
