Roof Replacement in Portland, CT Roof Replacement in Portland, CT

Carol from Portland, CT, knew it was time to replace her roof when her flat roof began leaking, and she didn’t have to look far for a recommendation. 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.

Recognizing that a flat roof requires special attention and expertise, Carol knew she needed a roofing company that is experienced with this special situation. 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. This beautiful IKO shingle color is Brownstone and compliments her home perfectly. Carol can rest easy knowing that her new roof will not only solve her current issues but also provide long-lasting protection for years to come. The Klaus Roofing Way!

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.

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.
