Colonial Roof Replacement in Mystic, CT Colonial Roof Replacement in Mystic, CT

At this late 1930s Colonial-style home located in Mystic, CT we installed a brand new roof using the Kluas Roofing Way. The homeowners had just replaced their roof in 2010. However, because of improper installation and poor quality products, they needed to completely strip and re-roof their home. When we arrived at the home we first begin tearing off the old shingles. We replaced any damaged plywood decking and laid down Ice & Water Shield to protect the interior of the home. In addition, we installed underlayment to adhere to the roofing surface and repel any outside moisture. For shingles, we used architectural-style asphalt shingles in the color Onyx Black. To top it off, we installed new lead chimney flashing from around each of the chimneys on the house. This brand new roof comes with a 50-year Warranty and Klaus Larsen Workmanship Warranty so the homeowner no longer has to worry about their roof.

Garage Roof Replacement in Mystic, CT

We had replaced this homeowner's roof in Mystic, CT and they wanted to us to return to install a new roof on their garage. The homeowner also wanted to us to remove the garage's chimney which we were able to do at the same time as installing a full Klaus Larsen Roofing System. The homeowner chose IKO Dynasty Shingles in the color Biscayne to match the main house.

Roof & Gutter Replacement in Mystic, CT

This beautiful home sat in a quiet part of Mystic, CT. The roof and gutters on this house were old and needed replacing. The owner also wanted the dormers to be redone and all the trim work around the house. Before our crews started on the roof, we had our production team go to the property and put up the stone veneer on the two front dormers. Next, our roofing crews came on the scheduled date and tore off the old roof. They then immediately checked the condition of the roof deck before installing the Ice & Water Barrier. We always install 9 feet of WeatherLock G; Ice & Water, that way, we are well above where the ice dams form. Above the Ice & Water, we nail down Synthetic underlayment on the roof deck. Lastly, comes the Owens Corning Duration Shingles. The owners chose the Duration Driftwood color for their roof. Once the shingles were down, our production team did the final touches of siding, rake & trim boards, and gutters. The owners also asked us to do the stone veneer on the front wall of the breezeway. The yard was completely cleaned up afterward and the finished job came out beautifully.

Mason's Island Yacht Club Roof Replacement in Mystic, CT

How do you know when its time to replace your roof? Generally, its a good idea to get the roof replaced before the leaks show up. When it starts leaking, not only do you get large stains on the ceiling but in some cases, the paint will start cracking and peeling off. This was the situation at the Masons’ Island Yacht Club in Mystic. The cracks and stains told the owners loud and clear that a new roof was needed. When we replace a roof we not only have a process but the roofing itself is a system of layers that protect your home. First, we tore off 2,800 square feet of shingles off the roof. Then we replaced any rotted tongue and groove boards with 3/4” CDX plywood. Next, comes the Underlayment. We use Owens Corning roofing system which comes with Weather Lock Ice & Water barrier and ProArmor Synthetic Underlayment. The shingles come in three types Starter shingles, the Shingle, and Hip & Ridge shingles. The shingles themselves have a nailing area called a SureNail strip that thickens the nailing area and seals the nails once they are down. Once the entire system is down, we guarantee the roof with the longest warranty in the industry. We will even clean up the debris ourselves and remove it from the property. All nails are cleaned up and owners are paid back $1.00 for each nail left behind. Now members and owners alike can enjoy the view of the water without having water inside.

Roof Replacement and New Skylights in Mystic, CT

Many times we are asked by homeowners if their old skylights can be left as-is when we replace the roof? If the skylights are in good condition, we will work around them. However, many times we visit homes with old or even leaking skylights. In these cases, like this home in Mystic, the old skylights would have to be replaced. Here in Mystic, the garage had two small skylights on one side. We replaced the old skylights with New Velux Laminated skylights. If the Velux skylight doesn't quite fit the opening we will send one of our production crew to reframe the opening and finish off the interior!

Helping in a Historic Renovation in Mystic, CT

The John S. Schoonover house was originally built in 1800, and owned by its namesake banker. The entire restoration spanned two months and included new exterior paint, Marvin pocket windows with over twelve simulated divided lights with aluminum clad exterior, a newly paved driveway and white cedar Cape Cod picket fences. Klaus Larsen was happy to provide the new roof, as a part of this now beautifully preserved home by the coast.
