Here was an elegant Colonial located in Farmington, CT. The roof was over twenty years old, and the issues it had were beyond simple repair. As a part of this homeowner's full roofing system, we installed a Solar Fan, skylight flashing and all new vents to keep air moving throughout the interior of the home as well as the attic area.

At this home located in Farmington, CT we completely replaced the old roof with a brand new Owens Corning roofing system. We first tore off the layer of existing roofing materials and replaced any damaged plywood decking. We then installed three rows of Owens Corning Weatherlock G Ice & Water Shield from all eaves, valleys, and around the chimneys. To ensure complete moisture protection we laid down ProArmor Synthetic Underlayment, a durable tear-resistant material engineered to repel water and adhere to the roofing surface. To finish off this complete roof replacement we used Owens Corning Duration TruDefinition Shingles in the color Driftwood.

Job Stories From Farmington, CT
Roof Repair and Replacement in Farmington, CT

To alleviate this leaky roof in Farmington, CT we replaced it with an Owens Corning Life Time Roofing System. We also flashed the skylights, so there would be no future water penetration there. All delaminated plywood was replaced with new CDX plywood, and Ice & Water Shield was added to all eaves as well as a valley. This home is ready for a New England winter!

I have noticed it looks like a couple of shingles have come loose on the roof.
Project Location: Farmington, CT
I live in a two story Cape Cod with an attached garage. The house was flipped in 2014 prior to my purchase of it. In our first or second winter, we had ice dams develop over the bedrooms upstairs, causing a small leak inside softening the sheet rock. We have since gotten a roof rake to prevent ice dams accumulating, but I was interested in getting a quote to re-do that part of the roof and add some additional protection to that area. The shingles were newly installed in 2014 on that part of the house. My other possible project was replacing the older shingles on the back of the attached 2 car garage. New shingles were placed on the rest of the house (all of the house and only the small front of the garage) but we also have had some small leaks in the garage that I would like to prevent.
