Colonial Style Roof Replacement in Granby, CT Colonial Style Roof Replacement in Granby, CT

This Colonial style home built in 1980 was recently damaged in a hail storm and in need of a roof replacement. We tore off 1 layer of existing roofing material and replaced 5 layers of damaged plywood decking. We then installed 3 rows of Ice & Water Barrier near all eaves, valleys, chimneys etc. We installed a slate gray asphalt shingle which enhances the homes curb appeal. We finished by removing and replacing the flashing around the chimney with brand new copper flashing. This home is now safe and secure, thanks to Klaus Larsen Roofing!

This single-family home in Granby, CT was in need of new siding and trusted Klaus Larsen Roofing to handle the job. We started by removing the one layer of existing siding. We then wrapped the entire house in Tyvek synthetic house wrap and taped all seams. We installed Mastic Carved Wood 44 Siding in the color Quiet Willow. We installed Mastic lineal trim around all doors and windows. We finished by installing a Vinyl soffit beadboard to match the siding in the entryway ceiling. This house is now looking its best, thanks to Klaus Larsen Roofing!

Expert roofing contractor serving Granby, CT

While roof leaks, roof wood rot, missing shingles, or storm damage may not seem like a big deal, roofing problems can become more severe and call for costlier, more complicated repairs the longer you wait to resolve them. And if the damage is too severe to repair and it is time for a new roof, it is better to act even sooner. If left unaddressed, roofing problems can spread to other areas of the home, causing water intrusion, pest infestations, poor energy efficiency, interior leaks, and more. But whether your home needs roof repairs or a roof replacement, the expert roofers at Klaus Larsen LLC are the best in the business and will make sure you're left with results that you can be proud of.

No matter how big or small your roofing problems, including roof storm damage, roof leaks, broken shingles, or roofs that have reached the end of their lifespan, our experts can diagnose these issues with on-site roof inspection! We can examine the system at every level and recommend solutions based on your home's unique needs. We also offer several different roofing materials:

Water management systems are designed to protect your property from structural damage, basement flooding and leaking, water intrusion, siding issues, and more.

So you can count on the longevity and reliability of your covered gutters and leaf covers for years to come!

Job Stories From Granby, CT
Historical Home Restoration Services in Granby, CT

Over the years Klaus Larsen has restored many historic homes in Connecticut. One such home was this house in Granby. It was built in the 1750’s and had two layers of shingles and most of the plywood was rotten or damaged. When our crew arrived, they installed 41 sheets of plywood on top of the old Tongue and Groove boards. Before the new underlayment when on, the flashing was replaced on both chimneys with lead flashing. Then the Ice & Water barrier and ProArmer underlayment were installed on top of the plywood. Finally, the 50-year Duration Shingles were nailed onto the new roof deck. The Duration shingles have a strong nailing called the SureNail strip that enables the shingles to withstand winds up to 130mph. The Owners chose the Estate Gray color and can now enjoy a new roof with a new strong plywood foundation.
