At this ranch home located in Windsor, CT we completely tore off the existing single-tabbed shingles and replaced them with Owens Corning Duration shingles in the color Onyx Black. We removed and replaced any damaged plywood decking and installed new aluminum drip edge along the entire outside perimeter of the roof. To give the attic of this home great ventilation we put in new Ventsure Ridge Vents to provide top-notch consistent attic ventilation. Ventilation is one of the most important parts of keeping a home moisture and mold free. in addition to the new roof, we also put in new 5" aluminum seamless gutters and downspouts to allow water to properly run off the roof. With a new roof and attic ventilation, this homeowner can now be worry-free come this winter!

This multi-family Victorian style home located in Windsor, CT was in desperate need of a new roofing system. This home had old style single tabbed shingles which are known for causing leaks. We completely stripped the old roof and removed and replaced 5 sheets of plywood decking. On top of the new plywood decking, we laid down Owens Corning Ice & Water Shield to protect the home from outside moisture. For shingles, we used Owens Corning Duration TruDefintion Shingles in the color Desert Tan. Attic Ventilation is especially important when it comes to the well-being of your home. We installed a VentSure Ridge Vent to provide top-notch consistent attic ventilation.

Job Stories From Windsor, CT
Roof Replacement in Windsor, CT

An owner of a home in Windsor, CT had a leaking roof. Although the roof was relatively new, water was pouring down one of the walls. When we came out to provide an estimate, we recommended the entire roof be torn off and replaced. Our crews started early in the morning and tore off one layer of old shingles. Next, they installed nine feet of Ice & Water barrier on the roof. Ice & Water was also applied around the chimney and bathroom vents. Above the Ice & Water, they installed ProArmor Synthetic Underlayment. Also, the flashing around the chimney was replaced with new lead chimney flashing. Lastly, the new Owens Corning Duration Shingles were installed with our Platinum Contractor 50-year full warranty (Color: Slatestone Gray).

I am in need of repair to my roof. There is a leak from the flashing around my chimney. A stain is visible on the ceiling in my living room and I would like the leak repaired before the damage gets worse. I would do the repair myself, but I am getting too old to get on my roof. The house is a raised ranch, so there is easy access to the roof. The roof is older and will need to be replaced in the near future, but for now I would like to get the flashing repaired. Please contact me.
