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.

The team at Klaus Larsen gave a World War II Veteran a new roof! Watch Video »
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.
This home was located on sprawling Bantam Lake in Morris, CT. The scope of this project included aluminum seamless gutters and Owens Corning Duration Driftwood shingles capping off a fully vented roofing system. We used Owens Corning ProArmorShield synthetic underlayment to protect the deck, and flashed the chimney with copper. Per the homeowners request, we installed a NuTone bath-vent with flappers and a Lomanco ridge vent. For improved ventilation, we added Cobra intake vents at the fascia boards.

The three layers of reinforced, woven fabric makes for a roof with ultimate staying power. We know you'll love this shingle as much as we do.
Here was an elegant Colonial located in Farmington, CT. The roof was over twenty years old, and the issues it had were beyond simple repair.

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.

Some jobs have unexpected obstacles, like on this house in Portland. Upon removing the old roof, we found a gaping hole in the original construction.

This was a project from 2013, that brought us to Wethersfield, Connecticut. Before this home had a Klaus Larsen roof, the day was gloomy and bleak. We installed Owens Corning Onyx Black Duration shingles for the new roof and sunshine came with it. Disclaimer: Our work is not guaranteed to alter atmospheric conditions, but it certainly may help.
For this Wethersfield, CT project we tore off the existing roofing materials to be recycled. All debris was meticulously cleaned up, including nails which were picked up by a magnetic roller. In order to create a full moisture barrier, we installed three rows of Owens Corning Weatherlock G Ice & Water shield in addition to Synthetic Underlayment. This is a durable, tear-resistant material engineered to repel water and adhere to the roofing surface. We finished the project by installing a Copper Cat Algae Terminator on the rear roof above the porch. This double-sided copper strip prevents any growth of algae, moss or mold.
For this roof replacement in Hartford, CT we completely stripped and replaced this detached garage roof.

For roofing shingles, we used Owens Corning Oakridge Shingles in the color Estate Gray and topped it with ProEdge Hip and Ridge Shingles on all ridges and hips.

At this cape-style home located in East Hartford, CT we completed a full roof replacement on the main house as well as the garage. To provide total moisture protection from outside elements we installed Weatherlock G Ice & Water from all eaves, valleys, and around chimneys and roof/wall intersections. To keep the integrity of this home we installed brand new Owens Corning Duration Shingles in the color Slatestone Gray. To protect the chimneys from water damage we removed and replaced the flashing with new lead flashing. This home needed a new bathroom exhaust vent hood with a built-in damper on the roof which included a new flex duct from the fan to the hood.
Here was a roof in Glastonbury, CT that was in need of repair. We always make sure to clean up thoroughly after a job and this property was left free of any nails or old shingles.
During the renovation of this Glastonbury property, we found that carpenter bees had done considerable damage to the fascia boards around the trim. Outdated and unvented wood was making an ideal home for nature to start taking over. We installed new soffit vents, with air intake at the gutters and exhaust at the ridge. The roof was done in OC Duration Design Sedona Canyon Duration shingles, with a solar fan and additional ice panels for winter weather.
On this tudor style home in Glastonbury, CT we encountered a steep, twenty nine year old roof with several leaks. After tear off, we replaced the rotted plywood panels and rafters.

The shingles you see here are Owens Corning Tru Def Duration Brownwood.

The finished shingles here are Slatestone Gray.
