During the renovation of this Glastonbury property, we found that carpenter bees had done considerable damage to the fascia boards around the trim. Outdated and unvented wood was making an ideal home for nature to start taking over. We installed new soffit vents, with air intake at the gutters and exhaust at the ridge. The roof was done in OC Duration Design Sedona Canyon Duration shingles, with a solar fan and additional ice panels for winter weather.

Copper Gutter Installment in Glastonbury, CT

This home had already existing copper gutters that were worn, malfunctioning and in need of being replaced. Klaus Larsen Roofing started by tearing down those existing gutters and installing new 5-inch 1/2 round copper gutters, which had soldered seams. We then removed and disposed of the existing downspout, and in turn installed a new copper downspout into the ground. This installment came with the Klaus Larsen Standard 5-Year Warranty. This house is now looking better than ever, thanks to Klaus Larsen Roofing!

Vented Deck in Glastonbury

These owners in Glastonbury called because they were experiencing leaks from Ice dams on the front and rear dormer of the main house. The roof itself also had shingles missing. To solve the Ice dams leaks we installed a Vented Deck System underneath the new shingles. What is a Vented Deck and what does it do? A Vented Deck is a layer of insulation, furring boards, and plywood that creates air flow underneath the shingles. We first installed 1/2” Insulation board on the existing plywood deck. Next, we nailed several 4” wide furring strips on the insulation running parallel to the rafters. Then another layer of plywood does over the strips creating gaps between the furring strips for air. Lastly, the underlayment and shingles are installed as usual on the plywood. What this does is allow cold air to pass between the furring strips and take heat away from the shingles. Ice Dams are caused by heat rising to the shingles during the winter months. If there is no heat reaching the shingles from the attic, then you won’t get ice dams. With a full Vented Deck System, these owners are now ice dam free!

Glastonbury Roofers Replace Shingles on House and Shed

Klaus Larsen Roofing has completed over 70 roofs in Glastonbury and South Glastonbury alone. The house and shed roofs were replaced back in September of 2016. 2,500 square feet of shingles had to come off the roof. When the roof is off, this allows access to the plywood and replaced anything that has rotted. Next, the WeatherLock Ice & Water barrier is laid down and sticks to the plywood. This is installed 9 feet up the roof and above code. All additional plywood is protected by ProArmor synthetic underlayment. Lastly, the Starter shingles and Duration Architectural shingles are nailed down. Each shingle had a nailing area called the SureNail strip which strengthens and thickens the shingle. The owners chose Slatestone Gray and were very happy with the professional job.

Water Damage in Attic Space - Roof Repair Services

This roof on this South Glastonbury (06073) home was about 15 years old. We found some water damage up in the attic space, which indicated that moisture was being let in under the shingles. Klaus Larsen installed Estate Gray shingles with a VentSure ridge vent. This vent comes with a Weather Protector moisture barrier that provides top notch attic ventilation.
