Southington, CT Roof Replacement
Lou from Southington, CT, is a loyal customer of Klaus Larsen Roofing. We previously installed a new roof on his last home, so when he purchased a new house with a 30-year-old roof, he knew exactly who to call. Returning to the experts he trusts, Lou contacted us to give his beautiful new home the refresh it needed. At Klaus Larsen, we take pride in delivering the best for our customers. When we stripped down Lou's old roof, we replaced any rotting or damaged boards with fresh Klaus Plywood, ensuring a strong foundation for the new roof. To protect this base, we applied several layers of seals to keep the plywood in top condition and safeguard his home. First, we used Sealoron XT Deck Tape to secure the plywood boards while allowing for breathability between them. This tape is the first line of defense, preventing water from seeping through any gaps. Next, we applied Sealoron XT Ice & Water Shield to the edges and vulnerable areas of the roof, providing extra protection where it’s needed most. Finally, the Velora One Roof Underlayment was installed across the remaining surface, adding a crucial barrier between the shingles and the plywood. For the finishing touch, Lou chose IKO Dynasty shingles in Granite Black—the best in the industry—to complete his home's fresh, modern look. Another successful project done the Klaus Roofing Way!

Roof Replacement in Middletown, CT
This beautiful home is owned by Paul in Middletown, CT. Paul had his roof done 26 years ago, and although there are no leaks, the shingles are curling and even falling off. It's time for a refresh! He contacted us at Klaus Larsen Roofing where we provided a free inspection and estimate for his home's roof. From there, we proceeded with the roof replacement process and provided Paul with a roof that will last for the rest of his time as a homeowner. He chose the color Cornerstone for the new shingles. The IKO Architectural shingles used in our Klaus Larsen roof replacements come with an anti-algae guarantee, featuring copper-coated granules embedded into the shingles to prevent unattractive black stains, streaks, and discoloration. These shingles are tear-resistant and Class 3 Impact resistant, ensuring they stay firmly in place. Done The Klaus Roofing Way!

Roof replacement in Wethersfield, CT
A beautiful transformation for this home's roof in Wethersfield, CT with a full Klaus Larsen Roofing System! This home's asphalt shingled roof was over 20 years old and in need of a replacement. We first replaced any damaged plywood and renailed the existing decking with Ring Shank Nails, a higher quality nail that is a cross between a nail and a screw and won't come out in high winds. We then laid down our Klaus Larsen Roofing SealoronXT Ice & Water self-sealing membrane to create a moisture barrier between the decking and the shingles. We also added 100 extra feet of Ice & Water for the lower slope roof on left rear of house. For even more protection, we installed our own Velora One Underlayment, a high performance synthetic underlayment designed to protect the home in even the most severe weather. We also took the extra step to protect the home by taping the plywood steams with our all-weather SealoronXT Deck Tape. It's the Klaus Roofing Way! To top it off, for new asphalt shingles, we installed IKO Dynasty Architectural Shingles featuring a 1-1/4" nailing area made with a tough reinforcing woven band for incredible nail-holding power to protect the home against Mother Nature's fury. The homeowner choose the shingle color Cornerstone for their new roof.

A close friend who had a Klaus Larsen Roof installed on their own home couldn’t stop raving about the quality of our work and the professionalism of our team. Taking her friend's advice, Carol contacted Klaus Larsen Roofing when she noticed the telltale signs of roof damage—leaks, holes, and 15 years of wear and tear.

At Klaus Larsen Roofing, we understand the unique challenges of flat roofs, from ensuring proper drainage to using materials designed to withstand the test of time.
