On this Lebanon property, we used the Cambridge line of Harvard Slate IKO shingles to make a beautiful country home even more beautiful. Our 'after' image was taken awhile after the completion of this project, but the luster of the shingle and the 'new roof look' remains.

The black streaks on this Lebanon roof are from a blue-green algae spore that is prevalent in humid climates. We don't recommend cleaning your roof with abrasive chemicals, as they will harm the shingles. The metallic coating on chimney flashing helps to deter algae growth, but modern algae-proof shingles are your best bet for prevention.

Job Stories From Lebanon, CT
Roof Replacement in Lebanon, CT

A beautiful transformation for this home in Lebanon, CT! This homeowner reached out to us because they were experiencing leaks from their 30 year old asphalt shingled roof. They reached out to us to install a full Klaus Larsen Roofing system. Check out the before and after and what went into this new roof replacement. To protect the home and prevent leaks in the future, we first replaced any damaged plywood decking and laid down our Klaus Larsen Roofing SealoronXT Ice & Water self-sealing membrane to create a moisture barrier between the decking and the shingles. 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 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 chose the shingle color Atlantic Blue for their new roof.

Shed Roof Replacement in Lebanon, CT

We previously roofed a home and shed in Lebanon, CT and unfortunately had to go back due to a tree falling through the shed. The crew replaced the sheet of plywood where the tree punctured it. We used IKO Dynasty Shingles in Granite Black to complete the new shed roof. 

KRS Roof Replacement in Lebanon, CT

This home in Lebanon, Connecticut was in need of a new roof and Klaus Larsen Roofing gave them just that! To begin this job, we removed the existing layer of roofing material. Afterwards we cleared away all debris and used a magnetic roller to ensure that there were no loose nails in the homeowner's lawn. Next we inspected the plywood decking, and found that 2 sheets of plywood were visibly damaged and in need of a replacement. With the decking process finished, we installed two rows of IKO Gold Shield Ice & Water Barrier. At the seams we installed a 4" self-adhering flashing tape and installed a synthetic underlayment to ensure protection from the elements. For shingles, we installed a Klaus Roofing System using IKO Dynasty Architectural Shingles in the Driftshake colorway. To finish the job, we installed a Shingle Vent II ridge vent that ensures the home's attic is well ventilated. This home is now complete thanks to Klaus Larsen Roofing!

Complete Roof Replacement in Lebanon, CT

The owners, who live in Lebanon, were looking to replace their roof when then called us to give them a free estimate. After looking at all their options, they chose Owens Corning Duration Shingles. (Color: Chateau Green). While the roof was being replaced, we also replaced the ridge vent on the peak of the main house. The chimney flashing and vent boots were also replaced because these are easy water penetration areas if not properly flashed. Lastly, Premium Ice & Water shield was installed on the shed dormer roof due to its flatness. Low pitch roofs shed water and ice more slowly and require extra protection to prevent leaks down the road. The entire roof system is guaranteed though our Owens Corning Platinum warranty for 50-years.

Roof Repair & Replacement in Lebanon, CT

On this ranch in Lebanon, CT we provided another Owens Corning Life Time Roofing System, with its 50 year full Coverage Warranty. On this job we did a good amount of structural repair, including removing and replacing the fascia/rake boards with Kleer composite trim boards. In addition, we removed a kitchen vent as well as a small, secondary chimney. The main chimney was redone with leak proof flashing. The resulting roof is practical, efficient and far less cluttered.
