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 required a full underlying structure rebuild to make it all one plane. With a foundation now providing support underneath, the finished roof turned out fantastic and much sturdier. We understand that every roof is different, and at Klaus Larsen we are always willing to adapt to unforeseen issues.

Originally known for its brownstone quarries and shipbuilding, Portland is one of Connecticut's most historically rich cities, and is one of many towns we've brought our craft to. This project entailed the tear off and recycling of one layer of shingles, followed by the installation of a roofing system (insured for 50 years by Owens Corning). The underlayment we use is completely resistant to tear, and provides an extremely water tight seal. We are very proud of this job!

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

This homeowner in Portland, CT was experiencing leaks from heavy rains, so they reached out to us because their roof needed replacing. We installed a full Klaus Roofing System, all in one day! Even the snow couldn't prevent our dedicated team to provide our WOW! Service for this homeowner The Klaus Roofing Way! 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 choose the shingle color Granite Black for their new roof.

Roof Repair & Gutter Replacement in Portland, CT

Klaus Larsen removed all existing gutters & downspouts from the rear and front of the house, and installed new 5” white aluminum seamless gutters. We also removed the bottom two courses of vinyl from both areas between the garage doors, to expose the concrete and achieve a uniform siding height across all four sections.
