At this Tudor style home located in New Britain, CT they had issues with their roof where some of the old singles were sliding off and leaving an exposed gap. The existing roof was over 22 years old and was due for a full replacement. We tore off the existing shingles and recycled them at the Asphalt Roof Recycling Center. Then, we inspected the plywood decking for any damage and replaced sheets which needed replacing. To ensure total moisture protection we installed Owens Corning Weatherlock G Ice & Water from all eaves, valleys, chimneys, and roof/wall intersections. We also laid down ProArmor Synthetic Underlayment to repel water and adhere to the roofing surface. For new shingles, we used Owens Corning Tru Definition Duration shingles in the color Brownwood. This old style Tudor home now has a brand new roofing system to ensure total protection through the winter and beyond.

This single-family home in New Britain, CT was in need of a roof replacement. To start, we tore off one layer of existing roofing materials and replaced one sheet of damaged plywood decking. We installed 2 rows of ice & water barrier near all eaves, valleys, chimneys etc. In terms of shingles, we installed Cambridge Architectural Shingles in the color Charcoal Gray. We finished by removing and replacing flashing on the chimney. This house is now complete, thanks to Klaus Larsen Roofing!

Roof replacement company in New Britain, CT

Do you have an older roof or one that has suffered significant damage? It might be tempting to just settle for a roof repair. After all, a roof repair is often cheaper. However, roof repair is often less cost-effective in the long run as it fails to address the root of the problem and you can easily end up in a cycle of repairs.

At Klaus Larsen LLC we generally recommend a roof replacement for older or heavily damaged asphalt shingle roofs, metal roofing, and roofs with energy-efficient shingles. A roof replacement will address the core problem and keep your home protected for years to come. A roof replacement can also provide a very immediate and noticeable boost to your home’s curb appeal.

When you contact the experts at Klaus Larsen LLC you can count on our experienced team to be on the scene quickly. We’ll inspect your roof and then work with you to determine if a roof replacement is practical given your particular needs and budget. We can then provide the quality replacement that you need using some of the best materials available from leading manufacturers. We also offer vinyl siding installation and vinyl siding replacement to protect your home on all sides.
