Klaus Larsen, Llc

Klaus Larsen is a roofing and exterior company with 4.8 stars from 575 Google ratings, based in North Windham, Connecticut, with an office in Exeter, Rhode Island, and a stated service area reaching into eastern Massachusetts. The company says Klaus Larsen, who came to the U.S. from Denmark, founded it, and its Houzz profile says it has served Connecticut homeowners since 1998. Its site lists Connecticut HIC #0646137. One-day roof replacements come up again and again. In April 2025 Angi reviews, one customer said Ryan and the crew replaced their roof in one day, another said the work was done at the agreed price in one day, and a third said David arrived with a drone to survey a leaking roof and laid out options. A customer that same month said the company removed a skylight another company had installed incorrectly and repaired the roof. A November 2020 Houzz reviewer said the roof was replaced in one day and cleanup was thorough and quick. On r/connecticut, a July 2025 poster strongly recommended Klaus Larsen for "Excellent workmanship, good price, and guaranteed," and a February 2026 poster said it did their roof in one day and gives a senior discount as well as 10% off for taking the contract at first presentation. A May 2025 HomeAdvisor customer said debris was plentiful around the house after the job. In an October 2019 review, a customer said an installer fell through their ceiling, the sheetrock repair took a couple of weeks and cost them uncompensated days off work, and a skylight they had warned was a size no longer made did not fit on roofing day. A January 2020 reviewer called the job fair but very costly. A June 2026 Thumbtack reviewer said the company couldn't provide an estimate for a couple of weeks. In August 2026 an r/connecticut poster said Larsen would not stop calling and texting, and in June 2026 another reported that the company began work on a neighbor's roof in Suffield, CT, on May 28, 2026 without pulling a permit. A third-party site citing U.S. Department of Labor records reports a formal OSHA inspection of Klaus Larsen LLC at 3 Main Street, Stafford Springs, Connecticut, with citations and proposed penalties.
