Old Roof Replacement in Norwich, CT

Old Roof Replacement in Norwich, CT

Old Roof Replacement in Norwich, CT Old Roof Replacement in Norwich, CT

This hipped roof in Norwich had tongue and groove boards underneath the roof instead of plywood. Boards will often be found in older homes build in the 40's and 50's. Some boards were damaged and needed to be replaced before the new Asphalt Estate Gray roof was installed. The roof, ridge vent, chimney flashing, and a flat roof section were all replaced on the same day!

This single-family home built in 1876 in Norwich, CT was in desperate need of a roof replacement. To begin, we tore off 3 layers of existing roofing materials and installed new plywood decking to the existing framing. We then installed 3 rows of  Ice & Water Barrier near all eaves, valleys, chimneys etc. For shingles we installed Oakridge Shingles in the color Estate Gray. Lastly, we removed and replaced all flashing on the chimney with brand new lead flashing. This home is now secure and better than ever thanks to Klaus Larsen Roofing!

We replaced the gutters on this home in Norwich, CT and the homeowner wanted to work with us again for a roof replacement. The asphalt shingled roof was as least 30 years old and was in need of a replacement along with the skylights. During a full Klaus Larsen Roofing System replacement is the ideal time to consider adding all new skylights, and Klaus Larsen Roofing can provide skylight installation as part of the roof replacement. It's a complete "Klaus Roofing Way" upgrade to the top of your home! 


The end result was a beautiful transformation with IKO Dynasty Architectural Shingles in the color Biscayne, chosen by the homeowner, and brand new Velux skylights. This homeowner can enjoy and trust the beauty, quality, and performance from their new Klaus Roofing System for decades to come, especially with our 50 year warranty!

Job Stories From Norwich, CT
KRS Roof Replacement in Norwich

This home in Norwich, Connecticut was suffering from a leaky skylight and old worn out shingles. 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 10 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 Castle Grey 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!

14 Unit Roof Replacement in Norwich, CT

The Klaus Larsen team was able to take on this wonderful opportunity! The Uncas Condominiums in Norwich, CT needed a roof replacement, all 14 units! After tearing off the old layer of shingles, the Klaus Larsen team got to work with replacing the old plywood and adding 3 rows of Owens Corning Weatherlock G Ice & Water to the roof before laying down the shingles! The shingles used were Duration TruDefinition Shingles in the color of Desert Tan!

The picture below shows the condos before (left side) and after (right side) Klaus Larsen replaced the roof!

Roof Repair Services in Norwich, CT

This home in Norwich had parts of the roof replaced with Owens Corning Duration shingles. The rest was left with outdated 3-tab shingles. The 3-tab roof was very old and the owners knew it was time to get it replaced. Not only were we able to replace the damaged part of roof in one day but we were able to get the entire roof to match perfectly. We knew the newer section of the roof was Owens Corning Duration because of it's iconic SureNail strip. This is a nylon strip that Owens Corning installed into their shingle. It provides an extra thickness to the shingles and helps identify the right location for the nails. Now the entire roof is fully protected and is ready to protect the home again!

Roof Replacement Process in Norwich, CT

At this home in Norwich, the entire roof was torn off along with a small flat roof section over the sun room. After the old asphalt shingles were torn off, underneath was found tongue and groove boards. We often find tongue and groove boards in homes built in the 40's and 50's. Once the roof deck was exposed, we could then access the rotten boards and replace them. Next came the ice & Water shield. We use 9' of Ice & Water, which is above code, to provide complete protection from Ice Dams. All other exposed decking is covered with Pro Armor synthetic underlayment. Finally, the shingles go up and the entire area is cleaned up. Although this roof was done in the winter, our technicians are experts in winter roofing and adjust their installation methods accordingly. At the end of the day, the homeowners get to enjoy a new roof that is guaranteed for 50 years!

Need roof replaced. There's a leak and additionally there's3 layers of shingles up there from before we bought the house. So way too heavy a roof to be safe not to mention illegal.

Homeowners insurance sent notice that we need to have a professional look at the roof to see if it needs repair or replacement. Roof has no known leakage/issues, but popped nails and other concerns indicating it may be nearing the end of lifespan. Also, need to add ventilation to the attic.
