Job Stories From Windham County, CT
Leaky Culprit: Chimney Flashing in East Hampton, CT

This East Hampton, CT house was experiencing leaking during heavy downpours. During our estimate, we found that it was attributed to worn flashing around the chimney, which was letting in moisture. During a roof replacement, we inspect and seal every crevice so that your roof will perform how it's supposed to.

Roof Repair and Replacement in Chaplin, CT

This project in Chaplin, CT involved two attached log cabins. One had a roof that was pushing 25 years, while the other was replaced in 2002, but was leaking pretty badly. The new roof was completed in OC True Def Duration Desert Tan shingles, which were installed on top of Ice & Water shield, new decking and a synthetic underlayment. The chimney was flashed with copper.

Leaking Vent & Roof Repair in Dayville, CT

Not all leaky roofs are irreparable. Most have reached an age where a full replacement is necessary, whereas others have problem spots that can be rectified with a well planned repair. This home in Dayville was getting close to needing a full replacement, however we concluded that a patch repair would be a cost efficient, and appropriate solution. The leak here was concentrated around a bathroom vent, whereas the rest of the roof was completely operational. We also discovered that there was some plywood around the vent that was black and spongey.

First we removed 100 sq. ft. of shingles from the area around the bathroom vent hoot. Klaus Larsen replaced the delaminated plywood decking and incorporated Ice & Water shield with an underlayment. For the outermost layer, we used Duration shingles from Owens Corning. This repair came out excellently, and the leak has been stopped.

Small Roof Replacement and Repair in South Windham, CT

This is what is called a “coachman's house,” located behind a large Victorian home in South Windham, CT. These smaller structures were known to house caretakers, and make for a perfect, roomy garage after renovations. For this job we tore off one layer of the old slate roof, and replaced it with an Onyx Black asphalt Owens Corning Roofing System. We also repaired the front trim, and used primed pine and crown moulding to match the existing profile as closely as possible. Maintaining historic integrity, while providing the right protection is absolutely essential on these types of projects.

Free Roofing Estimate in North Windham, CT

This home had 2 layers, with some bad leaking, as evident in the wood of the attic. There was also a lack of ventilation, which was not helping the condensation and moisture issues here. We installed a full Owens Corning Roofing System with Duration Driftwood shingles to totally alleviate the leaking. Included in this system was a SmartVent along the eaves, garage and main house. New vent pipe boots and chimney flashing also ensure no moisture penetration in these smaller, less visible areas. All work was done in a day, and the property was left fully cleaned up.

New Plywood and Roof Replacement in Chaplin, CT

Many times we come across homes that were built in the 40's and 50's that don't have any plywood under the shingles. Back then, builders would use thick boards called Tongue and Groove Boards for the roof deck. However, these boards can be a problem if there are wide gaps in between each of them. Wide gaps cause roof nails to poke through and hang in mid-air. If the nails are not secured to the deck, then the shingles can fall off or allow water penetrations. So we installed a new 1/2" CDX plywood deck over the existing Tongue and Groove boards. Now that the Owens Corning shingles are installed, the owners can enjoy a 50-year roof they know is firmly installed and looks great. (color: Quarry Gray)

Large Garage Roof Replacement in Plainfield, CT

This large garage in Plainfield had a 29-year-old roof, far beyond a three-tap roof’s normal lifespan. The owner was well aware of the fact and decided to replace the roof right away. Several contractors came out to look at the job and the owner chose Klaus Larsen to replace the roof. We first tore off the roof and inspected the plywood. Many times there is rotten plywood underneath that needs to be replaced. However, at this job, all the plywood was in good condition. We always install 9 feet of Ice & Water barrier and cover any additional exposed plywood with Synthetic ProArmor Underlayment. To finish it off, the owner chose Onyx Black Duration Shingles for the roof. Garages may be a lower priority for most homeowners but even garages need new roofs.

Roof Replacement in Rural Ashford, CT

Surrounded by trees and down a quiet road was this home in Ashford. The house itself had an old roof that needed new bathroom vents and a ridge vent. The owner wanted the job to be thoroughly cleaned up afterward. Our crews showed up early in the morning and got to work. When our crews install a roof, there is a system in place. Owens Corning had a system of layers that protect the roof. First, the Ice & Water barrier protects the roof from Ice dams. Then the ProArmor Underlayment protects the plywood from water but still is breathable so moisture can evaporate. Finally, the 50-year Duration shingles go on with purpose made ridge vent and cap shingles. Last but not least, the entire area was cleaned up and the owner only found two nails on their property. The owner was very impressed at the crew’s efficiency and now enjoys a roof that will last a lifetime.

Snow & Ice Damage on Roof in Canterbury, CT

Living in the North East, ice dams are one of the most common reasons we are called out to look at a roof. This home in Canterbury had thick ice dams that were causing leaks in their home. What can be done to prevent ice dams and what can be done to prevent ice dam leaks? 

When we replace a roof we install two products that specifically protect your home from ice dams: Ice & Water barrier and Ventilation products. If the roof is old, we always tear off the old roof before putting a new layer down. This allows us to replace any rotten plywood and install Ice & Water barrier. We lay 9 feet of Ice & Water up from the bottom edge of the roof. The Ice and Water barrier sticks directly to the plywood and protects the wood and ceiling from water that is kept on the roof by ice dams. Next, we install ProArmor synthetic underlayment and Owens Corning Duration shingles. However, we do not just want to stop ice dam leaks, we also want to reduce the chance of ice dams.

First, What causes ice dams? Ice dams are caused by the warm air in your house that rises and passes through the roof. It heats the roof up and melts snow and ice that is sitting on the top. The water then slides down the roof until it reaches the edge where there is no heat. It will then refreeze and build up and build up forming and ice dam. If we make the attic closer to the same temperature as the outdoors, then the home will be less likely to get ice dams. We do this by improving the ventilation. This brings in cold air from the outside and take the warm air out of the attic. Now that the attic is cold, the snow on the roof won’t start melting and forming ice dams. At this particular home we installed a solar attic fan to regulate the temperature in the attic. It tracks the temperature of the attic and will turn on if the attic gets too hot. Now that we have installed protection and ventilation the owners can relax and no longer worry about ice dam leaks.

Roof Replacement for House + Car Garage in 2 Days!

In December of 2016, the owner of this home called us out to look at a property he managed. It was a large old farmhouse with an 3 car garage attached by a long breezeway. Altogether there were more than 5,000 square feet of shingles that needed to be replaced. Also, the shingles did not match each other because the roofs were not all replaced at the same time originally. When we inspected the home, our sales consultant checked the plywood and found tongue and groove boards with large gaps. The problem with large gaps between the boards is that nails from the new shingles would not be anchored to any wood and therefore void our warranty and cause shingles to fall off. So when we came to start the project, we covered the old boards with new 1/2' plywood. Then we installed nine feet of ice and water barrier. We then nailed down Synthetic underlayment above the nine feet of Ice and Water Guard to completely protect the plywood. Finally, we nailed down the Owens Corning Duration shingles. The entire roof is now the same color and designed to last for decades!

Partial Roof Replacement on the Central Assembly of God in Wauregan, CT

A Pastor from the Central Assembly of God in Wauregan, CT contacted Klaus Larsen because the fascia was leaking. The fascia is the wooden board or other flat material that covers the end of rafters. To solve the problem, the damaged plywood was replaced. Three rows of Owens Corning Weatherlock G Ice & Water shield was installed to prevent moisture from entering the interior. White, aluminum drip edge/rake was installed the entire outside perimeter of the building. CertainTeed Landmark Pro shingles were used to match the roof slopes. Each of the materials used were high grade and guaranteed to keep unwanted moisture from damaging the roof in its entirety.
