This single family home in Coventry, CT was experiencing leaking in their home and sought Klaus Larsen Roofing to fix the problem. We started the process by tearing off one layer of existing roofing materials and replaced 20 layers of damaged plywood decking. We then installed 3 rows of Ice & Water Barrier near all eaves, valleys, chimneys etc. In terms of shingles, we installed a stunning gray to compliment the color of the home. We finished the job by removing and installing brand new cedar rake boards. This home is now safe and secure, thanks to Klaus Larsen Roofing!

Job Stories From Andover, CT
RainDrop Gutter Guard Installation in Adnover, CT

This homeowner in Andover, CT reached out to us about installing our RainDrop Gutter Guard to their existing gutters. Why RainDrop? Gutters are supposed to take water away from the home. If they are clogged, water overflows and ends up running down the side of the home and eventually causing foundation problems. RainDrop provides gutter protection like no other gutter guard available. Every aspect of the RainDrop Gutter Guard is essential in its goal to provide a maintenance free & self-cleaning gutter protection system, far more advanced than anything available on the market today. RainDrop fits on every home as it's the most versatile gutter guard available. The RainDrop Gutter Guard can handle any amount of water from the worst downpour. Even high-volume valleys are no problem, which is where other products tend to struggle. RainDrop is known for its unbeatable performance and durability and is made from its own unique blend of polypropylene. This special blend of polypropylene and UV stabilizers can and will withstand the harshest storms, hottest climates and coldest seasons imaginable.
